Temperature control instrument for dry transformer

The utility model discloses a temperature controller of a dry type transformer, which comprises a temperature detecting unit and a control unit, wherein the control unit comprises a temperature signal processing unit, a main controller and a radiating unit for radiating the heat of the dry type transformer which are connected in turn. The temperature detecting unit is connected with the input end of the temperature signal processing unit in the control unit, the temperature signal processing unit can send signals which are obtained by conducting the signal processing for the temperature data collected by the temperature detecting unit into the master controller, and master controller is used to determine whether to start the radiating unit to radiate the heat of the dry type transformer. The temperature controller can provide the appropriate temperature operating environment for the dry type transformer, and effectively increases the service life and power supply reliability of the dry type transformer.
