摘要

介绍了一起35 k V干式空心电抗器着火故障

通过外观检查以及返厂解体和试验

确定导线绝缘损坏引起匝间短路是造成此次故障的主要原因。针对此次故障暴露的问题

从原材料选用、制造工艺、带电检测和在线监测手段以及匝间短路保护技术等方面提出了预防性措施

对进一步提高设备安全运行水平具有一定的参考价值。

Abstract

In this paper

one fire fault of 35 k V air core drytype reactor is introduced. It is determined through appearance check

disassembly and testing at the manufacturer that the main cause is due to interturn short circuit because of insulation damage of wire. As for the fault problem exposed

the preventive measures are proposed in terms of raw material selection

manufacturing process

online detection and monitoring as well as inter-turn short circuit protection technology etc

which has a definite reference in improving safe operation level of the equipment.
