Dry type transformer temperature control box BWD-3KR

The temperature controller for dry-type transformers is an intelligent controller designed specifically for the safe operation of dry-type transformers. The temperature controller adopts microcontroller technology and uses the platinum thermistor embedded in the dry-type transformer winding to detect and display the temperature rise of the transformer winding. It can automatically start and stop the cooling fan to force air cooling of the winding, avoiding or reducing faults caused by high temperature in the transformer. It can also control the output of over temperature alarm and over temperature trip to ensure that the transformer operates in a safe state, thereby extending the working life of the transformer.

Three phase circuit display/maximum value display; Fan automatic/manual start stop; Over temperature alarm; Overtemperature trip; Fault alarm; Black box function;
Fan timing excitation function; Simulation testing function; Digital compensation function; Cabinet door opening alarm function.

main features
Using LED displays makes the display of the working status and measured values of the temperature controller more intuitive.
I2C adjustment and storage technology is adopted to achieve power-off data protection storage.
The fan can be manually/automatically controlled to start and stop.
