    摘 要:針對傳統(tǒng)小型局部放電檢測設備功能單一、數(shù)據(jù)收集整理困難、大型局放檢測裝置操作復雜、不利于推廣的缺點,在分析比對主流的局放信號檢測方式后,設計開發(fā)了一種新型局部放電在線檢測儀器,能夠同時實現(xiàn)地電波(Transient Earth Voltage, TEV)、超聲和高頻電流三種檢測方法。檢測裝置以ZYNQ7020嵌入式系統(tǒng)為核心,外圍硬件電路部分實現(xiàn)信號采樣、外設操作、通信和信息存儲等功能,軟件部分完成信號降噪、數(shù)據(jù)處理、交互界面設計和故障診斷等工作。該局放檢測儀能夠滿足不同配電設備的在線監(jiān)測需求,為用戶提供全面、具體、多樣化的數(shù)據(jù)參考。

    Abstract: The traditional small-sized partial discharge detection instrument has the disadvantages of single function and data collection, and the large one is difficult for practice and hard-promoted. After the comparison of mainstream partial discharge detection methods, this paper designed a novel partial discharge online detection instrument, which could accomplish transient earth voltage (TEV), ultrasonic and high-frequency current detection. The instrument was cored with embedded system ZYNQ7020. The hardware circuit part realized functions such as signal sampling, peripheral operation, communication and information storage, and the software part completes signal denoising, data processing, interactive interface design and fault diagnosis etc. The partial discharge detector can meet online monitoring requirements of different distribution equipments, which provides comprehensive, specific and diverse data references for users.
    Key words: partial discharge; online detection; transient earth voltage; ultrasonic; high-frequency current
