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
