Abstract
The utility model discloses a breaker release trip-out device. The device comprises a coil frame that is internally provided with a permanent magnet and an iron core that are distributed in the axial direction of an insulation cylinder frame. The coil frame is sleeved by a coil and a magnet yoke. The permanent magnet and the iron core are arranged in the direction from the bottom part of the insulation cylinder frame to the top part of the insulation cylinder frame. The side, which is near the top part of the insulation cylinder frame, of the permanent magnet is provided with a push rod. The push rod extends outside the iron core and towards the direction of departing from the iron core. The extended terminal part of the push rod is connected to a tripping sheet. The side part of the tripping sheet is provided with a tripping sheet aperture groove. A spring is disposed between the permanent magnet and the iron core. The spring sleeves the outer side of the push rod. The permanent magnet and the iron core of the breaker release trip-out device utilize the principle of current and magnetic field cooperation in a coil for repulsion or attraction. The iron core and the permanent magnet are disposed in the coil frame, and the cylinder frame structure is utilized, so that other components are prevented, and structure is simpler.
