For an electrical equipment, its safety is the first premise that must be considered in production and use, and it is no exception for the baoding dry type transformer. The safe operation and service life of baoding dry transformer is largely determined by the safety and reliability of transformer windings. Winding temperature more than insulation resistance temperature insulation damage, baoding dry type transformer is not working, one of the main reasons for the operating temperature of the dry type transformer monitoring and alarm control is very important. The following is a brief introduction to the temperature control system of the guaranteed dry type transformer.
(1) automatic control of the fan: the temperature signal is measured by the Pt100 thermosensitive temperature measurement at the hottest part of the low voltage windings. Transformer load increases, the operating temperature rise, when the winding temperature of 110 ℃, the system automatically start the fan cooling; When the winding temperature as low as 90 ℃, the system automatically stop the fan.
(2) the temperature display system: through embedded in baoding dry type transformer low voltage winding of Pt100 thermistor measured temperature value, direct display of each phase winding temperature (three-phase, according to the inspection and the maximum value and can record the highest temperature), the highest temperature can be in 4 ~ 20 ma analog output, if need to transport to the distance (distance of up to 1200 m) computer, can be added with computer interface, one transmitter, maximum 31 sets of transformer monitoring at the same time. The overtemperature alarm and tripping of the system can also be activated by Pt100 thermistor signals to further improve the reliability of the temperature control system.
(3) overtemperature alarm and tripping: the PTC non-linear thermosensitive temperature signal in the low voltage winding is collected by the PTC in the low-voltage windings. When the transformer winding temperature continues to rise, if reaches 155 ℃, the system output overtemperature alarm signal; If the temperature continues to rise up to 170 ℃, the transformer can not continue to run, to the secondary transport overtemperature protection circuit tripping signals, should make transformer tripping rapidly.
