摘　　要：建立了直流系统两点接地等效模型,分析了不同工况下发生两点接地时直流系统绝缘对地电阻的分布情况,为判断直流系统是否发生绝缘接地提供了有效的理论判据。The two-point equivalent grounding efficiency model of DC system was established,and the distribution of insulation resistance to ground resistance of DC system when two-point grounding occurs under different working conditions was analyzed.This study provides an effective theoretical criterion for judging whether insulation grounding occurs in DC systems.

关 键 词：直流系统 绝缘电阻 两点接地 等效模型
