1, overview

Outdoor high-voltage isolating type GW4 switch is used for three-phase AC 50Hz outdoor high voltage electrical equipment, for the line of a voltage at no load condition, and the high voltage line of electrical equipment and charged the maintenance of high voltage bus, circuit breakers and other electrical isolation purposes, can also be used for the opening and closing of small capacitance or inductance current. The knife in the normal brake position, can provide a meet safety requirements

Insulation distance. Widely used in 35-220kV substation.

2, the main structure and characteristics

1, isolating switch for double column horizontal rotation type, composed of a base, post insulators, wire holder, or contact assembly, grounding knife etc.;

2, the contact finger and the contact finger seat is connected by shaft pit, between the wiring board and the touch rod adopts soft copper connections, so that the main loop resistance products than the old structure greatly reduced.

3, two pillar insulator is fixed on the rotating disc bearing seat on the upper end of the left and right respectively, the contact is fixed in the insulator, the operating mechanism drives the rotating disk, the prop driven contact arm to rotate 90 degrees, a pillar of the rotating disk because of cross linkage driving and reverse rotate 90 degrees to one side, then switch off open or closed. Contact distance, with an insulating isolation fracture enough margin, so as to ensure the safety of;

4, a rolling shaft, easy operation, flexible rotation, freely.

5, products are not grounding, grounding, single double ground in three ways, a mechanical linkage between the spindle and reliable grounding, so as to ensure the safety of;

6, with CJ2 automatic operation mechanism of CS-17G manual mechanism and so on, can be attached to an electromagnetic lock. Positioning on the mechanism device, can ensure that the contact position of contact and the static contact head is in the correct position or breaking.
