Abstract
The invention provides a circuit breaker for preventing misoperation after short circuit. The circuit breaker comprises a circuit breaker circuit, an operating mechanism, a conductor structure, an arc-extinguishing device and a tripping mechanism. The tripping mechanism comprises an intelligent module and an electromagnetic system. The electromagnetic system comprises a coil which generates a magnetic field and a moving iron core which is arranged in the coil. An acquisition device for detecting short circuit of a circuit is arranged relative to the tail part and/or the top part of the moving iron core. The acquisition device is electrically connected with the intelligent module. The acquisition device adsorbs the moving iron core through the magnetic field generated by the coil. When the moving iron core leaves the acquisition device, the intelligent module receives the short circuit signal of the acquisition device and then a motor is locked in the out-of-operation state, i.e. the circuit breaker cannot be closed. The intelligent module is also provided with a fault indication device. The acquisition device is a travel switch and/or a micro-switch and/or a photoelectric switch. The beneficial effects of the circuit breaker are that the circuit breaker is simple in structure and convenient to use and can greatly detect the short circuit state of the circuit and prevent short circuit misoperation of the circuit.
