Improved interrupter for direct-current applications with high currents or voltages of, for example for industry - and / or rails vehicle applications

摘要

The interrupter (1) for applications under high currents or voltages of, for a - / off of the high currents or interruption of these, with a high efficiency and rapid intervention times, for example, in industry - and / or rails vehicle applications, the interrupter (1) comprises: - a housing (10); - a base section (2) in the housing (10), wherein the base (2): - an activating mechanism (3) for switching means, comprising a retaining mechanism (20, 22) and a release mechanism (40); - a central contact portion (4) for the switching or interrupt, comprising fixed contacts (5) and movable contacts (6), and - an upper arc - quenching section (7), of the central contact portion (4) is covered for the switching or interrupt, characterized in that the arc - quenching section (7) with respect to the contact portion (4) is movable for the switching or interrupt, and with external polar expansions (60) is provided on both main sides of the interrupter (1) are coupled; further polar expansions (70) electrically connected to the external polar expansions (60) are coupled, and with the central contact portion (4) is interrupted for the switching or as a fixed parts of the interrupter (1) are connected.
