PRECAUTIONS FOR USING LCD MODULES10.1. HANDLING PRECAUTIONS(1) The display panel is made of glass. Do not subject it to a mechanical shock or impact by droppingit.(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any inyour mouth. If the substance contacts your skin or clothes, wash it off using soap and water.(3) Do not apply excessive force to the display surface or the adjoining areas since this may cause thecolor tone to vary.(4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handlethis polarizer carefully.(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a softdry cloth. If it is heavily contaminated, moisten a cloth with one of the following solvents: - Isopropyl alcohol- Ethyl alcohol(6) Solvents other than those above mentioned may damage the polarizer.Especially, do not use the following:- Water- Ketone- Aromatic solvents(7) Extra care to minimize corrosion of the electrode. Water droplets, moisture condensation or acurrent flow in a high-humidity environment accelerates corrosion of the electrode.(8) Install the LCD Module by using the mounting holes. When mounting the LCD Module, makesure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/Ocable or the backlight cable.(9) Do not attempt to disassemble or process the LCD Module.(10) NC terminal should be open. Do not connect anything.(11) If the logic circuit power is off, do not apply the input signals.(12) To prevent destruction of the elements by static electricity, be careful to maintain an optimumwork environment.- Be sure to ground the body when handling he LCD Module.- Tools required for assembling, such as soldering irons, must be properly grounded.-To reduce the amount of static electricity generated, do not conduct assembling and other workunder dry conditions.-The LCD Module is coated with a film to protect the display surface. Exercise care when peeling off this protective film since static electricity may be generated.10.2. STORAGE CONDITIONSWhen storing, avoid the LCD module to be exposed to direct sunlight of fluorescent lamps. For stability, to keep it away form high temperature and high humidity environment (The best condition is : 23±5°C, 45±20%RH). ESD protection is necessary for long-term storage also.10.3. OTHERSLiquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subject to a low temperature.If the LCD Module have been operating for a long time showing the same display patterns the display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear.A normal operating status can be recovered by suspending use for some time. It should be noted that this phenomenon does not adversely affect performance reliability.To minimize the performance degradation of the LCD Module resulting from destruction caused by static electricity etc. exercise care to avoid holding the following sections when handling the modules.- Exposed area of the printed circuit board.- Terminal electrode sections.11. Using LCD modules11.1 LIQUID CRYSTAL DISPLAY MODULESLCD is composed of glass and polarizer. Pay attention to the following items when handling.(1) Please keep the temperature within specified range for use and storage. Polarization degradation,bubble generation or polarizer peel-off may occur with high temperature and high humidity.(2) Do not touch, push or rub the exposed polarizers with anything harder than a HB pencil lead (glass,tweezers, etc).(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers andreflectors made of organic substances, which will be damaged by chemicals such as acetone, toluene, toluene, ethanol and isopropyl alcohol.(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft materiallike chamois soaked in petroleum ether. Do not scrub hard to avoid damaging the display surface.(5) Wipe off saliva or water drops immediately, contact with water over a long period of time maycause deformation or color fading.(6) Avoid contacting oil and fats.(7) Condensation on the surface and contact with terminals due to cold will damage, stain orpolarizers. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air.(8) Do not put or attach anything on the display area to avoid leaving marks on.(9) Do not touch the display with bare hands. This will stain the display area and degrade insulationbetween terminals (some cosmetics are determinate to the polarizers).(10)As glass is fragile, it tends to become or chipped during handling especially on the edges. Pleaseavoid dropping or jarring.11.2 INSTALLING LCD MODULEAttend to the following items when installing the LCM.(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and thefitting plate should have enough height to avoid causing stress to the module surface, refer to the individual specifications for measurements. The measurement tolerance should be ±0.1mm.11.3 ELECTRO-STATIC DISCHARGE CONTROLSince this module uses a CMOS LSI, the same careful attention should be paid for electrostatic discharge as for an ordinary CMOS IC.(1) Make certain that you are grounded when handing LCM.(2) Before removing LCM from its packing case or incorporating it into a set, be sure the module andyour body have the same electric potential.(3) When soldering the terminal of LCM, make certain the AC power source for the soldering irondoes not leak.(4) When using an electric screwdriver to attach LCM, the screwdriver should be of groundpotentiality to minimize as much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of the motor.(5) As far as possible, make the electric potential of your work clothes and that of the workbenches tothe ground potential.(6) To reduce the generation of electro-static discharge, be careful that the air in the work is not toodried. A relative humidity of 50%-60% is recommended.11.4 PRECAUTIONS FOR OPERATION(1) Viewing angle varies with the change of liquid crystal driving voltage (Vo). Adjust Vo to showthe best contrast.(2) Driving the LCD in the voltage above the limit will shorten its lifetime.(3) Response time is greatly delayed at temperature below the operating temperature range. However,this does not mean the LCD will be out of the order. It will recover when it returns to the specified temperature range.(4) If the display area is pushed hard during operation, the display will become abnormal. However, itwill return to normal if it is turned off and then on.(5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit.Therefore, this product must be used and stored within the specified condition of 23±5°C, 45±20%RH.(6) When turning the power on, input each signal after the positive/negative voltage becomes stable.11.5 SAFETY(1) It is recommended to crush damaged or unnecessary LCDs into pieces and wash them off withsolvents such as acetone and ethanol, which should later be burned.(2) If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash offthoroughly with soap and water.12.

关于B类电气装置接地电阻值的讨论[1]

关于B类电气装置接地电阻值的讨论[1]

关于B类电气装置接地电阻值的讨论信息产业电子第十一设计研究院有限公司 杨天义摘要:依据等同采用IEC相关标准的新的国家标准,对原电力行业标准中的B类电气装置(建筑物电气装置)的保护接地电阻值,按照不同的高、低压系统接地形式下的安全性要求,提出了新的建议,并就其确定原则作出了说明。

关键词:B类电气装置 保护接地电阻 故障接触电压 工频应力电压电气装置的接地技术是关系到电气装置能否实现其功能性和安全性的基本技术之一,它包括电气装置的接地系统的设置,接地电阻值的确定、接地装置的安装、敷设、运行、检测和维护等诸多方面的技术。

原国家标准GBJ65-83《工业与民用电力装置的接地设计规范》颁布至今已逾二十多年,许多内容已落后于二十多年来接地技术的发展,现今供电力部门和设计单位遵循的电力行业标准DL/T621-1997《交流电气装置的接地》虽然既包括了对电力部门管理的发电、变电、送电和配电电气装置(简称为A类电气装置)的接地要求,也包括了由用户管理的“建筑物电气装置”(简称为B类电气装置)的接地要求,但仍有部分内容落后于当今科技的飞速发展,国内的一些资深电气专家已对此规范提出了许多很好的建议和意见[1],中国电工技术学会的“工业与建筑应用专委会”还专门为之举办了专题研讨会[2]。

这反映出了电工技术学界对这本基础性的国家标准技术规范的热切期盼,对此,笔者也不揣冒昧,借参与审定修编“工业与民用配电设计手册”之第十四章“接地”的机会,仅就有关建筑物电气装置(B类电气装置)的接地电阻值的问题提出一点不成熟的个人看法来参与讨论,目的旨在对将于2006年修订出版的新的国家标准“交流电气装置的接地”规范能有所裨益。

关于建筑物电气装置的接地问题,当前业界最为关注的是关于接地系统的设置,即是否采用“联合接地系统”(或者称为“共用接地系统”),另一个就是接地电阻的取值问题,对前一个问题,已有许多专家发表了许多很好的意见,本文不拟讨论,仅就后者,即建筑物电气装置的接地电阻值,对不同的高、低压系统接地形式,究竟取多少较为合适,发表一点个人的浅见。

PRECAUTIONS FOR USING LCD MODULES10.1. HANDLING PRECAUTIONS(1) The display panel is made of glass. Do not subject it to a mechanical shock or impact by droppingit.(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any inyour mouth. If the substance contacts your skin or clothes, wash it off using soap and water.(3) Do not apply excessive force to the display surface or the adjoining areas since this may cause thecolor tone to vary.(4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handlethis polarizer carefully.(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a softdry cloth. If it is heavily contaminated, moisten a cloth with one of the following solvents: - Isopropyl alcohol- Ethyl alcohol(6) Solvents other than those above mentioned may damage the polarizer.Especially, do not use the following:- Water- Ketone- Aromatic solvents(7) Extra care to minimize corrosion of the electrode. Water droplets, moisture condensation or acurrent flow in a high-humidity environment accelerates corrosion of the electrode.(8) Install the LCD Module by using the mounting holes. When mounting the LCD Module, makesure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/Ocable or the backlight cable.(9) Do not attempt to disassemble or process the LCD Module.(10) NC terminal should be open. Do not connect anything.(11) If the logic circuit power is off, do not apply the input signals.(12) To prevent destruction of the elements by static electricity, be careful to maintain an optimumwork environment.- Be sure to ground the body when handling he LCD Module.- Tools required for assembling, such as soldering irons, must be properly grounded.-To reduce the amount of static electricity generated, do not conduct assembling and other workunder dry conditions.-The LCD Module is coated with a film to protect the display surface. Exercise care when peeling off this protective film since static electricity may be generated.10.2. STORAGE CONDITIONSWhen storing, avoid the LCD module to be exposed to direct sunlight of fluorescent lamps. For stability, to keep it away form high temperature and high humidity environment (The best condition is : 23±5°C, 45±20%RH). ESD protection is necessary for long-term storage also.10.3. OTHERSLiquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subject to a low temperature.If the LCD Module have been operating for a long time showing the same display patterns the display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear.A normal operating status can be recovered by suspending use for some time. It should be noted that this phenomenon does not adversely affect performance reliability.To minimize the performance degradation of the LCD Module resulting from destruction caused by static electricity etc. exercise care to avoid holding the following sections when handling the modules.- Exposed area of the printed circuit board.- Terminal electrode sections.11. Using LCD modules11.1 LIQUID CRYSTAL DISPLAY MODULESLCD is composed of glass and polarizer. Pay attention to the following items when handling.(1) Please keep the temperature within specified range for use and storage. Polarization degradation,bubble generation or polarizer peel-off may occur with high temperature and high humidity.(2) Do not touch, push or rub the exposed polarizers with anything harder than a HB pencil lead (glass,tweezers, etc).(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers andreflectors made of organic substances, which will be damaged by chemicals such as acetone, toluene, toluene, ethanol and isopropyl alcohol.(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft materiallike chamois soaked in petroleum ether. Do not scrub hard to avoid damaging the display surface.(5) Wipe off saliva or water drops immediately, contact with water over a long period of time maycause deformation or color fading.(6) Avoid contacting oil and fats.(7) Condensation on the surface and contact with terminals due to cold will damage, stain orpolarizers. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air.(8) Do not put or attach anything on the display area to avoid leaving marks on.(9) Do not touch the display with bare hands. This will stain the display area and degrade insulationbetween terminals (some cosmetics are determinate to the polarizers).(10)As glass is fragile, it tends to become or chipped during handling especially on the edges. Pleaseavoid dropping or jarring.11.2 INSTALLING LCD MODULEAttend to the following items when installing the LCM.(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and thefitting plate should have enough height to avoid causing stress to the module surface, refer to the individual specifications for measurements. The measurement tolerance should be ±0.1mm.11.3 ELECTRO-STATIC DISCHARGE CONTROLSince this module uses a CMOS LSI, the same careful attention should be paid for electrostatic discharge as for an ordinary CMOS IC.(1) Make certain that you are grounded when handing LCM.(2) Before removing LCM from its packing case or incorporating it into a set, be sure the module andyour body have the same electric potential.(3) When soldering the terminal of LCM, make certain the AC power source for the soldering irondoes not leak.(4) When using an electric screwdriver to attach LCM, the screwdriver should be of groundpotentiality to minimize as much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of the motor.(5) As far as possible, make the electric potential of your work clothes and that of the workbenches tothe ground potential.(6) To reduce the generation of electro-static discharge, be careful that the air in the work is not toodried. A relative humidity of 50%-60% is recommended.11.4 PRECAUTIONS FOR OPERATION(1) Viewing angle varies with the change of liquid crystal driving voltage (Vo). Adjust Vo to showthe best contrast.(2) Driving the LCD in the voltage above the limit will shorten its lifetime.(3) Response time is greatly delayed at temperature below the operating temperature range. However,this does not mean the LCD will be out of the order. It will recover when it returns to the specified temperature range.(4) If the display area is pushed hard during operation, the display will become abnormal. However, itwill return to normal if it is turned off and then on.(5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit.Therefore, this product must be used and stored within the specified condition of 23±5°C, 45±20%RH.(6) When turning the power on, input each signal after the positive/negative voltage becomes stable.11.5 SAFETY(1) It is recommended to crush damaged or unnecessary LCDs into pieces and wash them off withsolvents such as acetone and ethanol, which should later be burned.(2) If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash offthoroughly with soap and water.12.

PRECAUTIONS FOR USING LCD MODULES10.1. HANDLING PRECAUTIONS(1) The display panel is made of glass. Do not subject it to a mechanical shock or impact by droppingit.(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any inyour mouth. If the substance contacts your skin or clothes, wash it off using soap and water.(3) Do not apply excessive force to the display surface or the adjoining areas since this may cause thecolor tone to vary.(4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handlethis polarizer carefully.(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a softdry cloth. If it is heavily contaminated, moisten a cloth with one of the following solvents: - Isopropyl alcohol- Ethyl alcohol(6) Solvents other than those above mentioned may damage the polarizer.Especially, do not use the following:- Water- Ketone- Aromatic solvents(7) Extra care to minimize corrosion of the electrode. Water droplets, moisture condensation or acurrent flow in a high-humidity environment accelerates corrosion of the electrode.(8) Install the LCD Module by using the mounting holes. When mounting the LCD Module, makesure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/Ocable or the backlight cable.(9) Do not attempt to disassemble or process the LCD Module.(10) NC terminal should be open. Do not connect anything.(11) If the logic circuit power is off, do not apply the input signals.(12) To prevent destruction of the elements by static electricity, be careful to maintain an optimumwork environment.- Be sure to ground the body when handling he LCD Module.- Tools required for assembling, such as soldering irons, must be properly grounded.-To reduce the amount of static electricity generated, do not conduct assembling and other workunder dry conditions.-The LCD Module is coated with a film to protect the display surface. Exercise care when peeling off this protective film since static electricity may be generated.10.2. STORAGE CONDITIONSWhen storing, avoid the LCD module to be exposed to direct sunlight of fluorescent lamps. For stability, to keep it away form high temperature and high humidity environment (The best condition is : 23±5°C, 45±20%RH). ESD protection is necessary for long-term storage also.10.3. OTHERSLiquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subject to a low temperature.If the LCD Module have been operating for a long time showing the same display patterns the display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear.A normal operating status can be recovered by suspending use for some time. It should be noted that this phenomenon does not adversely affect performance reliability.To minimize the performance degradation of the LCD Module resulting from destruction caused by static electricity etc. exercise care to avoid holding the following sections when handling the modules.- Exposed area of the printed circuit board.- Terminal electrode sections.11. Using LCD modules11.1 LIQUID CRYSTAL DISPLAY MODULESLCD is composed of glass and polarizer. Pay attention to the following items when handling.(1) Please keep the temperature within specified range for use and storage. Polarization degradation,bubble generation or polarizer peel-off may occur with high temperature and high humidity.(2) Do not touch, push or rub the exposed polarizers with anything harder than a HB pencil lead (glass,tweezers, etc).(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers andreflectors made of organic substances, which will be damaged by chemicals such as acetone, toluene, toluene, ethanol and isopropyl alcohol.(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft materiallike chamois soaked in petroleum ether. Do not scrub hard to avoid damaging the display surface.(5) Wipe off saliva or water drops immediately, contact with water over a long period of time maycause deformation or color fading.(6) Avoid contacting oil and fats.(7) Condensation on the surface and contact with terminals due to cold will damage, stain orpolarizers. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air.(8) Do not put or attach anything on the display area to avoid leaving marks on.(9) Do not touch the display with bare hands. This will stain the display area and degrade insulationbetween terminals (some cosmetics are determinate to the polarizers).(10)As glass is fragile, it tends to become or chipped during handling especially on the edges. Pleaseavoid dropping or jarring.11.2 INSTALLING LCD MODULEAttend to the following items when installing the LCM.(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and thefitting plate should have enough height to avoid causing stress to the module surface, refer to the individual specifications for measurements. The measurement tolerance should be ±0.1mm.11.3 ELECTRO-STATIC DISCHARGE CONTROLSince this module uses a CMOS LSI, the same careful attention should be paid for electrostatic discharge as for an ordinary CMOS IC.(1) Make certain that you are grounded when handing LCM.(2) Before removing LCM from its packing case or incorporating it into a set, be sure the module andyour body have the same electric potential.(3) When soldering the terminal of LCM, make certain the AC power source for the soldering irondoes not leak.(4) When using an electric screwdriver to attach LCM, the screwdriver should be of groundpotentiality to minimize as much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of the motor.(5) As far as possible, make the electric potential of your work clothes and that of the workbenches tothe ground potential.(6) To reduce the generation of electro-static discharge, be careful that the air in the work is not toodried. A relative humidity of 50%-60% is recommended.11.4 PRECAUTIONS FOR OPERATION(1) Viewing angle varies with the change of liquid crystal driving voltage (Vo). Adjust Vo to showthe best contrast.(2) Driving the LCD in the voltage above the limit will shorten its lifetime.(3) Response time is greatly delayed at temperature below the operating temperature range. However,this does not mean the LCD will be out of the order. It will recover when it returns to the specified temperature range.(4) If the display area is pushed hard during operation, the display will become abnormal. However, itwill return to normal if it is turned off and then on.(5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit.Therefore, this product must be used and stored within the specified condition of 23±5°C, 45±20%RH.(6) When turning the power on, input each signal after the positive/negative voltage becomes stable.11.5 SAFETY(1) It is recommended to crush damaged or unnecessary LCDs into pieces and wash them off withsolvents such as acetone and ethanol, which should later be burned.(2) If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash offthoroughly with soap and water.12.
