1 ,Product overview
1.1 Application
GW1A type outdoor AC high voltage isolation switch is AC 50Hz/60Hz outdoor device, is used in below 33 kv the supply network, for high voltage line and under the situation with voltage, as well as on the maintenance of high voltage bus, circuit breakers and other electrical equipment with high voltage line charged electrical isolation. But also switch small capacitance current and inductive current.
This product is divided into regular and anti-pollution type two kinds.
CJ6 Motor or CS8-5 rainproof type manual.

3, Construction
This disconnector(Size as shown in figure 1)is the three-phase on one chassis knife switch, or made up of three single phase.As shown, can be divided into the chassis, insulator and conductive parts, chassis by the rotor and the bending of plate and Angle steel welded frame, chassis fixed six porcelain insulator, and every two composition, mounted on the rotating shaft three-phase insulator to operate, and close movement used to operating three-phase knife, conductive part is composed of contactor, knife and contact, with the spring pressure.
Break-brake in turn by the operating arm shaft rotates, operating insulator up divide the knife and contact with the knife, knife touch the revolving around, contact also in knife leads up to the gate location.
Turn by the operating arm shaft rotates when closing, turns operating insulator with the knife, in and after contact to meet contact rotates, together go to closing position.
