Therefore, the closing and opening operation is generally realized by manual operation, and after rotating by a certain angle, the closing and opening of the isolating switch main body is operated, and the operation of the operation assembly can only be carried out locally, and remote control cannot be realized, and the operation time is generally greater than one second. SUMMARY

[0003] The utility model discloses an isolating switch operation mechanism, and the operation assembly is the mechanism with pre-stored energy widely used in frame circuit breaker, the mechanism energy storage spring is stored energy through electric or manual operation assembly, the mechanism is in the closing position through the operation closing trip or closing button, the isolating switch main body is closed through the transmission mechanism, the mechanism is in the opening position through the operation opening trip or opening button, and the isolating switch main body is opened through the transmission mechanism.

[0004] In order to achieve the above purpose, the main technical scheme of the utility model adopts:

[0008] When closing operation is carried out, the energy storage of the first energy storage spring is completely released, at this time, the electric energy storage mechanism starts to start, and the first energy storage spring is stored energy again until the energy storage is completed, and the electric energy storage mechanism is automatically stopped.

[0009] When the closing operation is performed, the energy storage of the first energy storage spring is released, and part of the energy is transferred to the opening energy storage spring and the energy storage adjusting spring, and the opening energy storage spring and the energy storage adjusting spring are released by manually operating the opening button or electrically operating the opening trip.

[0010] The mechanism transmission main shaft drives the disconnecting switch main shaft to rotate through the transmission mechanism, and therefore, different cooperation between the mechanism transmission main shaft and the disconnecting switch main shaft can be obtained by changing the transmission mechanism, and when the rotation angle of the mechanism transmission main shaft is fixed, the rotation angle of the disconnecting switch main shaft can be changed, and therefore, the mechanism can be adapted to disconnecting switch main bodies with different rotation angles of the main shaft.
