Permanent magnet release and control circuit thereof

The utility model provides a permanent magnet release and a control circuit thereof. The permanent magnet release comprises a magnet yoke, a permanent magnet fixed on the inner surface of the magnet yoke, a coil assembly arranged in the magnet yoke and provided with a reset coil and a release coil, a magnetic conductive piece fixed on the permanent magnet and embedded into the coil assembly, a magnetic conductive movable iron core slidably arranged in the coil assembly in a penetrating mode, and an elastic piece abutting between the magnetic conductive piece and the magnetic conductive movable iron core. Wherein the permanent magnet is demagnetized by using magnetic flux generated by the trip coil, and the purpose of quick trip is achieved under the driving action of the elastic piece; the electric reset process of the magnetic conductive movable iron core is achieved through the reset coil, and reset of the magnetic conductive movable iron core and energy storage of the elastic piece are completed.
