摘要
利用局部放电带电检测法对某220kV变电站10kV开关柜内局部放电故障进行检测,确定了缺陷类型及位置。经停电检查处理,验证了超声波及特高频检测法对开关柜内局部放电检测的准确性和有效性。
An internal partial discharge failure in a 10kV switchgear of a 220kV substation was detected and diagnosed using PD live detection method.The type and location of partial discharge were confirmed.Through the insepction with power outage,the accuracy and effectiveness of ultrasonic and UHF detection methods for the detection of internal partial discharge in switchgear were verified.
