Product details
Bwdk type temperature controller for dry-type transformer is an intelligent instrument composed of microprocessor. It uses 3-5 PT100 platinum resistances as temperature sensors, and puts three platinum resistances into the three-phase winding of transformer respectively. When the temperature of transformer changes, the resistance of platinum resistance changes synchronously with the temperature. The temperature controller can monitor the set temperature value. It can start and stop the cooling fan, send out fault alarm, over temperature alarm, over temperature trip and other signals to protect the transformer.
