电力变压器局放检测方法较依赖于有线通信方式,在应对复杂多变的现场环境时,往往表现出较大的局限性,因此,文章提出了基于无线通信的电力变压器局放带电检测方法。基于无线通信采集电力变压器数据,提取带电检测中的信号特征,分析高频局放信号,实现电力变压器的局放带电检测。实验结果表明,该方法能够有效识别出电力变压器的局放幅值,并进行准确检测,检测效果较好。

The detection method of partial discharge in power transformer depends on wired communication,which often shows great limitations when dealing with complex and changeable field environment.Therefore,a method of live detection of partial discharge in power transformer based on wireless communication is proposed.Based on wireless communication,the data of power transformer is collected,the signal characteristics in live detection are extracted,and the high-frequency partial discharge signal is analyzed to realize the live detection of power transformer.The experimental results show that this method can effectively identify the partial discharge amplitude of power transformer and detect it accurately,and the detection effect is good.
