METHOD FOR CATENARY WIRES HEATING

摘要

FIELD: electrical engineering.SUBSTANCE: between two adjacent transversal electric couplers two heating loops are made and these loops are connected in parallel to the heating unit. Each loop consists of a bearer cable, transversal electric coupler and contact wire; at that both loops are connected in parallel to the heating unit at which output current can be both direct or alternating; the heating unit is connected to the control unit which is connected to temperature control sensor for loop wires; at that heating zone is defined by the distance between two adjacent transversal electric couplers.EFFECT: provision of effective melting of ice at different sections of railway overhead cables.1 dwg
