Abstract

1,157,812. Gas-filled switches. INSTITUT PRUFFELD FUR ELEKTRISCHE HOCHLEISTUNGSTECHNIK. 6 July, 1966, No. 30263/66. Heading H1N. A high voltage switch immersed in SF 6 has two main fixed contacts 2b, 2c with a main bridging contact 2a and two fixed arcing contacts 3b, 4b with co-operating fixed contacts 3a, 4a, the two pairs of arcing contacts 3, 4 being in series with a coil 7 across the main contacts 2 and the arcing contacts (Fig. 2) being elliptical so as to provide elliptical gaps 10 around which the arcs L are caused to move by the field of the coil 7. All three movable contacts 2a, 3a, 4a are attached to an insulating sleeve 5 on a shaft coupled to operating mechanism through a bellows seal 16. The fixed arcing contacts 3b, 4b are in the form of rings with resiliently mounted contact making parts 3c and are mounted inside an insulating sleeve 6 about which is wound coil 7.
