Impulse release reacting upon the advanced wear of a sliding carbon contact of current collectors forming part of sliding-contact lines

摘要

In sliding-contact line systems there is the requirement to change the sliding carbon contact (211) wear component forming part of the current collectors (21) with such promptness that an unmonitored failure of loads supplied via the current collectors (21) is avoided. For this purpose, it is proposed to assign a mechanical pulse trigger (31) to the sliding-contact line (11, 12), which trigger is acted upon by the corresponding current collector (21) in the case of advanced wear of the sliding carbon contact (211) and triggers an electric pulse which leads to an indication of the requirement for the sliding carbon contact (211) to be changed.
