特高压绝缘子检测机器人零值检测方案
特高压绝缘子检测机器人零值检测方案绝缘子运行中因雷击、机械负载和高电压的长期共同作用，会引起劣化。
导致其击穿电压不断下降。
当它下降到小于爬行干闪电压时，就称为低值绝缘子。
内部击穿电压为零时，称为零值绝缘子。
当绝缘子串中有低值或零值绝缘子时，在肮脏的环境中，在过电压甚至工作电压的作用下，容易发生闪络事故。
绝缘电阻合格的标准：(1)500Kv及以上电压等级绝缘子的绝缘电阻应大于或等于500M Ω。
(2)500Kv以下电压等级输电线路绝缘子的绝缘电阻应大于或等于300MΩ。
造成绝缘子劣化的原因有很多，主要有以下几个方面：(1)温度的影响，温度对绝缘电阻影响很大，绝缘电阻随温度上升而减小。
原因是温度升高，绝缘介质的极化加剧，电导增加使绝缘电阻下降，变化的原因与温度变化程度和绝缘材料的性质、结构等有关。
(2)湿度的影响，湿度对表面泄漏电流的影响较大，原因是绝缘表面吸附潮气，形成水膜，会使绝缘电阻明显下降。
(3)绝缘子机械过载造成的劣化。
(4)瓷件吸湿性劣化。
(5)瓷件内外应力重叠性劣化。
(6)瓷绝缘子热膨胀造成的劣化。
(7)钢帽浇装水泥饱和膨胀性劣化。
(8)钢帽浇装水泥冻结膨胀性劣化。
(9)钢帽、钢脚电腐蚀性劣化。
(10)绝缘子过电压造成的劣化。
(11)绝缘子内部缺陷造成的劣化。
绝缘子的检测分为在线检测：观察法、紫外成像法、超声波检测法、以非电量检测为代表的红外测温，以及以绝缘电阻、电场测量、脉冲电流法和漏电流法为代表的典型的电量检测两种。
(1)直接观测法常见的表面缺陷，如护套、伞裙、金具等部位有无开裂，有无电蚀损、粉化、漏电痕迹等，如有以上现象应立即更换绝缘子。
但地面观察不够可靠，还需登塔检测而且难以发现绝缘子内故障，如树枝状通道等。
(2)绝缘子电阻测定法良好绝缘子的绝缘电阻，一般在数千兆欧以上，劣质绝缘子，其表现为绝缘电阻降低、甚至为零。
该方法可停电、也可带电测量，属接触式。
该方法是目前最为直接可靠的检测方法。

(16)BATTERY & FUSE REPLACEMENT (16)SERVICE INFORMATION (17)SAFETY RULESThe meter has been designed with safety in mind. However, no design can completely protect against incorrect use. Electrical circuits are dangerous and lethal through lack of caution or poor safety practice. The following rules should reduce the danger:• Read the User's manual carefully and completely before using the instrument. Fully understand the instructions before using this product. Follow the instructions for every test. Take all the necessary precautions. Do not exceed the limits of this instrument.• The circuit to be tested must be de-energized and isolated before connections are made to it.• Do not use test leads, probes or crocodiles/alligatorsclips that are dirty, damaged or have broken or cracked insulation. Such accessories should be removed and repaired Immediately.• Always disconnect the test leads before replacing any fuse Always replace the fuse with the type specified and ensure that they are correctly fitted.• Double check the switch settings and leads connections before measuring. Make a sketch to ensure proper operation and principle of measurement is correct and well understood.• Do not touch any exposed wiring, connections or other "live" parts of an electrical circuit. If in doubt, check the circuit first for voltage before touching it.• This instrument should only be used by a competent, suitably trained person which understand fully this test & measurement procedure.Warning, risk of electric shock.GENERAL DESCRIPTIONThe meter digital milli-ohmmeter is a battery operated instrument which supply a low current to the circuit under test, with which, stable, accurate measurement of low resistance can be made, still, over a wide range of values.Resolution on the lowest range is 100µΩ and on the highest range, 1Ω.The meter has 5 measuring ranges, from 200.0mΩ to 2000Ω. Measurements are displayed on a 3½ digit custom liquid crystal display with large digits.This instrument is powered from batteries only.It has a regulated DC constant current source with current of1mA 10mA and 100mA.The instrument supply that current to the resistance being measured through the C1 and C2 terminals (C1 being +, C2 being -). The voltage drop across the resistance under test is measured by the potential terminals P1 and P2 (P1 being +, P2 being -). Should the current regulation drop out, the R C LED will lit, indicating that the resistance in the current circuit is too high. (Lowering the current by selecting a higher resistance range can solve the regulation.)Should the R P LED lit, that mean that the voltage measured on the resistance is too high, and therefore over-range.The resistance is measured precisely when the R P and R C LEDs do not lit. If anyone of these LEDs lit, then the measurement can be inaccurate.can be viewed in most lightning conditions. This display indicates the differences conditions (Hold, m, buzzer, polarity condition of load, + or -, automatic decimal point change).The ranges are selected by a 5 position rotary switch, and a test is initiated by pressing the ON push-button.The instrument takes measurements for 10 seconds if the "ON" "TEST r e" presentative" button is depressed for less than 2 seconds. If the same push button is pressed for more than 3 seconds, the test will carry on for 60 seconds.The tester switch "OFF" completely when the rotary switch is in the "OFF" position.The tester "Hold" the last reading before stopping the test.The tester is fuse protected and has a crowbar between C1 and C2.This crowbar is activated by voltage. If the voltage is too high, that crowbar will blow the fuse automatically to interrupt the circuit.The voltage between P1 and P2 is also protected for over voltage but does not have a fuse.The tester has a temperature shut down. The temperature sensing is done on the current regulation transistor.Should this over-temperature let lit, allow the instrument to cool down for a while before proceeding further.FRONT PANEL LAYOUTIf NO TEST LED lit, the current source is stopped.Over Temperature indicator. Lit = Over-temperature or Array test stopped.Resistance between the current leads too high (fuse!).Resistance between the potential leads too high.Meet LVD & EMCRotary Selector Switch requirementsPREPARATION FOR USEWhen unpacked, the tester should be inspected for any visible signs of damage, and the preliminary checks described in the user's manual should be performed to ensure that it is operating correctly. If there is any sign of damage, or if the instrument does not operate correctly, return it to your nearest supplier. PRELIMINARY CHECKSCheck the battery• If the battery symbol is shown on the LCD, then replace with new batteries before proceeding.Check the current regulation:• Connect the current leads to C1 and C2.• Select a range, and short the current test leads. The R C LED should go off, indicating that the current regulation is ok. Check the voltage measurement:• Connect the potential leads to P1 and P2.• Short the P1 and P2. The display should indicate 0000.• Remove the short from P1 and P2 and C1 and C2. Touching the potential test leads P1 to C1 and P2 to C2, the R P LED should lit, indicating an over-voltage or over-range.This proving test can be repeated on all the ranges if need be. You can also check the polarity indication of the milli-voltmeter by touching the potential test leads P1 to C2 and P2 to C1, the R P LED should lit, indicating an over-voltage or over-range. The - indicator should be indicating - on the LCD, showing the polarity change.Total check can be done by shorting all the test leads together C1, C2, P1, P2. The display should indicate close to 0000 (depending of the crocodiles clips used and how they are shorted). Both R C and R P LED should be OFF, indicating thatPRECAUTIONS• Always ensure that the circuit to be measured is switched "OFF", isolated and completely de-energized before connecting the test Leads.• If it is probable that the instrument's protection has been impaired due to electrical, mechanical or environmental damage, it must not be used. It should be returned to your nearest distributor or agent for checking and repair.• To prevent damage to the liquid crystal display, the minimum storage temperature of -20°C must be observed. It should also be noted that below 0°C the operation of the LCD will be sluggish.• If the exterior of the instrument requires cleaning, it should be done with a sponge and a mild solution of detergent and water.• Other mechanical cleaning agents must not be used.MEASURING• Perform the preliminary checks before proceeding with measurement and ensure that the precautions listed are observed.• Connect the test leads (color coded) to the instrument as shown.• The current test leads must always be outside of the potential test leads.• Please note that the shorter the potential test leads, the better long potential test leads will pick up noise.• Screened test leads are recommended for better environmental noise rejection.SIMPLIFIED MEASUREMENTThe 4 wires measurement has many advantages. The errors due to the resistance of the test leads and the contacts aswell as R A and R B are eliminated. However, in some cases, for example when using the high resistance range (2000Ω) the four wires method is not necessary to still have a good percentage of accuracy (compared to the full scale). The simplified method of two wires can be used without too much problems. C1 and P1 can be shorted as well as C2 and P2.APPLICATIONSThe meter Digital milli-ohmmeter, with its measuring range of 100µΩ to 2000Ω, is suitable for a wide range of applications such as:• Measuring the winding resistance of electric motors, generators and transformers.• Bond testing in mines, aircraft, railways, ships, domestic and industrial wiring installations.• Measuring the ring main continuity testing in industrial and domestic wiring installations.• Measuring resistance in electronic equipment such as shunts, pcb tracks, switch and relay resistance.• Checking compression joints on overheads lines.• Testing and maintenance of switchboard /sub-station equipment on such items as fuses, joints, contacts and bonds.TEST LEADSThe test leads supplied with the instrument are suitable forconnecting to conductors up to 17mm in diameter or bus bars17mm tick. There will be, instances where the item beingmeasured require larger jaws, and the user is advised to makeup his own leads. There will be occasions when longer leadsare required due to the geometry of the item being tested. Someguidance notes should assist in the assembly of such leads: Length of the potential leads should be as short as possible. Insulated 16/0.2mm, tinned copper wire is recommended. The two potential leads should have the samelength to minimize inaccuracies due to unbalance. SUPPLIED POTENTIAL TEST LEADSP1+ test lead is of Red color, shrouded, 4mm safety plug whichat one end have a crocodile (alligator) clip for connection to theresistance to be measured. The other end plugs into the meter(4mm shrouded) color coded sockets.P2- test lead is of Blue color, shrouded, 4mm safety plug whichat one end have a crocodile (alligator) clip for connection to theresistance to be measured. The other end plugs into the meter(4mm shrouded) color coded sockets.SUPPLIED CURRENT TEST LEADSC1+ test lead is of Green color, shrouded, 4mm safety plugwhich at one end have a crocodile (alligator) clip for connectionto the resistance to be measured. The other end plugs into themeter (4mm shrouded) color coded sockets.C2- test lead is of Black color, shrouded, 4mm safety plug whichat one end have a crocodile (alligator) clip for connection to theresistance to be measured. The other end plugs into the meterTHERMAL EFFECTSTemperature can have a significant effect on the performance of a digital milli-ohmmeter due to the temperature coefficient of the resistance under test and thermal EMF's across the dissimilar conductors.Most conductors have a large temperature coefficient of resistance.For example: 0.4%/°C for copper. A copper conductor that has a resistance of 10.00mΩ at 20°C will increase to 10.40mΩ at 30°C. This change should be taken into account when making measurements.A current going through a resistance will also elevate its temperature. So duration of the test can change the resistance. When measuring the resistance of item, such as current shunts, which have joints of dissimilar conductors, thermal EMF can affect the accuracy of the measurement. This condition canbe detected if the reading alters when the leads are reversed. To compensate for this effect, the average of the two readings should be taken as the true measurement.FUSES REPLACEMENTThere are three fuses:• Power Supply FuseThe power supply fuse is situated under the tester. Open the battery compartment and replace the fuse with the same type (0.5A / 250Vac, 5 x 20mm)• Current Circuit FuseFuse protection is provided on the current terminals.This fuse is situated under the Printed Circuit Board. To access it, you need to unscrew the four mounting screwslocated under the foots, and the two others are located inside the battery compartment.The fuse is automatically blow by the crowbar, should voltage be present on the resistance under test. This is to prevent damage to the instrument.It is indicative of this fuse being blown is the R C LED stays "on". (0.5A / 250Vac, 5 x 20mm)• Potential Circuit FuseFuse protection is provided on the potential terminals.This fuse is situated under the Printed Circuit Board. To access it, you need to unscrew the four mounting screws which are holding the font panel. Two of these screws are located under the foots, and the two others are located inside the battery compartment.The fuse is automatically blow by the crowbar, should voltage be present on the resistance under test. This is to prevent damage to the instrument.If the preliminary tests does not lit R P this is indicative of this fuse being blown. (0.5A / 250Vac, 5 x 20mm)INPUT LIMITS & PROTECTIONSThe maximum continuous voltage which can be applied across the potential and current leads is around 10.7V. Applying more than that voltage will automatically blow their respective fuses. However, the crowbar trigger can be factory adjusted for your application.We have specially selected that method to stop damaging the instrument, should it be misused.SPECIFICATIONSMeasuring Ranges0-200.0mΩ in steps of 100µΩ0-2000mΩ in steps of 1mΩ0-20.00Ω in steps of 10mΩ0-200.0Ω in steps of 100mΩ0-2000Ω in steps of 1ΩAccuracy±0.5% of reading ±2 digits over theOperating temperature range, -15°Cto +55°C, with the supplied test leads.
