Abstract

The method involves using a DC rapid switching device with a switching unit (VS) and a quenching circuit parallel to the shaft section of the switching unit, consisting of a quenching capacitor (LK) connected in series with two antiparallel quenching thyristors (LT1,LT2) and an inductance (L). The switching process is initiated by a control command to open the metal contact of the switching unit at a certain time point. The first thyristor is fired at a defined time point dependent on the level and direction of the operating current. The second thyristor is fired at a time dependent on the quenching current's time profile. An independent claim is also included for rapid switching devices for quenching a DC current in a rectifier sub-mechanism for a railway current supply.
