| Abstract: | Keeping railroad switch in good conditions is the precondition of train operation safety,punctuality,high density of railway transportation. The railroad switch snow-melting in winter is an urge problem for railway transportation authority. Electric heating is the main snow-melting method. The installation method of electric heating units of TYDR-A ,which is developed by the Signaling and Communication Research Institute,China Academy of Railway Sciences,is introduced and compared with other types. The stre... |
