Abstract
A multifunctional capacitive-type sleeve with a vacuum arc-extinguishing chamber comprises a sleeve insulation core covered outside the vacuum arc-extinguishing chamber, wherein one ends of two connection terminals are respectively led out from the two ends of the sleeve insulation core, and the other ends of the two connection terminals can be contacted and separated in the vacuum arc-extinguishing chamber to switch on and off a circuit. The multifunctional capacitive-type sleeve with a vacuum arc-extinguishing chamber according to the present invention not only has the function of a sleeve, but also has the function of a disconnector, the sleeve insulation core is internally provided with a vacuum arc-extinguishing chamber to switch on and off the circuit, which can simplify structures of a high-voltage switch and a control cabinet, reduce the device volume, and decrease the device cost.
