Abstract
A circuit breaker unit has first and second arcing contact pieces. A breaker gap is formed between the two arcing contact pieces. A switching gas channel leads to the breaker gap and guides the switching gas to a switching gas outlet opening of the circuit breaker unit. The switching gas channel is formed with first and second pipe sections that overlap each other at least in sections and have discharge openings in their cover surfaces. Continuous discharge openings in the first and in the second pipe sections are axially offset in relation to each other.
Claims6
A circuit breaker unit assembly, comprising:
- a first arcing contact piece and a second arcing contact piece and a breaker gap between said first and second arcing pieces;
- a switching gas channel leading from said breaker gap to a switching gas outlet opening of the circuit breaker unit;
- first and second pipe sections delimiting said switching gas channel, at least in portions thereof, said first and second pipe sections overlapping one another in an axial direction within an overlap segment;
- each of said first and second pipe sections having lateral surfaces formed with discharge openings, and wherein unobstructed discharge openings in said first and second pipe sections are axially offset relative to one another;
- and
- fitting bodies respectively encompassing said pipe sections at end faces thereof, with said fitting bodies protruding from opposite directions into said overlap segment such that said fitting bodies end at a common path running around the axial direction.
