摘　　要：随着直流配电系统的大量使用,直流配电系统的安全及相关产品的选用,日益引起工程设计人员的重视。从低压直流系统接地形式、基本特征、过流故障防护、接地故障防护,以及系统安全、相关产品选用及标准发展等方面对低压直流配电系统综合保护进行分析探讨。With the wide application of DC distribution system, its safety and the selection of relevant products have become increasingly significant to project designers. The paper conducts analyses and discussions on the integrated protection of DC distribution system in aspects of system safety, selection of relevant products, standard development, etc. based on the grounding mode, basic features, overcurrent fault protection, ground fault protection and other aspects of low-voltage DC system.
