Abstract

The present invention relates to a high or medium voltage circuit breaker with abutting contacts, comprising, in an envelope (1) filled with gas having good dielectric properties, a first fixed abutting contact (8) linked to a first current terminal and a moving assembly including a first tube (2) capable of being displaced by an operating rod (3), the said first tube (2) being linked to a second current terminal and defining, with a second tube (4), a blowing volume (5) in which a fixed blowing piston (11) is arranged, this second tube (4) being extended by a blowing nozzle (6), the said circuit breaker also comprising a second semi-moving tubular abutting contact (9) sliding in the first tube (2) and pushed by its end opposite the first contact (8) by a first end of a helical spring (10) bearing by its second end on an annular shoulder (7) within the first tube (2). A temporary locking element, retractable by axial force, links the first tube (2) to the said envelope (1) in engagement position of the contacts (8, 9). <IMAGE>
