The embodiment of the invention provides a circuit breaker contact, a circuit breaker and a high-voltage switch cabinet. The circuit breaker contact comprises a plum blossom rack, a wireless temperature sensor and a plurality of plum blossom contact fingers, wherein, the wireless temperature sensor and the plum blossom contact fingers are inserted on the plum blossom rack along the circumferentialdirection. Circuit break contacts provide by embodiments of that present invention, Circuit breaker and high-voltage switchgear include a plum blossom rack, Wireless temperature sensors and a numberof plum blossom touches, the wireless temperature sensor is installed in the same way as the plum blossom touch finger, which is inserted on the plum blossom rack along the circumferential direction,The wireless temperature sensor becomes a part of the circuit breaker contact, is fixed and stable, and is difficult to fall off. The wireless temperature sensor is directly arranged on the circuit breaker hot spot of the high-voltage switch cabinet, namely the circuit breaker contact, and the measuring point is a direct heating source. The temperature measurement is accurate, the response speed is fast, and the real-time monitoring of heat emission point temperature of the high-voltage switch cabinet is realized.
