摘要

局部放电检测技术在不停电的情况下对开关柜设备绝缘状况进行诊断

是开关柜绝缘检测的重要手段。文中介绍了开关柜的暂态地电压（TEV）和超声波局部放电检测技术的原理

对两种方法在放电定位、降噪及模式识别技术等方面的研究进行了总结。基于检测理论与统计数据

给出两种方法对沿面和内部缺陷放电检测有效性差异的解释说明。鉴于TEV检测效果不理想的现状

建议现场检修工作适当减少TEV测试或以可靠性更高的方法代替

提高故障定位精度与诊断准确度。

Abstract

Partial discharge detection technology is a key method to switchgear insulation detection

which diagnoses the insulation condition of switchgear on-line.In this paper

the mechanism of TEV and ultrasonic detection methods applied to switchgear is investigated

research of technique like location

noise reduction and pattern recognition is summarized.With the combination of detection theory and statistical data

this paper explains the validity differences of two detection methods for detecting surface and internal defect model.In view of the unsatisfactory of TEV detection effect

it is recommended to reduce the TEV test on site or replace it with a more reliable method to improve fault location and diagnose accuracy.
