摘要

在地铁牵引供电系统中，有必要在合闸馈电断路器之前检测线路状态并确认线路无短路。本文总结了现有线路检测的规则和原理，建立了地铁牵引供电系统和机车的仿真模型，研究了各种条件下线路检测的结果。针对目前线路测试中存在的问题，提出了新的解决方案。此外，通过计算测试电阻的温升，给出了测试电阻的选择方法。

Research on state monitoring method of subway DC traction power supply line

In the subway traction power supply system, it is necessary to detect the line state and confirm that there is no short circuit on the line before closing the feeder circuit breaker. In this paper, the existing rules and principles of line test are summarized, the simulation model of subway traction power supply system and locomotive is established, and the results of line test under various conditions are studied. Aiming at the problems existing in the current line test, a new solution is proposed. Furthermore, by calculating temperature rise of the test resistor, the selection method of the test resistor is given.
