Abstract

The invention relates to a direct pulling type residual current operated tripping mechanism, which mainly solves the problems of complex structure, troublesome assembling and high manufacturing cost of an existing tripping mechanism. The direct pulling type residual current operated tripping mechanism is characterized by comprising a coil assembly, a movable iron core, a pull rod and a reset button which are arranged in a base of a circuit breaker; the coil assembly is fixedly mounted in the base; the movable iron core is slidably arranged at the center of the coil assembly; the pull rod is hinged to the base and is in linkage cooperation with the movable iron core and an operating mechanism of the circuit breaker; the reset button is mounted on the base and is in linkage connection with the pull rod. The direct pulling type residual current operated tripping mechanism has the advantages of reliable tripping performance, simpler structure, fewer parts, and more convenience in assembling.

Description

technical field [0001] The invention relates to a tripping mechanism of a circuit breaker, in particular to a direct pulling type residual current action tripping mechanism. Background technique [0002] Leakage circuit breaker is an electrical safety switch device that can quickly cut off the power supply and prevent electric shock accidents when personal electric shock or electric leakage occurs. [0003] Generally, for a circuit breaker with residual current protection, the tripping mechanism is composed of a driving device and a ejector rod. The driving device has an electromagnetic release that generates a driving force and a mechanism that can amplify the generated driving force. When the residual current exceeds the specified value, the electromagnetic release drives the amplifying mechanism to act together, so that the four-bar linkage mechanism of the main switch breaks the balance, and the main switch is disconnected. This kind of mechanism generally has complex s...
