摘要
针对小电流接地选线装置选线正确率不高的问题,分析了小电流接地选线装置的工作原理和误差来源,结合实际运行经验,在设备选型、运行维护和装置的施工验收方面提出了提高小电流接地选线装置选线正确率的建议和措施。
In view of the poor accuracy of fault-line detector in small current grounded system,the principle and error source of the detector are analyzed.Based on practical operation experience,proposals covering detector type selection,operation,maintenance,installation and acceptance check are offered to improve the reliability of the detector.
