Abstract

A manual closing mechanism for a permanent magnetic mechanism comprises a connecting rod, a disc spring assembly, a closing output crank arm, a cam, an opening detent, an opening half shaft, a large gear, a pinion, an energy storage pawl, a pawl limiting plate, a closing spring, an energy storage variable four-rod mechanism, a triangular crank arm and a closing handle. The pawl limiting plate is fixedly arranged on the connecting rod; the pawl limiting plate is connected with the energy storage pawl in a matched mode; the energy storage pawl is meshed with the pinion; the pinion is meshed withthe large gear and transmits torque to the closing spring through the large gear; the cam is connected with the closing spring, the cam and the large gear are coaxially arranged, the cam is connectedwith the closing output crank arm, the closing output crank arm is connected with the connecting rod through the disc spring assembly, the closing output crank arm is connected with the opening detent, the opening detent is connected with the opening half shaft, and the opening half shaft is connected with the closing handle through the energy storage variable four-rod mechanism. The manual closing mechanism for the permanent magnetic mechanism is compact in structure and reliable in action, and has closing capacity.

Description

technical field [0001] The invention relates to the technical field of switching equipment, and relates to a manual closing mechanism of switching equipment such as a permanent magnet mechanism recloser, a circuit breaker or a load switch, in particular to a manual closing mechanism for a permanent magnet mechanism. Background technique [0002] At present, a large number of vacuum circuit breakers, reclosers or load switches using permanent magnet mechanisms are installed in medium voltage power distribution systems. These vacuum switches using permanent magnet mechanism have many advantages such as less moving parts, high reliability, short energy storage time (capacitive energy storage), fast movement speed, etc., and can perform multiple rapid reclosing in a very short time. It is widely used in distribution network, especially outdoor distribution network. Temporary faults in outdoor distribution networks account for 70% to 80%. Switchgear using permanent magnet mechan...
