摘要:
基于高頻法檢測局部放電技術已經相對成熟,爲了現場檢測和對變壓器運行狀況做出准確診斷,文中提出了利用高頻法檢測分析放電信號傳播特性的方法。通過建立仿真模型確定了頻帶選擇範圍,並建立試驗平台,利用多傳感器同時測量和采集實時信號,對比研究了局部放電在變壓器內部傳播後以及在不同位置放電時高頻信號的頻譜特性。結果表明,高頻局部放電檢測法能夠對變壓器缺陷進行高效檢測且高頻信號變化規律明顯,爲實際的波形檢測提供了試驗依據。
Abstract:
The technology of detecting partial discharge based on high frequency method has been relatively mature. For on-site detection and accurate diagnosis of transformer operating condition, a method for detecting and analyzing the propagation characteristics of discharge signals is proposed by using the high frequency method. A simulation model is established to determine the band selection range, and a test platform is built to simultaneously measure and acquire of real-time signals using multiple sensors. Comparison of the spectral characteristics of the partial discharge high-frequency signals between after propagation inside the transformer and at different positions. The results show that the high-frequency partial discharge detection method can effectively detect transformer defects and has a clear variation rule of high-frequency signal, providing experimental basis for actual waveform detection.
