Abstract: The present invention relates to a device for interrupting non-short circuit currents only, and in particular relates to a disconnector, more particularlyhigh voltage disconnector, or to an earthing switch, more particularly make-proof earthing switch, and further relates to a low voltage circuit breaker. The device comprises at least two contacts (10, 12) movable in relation to each other between a closed state and an open state and defining an arcing region(26),in which an arc (27) is generated during a current interrupting operation and in which an arc-quenching medium (17) comprising an organofluorine compound is present. According to the invention, a counter-arcing component (19) is allocated to the arcing region(26), the counter-arcing component (19) being designed for counteracting the generation of an arc (27) and/or being designed for supporting the extinction of an arc(27).

Abstract translation: 本发明涉及一种仅用于中断非短路电流的装置，特别涉及一种隔离开关，特别是高电压隔离开关或接地开关，特别是防爆接地开关，还涉及一种低电压 断路器。 该装置包括在闭合状态和打开状态之间可相对于彼此移动并限定电弧区域（26）的至少两个触头（10,12），其中在电流中断操作期间产生电弧（27），并且 其中存在包含有机氟化合物的灭弧介质（17）。 根据本发明，反弧部件（19）被分配给电弧区域（26），反电弧部件（19）被设计成用于抵消电弧（27）的产生和/或被设计成用于支撑 灭弧（27）。
