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.
