HYJ4D Electrically Operated Mechanism

HYJ4D Electrically Operated Mechanism

The HYJ4D operating mechanism can be used for 550kV GIS isolating switch, grounding switch as well as isolating switch, grounding switch and load switch which have the same required torque.

This mechanism is an electric machine with manual and electric operating modes.

The mechanism use torque controller and worm and gear to ensure opening and closing position and output angle by forward and reverse function of motor and can finely adjust the output angle through eccentric and magnetic blowout switch.
