電壓互感器熒光光纖測溫解決方案

熒光光纖測溫儀能夠實時監測密閉氣室中分壓器的溫度,從而能夠檢測到直流電壓互感器內部的溫度 ;并配合均勻固定在分壓器上的熒光光纖溫度傳感器,能夠全面可靠的進行溫度監測,以及整個溫度監測采用光學信號傳輸,因此不受高電壓、強電磁干擾的影響,能夠準確的判斷檢測到的溫度是否超出了分壓器的正常工作溫度,保障直流電壓互感器的安全運行 ;熒光光纖溫度傳感器將感應到的溫度轉化為光信號經轉接光纖傳遞到熒光光纖測溫儀,熒光光纖測溫儀對溫度光信號進行調制和解調,再傳輸到光纖轉換器中進行光電轉換,光纖轉換器再將轉換后的溫度電信號傳輸到 PC 機上,在 PC 機上顯示出直流電壓互感器內部各熒光光纖溫度傳感器測量的溫度。熒光光纖測溫系統不僅能夠用于對特高壓直流電壓互感器進行監測,而且還能夠用于對采用熱模擬法得到的內部溫度曲線進行驗證。

電壓互感器測溫

熒光光纖測溫儀能夠實時檢測直流電壓互感器內部的溫度,判斷此溫度是否超出了電阻、電容的正常工作溫度,保障直流電壓互感器安全運行。

可以用于特高壓直流電壓互感器實驗階段的內部溫度的測量,對采用熱模擬法得到的內部溫度曲線進行驗證,也可長期用于特高壓工程,對直流電壓互感器的安全運行進行監測。監測數值準確可靠,具有耐高溫耐SF6環境的特性,并且不受高電壓、強電磁干擾的影響,準確的反映直流電壓互感器內部的溫度。
