CJ10B Three Position Mechanism

CJ10B Three Position Mechanism

The CJ10B multi-turn output electric operation three position mechanism mechanism can be used for12kV、24kV、40.5kV ring main unit and GIS as well as isolating switch, grounding switch and load switch which have the same required torque.

The mechanism is a three position mechanism, each can operate a isolation switch and a grounding switch to achieve closing and opening with manual and electric operation modes.

This mechanism is a single-motor three position mechanism with multiple turns of output. The motor directly operates the switch assembly through the electromagnetic clutch; the multi-angle output is controlled by the travel switch and the mechanical limit device; and the position switch is accurately reflected by the travel switch instead of the auxiliary switch. The mechanism has an electromagnetic clutch that can guarantees the output of the three positions.
