Background
The permanent magnetic mechanism circuit breaker is a device capable of instantly cutting off a fault circuit on a line and protecting power supply equipment. The existing permanent magnet mechanism circuit breaker is widely applied to the field of power equipment due to the advantages of reliable performance, long service life and the like. The breaker comprises a permanent magnetic mechanism and a vacuum bubble, wherein the permanent magnetic mechanism comprises a break-brake static iron core, a close-brake static iron core, a movable iron core, a permanent magnet, a break-brake coil and a close-brake coil, the break-brake coil and the close-brake coil are arranged at two ends of the permanent magnetic mechanism, the movable iron core can be controlled to be attracted to the break-brake static iron core or the close-brake static iron core through the break-brake coil and the break-brake coil, and the movable iron core can move up and down. Chinese patent CN205230960U discloses a permanent magnet mechanism for high voltage circuit breaker. The vacuum bubble is an electric element integrating on-off circuit, arc extinction and insulation, and is connected with the permanent magnet mechanism through a pole pull rod of the vacuum bubble, so that the movable iron core of the permanent magnet mechanism drives the pole pull rod to move up and down when moving up and down, and further the on-off of a power system circuit is realized. However, the existing permanent magnet mechanism needs a standby power supply (generally a storage battery) to provide an action power supply for a mechanism coil, once a standby power supply circuit fails and cannot work, the permanent magnet mechanism cannot realize switching-off and switching-on, and potential safety hazards exist. Therefore, the manual switching-on and switching-off mechanism (refer to the specification) is added on the basis of the existing permanent magnet mechanism circuit breaker, the manual switching-on and switching-off mechanism is connected with a driving shaft arranged at the lower end of a movable iron core, and the manual switching-on and switching-off mechanism drives the movable iron core to move up and down through the driving shaft when in use, so that switching-on and switching-off can be independently completed without the participation of a standby power supply. However, the existing permanent magnet mechanism circuit breaker shell cannot be used in cooperation with the manual switching-on and switching-off mechanism of the inventor, and therefore a novel permanent magnet mechanism circuit breaker shell needs to be designed.
