摘　　要：由于综合铝护套信号电缆四线组工作电容的存在,当远程提速道岔控制电缆长度达到2.3km以上时,如果道岔控制电缆设计使用不合理,一旦室外电缆盒内X1线发生断线,在四线组工作电容的干扰下,室内表示继电器就存在不可靠落下的问题。为此,研究远程提速道岔控制电缆的使用规则,避免类似问题的发生。Due to the existence of mutual capacitance of the signal quad cable within integrated a luminum sheath, the indoor indication relay may drop away unreliably under the interference from the mutual capacitance of the signal cable quad, once the X1 line in the outdoor cable box breaks if the control cable of the switch cannot be design for reasonable use in the case that the length of the control cable is large than 2.3km. Therefore, the rules of using the control cable for the remote speed increasing switch are studied to avoid the occurrence of such a problem.
