HYT5D Electric Spring Mechanism

HYT5D Electric Spring Mechanism

The HYT5D 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.

spring can achieve rapid operation with manual and electric functions

This mechanism is a spring machine with manual and electric operation functions.

The mechanism use the positive and negative turn functions of the motor by principle of spring symmetry so that the mechanism compression spring can achieve rapid operation. The output angle can be adjusted finely by oil buffer and magnetic blowout switch.
