摘要:
利用时域射线追踪算法,构建出简化开关柜模型并模拟局部放电,仿真分析局放电磁波到达不同检测点的时域特性. 由于多径传播,最短路径与其它路径存在到达时间差,通过叠加时间差相近路径的波形幅值,分析检测点时域波形混叠的原因,对比不同检测点的时域接收波形,分析波形畸变的原因. 研究结果为开关柜内局部放电的电磁波传播规律提供新方法,为后续优化超高频检测天线的安装摆放提供参考依据.
Abstract:
A simplified switchboard model is constructed by using the time-domain ray tracing algorithm,and partial discharge is simulated. The time-domain characteristics of partial discharge magnetic wave reaching different detection points are simulated and analyzed. Due to multipath propagation,there is a time difference between the shortest path and other paths,and the reason for the waveform aliasing of the detection point in the time domain is analyzed by superimposing the waveform amplitude of the path with a similar time difference. The time-domain received waveforms of different detection points are compared and the causes of waveform distortion are analyzed. The research results provide a new method for the electromagnetic wave propagation law of partial discharge in the switchgear,and provide a reference for the subsequent optimization of the installation and placement of UHF detection antennas.
