摘要
针对某220kV变电站带电检测发现的110kV GIS存在局部放电信号情况,介绍特高频、超声局部放电检测方法,分析特高频局部放电检测、超声波局部放电检测以及放电源定位结果,解体检查结果验证了带电检测手段的有效性,并提出相关结论及建议。
Based on the abnormal signals detected on the 110 kV GIS in one substation,firstly,introduces the method of ultra-high frequency and ultrasonic testing.Secondly,analyzes the results of ultra-high frequency and ultrasonic testing,and the position of the power supply,finally,the disintegration test results verify the validity of the on-line detection method is.
