Abstract
A reactor switch has a switching point which is arranged between a high-voltage reactor and a high-voltage line. When this switch is being switched off, the occurrence of arc-back oscillations with excessively high rate voltage changes is avoided in a simple and reliable manner. This is achieved in that the switching point is connected in parallel with a voltage-dependent resistor. This resistor, which preferably contains a metal oxide such as zinc oxide, has a current/voltage characteristic which limits the recurring voltage across the switching point in such a manner that the skewing rate of the voltage of a high-frequency arc-back oscillation occurring during an arc-back of the switching point always remains below a predetermined value.
