Vacuum switching tube for interrupting high DC currents

摘要

A vacuum switching tube in which two switching points are connected in series is proposed in order to interrupt high DC currents, especially for bath short-circuiters. This is implemented in that a relatively thin metal disc (7) is arranged between moving electrodes (1, 2) and is mounted in a resilient manner with respect to both electrodes. The invention is suitable for bath short-circuiters. IMAGE
