The utility model discloses a circuit breaker for a high-voltage switch cabinet, which comprises a mounting plate, the bottom of one end of the mounting plate is connected with a transverse plate, the top of the transverse plate is provided with a heat dissipation assembly for heat dissipation, the heat dissipation assembly comprises a rectangular pipe cavity, a fixing block and a screw rod, and the central position of the top of the transverse plate is connected with a circuit breaker body; when the lead screw rotates, the fixing block and the rectangular pipe cavity simultaneously move up and down in a reciprocating mode, and at the moment, high-speed airflow sprayed out of the rectangular pipe cavity acts on the circuit breaker body in an up-and-down reciprocating mode. According to the utility model, the motor rotates forwards and backwards to drive the rectangular pipe cavity to move up and down in a reciprocating manner, the air pump sucks air from the switch cabinet, the sucked air passes through the p
