Title:
GAS-INSULATED, METAL-CLAD, SINGLE-PHASE OR POLYPHASE SWITCHGEAR UNIT
Document Type and Number:
WIPO Patent Application WO/2011/110298
Kind Code:
A3
Abstract:
The invention relates to a gas-insulated, metal-clad, single-phase or polyphase high-voltage switchgear unit, comprising a long cable, which has a tubular cladding and a number of internal conductors (16, 17; 32) corresponding to the number of phases, and a compensation device (11) for offsetting temperature-dependent changes in length of the cable. The cladding of the cable part of the compensation device (11) has a first tubular cladding section (12, 42) on which a connector (13) extending perpendicular thereto is integrally formed for connecting a further cable. A metal bellows (19, 20; 40, 41) is fastened to each end of the tubular cladding section (12, 42), and the free ends of said metal bellows are fixed spaced apart by means of a holder (25, 49). The internal conductor in the tubular cladding portion (12, 42) is electrically conductively connected to the internal conductor (17, 23) which extends perpendicular thereto and is associated with the connectors (13) via a sliding contact connection (18).
