摘 要：為提高變壓器在線監(jiān)測裝置的可靠性及監(jiān)測數(shù)據(jù)的準(zhǔn)確性，基于國網(wǎng)公司調(diào)研材料，統(tǒng)計(jì)分析了變壓器設(shè)備狀態(tài)監(jiān)測技術(shù)的應(yīng)用情況和狀態(tài)監(jiān)測裝置的可靠性與有效性，并給出了總體配置原則及優(yōu)選評(píng)價(jià)方法，提出變壓器在線監(jiān)測項(xiàng)目推薦安裝油色譜監(jiān)測裝置和鐵芯接地電流監(jiān)測裝置，采用局部放電帶電檢測代替在線監(jiān)測等建議。
關(guān)鍵詞：變壓器；在線監(jiān)測；故障；油色譜分析；鐵芯接地電流；局部放電

Abstract: In order to raise the reliability and correctness of monitoring data for transformer online monitoring device, this paper carried out statistical analysis of transformer equipment state monitoring technology’s application situations based on state grid company investigation and study materials, as well as state monitoring device’s reliability and validity. This paper gave the total disposition principle and the preferred selection and evaluation method. The transformer online monitoring project was raised to recommend installing oil spectrum monitoring device and iron core grounding current monitoring device with partial discharge line detection instead of online monitoring etc.
Key words: transformer; online monitoring; fault; dissolved gas analysis; iron core grounding current; partial discharge
