摘要

介绍了某500 kV变电站一起500 kV瓷柱式断路器分闸故障

通过X射线数字成像技术对缺陷部位进行了准确定位

并解体分析发现带动灭弧室触头运动的水平驱动销轴断裂是故障发生的直接原因。更换了故障设备灭弧室

对驱动杆装配零部件进行了化学、机械力学、电气等相关试验

从材质、零配件尺寸和非常规外力等方面分析并最终得出故障发生的根本原因。最后根据诊断分析结果提出了相应的防范措施

同时对同批次产品进行了X射线专项隐患检查。

Abstract

An opening fault of a 500 kV SF6 porcelain column circuit breaker is analyzed. The defect in circuit breaker is located by X-ray digital radiography（XDR）. Disassembly inspection of arc quenching chamber reveals that the fault is directly due to fracture of the horizontal drive shaft that drives the breaker contacts. Subsequently

this arc quenching chamber of the faulty equipment is replaced. And chemical

mechanical and electrical tests are conducted for the driving rod’s assembly parts in terms of material

part size and non-conventional force to eventually find the ultimate causes of the fault. In addition

some countermeasures are suggested

and the same batch of products is tested by XDR.
