METHODS TO PREVENT ICING ON SYSTEMS OF CURRENT COLLECTION OF URBAN ELECTRIC TRANSPORT
Abstract
The harsh climate of the country imposes stringent requirements for all structures of equipment operated on rail transport. One of the adverse events is the formation of ice, fraught with increasing mechanical load on the structural elements of traction network, breach of electrical contact between the wire and the current collector, followed by arcing and burnout of trolley lines. Deicing on trolley lines and power lines is made by electrical, chemical and mechanical means. There are some negative aspects in the application of these methods: annealing danger, damage and deformation of wires, high energy consumption, low productivity, incomplete removal of ice. Many scientists deal with improvement of deicing methods with varying success throughout the time of electrification of railways. On the basis of performed tests the authors propose the use of a special durable coating to inhibit the formation of ice.
