Abstract

The utility model relates to a circuit breaker permanent magnetic operating mechanism for a vacuum circuit breaker, comprising a shell formed with a cylindrical inner cavity and a transmission rod vertically penetrating through the center of the shell, wherein a cylindrical armature is coaxially and fixedly assembled on the transmission rod in the shell; a control coil matched with the armature is arranged at the upper part of the inner cavity of the shell; a permanent magnet matched with the armature is arranged at the middle and lower part of the inner cavity of the shell; and a magnetic-isolating disc is fixedly arranged at the bottom of the inner cavity of the shell and below the armature. In the circuit breaker permanent magnetic operating mechanism, the permanent magnet is applied in the operation mechanism, so that the maintenance of the switching-off and switching-on positions of the vacuum circuit breaker is realized by the permanent magnet, compared with a traditional spring or electromagnetic operating mechanism, moving parts are greatly reduced, the manufacturing process is simplified, the acting speed of the operating mechanism and the reliable performance and the service life of a product are greatly improved.
