Abstract
The invention relates to a compressed gas high tension circuit breaker requiring low operating energy. The circuit breaker is located in a gas tight enclosure filled with gas having high dielectric power, and comprises a fixed assembly including a main contact and an arcing contact, and a moving assembly including a main contact and an arcing contact. The moving assembly includes a chamber (21) which is delimited by two tubular elements (20, 18A) each of which slides over two tubular surfaces (7, 8) of the fixed assembly, said chamber being in communication with the zone in which the arcing contacts separate via a plurality of holes (18B).
