    • 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.
    • 电抗器开关用于在多相电气高压网络中接通和关闭电抗器(2)。 它具有在反应器(2)和包含高压线(1)的网络的一部分之间相位布置的开关极(3)。 这些开关极(3)在每种情况下都包含至少两个串联连接的开关室(11,12; 13,14)并联连接至少两个串联连接的变阻器(15,16; 18,19)。 该电抗器开关旨在能够在不存在问题的情况下断开在电抗器开关和电抗器(2)之间发生的短路。 这是通过以网络的形式将至少两个变阻器(15,16,17,18,19)和至少两个开关室(11,12; 13,14)连接在一起的,其中高 - 电压网络根据电流和电压起作用,并且在所述至少两个开关室的一些(11,12)的再起弧的情况下,提供给所述压敏电阻器(17,18,19)的能量 与不具有重新起动的开关室(13,14)并联连接的电抗器小于在具有以相应方式作用的网络的电抗器开关的情况下,但是其中至少两个开关 室由至少两个变阻器中的至少一个桥接。

    • A switching apparatus includes a grounded, insulating gas-filled housing, the housing having a housing wall, and a power circuit-breaker disposed in the housing. The apparatus further includes a current connection for a first busbar, a current connection for a second busbar, and a current connection for a load outgoer. The apparatus further includes a grounding switch disposed in the housing, the grounding switch being connected between the power circuit-breaker and the current connection for the load outgoer, and a busbar disconnector, the busbar disconnector being connected between the current connection of the first busbar and the power circuit-breaker and between the current connection of the second busbar and the power circuit-breaker. An outwardly extended, first tubular flange arrangement is attached over a first opening in the housing wall, and an outwardly extended, second tubular flange arrangement is attached over a second opening in the housing wall. A first outdoor bushing is provided, the first outdoor bushing being fastened to the first tubular flange attachment, the current connection for the first busbar extending through the first outdoor bushing. A second outdoor bushing is provided, the second outdoor bushing being fastened to the second tubular flange attachment, the current connection for the second busbar extending through the second outdoor bushing. The busbar disconnector is movable between at least three positions, the busbar disconnector having a first and a second fixed contact and a movable contact arrangement, the movable contact arrangement interacting with the first and second fixed contacts and being electrically conductively connected to the power circuit-breaker, the first fixed contact defining an end of the current connection of the first busbar and being disposed in the housing, and the second fixed contact defining an end of the current connection of the second busbar and being disposed in the housing.
