The left and right sides of the high-voltage switch cabinet are provided with heat dissipation ports, and the side of the annular plate away from the high-voltage switch cabinet is fixedly connected with a positioning frame. Through the high-voltage switch cabinet, the bidirectional stepping motor located at the back of the high-voltage switch cabinet is started, and the fixed rod transmits the rotating force to the rotating rod through the belt, and the rotating rod drives the fan blade to rotate, so as to achieve the effect of heat dissipation inside the high-voltage switch cabinet, and avoid the problem of short circuit caused by excessive internal temperature of the high-voltage switch cabinet.

[0013] A plurality of groups of heat dissipation holes distributed at intervals are arranged around the heat dissipation cover.

[0014] Beneficial effects of the utility model:

[0015] The utility model uses a transmission structure composed of a pulley and a transmission belt to make the two sets of exhaust fans rotate together when the servo motor controls the driving shaft to rotate, so that the hot air inside the switch cabinet is sucked into the junction box, and then the hot air is blown out downward through the longitudinal air duct and the transverse air duct.
