Problems solved by technology
However, realizing the operation of the permanent magnet mechanism through an external power supply takes up resources and wastes electric energy. Especially in an emergency, the permanent magnet mechanism cannot be provided with an external power supply, resulting in the permanent magnet mechanism being forced to stop working.

The invention discloses a manual breaking or closing device for a permanent-magnet operating mechanism of a high-voltage breaker. The manual breaking or closing device comprises a permanent-magnet mechanism, a control module, a power generation device, a capacitor and a breaking or closing device, wherein the power generation device is connected with an input end of the control module; the breaking or closing device comprises a closing circuit and a breaking circuit; an output end of the control module is sequentially connected with the permanent-magnet mechanism, the capacitor, the closing circuit and the breaking circuit; and the output end of the permanent-magnet mechanism is connected with the closing circuit and the breaking circuit in series. The manual breaking or closing device has the beneficial effects that when the permanent-magnet mechanism cannot be provided with an external power supply, the device can charge the energy storage capacitor of the permanent-magnet mechanism by only being manually driven by manpower; and meanwhile, the device integrates the power generation device in the permanent-magnet mechanism, so that the occupied space is small.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a manual opening and closing device and method for a permanent magnet operating mechanism of a high-voltage circuit breaker. Background technique [0002] At present, in the existing high-voltage circuit breakers, the permanent magnet operating mechanism of the circuit breaker does not have the functions of manual energy storage and manual closing, and the energy storage process is realized by charging high-energy energy storage capacitors. Now, in practical applications, it is generally necessary to provide an additional energy storage power supply for the permanent magnet mechanism of the circuit breaker to charge the high-energy energy storage capacitor. Therefore, after the switch arrives at the site, the closing operation can only be performed through an external power supply, and then the closing operation is performed, that is, the operation of the permanent magn...
