Abstract
The invention provides a permanent-magnet vacuum circuit breaker switch, which comprises a permanent-magnet operation mechanism, a vacuum embedded pole, a main shaft and a switch frame body. When a closing solenoid coil is powered on by a vacuum circuit breaker controller, a movable iron core push rod assembly is drawn to adhere to a closing iron core under the effect of the magnetic field attraction force. Meanwhile, the action of a magnetic field is generated by the movable iron core push rod assembly and a permanent magnet, so that the movable iron core push rod assembly is actuated to extend towards a closing end. The main shaft is driven to rotate by an output transition connecting lever assembly, and then the pull-rod connecting lever of the main shaft pulls an insulated pull rod in the upward linkage manner. In this way, the closing state is realized. The opening state can be realized on the contrary. According to the technical scheme of the permanent-magnet vacuum circuit breaker switch, the outer shell and the vacuum explosion chamber of the embedded pole are made of an insulating medium, so that the dual insulation arc-extinguishing effect is realized. No existing mechanical type operating mechanism is adopted, so that the number of transmission members is reduced. The opening/closing state of the permanent-magnet vacuum circuit breaker switch is controlled based on the manual operation of a cam mechanism or a vacuum circuit breaker controller of a permanently magnetic mechanism.
