General

HXGN15-12 high voltage ring network cabinet with spring operating mechanism is the affiliated equipment used for Alternating-current metal-enclosed switchgear of Rated voltages 12 kV. This series of operating mechanism takes usage of the energy of flat spiral spring to control the action of the load switch and the earthing operation uses the energy from the compression spring. There are three working positions for this operation mechanism. That is CLOSING, OPENING and EARTHING.  This series of operating mechanism has Five Preventions Interlocking functions as well as the distinguishing features of small size, easily to install and adaptable.

The product is qualified according to the delivery inspection. It conforms to relative requirements of GB3804-2004 “High-voltage alternating-current switches for rated voltage above 3.6 kV and less than 40.5 kV”, GB3906-2006 “Alternating-current metal-enclosed switchgear and control gear for rated voltages above 3.6 kV and up to and including 40.5 kV”, GB16926-2009 ” High-voltage alternating current switch-fuse combinations”.

Operating instructions for spring mechanism

Stored-energy operation

Make sure to check the product has no deformation due to the transportation before install and fix it on the switchgear. Use the special operating handle to insert it into the lower right part of the mechanism and rotate it clockwise(or turn on the motor) until it clicks. The operation of stored-energy is completed.

CLOSING operation

Rotate the green knob and the switch of circuit breaker is CLOSING under the action of the structural spring force. Or during electric operation, the charging mechanism of the closing coil completes the closing operation. At the same time, make energy for the spring to make OPENING operation . At this time, the energy can be stored again, but the closing operation (with interlocking) can no longer be performed.

OPENING operation

Rotate the red knob and the switch of circuit breaker is OPENING under the action of the structural spring force. Or during electric operation, the charging mechanism of the closing coil completes the OPENING operation.
