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.
