双机牵引道岔控制电路是一种新型道岔控制电路,在动作重型道岔时较单机牵引控制电路更加安全、可靠。随着铁路运量的增加及列车速度的提高,多数站场正线都铺设了重型道岔,双机牵引电路也被越来越多的车站电气集中所采用,而在《铁道工程设计技术手册》里仅涉及到单机牵引控制电路,直接危及道岔可靠动作的一个主要因素——控制电缆芯线数却无处可查。我们结合工程设计,对双机牵引控制电路进行了分析比较、计算,编制了双机牵引各种类型道岔控制电路电缆芯线表。
Dual traction switch turnout control circuit is a new type of turnout control circuit, which is safer and more reliable than single traction control circuit when operating heavy duty turnout. With the increase of railway traffic volume and the increase of train speed, heavy-duty switchboards are laid on the main lines of most stations and dual-traction circuits are also used by more and more station electric concentrators. However, in “Railway Engineering Design Technology Manual” Only involved in a single traction control circuit, a direct threat to the reliability of turnout a major factor - the number of control cable cores are nowhere to be found. We combine the engineering design, analysis and comparison of the double traction control circuit, calculate, compiled a double traction cable control table various types of turnout cable.
