地铁直流牵引供电系统控制及保护装置的研究

摘要

地铁直流牵引供电系统控制及保护装置是直流系统的核心组件。控制及保护装置的准确性、快速性特点的是关系到地铁安全运营的重要前提。而且，保护装置故障录入功能更是为设备及线路故障排查和管理提供了更有力、更科学的依据。本文结合地铁建设及国内现行设备的主要特点，重点阐述地铁直流牵引供电系统控制及保护装置（DCP保护系列）的功能管理及直流系统短路试验的录波分析。%The control and protection devices of subway DC traction power supply system are the core component of DC system. The accuracy and rapidity of control and protection devices is the important premise of subway safety. The entry function of protection device fault provides more powerful and scientific basis for the troubleshooting and management of device and circuit. Combined with the main characteristics of subway construction and the current domestic equipment, this paper mainly expounds the function management (DCP protection series) of the control and protection devices of subway DC traction power supply system and the wave record analysis of short-circuit test of DC system.
