摘要

介绍了常规B1型地铁牵引供电系统与车辆主电路的匹配形式。通过地铁直流供电系统DDL保护误动案例的梳理，结合现场测试试验数据，分析了实际可能导致DDL保护误动的原因与过去DDL保护整定或存在的一些误区。对直流冲击特性与系统保护之间的配合关系提出了一些建议。

Abstract

This paper introduced the matching form between the conventional B1 metro traction power supply system and the main circuit of the vehicle. Through sorting out the maloperation cases of DDL protection in metro DC power supply system and combining with the field test data, the causes of the maloperation of DDL protection in practice and some errors in setting or existing DDL protection in the past were analyzed. Some suggestions on the coordination between DC impact characteristics and system protection were put forward.
