his invention concerns a high-voltage circuit breaker that comprises, within a housing filled with dielectric gas, a first arcing contact (50) and a second arcing contact (70) that move in opposite directions from an open to a closed position and vice versa, the first contact (50) being fastened by means of a collar (54) to a tube (55) that slides within a support assembly (41) that is electrically connected to an electrical outlet (40). The said collar (54) is of insulating material. The first contact (50) is extended by a stem (51), coaxial with it, arranged on the opposite side to the second contact (70) and connected to a resistor (21, 22); on the stem (51) is a switching component (58) whereby the said stem (51) is directly connected electrically with the support assembly (41) during the closure.
La présente invention concerne un disjoncteur à haute tension comprenant dans une enveloppe remplie de gaz diélectrique un premier contact d'arc (50) et un second contact d'arc (70) mobiles dans des sens opposés d'une position d'ouverture à une position de fermeture et réciproquement, le premier contact (50) étant solidarisé par une bague (54) à un tube (55) coulissant dans une partie support (41) reliée électriquement à une prise de courant (40). Ladite bague (54) est en matériau isolant, le premier contact (50) est prolongé par une tige (51) coaxiale à ce contact (50), disposée du côté opposé au second contact (70) et connectée à une résistance (21, 22) et cette tige (51) porte un organe de commutation (58) agencé pour connecter électriquement directement ladite tige (51) et la partie support (41) en cours de fermeture.
