Outdoor GW9-10 high voltage Insulation Switch

A, use

(H) the outdoor high-voltage isolating switch is GW9-10 single-phase AC 50Hz high voltage switch equipment, used for rated voltage of 10kV power system, as have no load voltage situation on or isolated power supply for. Operate with the insulative stick of the isolating switch.

Two, the use of the environment

A, an altitude of more than 1000 meters;
B, ambient air temperature: +40 ℃ upper limit, lower limit of normal in -30 ℃,-40 ℃ in alpine region;
C, the pressure is not more than 700Pa (corresponding to the wind speed 34m/s);
D, seismic intensity does not exceed 8 degrees;
E, without frequent violent vibration place;
F, the ordinary type of installation place where gas, no serious effect of isolating switch insulation and conductive ability of steam, chemical deposition, salt fog, dust and other explosive, corrosive substances. Anti pollution type applies to heavy pollution area, but should not cause fire and explosive substances.

Three, the structure and working principle

The isolating switch for single-phase type structure, each phase is composed of part of underframe, pillar insulator, knife, contact. The knife surface contact pressure spring adjusting screw and press use, is provided with a fixed buckle and a self-locking device connected to the insulating rods, hooks for switching purposes.

In the structure compared with non modified products of this series of products with higher contact area, low contact resistance, good electrical conductivity, mechanical strength advantages.

Four, the installation of the product

This isolation switches generally use the flip chip, can be vertical or inclined installation (moving contact below), with the M12D bolts will frame is fixed on the cross arm on the right position, should be on the ground with a link bar hook and switch on, and make sure the chassis will not loose operation. Wire shall be connected to the static contact side, wire shall be connected to the movable contact side, keep a proper distance should be three-phase switch, to avoid short circuit.
