摘要
目前超特高压避雷器节数较多、结构复杂,现有的带电检测和在线监测技术已经无法有效判断出避雷器的内部电阻片劣化缺陷的问题。研究能够长期放置在避雷器内部测量探头的结构、取电、温湿度测量以及无线传输方法,通过测量各节点的温湿度和电流数据,并通过无线方式发送给后台,更有效地判断超特高压避雷器内部缺陷。内部测量避雷器节点温湿度的方式,能够提高超特高压避雷器的内部缺陷及缺陷位置的诊断能力,实现超特高压避雷器内部故障有效识别和定位。
At present,the number of super-high voltage lightning arresters is large and the structure is complicated.The existing power detection and online monitoring technology can no longer effectively judge the problem of deterioration defects of the internal resistance of the mineslite.The structure,electricity removal,temperature and humidity measurement,and wireless transmission methods of the probe in the lapeller is studied.By measure the temperature and humidity and current data of each node internal defects.The internal measurement of the temperature and humidity of the minefarer nodes can improve the diagnostic ability of the internal defects and position of the super-high-voltage lightning mock,and to achieve effective identification and positioning of the internal failure of the super-high-voltage lightning moatter.
