Research on Ice Melting and Snow Removal Technology for Contact Rail
There are a large number of ground and elevated lines in urban rail transit lines.In winter,especially un-der icy and snowy weather,the contact rails of power supply are covered with ice and snow under harsh environ-mental temperature and humidity.In severe cases,it cause damage to the current collector and contact rails and en-danger the safety of train operation.Therefore,the technology of melting ice and removing snow for contact rails is a key issue in the operation of rail transit systems.Focusing on the issue of ice and snow accumulation on contact rails,the main ice melting and snow removal technologies at home and abroad are analyzed,explained the princi-ples of various methods,and compared and analyzed the advantages and disadvantages of different technologies in this study.Based on electromagnetic induction heating principle,a new type of composite ice melting and snow re-moval scheme are introduced.The composition,working principle,characteristics,and effects of this scheme are e-laborated,and the development trend in the future is forecasted.
