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.

Claim (Index 7):
The multifunctional capacitive-type sleeve with a vacuum arc-extinguishing chamber according to  claim 4 , wherein the two capacitive screen groups in the sleeve insulation core respectively form the main capacitor, the voltage-dividing capacitor and the shielding capacitor, the main capacitor and the voltage-dividing capacitor are connected in series to form the capacitive voltage divider for providing voltage signal output, and the shielding capacitor plays a role of shielding and protecting; wherein both the two ends of the main capacitor after in series connection with the voltage-dividing capacitor of one capacitive screen group, and the two ends of the shielding capacitor of one capacitive screen group are respectively connected to the connection terminal at end of the multifunctional capacitive-type sleeve and an earth potential; both the two ends of the main capacitor after in series connection with the a voltage-dividing capacitor of the other capacitive screen group, and the two ends of the shielding capacitor of the other capacitive screen group are respectively connected to the connection terminal at the other end of the multifunctional capacitive-type sleeve and the earth potential; and a current transformer secondary coil is sleeved in the scope of the earthing screen of the two capacitive screen groups outside the the sleeve insulation core.
