摘　　要：针对传统方法难以检测出干式空心电抗器的匝间绝缘缺陷的问题,在国标基础上设计了高压高频振荡波检测装置。在现场采用该装置测试了10kV并联电抗器,发现B相电抗器两个高频波的衰减速度和频率不一致,确定B相电抗器存在匝间绝缘故障,验证了其可靠性。As is difficult to detect the inter turn-to-turn insulation defects of dry-type air-core reactor,the high voltage and high frequency oscillation detection device was designed on the basis of national standard.When the device was used to test the 10kV shunt reactor,it was found that the attenuation speed of the two high frequency waves of the B phase reactor were inconformity,which identified that B phase reactor had an turn-to-turn insulation fault.The test results verified the reliability of the detection device.
