FIELD: electrified transport. ^ SUBSTANCE: according to proposed method insulated extended conductor made of non-ferrous metal is laid along contact system to serve as antenna collecting energy of high-frequency oscillations of sparking between contact wire and current collector. Radio radiations are detected, filtered and limited by lower level. Obtained control signal is subjecting to analyzing as to number of peak values at preset time interval and space of time between peak values on basis of which separate arc bursts and interferences are recorded. Then analysis of number of arc bursts and time intervals between bursts is done, and with due account of ambient air temperature, causes of violation of current collecting are delimited. ^ EFFECT: possibility of continuous monitoring of quality of interaction of contact system and current collectors and revealing causes of violation of current collection. ^ 3 cl, 1 dwg |
