摘　　要：分析了某电厂直流系统出现直流电源监控装置故障及直流支路绝缘异常的原因,并提出了在直流电源监控装置失去作用的情况下,采用直接测量直流漏电传感器的输出电压来定位直流绝缘异常支路的办法,能够准确快速地定位绝缘异常支路,对处理类似的直流系统故障有一定的借鉴作用。This paper analyzes the causes of the fault of the monitoring device of the DC power source and the abnormal insulation of the branches in the DC system in a power plant.In addition,it suggests locating the branches with abnormal insulation by measuring the output voltage of the DC leakage sensor,which is accurate and rapid and can provide reference for solutions to similar faults of the DC system.
