分布电流无线监测在干式空心电抗器中的应用
摘要
电抗器线匝的分布电流不均会导致局部过热
从而降低绝缘性能
进行电抗器的分布电流监测工作有助于及时发现故障隐患。从工程现场出发
运用多只传感器实时监测电抗器每一层包封的分布电流数据

Abstract
Current distribution of reactor wire turns to local heat and thus decrease insulation performance
the distribution current monitoring of the reactor can be helpful for timely detection of faults. Starting from the project site
using multiple sensors to monitor current data of each layer of reactor and data is transmitted back to monitoring system in a wireless way. Experimental results show that the system can accurately measure distribution current change in reactor working environment
and it will provide an important theoretical basis and equipment support for real-time monitoring of dry type air core reactor in substation.
