摘要
氧化锌避雷器随着运行时间的增长和避雷器本体通过雷电压次数的增多,避雷器内部结构将逐渐劣化甚至损坏,设备故障和频次将逐渐显现和增加,常规的检测方法和手段已无法满足安全运行要求,而红外热像带电监测氧化锌避雷器的测试技术,能够提高发现运行中氧化锌避雷器故障的准确性和及时性。
The internal structure of a zinc oxide lightning arrester is gradually degraded and even damaged owing to long-time operation of the arrester and increasing number of thunder voltage through the arrester.Faults in the arrester gradually increase.Conventional test methods and means can not meet the needs of safety operation.The infrared thermal imaging technology charging monitoring zinc oxide lightning arrester can determine fault in the arrester in operation accurately and in time.
