在直流牵引供电系统中，馈线断路器在合闸前及故障跳闸后重合闸前，需经过线路检
测回路对线路进行非短路确认后才能合闸。本文阐述了线路检测及其与自动重合闸配合的原理，并介绍了直流牵引馈线的保护配置。根据运营实例，说明了线路检测在馈线保护中的作用，对其在运行中暴露出的整定及与自动重合闸配合问题进行了分析，并提出了解决方案。

Abstract: In DC traction power supply system, after line detection can not found short circuit, feeder circuit breaker can be closed. The principle of line detection with automatic re-closing was discussed and DC traction feeder relay protection is introduced. According to representative example, the application of line detection with automatic re-closing and problems, which was found in work, was analyzed, and a solutions was put forward.
