Description

Technical Field

[0002] It is well known that during rain, snow and freezing rain, the high-speed rail contact network is prone to ice formation, which causes the following hazards: poor contact of the high-speed rail pantograph, arcing, wear of the conductive surface, and inability to operate normally when the high-speed rail is powered off. Traditional deicing methods include mechanical deicing, which is to remove the ice layer on the contact network through mechanical cutting when the empty EMU is moving. This method is inefficient and causes damage to the contact network; manual deicing, which is done by manual knocking. This method requires power outage and grounding, which is time-consuming, labor-intensive, and unsafe; high-frequency and high-voltage excitation deicing, which applies high-frequency excitation current to generate heat inside the ice. This method requires power off operation, is inefficient, and will interfere with normal communications; the hot deicing method, which is to pre-embed heatable soft copper stranded wire in the original contact wire and heat the soft copper stranded wire by electrifying it. The hot deicing method is currently a more efficient solution, but it requires pre-embedded heatable soft copper stranded wire, which is only suitable for new and modified lines, and requires large investment and difficult maintenance.
