Abstract

The quenching gas flow is produced by a compression device during switching off. The quenching gas in the circuit breaker is compressed in a compression chamber (2) by the face (1a) of a differential piston (1). The high compression causes the quenching gas to flow in the direction of the light arc. At least part of the quenching gas, heated by the light arc, is expanded in a quenching gas expansion chamber (6). Thus the other face (1b) of the piston ana at least a part of the chamber boundary (6a) are moved apart. This fraction of the quenching gas is drawn off towards the end of the switching off from the expansion chamber to the quenching chamber of the circuit breaker surrounding the compression and expansion chambers.

Description

Emellett különösen a sűrítőtér, a kisnyomású áramlási közegszakaszba jutó növekvő nyomású oltóközeget vezető járatrendszer és a tágulótér szerkezeti kialakítása a rajzon csupán példaképpen bemutatottól eltérő is lehet, így például az oltóközeget sűrítő dugattyú egy az érintkezőelemektől és a fúvókatesttől különválasztott sűrítőtérben elhelyezett és az említett elemekhez viszonyítva aszimmetrikus elrendezésű is lehet. Ugyanakkor a tágulótér is függetleníthető a fúvókatesttől, és a forró gázt a tágulótérbe bevezető járatrendszer is eltérhet a rajzon bemutatottól. Lényeges azonban, hogy a nyomásemelkedés formájában kinyert hőenergiát a tágulótérbe a lehető legkisebb veszteségekkel bíró járatrendszerrel vezessük be.In addition, in particular, the design of the compression chamber, the passageway leading to the high pressure fluid extending into the low pressure flow section and the expansion space may only be different from the example shown in the drawing, e.g. can also be arranged. However, the expansion space may be independent of the nozzle body, and the passage system for introducing hot gas into the expansion space may differ from that shown in the drawing. However, it is important that the heat energy obtained in the form of a pressure increase is introduced into the expansion space with a passage system with the least possible losses.
