Introduction of Vacuum Switchgear and its Driving Mechanism

Feb 24, 2012 · This makes, vacuum switchgear, most suitable for capacitor switching. Low Arc Energy in Vacuum. The energy dissipated during arc in vacuum is about one tenth of that of oil and one fourth of that of SF 6 gas. Law energy dissipation mainly due to low interruption time (due to small contact gap) and small arc length (this is also due to small contact gap). Because of this low arc energy dissipation, vacuum switchgear has negligible contact erosion and this gives it nearly maintenance free lifeGet price

Switchgear - Wikipedia

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levelsGet price
