Dry-Type Transformer Thermostat

BWDK series uses three Pt100 platinum thermistors embedded in the threephase winding package of dry-type transformer to measure the temperature rise
of package, and controls according to the temperature rise the start and stop of
cooling fans, alarm in overtemperature until tripping under ultra-high temperature
automatically to ensure the safe operation of dry-type transformer. Due to the
use of the most advanced STMicroelectronics microcontroller combined with
the best IC storage and adjustment technology, the thermostat is designed
according to JB/T7631 and has the characteristics of simple structure, reliable
operation, strong anti-interference. At the same time, the thermostat works also
with function of "black box", which can record the temperature of three winding
packages and the working state of the machine before power failure.
