INTERRUPTER ASSEMBLY AND PORCELAIN COLUMN TYPE SULFUR HEXAFLUORIDE BREAKER

摘要

An interrupter assembly and porcelain column type sulfur hexafluoride breaker, the interrupter assembly comprising: more than two interrupter monomers (1, 2); each interrupter monomer comprises a moving support arranged at the head end and a static support arranged at the rear end, moving contacts (13, 23) being assembled on the moving support in a guiding and sliding mode, and static contacts (61, 62) coaxially opposite to the moving contacts being fixedly provided on the static support; the interrupter monomers are in end-to-end serial connection on the same axis, and the moving contacts of one interrupter monomer of each two adjacent interrupter monomers is in transmission connection to insulation connecting pieces (7, 71, 72) in transmission connection to the moving contacts of the other interrupter monomer, and the static support at the rear end of the former interrupter monomer of each two adjacent interrupter monomers is electrically connected to the moving support of the other interrupter monomer connected at the rear end of the interrupter monomer. Synchronous opening and closing can be carried out when the interrupter assembly is used, thus significantly improving the voltage grade borne by the interrupter of the breaker.
