Abstract

The invention discloses a current-limiting type circuit breaker with an anti-seismic property. The circuit breaker comprises a shell base and an upper cover. The shell base is provided with a thermaltripping mechanism composed of a tripping mechanism and a bimetallic strip. The current-limiting circuit breaker also comprises a thermal tripping pull rod. A sliding rail is arranged on the upper cover; the thermal tripping pull rod is connected with the sliding rail in a sliding manner; the upper cover is buckled with the shell base; the thermal tripping pull rod is arranged between the trippingmechanism and the bimetallic strip; and one end of the thermal tripping pull rod is connected with the bimetallic strip, the other end of the thermal tripping pull rod is close to the tripping mechanism at a set distance, the thermal tripping pull rod and the tripping mechanism of the circuit breaker cannot be contacted in a normal state, and when the bimetallic strip is heated and deformed, theother end of the thermal tripping pull rod triggers the tripping mechanism to realize power failure and tripping. The current-limiting type circuit breaker with the anti-seismic property is simple instructure and high in anti-seismic capability, and a phenomenon of false tripping caused by a fact that vibration of a tripping pull rod is conducted to the tripping mechanism of the circuit breaker can be reduced.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a current-limiting circuit breaker with anti-seismic performance. Background technique [0002] Thermal tripping current-limiting circuit breakers generally use the thermal deformation of the bimetallic memory element to pull the tripping device of the circuit breaker to power off and trip. The pull rod between the bimetallic sheet and the tripping mechanism of the circuit breaker generally adopts a free connection structure. When there is a vibration force from the outside, the thermal trip lever will also vibrate, which will easily cause false tripping. Contents of the invention [0003] The object of the present invention is to provide a current-limiting circuit breaker with anti-seismic performance, which has a simple structure, strong anti-seismic ability, and can reduce false tripping. [0004] To achieve the above object, the present invention provides the foll...
