12KV SF6 gas filled cabinet gas insulated electric outgoing spring operating mechanism

Instructions for use and operation

Inflatable cabinet mechanism located on the upper part of the mechanism, rotate the handle clockwise by about 90 °, and the mechanism scroll double spring compresses and stores energy. Press the closing button, and the closing energy storage spring is released. The main circuit of the load switch is closed under the mechanism releasing force.
Electric closing: When the mechanism is powered on and provides a closing signal, the mechanism controller will automatically determine the opening and closing positions of the load switch and the status of each interlocking circuit. If the status of each circuit reaches the condition for closing, the controller will activate the closing electromagnet to release energy and achieve instantaneous closing of the main circuit of the load switch.
Opening operation:
Manual disconnection: Press the disconnection button to release energy, and under the power of the released energy, push the load switch to complete the main circuit disconnection action. When the electric circuit is disconnected, a disconnection signal is given, and the controller will automatically distinguish the opening and closing positions of the load switch and the status of each interlocking circuit. If the status of each circuit reaches the condition for disconnection, the controller will automatically start the disconnection electromagnet to release energy, achieving the disconnection of the main circuit of the load switch. The institution can perform main circuit closing or grounding closing operations when in the open state.
Grounding closing and opening:
Grounding closing: Insert the dedicated handle of the mechanism into the grounding operation shaft at the lower part of the mechanism, rotate it clockwise by about 90 °, and the grounding energy storage spring will release energy instantly when compressed past the midpoint to push the grounding switch to complete the grounding closing. At this time, the mechanism is interlocked and locked, and the main circuit cannot be closed.
Grounding disconnection: Insert the dedicated handle of the mechanism into the grounding operation shaft at the lower part of the mechanism, rotate it counterclockwise by about 90 °, and the grounding energy storage spring will release energy instantly when compressed past the midpoint to push the grounding switch to complete the grounding disconnection. At this time, the mechanism interlock is in the open state, and the load switch can be closed or opened.
