热电偶和热电阻手册

热电偶和热电阻技术手册作者：天长市金德仪表有限公司网址：/热电偶测量温度时要求其冷端(测量端为热端，通过引线与测量电路连接的端称为冷端)的温度保持不变，其热电势大小才与测量温度呈一定的比例关系。

若测量时，冷端的(环境)温度变化，将影响严重测量的准确性。

在冷端采取一定措施补偿由于冷端温度变化造成的影响称为热电偶的冷端补偿。

热电偶的冷端补偿通常采用在冷端串联一个由热电阻构成的电桥。

电桥的三个桥臂为标准电阻，另外有一个桥臂由(铜)热电阻构成。

当冷端温度变化(比如升高)，热电偶产生的热电势也将变化(减小)，而此时串联电桥中的热电阻阻值也将变化并使电桥两端的电压也发生变化(升高)。

如果参数选择得好且接线正确，电桥产生的电压正好与热电势随温度变化而变化的量相等，整个热电偶测量回路的总输出电压(电势)正好真实反映了所测量的温度值。

这就是热电偶的冷端补偿原理。

热电阻热电阻是中低温区最常用的一种温度检测器。

它的主要特点是测量精度高，性能稳定。

其中铂热是阻的测量精确度是最高的，它不仅广泛应用于工业测温，而且被制成标准的基准仪。

1、热电阻测温原理及材料热电阻测温是基于金属导体的电阻值随温度的增加而增加这一特性来进行温度测量的。

热电阻大都由纯金属材料制成，目前应用最多的是铂和铜，此外，现在已开始采用镍、锰和锗等材料制造热电阻。

2、热电阻的类型1)普通型热电阻从热电阻的测温原理可知，被测温度的变化是直接通过热电阻阻值的变化来测量的，因此，热电阻体的引出线等各种导线电阻的变化会给温度测量带来影响。

2)恺装热电阻恺装热电阻是由感温元件(电阻体)、引线、绝缘材料、不锈钢套管组合而成的坚实体，它的外径一般为(p2--cp8mm,最小可达cpmm。

与普通型热电阻相比，它有下列优点:①体积小，内部无空气隙，热惯性上，测量滞后小;②机械性能好、耐振，抗冲击;③能弯曲，便于安装④使用寿命长。

3)端面热电阻端面热电阻感温元件由特殊处理的电阻丝材绕制，紧贴在温度计端面。

High voltage circuit breaker is the most important control and protection equipment in power system. Northern winter weather is cold, and the breaker mechanism box relies on the heating device to raise the temperature, thus ensure the normal operation of the circuit breaker. Now the heating plate of the 100W aluminum alloy is adopted, it is easy to damage, therefore, how to improve the electric heating plate has become an urgent problem to be solved. Under the premise of the original appearance, the internal heat radiating element is changed into a drawer type electrothermal film module of silicon rubber. The outer package of the module is provided with a concave aluminum envelope, its bottom is equipped with a pilot lamp for working status indicator, this module can be used as long as it is inserted into the groove of the original heating plate, the service life is long, and the replacement is convenient.IntroductionHigh voltage circuit breaker is the most important control and protection equipment in power system. Control action is according to the power grid operation need, can safely and reliably input or withdraw from the corresponding line or electrical equipment, safety action is in the line or electrical equipment failure, can quickly remove the fault part from the power grid, to protect the normal operation of the power grid fault free part. High voltage transmission and distribution lines require high voltage circuit breakers with automatic switching function, to ensure the normal operation of the power grid. In short, it is required to be able to reliably switch to the circuit in accordance with the needs of normal or accident. The functions of high voltage circuit breakers are as follows:(1) It should be a good conductor in the closed state, not only to the normal current should be able to withstand its thermal and mechanical action, but also to the short-circuit current should be so.(2) It has good insulating properties between the ground, the interphase and the fracture surface.(3)At any point in the closed state, it should be able to open the current below the rated current ina short period of time without the risk of the occurrence of the voltage.(4) At any point in the open state, it should be able to close the current in the short circuit safely without the contact melting welding [1].The Components of the Circuit BreakerConductive part.The conductive part is the path of the current, is usually made of conductive rod, isolator gate, beam, flexible connection , contact terminal etc. The contact is the most important part of the conductive part, the circuit breaker is to rely on him to connect or disconnect the current.Due to operation of the circuit breakers in the long run pass through the over load current, the conductive loop generates heat, when the contact resistance is large contact, heating will be more powerful, even burn out.Arc extinguishing device.The arc extinguishing device of the circuit breaker is the heart of the circuit breaker. Because the contact can only cut off the current, and the arc extinguishing device can extinguish the arc which isgenerated by the contact in the off current. Therefore, its good and bad determines the breaking capacity of circuit breakers to a great extent.Insulation system.The following three aspects must be guaranteed in the circuit breaker.(1) The insulation between the charged part and the ground part, mainly the porcelain bushing, the lifting rod, etc.(2) When the circuit breaker is in the open position, the insulation between the fracture surface is usually guaranteed by insulation oil (vacuum or SF6)(3) The insulation of the phase, three-phase oil circuit breaker mainly rely on insulation oil, insulation separator to insulation.Operating mechanism.The operation mechanism is an important part of the circuit breaker, it can ensure that the contact system in a certain way and a certain speed when divide-shut brake, reliable connection and disconnection of the circuit, The operation of mechanical oil is manual, electromagnetic, spring type. Require him to move flexible and reliable. It requires action flexible and reliable[1].Heating device.A heating device is arranged in a circuit breaker mechanism box, it can raise the temperature in the box to ensure the normal operation of the circuit breaker.The Shortage of Heating DeviceNorthern winter weather is cold, the breaker mechanism box needs to rely on the heating device to raise the temperature in the chamber to ensure the normal operation of the circuit breaker. 100W aluminum alloy plate heater is used in all circuit breakers in Fushun area, The type heating plate adopts a resistance wire inside, the 220V voltage is set up on both ends to cause the resistance wire to heat and it increases the temperature in the mechanism box, but the heat could not be distributed which leads to the resistance wire breakage, damage to the heating system.The Design Principle of the Drawer Type Circuit Breaker Heating DeviceAiming at the problems in the existing technology, based on the excellent properties of silicone rubber electric heating module, and through the heating effect comparison，the article provides a drawer type heating device for 66kV and the above breaker mechanism, which solves the problem of the damage of the heating device in the prior art.The design scheme is as follows:Under the premise of the original appearance, the inner heat radiating element is replaced into a drawer type silicon rubber electrothermal film module, This module uses silicone rubber which has high temperature (-60℃to 250℃), high thermal conductivity (thermal conductivity coefficient of 0.83), good insulation performance ,good strength, high temperature resistant fiber reinforced material and soft electric heating membrane element which is composed of nickel chromium alloy resistance wire or circuit with metal foil heating film, the outer package of the module is provided with a concave aluminum envelope, its bottom is equipped with a pilot lamp for working status indicator, drawer type silicon rubber electrothermal module is inserted into the groove of the original heating plate.Fig.1.

measurement of semiconductors. Table 1 summarizes the specifications of these two types of thermocouples. Although Type T has a small tolerance, its positive electrode has a high thermal conductivity. Therefore, the thermocouple may serve as a heat sink, decreasing the measured temperature below the actual temperature. Thus, it is considered that thermocouples of Class 1 Type K are ideal for the thermal measurement.
The third point is regarding tip treatment of thermocouples. The simplest method is to twist the tip several times to make it a twisted wire as shown in Figure 2. Nevertheless, since the temperature is measured at the first contact point in this method, the remaining section is unnecessary and may cause undesirable heat radiation. However, since cutting off the remaining section compromises the contact, the temperature becomes unstable.

If cable selected is longer than the pipe, spiral it evenly along the entire pipe.P i p e d i a m e t e r (i n )211/2P i p e d i a m e t e r (i n )211/2Pipe length (ft)Pipe length (ft)Electrical codesArticles 422 and 427 of the National Electrical Code (NEC), and Part 1, Section 62 of the Canadian Electrical Code (CEC), govern the installation of FrostGuard heating cable for pipe freeze pro-tection and must be followed.Important: For the nVent warranty to be valid, you must comply with all the requirements outlined in these guidelines.All thermal and design information provided here is based upon a “standard” installation with heating cable fastened to an insu -lated pipe. For any other application or method of installation, consult nVent at (800) 545-6258 | 3Heating cable installation1. Prepare for installation.• Store the heating cable in a clean, dry place. • Complete piping pressure test. • P rior to installing the cable, remove any sharp surfaces onthe pipe that might damage the heating cable. • R eview the FrostGuard heating cable design and compareto materials received to verify that you have the proper FrostGuard heating cable. • W alk the system and plan the routing of the FrostGuardheating cable on the pipe.2. Position and attach heating cable to pipe. • Be sure all piping to be traced is dry. • I nstall heating cable, using straight tracing Figure 1, or spiraling Figure 2. • F or straight tracing, install the heating cable on a lower half of the pipe; for example, in the 4 o’clock or 8 o’clock position.• B e sure to install the additional heating cable required for valves, flanges, etc. as shown in Figures 1 and 2.• W hen the design calls for spiraling, begin by suspending a loop every 10 feet as shown in Figure 2. To determine the loop length, divide the FrostGuard length by your pipe length and multiply by 10. For example, if you are using a 50 ft FrostGuard on a 40 foot pipe, leave a 12-foot loop of heating cable at every 10-foot section of pipe. Grasp the loop in its center and wrap it around the pipe. Even out the distance between spirals by sliding the wraps along the pipe. Use glass tape to secure the center of the loop to the pipe. • F asten FrostGuard heating cable to the pipe at 1-footintervals using H903 fiberglass application tape or nylon cable ties. Do not use vinyl electrical tape, duct tape, metal bands, or wire. • I f excess cable remains at the end of the pipe, double itback along the pipe.3. Check the installation.• P rior to installing thermal insulation, make sure the heating cable is free of mechanical damage (from cuts, clamps, etc.) and thermal damage (from solder, overheating, etc.).4. Install thermal insulation.• A reliable FrostGuard system depends on properly installed and dry, weatherproofed thermal insulation.• E nsure that at least 1/2” of preformed foam or equivalentthermal insulation is used and that all piping, includingvalves, joints, and wall penetrations, has been fully insu-lated as shown in Figure 3.• For protection to -20°F (-29°C), use 1” thick insulation.• I nstall the insulation on the piping as soon as possible tominimize the potential for mechanical damage after instal-lation.• B e sure the FrostGuard 120 V label is visible on the outside of the thermal insulation.5. Finishing the installation.• T o prevent damage to the heating cable or cord, secure the power cord (cold lead) with a plastic cable tie, glass clothtape, or duct tape as shown in Figure 4.• T wo labels indicating the presence of electric pipe heating cable are included with the heating cable. Attach the two“Electric Traced” labels on the outer surface of the pipeinsulation at suitable intervals to indicate the presence ofFrostGuard electric heating cable.6. Starting the system.• n Vent recommends that the system be tested per the“Cable testing and maintenance” section below.• P lug the heating cable into a 120-V ground-fault protectedoutlet.• Check the circuit breaker to verify power to the cable.• Standing water in the pipe should feel warm within an hour.Cable testing and maintenanceUsing a 2500-Vdc megohmmeter, check the insulation resis-tance between both of the rectangular (power) prongs on the plug and the round (ground) prong after installing the heating cable. Minimum reading should be 1000 megohms.Record the original values for each circuit, and compare subse-quent readings taken during regular maintenance schedules to the original values.If the readings fall below 1000 megohms, replace the FrostGuard cable with a new unit. Do not attempt to repair the unit.WARNING: Fire and Shock Hazard.Damaged heating cable can cause electrical shock, arcing, and fire. Do not attempt to repair or energize damaged heating cable. Remove it at once and replace with a new length.4 | | 5 General requirements for roof & gutter de-icing:• F rostGuard is designed to remove melt water, not accumu-lated snow.• F rostGuard heating cable will not keep snow or ice from fall-ing off the roof. Snow fences or snow guards should be usedto eliminate snow movement. For the names of manufactur-ers of snow guards or snow fences, contact nVentat (800) 545-6258.• FrostGuard heating cables may be used on:- R oofs made from all types of standard roofing materials,including shake, shingle, rubber, tar, wood, metal,and plastic.- G utters made from standard materials, including metal andplastic.- D ownspouts made from standard materials, including metaland plastic.• Do not use an extension cord.• D o not install the heating cable underneath any roof coveringfor roof and gutter de-icing.• I nstall only in accessible locations; do not install behind wallsor where the cable would be hidden.• Do not run the heating cable through walls, ceilings, or floors.• C onnect only to ground-fault protected outlets that have beeninstalled in accordance with all prevailing national and localcodes and standards and are protected from rain and otherwater.Electrical codesArticle 426 of the National Electrical Code (NEC), and Part 1,Section 62 of the Canadian Electrical Code (CEC), govern theinstallation of FrostGuard heating cables for roof and gutter de-icing and must be followed.Important: For the nVent warranty to be valid, you must complywith all the r equirements outlined in these guidelines.All design information provided here is based on a “standard”shake or shingle roof application.

Position and attach the heating cable on roofs.•Loop the heating cable on the overhang area of the roof. This is the part that extends past the building wall. Extend thebottom of each heating cable loop over the roof edge and,using a UV-resistant cable tie, connect the bottom of eachloop to the cable running in the gutter to ensure a drainagechannel off the roof and into the gutter and downspout. The cable running in the gutter should remain against the bottom of the gutter as shown in Figures 5 and 6.Standing Seam Metal Roof**Eave overhang(in)Standing SeamSpacing (in)Tracing heights(in)Feet of FrostGuardper foot of roof edge None*1818 2.5121824 2.8241836 3.6361848 4.3None*2418 2.0122424 2.4242436 2.9362448 3.6*Gutter required**N o additional heating cable is required for gutters when tracing standing seam metal roofs6 | before installing heating cable in the clips.• A barrier (snow fence) can be placed on the roof abovethe heating cable. This prevents damage to the cable andkeeps the installation from coming loose due to ice slides.The heating cable can be attached to the barrier withUV-resistant cable ties, instead of using roof clips, if desired.Do not use wire or other materials because they maydamage the heating cable.In gutters and downspouts• Run heating cable along gutters and into downspouts, ending below the freezing level. Permanent attachment of the cable to the gutter bottom is not necessary. Loop the heating cable in downspouts. Do not leave the end of the FrostGuard in air at the end of the downspout as shown in Figure 10.• Use H915 Hanger Brackets at the gutter/downspout transitionto protect the heating cable from fraying and from damage from sharp edges and to provide strain relief as shown in Figure 11.Refer to the H915 kit instructions for installation details.• Route and secure cable to avoid possible mechanicaldamage, such as from ladders, etc. 3. Mark the installation.Two labels indicating the presence of electric de-icing and snow-melting equipment on the premises are included with the heating cable. One label must be posted at the electrical outlet cover. The other label must be posted at the fuse or circuit breaker panel. The labels must be clearly visible.4. Check the installation.• Prior to plugging in, check to be sure the heating cable isfree of mechanical damage (cuts, clamps, etc.).• Using a megohmmeter, test each circuit according to theinstructions in the “Heating cable testing and maintenance”section on next page.5.
