Abstract
The invention relates to an emergency manual switching-off mechanism for a permanent magnet medium voltage dual-power-supply conversion switch. The emergency manual switching-off mechanism mainly comprises an A power supply permanent magnet assembly, an A power supply pull rod, an A power supply lever, a B power supply lever, a B power supply pull rod, a B power supply permanent magnet assembly, a B power supply basic shaft, a B power supply connecting shaft, a B power supply connecting rod, a rotary shaft fixing frame, a rotary shaft, an A power supply connecting rod, an A power supply connecting shaft, an A power supply basic shaft, an A power supply torsional spring, a B power supply torsional spring, a B power supply limiting pin, a B power supply limiting-baffling pin, an A power supply limiting-baffling pin, an A power supply limiting pin, a lever limiting groove, a connecting shaft I, and a connecting shaft II. When the rotary shaft is rotated by a handle, the rotary shaft drives the levers to rotate around the basic shafts through the connecting rods; the levers drive the pull rods to move, and a movable iron core and a static iron core of a permanent magnet driving mechanism are separated; meanwhile, the levers tightly compress the torsional springs for energy storage; and when the force from the handle is stopped, the torsional springs in the compressed state release energy to drive the levers to be reset. The emergency manual switching-off mechanism is convenient in overall operation, and stable and reliable in performance.
