CJ23-550-PG three-station electric operating mechanism is a dual-motor three-station mechanism designed according to the special requirements of Pinggao ZF27-550. The output torque of this mechanism is large, the opening and closing time is within 1s, and the output angle is large (more than 1 turn). It can be used for the closing and breaking of ZF□-550GIS and the disconnector, earthing switch and load switch with the required torque equivalent to that of the single phase.
This mechanism is a three-station mechanism, and one mechanism can operate an isolation switch and a grounding switch, so as to realize the functions of closing and opening of the isolation switch and closing and opening of the grounding switch. The mechanism has two operation modes at the same time: manual and electric.
Through the forward and reverse rotation function of dual motors, this mechanism uses the transmission of mechanical clutch, worm gear and worm and crank pulley to ensure the differentiation of opening and closing position and output angle, and can fine-tune the output angle through mechanical clutch and magnetic blowing switch.
