1, overview

Outdoor high-voltage isolating type GW5 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 consistent with insulation distance safety requirements. Widely used in 35-110kV substation.

2, the main structure and characteristics

1, each isolation switch monopole is composed of a base, two pillar insulator, terminal block, around the contact assembly, grounding knife components;

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 of the product is greatly reduced.

3, two pillar insulator showed "V" type layout is installed on the same base, has the advantages of small occupied area, reduces the installation of metal structure;

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

5, through the bevel gear to rotate, so as to ensure the switching action two column agreement;

6, the two pillar axis angle is 50 degree, the rotation angle of 90 degrees, the brake after the insulation isolation fracture enough margin, so as to ensure the safety of;

7, which drives the base operating mechanism of crank arm, rod, the two pillar insulator synchronous rotation, so as to realize the switching operation,

8, 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;

9, 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 guarantee the static and the contacts in the contact position right or off position.
