摘要

研究SF

组合电器局部放电检测与精确定位方法对提高设备检修效率具有重要意义。文中针对某些特殊情况下GIS局部放电的精确定位难题

首先研制了宽频带UHF（0.7

GHz）等角螺旋天线新型传感器

提出了基于多次加权平均的局部放电波形综合处理与时延定位算法

并建立了基于X光激励的局部放电缺陷辅助确认方法。以220 kV某站2号变高GIS间隔局部放电缺陷现场定位为例

相比于现有常用特高频定位方法

实践证明

Abstract

Study on SF

combination of electrical partial discharge detection and precise location is of great significanceto improve equipment maintenance efficiency. In this paper

some special cases GIS partial discharge pinpoint prob-lems

first

a new type of wideband UHF（0.7

GHz）equiangular spiral antenna sensor is developed

and compre-hensive treatment and delay times based on the weighted average of the positioning of the partial discharge waveformalgorithm are proposed

and a method for auxiliary confirmation of partial discharge defects based on X-ray excita-tion is established. Taking the spot location of GIS partial discharge defect in the 220 kV station

No. 2 transformer asan example

compared with the existing UHF location method

it has been proved that the integrated diagnosis meth-od proposed in this paper is more effective for the precise location of partial discharge in some special cases.
