Abstract
The invention relates to a wind cooling device of a secondary over-voltage protector of an intermittent current transformer. The wind cooling device comprises a shell (1), wherein a connection terminal (2) is arranged on the shell. The wind cooling device is characterized in that one side of the shell is provided with an elongated bottom plate (1b), a support (1c) is arranged on the elongated bottom plate, the side wall, corresponding to the support (1c), of the shell (1) is provided with a pipeline interface (1a), the other three side walls of the shell (1) are respectively provided with a plurality of heat dissipating holes (1b), a draught fan (3) is fixedly connected to the support (1c), a wind outlet of the draught fan (3) is connected with the pipeline interface (1a) through a pipeline, and a set of temperature sensors are arranged in the shell (1). The wind cooling device has the advantages that cooling is achieved through gas, so that the wind cooling device is good in ventilating and temperature reduction effects, and energy is saved; the device is favorable for prolonging the service life of the secondary over-voltage protector of the intermittent current transformer.
