Problems solved by technology

Over-current phenomenon is easy to occur when the electrical appliances are used. When the electrical appliances are over-current, it is easy to cause the electrical appliances to burn. There is often no automatic circuit breaker locking function, therefore, we propose an AC dual-power switching device that automatically locks out when the hardware fails

Abstract

The invention relates to the technical field of circuits, and discloses an alternating-current double-power switching device capable of automatically locking during hardware failure, which comprises a device main body, a power line is fixedly connected to the outer side of the device main body, a current guide rod is fixedly mounted in the device main body, a bearing plate is fixedly mounted in the device main body, a current coil is fixedly installed in the device body, an electromagnetic coil is fixedly connected to the outer side of the current coil, an electromagnetic assembly is fixedly connected to the lower portion of the electromagnetic coil, a first magnet is fixedly installed in the electromagnetic assembly, and a sub-magnet is fixedly connected to the outer side of the electromagnetic assembly. According to the alternating-current double-current switching device capable of automatically locking in the case of hardware failure, the two groups of trigger switch heads compress the switch wires to abut against each other, the interior of the device main body is electrified, and the locking mechanism is started immediately to lock the device main body, so that the purpose of automatic locking is achieved.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to an AC dual-power switching device that automatically locks when hardware fails. Background technique [0002] The invention and application of electric power set off the second industrialization climax; with the continuous development of social economy, the growing demand for electric energy supply in life and production has strongly stimulated the rapid development of electric power system. The spatial distance between the energy center and the load center is the objective motivation for large-capacity and long-distance transmission of electric energy. In order to meet the needs of power transmission, the size of the power network is increasing day by day. Over-current phenomenon is easy to occur when the electrical appliances are used. When the electrical appliances are over-current, it is easy to cause the electrical appliances to burn. There is often no automatic circuit b...
