METHOD FOR THE PREVENTIVE DETECTION, AND THE DIAGNOSIS OF THE ORIGIN, OF CONTACT FAULTS BETWEEN AN ELECTRICITY SUPPLY LINE AND A CONDUCTING MEMBER MOVABLE ALONG SAID LINE

摘要

The invention relates to a method for the preventive detection, and the diagnosis of the origins, of contact faults between an electricity supply line (3) of an infrastructure and a fixed conducting member (2) of rolling stock movable along the line (3), electric arcs occurring in the event of a contact fault between the electricity supply line (3) and the mobile conducting member (2). The method includes steps of: detecting said electric arcs (40, 41); locating (42) the detected electric arcs; determining (43) the frequency of occurrence of the detected electric arcs; and deducing (44) the origin of the contact faults based on the location and the frequency of occurrence of said electric arcs, by determining the responsibility of the fixed infrastructure and the rolling stock in the cause of the fault, the method being implemented by computerised processing means.
