Product Detail
The dry type transformer temperature controller BWD-3KR is a new generation multifunctional temperature controller designed for reliable operation of air-cooled dry type power transformers. Using three Pt100 platinum thermistors embedded in the three-phase winding package of the dry type power transformer to detect the temperature rise of the dry type power transformer package, and automatically controlling the start and stop of the cooling fan, overheating alarm, and ultra-high temperature trip based on the temperature rise to ensure the safe operation of the dry type power transformer. Designed according to the JB/T7631-2016 standard, the temperature controller has the characteristics of simple structure, reliable operation, and strong anti-interference ability. At the same time, the temperature controller also has a "black box" function, which can record the temperature of the three windings before the power failure of the temperature controller. Equipped with RS485 communication function, it can remotely transmit three-phase temperature and operating status
