Circuit arrangement for automatic closure of an interrupted remote power supply loop

摘要

Circuit arrangement for automatic closure of an interrupted remote power supply loop upstream of an interruption point. In circuit arrangements of this type, relatively large switching elements are generally required, in particular relatively large series reactors in the shunt arm. In order to make do with relatively small switching elements, in particular in the shunt arm, a thyristor is used as a switch which can be turned off with a turn-off circuit containing a capacitor and a second thyristor. The circuit arrangement can be used in particular in intermediate repeater stations of remotely powered data transmission devices. IMAGE
