摘要 介绍一起带电检测技术的成功应用案例。通过红外测温技术发现避雷器存在异常发热情况,并由避雷器泄漏电流试验发现故障相避雷器阻性分量超出正常值许多。结合红外测温和泄漏电流试验,初步判断避雷器过热缺陷为进水受潮所致。对问题避雷器进行停电并进行电气试验及解体,验证测试结论的正确性。 A successful application case of an online detection technology was introduced.The abnormal heat of the arrester was detected by infrared temperature measurement technology,and by detecting the leakage current of the arrester,it was found that the resistive component of the fault phase arrester was larger than the resistive component of the normal arrester.Combined with the infrared temperature measurement technology and the test of leakage current,it was initially determined that the overheating defect of the arrester was caused by the incoming moisture.At the same time,the power failure electrical test was conducted and disassembled,and the test conclusion was verified.
