The reactor switch is provided for switching on and off a reactor (2) in a multiphase electrical high-voltage network. It has switch poles (3) which are arranged phase-by-phase between the reactor (2) and a part of the network containing, a high-voltage line (1). These switch poles (3) in each case contain at least two series-connected switching chambers (11, 12; 13, 14) in parallel with which at least two series-connected varistors (15, 16; 18, 19) are connected. This reactor switch is intended to be capable of disconnecting short-circuits occurring between the reactor switch and the reactor (2) without problems. This is achieved in that the at least two varistors (15, 16, 17, 18, 19) and the at least two switching chambers (11, 12; 13, 14) are connected together in the form of a network on which the high-voltage network acts in terms of current and voltage and in which, in the event of restriking of some (11, 12) of the at least two switching chambers, the energy which is supplied to those varistors (17, 18, 19) which are connected in parallel with the switching chambers (13, 14) which are free of restrikes is less than in the case of a reactor switch having a network which is acted on in a corresponding manner, but in which each of the at least two switching chambers is bridged by at least one of the at least two varistors.
A reactor switch for switching a reactor on and off, wherein the reactor is arranged in a multi-phase electrical high-voltage network, the reactor switch including switch poles which are provided phase-by-phase between the reactor and a part of the network, each of the switch poles having at least four series-connected switching chambers and five varistors including two series connected first varistors, two series-connected second varistors and a third varistor,
A reactor switch for switching a reactor on and off, wherein the reactor is arranged in a multi-phase electrical high-voltage network, the reactor switch including switch poles which are provided phase-by-phase between the reactor and a part of the network, each of the switch poles having at least two series-connected switching chambers and at least two series-connected varistors connected directly in parallel across the at least two series-connected switches chambers, the two series-connected switching chambers being mounted on an insulator column and the two series-connected switching chambers being directly bridged by the at least two series-connected varistors.
