Abstract (en)
[origin: EP0701264A1] The arc-extinguishing circuit breaker comprises an envelope (1) filled with dielectric gas under pressure. The envelope contains two arc contacts (3A,7A) cooperating together, and includes a mobile contract assembly formed by a first tube (7) and a second coaxial tube (8) defining an extinguishing chamber (17). A compression chamber (18) communicates with the extinction chamber (17) and is closed by a semi-mobile pressure piston wall (11). The piston (11) consists of two parts (12,13) comprising first and second pressure walls (12A,13A), the second being of smaller surface area than the first.
