地铁纵向联络隔离开关联锁的研究与实现

Research and Implementation of the Interlock Function of Vertical Link Isolating Switch in Metro

论述地铁直流牵引供电系统中纵向联络隔离开关的基本闭锁逻辑,对用硬接线和数字化通信方法实现联锁功能进行分析和比较,重点阐述用数字化通信方式实现联锁的基本原理和实现过程,说明该方法的技术特点、功能和设计要点。

This paper introduces the basic atresia logic of the vertical link isolating switch used in subway DC traction power supply system. Methods by using bard-wire connection and by using digital communication to realize interlock functions are illustrated and compared. The basic principles and implementation process of using digital communication to realize interlock function are specially demonstrated, and the technical characteristics, functions and design features of this method are analysed.
