The principle and measurement method of winding thermometer

In the process of the running of the transformer, the effect of winding thermometer is carried out on the coil winding temperature monitoring. The temperature of the winding will determine the service life of the transformer. The temperature of the insulating material will be affected by the winding temperature and aging conditions, especially the hottest temperature coil winding. General transformer winding potential is quite high, direct use of temperature measuring element will not be able to measure the temperature of the winding, in this case, adopt the indirect measuring method. The working principle of winding thermometer. Transformer load loss in the process of work happen, it will cause fever, transformer winding heat and transformer winding current is proportional to the. Transformer winding is insulation wrapped around, and the temperature of transformer oil zhongtong secondary current of the temperature of the electric heating element additive can measure out the temperature of the winding transformer. Winding thermometer works inside the oil hole is located in the transformer oil tank top package insert the thermometer sensor temperature, winding in transformer are not eligible to have no the phenomenon of fever, thermometer thermometer is shown in the transformer oil temperature. If the transformer in the operation of the load, current transformer output current for the pig matcher will through the electric heating element, electric heating element will be hot.
