摘要

GIS具有优良的性能

被广泛应用于电力系统

在实际运行当中除了放电性故障所引起的事故外

也存在大量由机械故障所引起的事故

现行的检测手段多针对放电性故障

对机械性故障的检测与诊断较少。电压互感器（PT）是GIS设备中易于产生机械振动的设备

文中利用自行研制的GIS振动测试系统（GVTS）

对某110 kV变电站GIS的PT处进行了检测

并对测量结果进行了对比分析。结果表明

PT自身振动要强于其与相邻设备的连接处

PT中部振动最为强烈。文中的研究结果为现场检测GIS振动情况

对机械性故障的排查诊断提供了技术支持。

Abstract

GIS is widely used in power grid with its excellent performance. In the practical operation

besides the accidents caused by discharge faults

there are also a lot of accidents which are induced by mechanical faults.The existing GIS detection methods are mainly for discharge faults

but seldom for mechanical faults. Potential transformer（PT）is easy to generate mechanical vibration in GIS. In this study

the self-developed GIS vibration test system was applied to the measurement in the PT position in a 110 kV GIS

and contrastive analysis of the measurement results was performed. The results show that the vibration of PT itself is stronger than the vibration at the connection with adjacent device

and the strongest vibration is observed in the middle of PT. This research may provide data support for on-site testing of GIS vibration and diagnosis of mechanical faults.
