Abstract

1. Counter-contact system for a pantograph disconnector, having auxiliary busbars (183, 184) attached to the counter-contact (112-118), which busbars follow the pantograph contact tubes (68/70) over a defined switching-off distance in a switching-off operation, and having arcing contacts (146, 205) with assigned arc quenching device (174), which, controlled by the movement of the auxiliary busbars (183, 184) in the switching-off operation or upon bouncing during switching-on, disconnect a potential difference between the counter-contact (112-118) and the pantograph contact tubes (68/70), so that the occurrence of an arc between the pantograph contact tubes (68/70) and the counter-contact (112-118) is prevented, characterized in that the arcing contacts (146, 205) are bridged by a bypass route (300, 301, 302), into which is inserted at least one electric component (300) which forms a defined current path at least for displacement currents occurring in a switching operation.
