Abstract

1411797 Switchgear structures SIEMENS AG 2 Oct 1972 [30 Sept 1971] 45430/72 Heading H1N A switchgear structure comprises a switch 4 in a chamber 10 filled with insulating gas, e.g. SF 6 , and a spark gap 15 in a housing 12 externally of the chamber 10, the chamber and the housing being interconnected by valve means 20 which normally allows the flow of the insulating gas between the chamber and housing but prevents the flow when the spark gap breaks down. The response of the valve 20 may be flow or pressure dependent, or the valve may be operated by a coil 22 energized by a current transformer 23 in the earth connection of the housing 12. The spark gap may be that of a surge arrester having voltage dependent resistors 16 in a metal housing having a rupturable diaphragm 18. The structure may comprise a threephase metal-clad arrangement having switches 3, 4 to connect an overhead line 7 to duplicate bus-bars 1, 2.
