摘要
Abstract
This paper proposed an active insulation detection method into which low-frequency AC signal was injected. And the method was partitioned into two detection stages:fault detection and insulation resistance calculation.In the fault detection stage,by measuring the “measurement resistance”voltage and then calculating the positive-negative parallel resist-ance value,the insulation resistance fault status of the insulation resistance can be determined.In the insulation resistance calculation stage,by disconnecting the load circuit and the AC signal source and then respectively connecting two resistors in parallel with positive and negative insulation resistance,two resistors terminal voltage can be measured and the positive and negative insulation resistance values can be calculated.Simulation results show that the failure rate of false positives is less than 2.1 5% of fault detection,and it can basically achieve a function of real-time detection in the insulation resistance detec-tion by injecting the low-frequency AC signal.关键词
