The invention discloses a circuit breaker fixing device with an ice and snow frost crack prevention structure, and the fixing device comprises a box body and a box body door, and is characterized in that heat dissipation devices for heat dissipation are welded on the two side surfaces of the box body, and a frost crack prevention supporting box body module is connected to the inner side of the box body through bolts and nuts; a heat dissipation oil conveying pipe used for preventing frost cracking and conveying high-temperature oil is inserted into the circuit breaker, a frost cracking prevention device is arranged on the box body, the box body wall of the box body is composed of a supporting outer wall, a supporting inner wall and a vacuum layer, and a heat dissipation device is composed of a supporting frame, an air blower, a filter screen, a hydraulic lifting device and a heat dissipation box body door; an oil storage cavity is formed in the anti-frost-crack supporting box body module, the anti-frost-crack device is composed of a circulating oil pump, a heater, a heating wire and an electric control box. According to the invention, the anti-frost-crack effect is achieved through the box body, the anti-frost-crack device and the anti-frost-crack supporting box body module, the service life of the circuit breaker is prolonged, and the safety performance is improved.
Description
Technical field [0001] The present invention relates to a circuit breaker Technical Field fixing means, particularly fixing means of a circuit breaker structure having a freezing burst prevention ice. Background technique [0002] Circuit breakers are widely used in a three-phase power distribution systems switchgear key supporting member, for industrial and mining enterprises, substations and other sectors as a control and protection of electrical installations used, especially for frequent on, off operation place. [0003] Fixing means having a conventional ice breakers freezing burst prevention structure, the circuit breaker operating under harsh outdoor environment, particularly snow and ice caused the cracking temperature is too low, thus affecting the normal use. Inventive content [0004] Object of the present invention is to solve the problems set forth above, and proposed a circuit breaker fixture ice freezing burst prevention structure. [0005] To achieve the above ob...
