Abstract (en)

[origin: EP3893255A1] A heat exchange control system of a transformer, comprising a plurality of fans adapted to force the passage of air through one or more transformer windings in order to facilitate the heat exchange between such windings and the surrounding environment, actuation devices of said fans,one or more inputs for receiving the thermal status of the transformer and/or commands as a function of the thermal status of the transformer, and at least one control unit in communication with said one or more inputs and said actuation devices, said control unit being programmed to send actuation signals to the actuation devices so as to adjust the rotation speed of each fan as a function of the thermal status of the transformer.
