Abstract

The utility model relates to a manual separating mechanism for a permanent magnet vacuum circuit breaker. The manual separating mechanism comprises a support, at least one permanent magnet mechanism, a rotating shaft, at least one separating brake transmission assembly, a movable plate, a push rod and a push rod driving mechanism. The permanent magnetic mechanism has a movable pull rod capable of moving up and down relative to the bracket; the opening transmission assembly comprises a swing arm, a front pressing plate and a rear pressing plate, the middle of the swing arm is hinged to the support, the front end of the swing arm is movably connected with the lower end of a movable pull rod of the permanent magnetic mechanism, the lower end of the front pressing plate is fixedly connected to the rear end of the swing arm, and the rear pressing plate is fixedly installed on the rotating shaft. The rear pressing plate is located below the rear portion of the front pressing plate and is in contact fit with the front pressing plate. The movable plate is fixedly installed on the rotating shaft, the push rod is installed on the support in a front-back translation mode and located behind the movable plate, and the front end of the push rod is in contact fit with the movable plate. According to the manual opening mechanism for the permanent magnet vacuum circuit breaker, emergency manual opening operation can be realized, the manual opening process is simple and labor-saving, and the manual opening action is quicker.
