Claim 1
Independent Claim
205 words
In a high-voltage switching system, of the type including a switching housing containing a gaseous insulating medium, a voltage overload arrester housing also containing a gaseous insulating medium, a voltage overload arrester disposed in the arrester housing, and a monitoring device, coupled between a ground terminal of the overload arrester and ground potential, for monitoring the response of the arrester and providing a measure of the magnitude of the discharge currents flowing therethrough, the improvement comprising an electrically conductive feedthrough coupling member, coupled to said ground terminal of said arrester and to said monitoring device, and extending outwardly through said arrester housing, said feedthrough coupling member comprising an electrical conductor coupled to said ground terminal of said overload arrester, a body member constructed of electrical insulation material and including an elongated, axially disposed aperture in which said electrical conductor is disposed, and gas-tight sealing means for preventing the escape of said gaseous insulating medium contained in said arrester housing therefrom, and said monitoring device being coupled between ground potential and said feedthrough coupling member and being disposed on the outside surface of said overload arrester housing, said feedthrough coupling member and said monitoring device forming an integral structural unit extending outwardly through said arrester housing.
Claim 2
Dependent Claim
205 words
In a high-voltage switching system, of the type including a switching housing containing a gaseous insulating medium, a voltage overload arrester housing also containing a gaseous insulating medium, a voltage overload arrester disposed in the arrester housing, and a monitoring device, coupled between a ground terminal of the overload arrester and ground potential, for monitoring the response of the arrester and providing a measure of the magnitude of the discharge currents flowing therethrough, the improvement comprising an electrically conductive feedthrough coupling member, coupled to said ground terminal of said arrester and to said monitoring device, and extending outwardly through said arrester housing, said feedthrough coupling member comprising an electrical conductor coupled to said ground terminal of said overload arrester, a body member constructed of electrical insulation material and including an elongated, axially disposed aperture in which said electrical conductor is disposed, and gas-tight sealing means for preventing the escape of said gaseous insulating medium contained in said arrester housing therefrom, and said monitoring device being coupled between ground potential and said feedthrough coupling member and being disposed on the outside surface of said overload arrester housing, said feedthrough coupling member and said monitoring device forming an integral structural unit extending outwardly through said arrester housing.
Claim 3
Dependent Claim
32 words
