摘要
直流系统的绝缘水平直接影响到整个系统的安全稳定运行。结合实际运行经验,针对大型变电站直流绝缘巡检系统中存在的整体绝缘降低、绝缘均等下降的动作死区及"泄漏电流法"的固有缺陷等问题,提出相应的改进措施和设计方案。
The security and stability of power system operation is affected directly by the insulation level of DC system.Based on the practical operation experiences,this paper proposes the improvement measures and design scheme to solve the inherent problems in DC insulation inspection system of large-scale substation,such as the overall insulation reduction,dead zone of insulation equal decline,and leakage current method.
