Overview
The fully insulated and compact ring network cabinet CF spring operating mechanism is a matching equipment for rated voltage 12kV AC metal-enclosed switchgear. This series of mechanisms adopts the flat scroll spring energy storage to control the action of the load switch. The Earthing operation uses to control during the spring compression. The working position has three operation working-position: closing, opening and earthing. The series has five anti-interlocking functions, small size, convenient installation and strong adaptability.
The product is fully qualified and shipped to the factory, conform to GB3804-2004 “3.6kV-40.5kV high voltage AC load switch”, GB3906-2006 “3.6-40.5kV AC metal-enclosed switchgear and control equipment”, GB 16926-2009 “high voltage AC load switch – Fuses combined electrical appliances related requirements.

GH-12(C) spring operating mechanism operation construction
1. Closing operation:
Check whether the product is deformed or not during transportation. Install the mechanism on the load switch, insert into the upper part of the mechanism with a special operating handle, rotate it clockwise by about 90 degrees, and close the main circuit under the action of the spring force of the mechanism. Or electric operation according to the closing button motor to drive the mechanism to complete the switch closing operation, at this time can not be grounded.
2.Opening operation:
The operating handle is inserted into the upper part of the mechanism, rotated about 90 degrees counterclockwise, and the main circuit is opened by the load switch under the action of the mechanical urging force. Or press the opening button during electric operation, and the motor drives the mechanism to complete the opening operation. At this time, can do closing operation or earthing operation.
3. Earthing closing and earthing opening operation:
The operation handle is inserted into the lower part of the mechanism and rotated clockwise by about 90 degrees. The load switch is closed by the spring force of the mechanism, and the main circuit closing operation cannot be performed at this time.
The operating handle is rotated about 90 degrees counterclockwise, and the load switch is opened under the action of the spring force of the mechanism. At this time, the closing operation or the earthing operation can be performed.
