High-voltage switch with a main switch contact and an auxiliary switching device

摘要

High-voltage switch with a main switch contact (1) and an auxiliary switching device (7), the main switch contact (1) during the switching-on process, shortly before reaching its connected state, with the interposition of a turn-on resistance state (21) is bridged and the contact separation during the switching off in front of the contact separation of the main switch contact (1) is effected, whereby the movement of the auxiliary switching device (7) at least during the switching-off process is slowed down by means of a fluid, which in a with a first contact piece (11) of the auxiliary switching device connected first piston / cylinder assembly (15, 16) is moved, characterised in that a part of the first piston / cylinder assembly (15, 16) the first contact piece (11) with the interposition of a cushioning protection spring (13) carries.
