本文利用自製的高速信號擷取裝置，量測擷取頻率需求高的局部放電脈衝信號，並植基此自製裝置建立一監測系統，並於系統中加入基本的局部放電特徵擷取與雲端網路要素，達成信號檢測、特徵擷取、上傳雲端、圖表繪製等等功能。特徵擷取包含放電量、放電次數、放電相位等，並依據此繪製局部放電3D圖譜，網路部分包含自動擷取、資料傳輸、資料庫連線、雲端圖表繪製等。因系統中加入了雲端網路功能，可同時連接複數個擷取裝置，成為可線上自動檢測局部放電信號的多通道監測裝置。為了驗證自製高速資料擷取裝置的可行性，本研究利用數種量測案例，針對自製擷取裝置與市售的擷取裝置(NI工業電腦搭載PXI-5105擷取卡)進行信號擷取並比較分析，包含信號產生器、局部放電校正器、局部放電實驗模型，氣體絕緣開關(GIS)瑕疵模型等，將量測結果繪製成局部放電3D圖譜後，再計算每相位區間中的平均放電量與放電次數等特徵進行比較。分析結果顯示，本文所提出之多通道局部放電監測裝置，確具可行性。

In this thesis, a self-made high-speed data acquisition device is used to measure the partial discharge pulse signal with high frequency demand, and a monitoring system is built around the self-made device, and basic partial discharge feature extraction and cloud network elements are added to the system. It achieves the functions of signal detection, feature extraction, uploading the cloud, chart drawing, etc. The feature extraction includes pulse apparent charge, pulse repetition rate, phase angle of pulses, etc., and draws partial discharge 3D spectra according to this. The network part includes automatic extraction, data transmission, database connection, and cloud chart drawing, etc. Because the cloud network function is added to the system, multiple DAQ devices can be connected at the same time, and it becomes a multi-channel monitoring device that can automatically detect partial discharge signals on the line. In order to verify the reliability of the self-made high-speed data acquisition device, this thesis uses several measurement cases to signal both the self-made DAQ and the commercially available DAQ device (NI industrial computer equipped with PXI-5105 card). The analysis results are taken and compared, including signal generator, partial discharge calibrator, partial discharge experimental model, gas insulated switch (GIS) model, etc., and the measurement results are plotted as partial discharge 3D spectra, and then the average discharge and the number of discharges in each phase interval is calculated and compared. Under a stable signal source, the self-made DAQ device is similar to the commercially available device. The analysis results show that the multi-channel partial discharge monitoring device proposed in this thesis is indeed feasible.
