METHOD FOR DETERMINING THE DEGREE OF DANGER AND VIOLATION OF CURRENT COLLECTION BY VOLUME Russian patent published in 2021 - IPC B60L5/00 B60L3/12 G01F13/00 

Abstract RU 2762807 C1

FIELD: quality control of the interaction of the overhead wire and pantographs of electric rolling stock.

SUBSTANCE: invention relates to quality control of the interaction of the overhead wire and pantographs of electric rolling stock. The method for determining the degree of danger of violation of current collection in terms of volume consists in the fact that radiation is received from arc, spark or other discharge or thermal processes, including overload sparks arising from violations of current collection. In this case, the duration of the violation occurred, the speed of the vehicle and the values ​​of the electric current flowing during the duration of the violation are measured, then the volume of the softened substance of the contact wire is calculated. The value of the obtained volume V* is compared with several predetermined thresholds Vj, where j is the level of danger of violation, taking the values ​​0, 1, ..., n. Wherein if Vj≤V*<Vj+1, then a decision is made about the hazard level j.

EFFECT: expanding the possibilities of diagnosing current collection violations, increasing its efficiency, reliability and reliability.
