Product Details

Model Number: GW4 (H)GW9 (H)GW5

Brand Name: Histe

Key Specifications/Special Features:

High-pressure isolating switch (porcelain type)
The generation of isolating switch effect of principle and basic working principle is: one is isolating switch was under high voltage; two is isolating switch the conductivity of the surface is unclean. When wet environment, such as the heavy fog, dew, drizzle, isolating switch surface layer of conductive material unclean conductivity increases, insulation resistance decreased. In normal working voltage leakage current rise, the leakage current joule heating make isolating switch partial surface drying; Dry area surface resistance increases, isolating switch of the surface of the voltage distribution change, dry area's contribution to the voltage increase, and when the voltage more than breakdown voltage, it happened along the surface partial discharge, form the leakage current pulse: if isolating switch string all isolating switch dry area were breakdown, they form large leakage current pulse.

Isolating switch is a kind of high voltage switch electric appliances, is a no arcing device switch equipment, mainly used to disconnect no load current circuit, the isolation power, at break-brake has obvious disconnect point of the state, to ensure the safety of the other electrical equipment maintenance. In the state of feeder can reliably through the normal load current and short circuit fault current. Because it does not have special arcing device, can't cut off the load current and short circuit current. Isolating switch in the electric power industry is widely used in according to relevant way and method of use, often for isolating switch inspection; guarantee in use won't produce stone the cause of the actual effect. Rated current of the switch has: 200; 400; 600 and 1000 A. They are the base, post insulator, conductive part and institutions parts. The knife type structure points to cut off and closed circuit. Each phase by two pieces of conductive blade knife of two side blades with the spring compression, adjust the height of the spring can get the knife switch to contact pressure. Switch points off in the insulation operator may to close brake movement. The knife has self-lock device.
