METHOD OF EXTINGUISHING THE ARC IN HIGH-VOLTAGE HIGH-POWER CIRCUIT BREAKERS

摘要

1. A method of extinguishing the arc in high voltage high power circuit breakers comprising the following steps : (A) momentarily generating an electrically highly conductive high pressure plasma by means of a free-floating piston (2) in a compression tube (3), (B) opening the switch contacts and taking up the current by the high pressure plasma, and (C) extinguishing the switching arc in relieving the high pressure plasma by reversal of the direction of movement of the freely floating piston (2) (Figs. 1, 3).
