伴隨(sui)著光(guang)電子技術(shu)的發展，熒光(guang)光(guang)纖溫度傳感器(qi)擁有體(ti)積小、耐高溫、耐超高壓、抗腐蝕、絕緣性能(neng)好、性價比高、不受應(ying)力振動(dong)干(gan)擾等(deng)諸多優勢(shi)，能(neng)夠突破(po)其(qi)他光(guang)纖測溫技術(shu)的局(ju)限，非常適合油浸(jin)式變壓器(qi)內部繞組(zu)熱點溫度的測量(liang)。

針對高等(deng)級變(bian)壓器設(she)計要求(qiu)(qiu)，設(she)計了耐受(shou)高等(deng)級電(dian)壓的光纖溫度探頭，并經過工頻耐壓及雷電(dian)沖擊試驗，完全達到變(bian)壓器內(nei)部高等(deng)級電(dian)壓安裝要求(qiu)(qiu)。
