HBC-12 Plywood type ring main unit isolating switch operating mechanism 12KV
PRODUCT DETAILS
◆Closing operation of isolating switch
Install and fix the mechanism on the body, use a special operating handle to insert into the upper part of the mechanism (closing operating shaft), rotate it 90 degrees clockwise, and the load switch will close the main circuit under the action of the spring force of the mechanism.
or use electric operation to press the closing button and the motor drives the mechanism to complete the switch closing operation.
◆Opening operation of isolating switch:
Use a special operating handle to insert into the upper part of the mechanism (closing operating shaft) and rotate it counterclockwise about 90 degrees. The main circuit opens under the action of the spring force of the mechanism. Or use electric operation to press the opening button and the motor drives the mechanism to complete the switch opening operation.
◆Ground closing operation of the isolating switch:
The operating handle is inserted into the grounding operating shaft (lower part) and rotates 90 degrees clockwise. The body closes the grounding circuit under the action of the spring force of the mechanism.
●Ground opening operation of the isolating switch:
Rotate the operating handle about 90 degrees counterclockwise, and the ground circuit of the body opens under the action of the spring force of the mechanism.
