This series of mechanisms adopts flat spiral spring energy storage to control the action of the load switch, and the grounding operation adopts compression spring energy storage control. There are three operating stations for closing, opening, and grounding in the work position. This series of products has five interlocking functions, small size, easy installation, and strong adaptability. This product has passed the full inspection and is in compliance with the relevant requirements of G8 3804-2004 "3.6kV-40.5kV High Voltage AC Load Switches", GB 3906-2006 "3.6-40.5kV AC Metal Enclosed Switchgear and Control Equipment", and GB16926-2009 "High Voltage AC Load Switchgear Fuse Combination Electrical Appliances".
Operatinginstructions for spring mechanism
Closing operation
Make sure to check the products without transportation will be fixed on thedeformation mechanism of load switch, the use of the operating handle is insertedinto the upper part of special institutions, clockwise rotation about 90 degrees, theload in the body underthe action ofthe spring force main loop switch. Or the electricoperation, press the closing button, the motor drives the mechanism to completethe switch on and turn operation, at this time can not carry on the ground operation.
Switching operation
The operating handle is inserted into the upper part of the mechanism and rotatescounterclockwise about 90 degrees, and the load switch is operated under theaction of the force ofthe mechanism spring, and the main circuit is split. Or electricoperation, according to the switch button, the motor drives the mechanism tocomplete the switching operation, at this time, it can do the closing operation or thegrounding operation.
Earthing closing and earthing switching operation
The operating handle is inserted into the lower part of the mechanism and rotatesabout 90 degrees clockwise. The load switch is closed to the ground circuit underthe action of the force of the mechanism spring, so that the main circuit closingoperation can not be performed at this time.The operating handle rotates about 90 degrees counterclockwise, and the loadswitch switches the grounding circuit under the action of the force of the mechanismspring, which can be used for closing operation or grounding operation.
