摘要:
SF6分解物测试是判断SF6绝缘设备内部放电故障有效的方法。笔者在对一起直流分压器故障的分析 过?#35752;?#21457;现,SF6气体分析未能正确反?#36710;?#19968;次跳闸时内部已经出现的放电故障。后对直流分压器进行解 体发现,由于其内部电容器气室为单独密封设计,造成电容器内部放电故障产生的SF6分解物未能在直流分 压器取气口测出,以致不能正确判断设备健康状况。文中建议进行SF6分解物测试必须清楚了解设备内部 气路构成,并对在运的直流分压器故障诊断提出方案,对制造厂在直流分压器内部设计提出改进建议。
Abstract:
SF6 decomposition components test is an effective method to determine the internal discharge fault of SF6 insulation equipment. This paper proposes that the SF6 gas analysis failed to correctly reflect the discharge fault dur? ing the first trip in the analysis of the fault of DC voltage divider. After the disintegration of the DC voltage divider,it is found that the SF6 decomposition generated in the capacitor internal discharge could not be detected through the gas test tap of DC voltage divide due to internal condenser gas chamber for individual seal design,and it leads to fail? ure to correctly judge the health status of the device. It is suggested that the SF6 decomposition components test must be made to understand the internal gas path composition of the equipment,and the scheme of fault diagnosis of DC voltage divider in operation. Improvement suggestions are put forward for the internal design of the DC voltage divider.
