背景技术Background technique

根据电力部门的相关要求，避雷器，例如35kV避雷器直流泄漏试验电流值的正常范围为(5-10)μA，当试验泄漏电流值达到50μA时为警戒值，高于50μA则表明试验不合格。According to the relevant requirements of the power department, the normal range of the DC leakage test current value of arresters, such as 35kV arresters, is (5-10) μA. When the test leakage current value reaches 50 μA, it is a warning value. If it is higher than 50 μA, it indicates that the test fails.

根据目前各变电站现状调查及分析，在进行35kV避雷器直流泄漏试验电流值过程中，由于被试设备周围设备安装密集，加压过程中，在周围导体表面也会产生泄漏电流，流经微安表后，直接造成了被试设备的试验泄漏电流值增大，并且往往因为试验引线离设备本体或构架距离太近，导致试验引线对设备放电，而使被试设备未达到试验标准值，经常导致试验终止。According to the current investigation and analysis of the current status of each substation, during the current value of the DC leakage test of the 35kV arrester, due to the dense installation of equipment around the equipment under test, leakage current will also be generated on the surface of the surrounding conductor during the pressurization process, flowing through the microampere meter Finally, it directly causes the test leakage current value of the tested equipment to increase, and often because the test lead is too close to the equipment body or frame, the test lead discharges the equipment, and the tested equipment does not reach the test standard value, often resulting in Trial terminated.
