光纖測溫系統(tǒng)是一種利用光在光纖中傳播的某種特性,實現(xiàn)實時測量空間溫度場分布的新技術,對光纖沿線場所的溫度進行分布式連續(xù)檢測,光纖本身就是溫度傳感器。該技
術特別適用于電氣設備的溫度檢測,并能和消防報警系統(tǒng)配合使用,對電力系統(tǒng)一次帶電設備進行在線溫度檢測,它將給變電站的“五遙”監(jiān)控系統(tǒng)充實新的內(nèi)容,在發(fā)電廠、變電站中有廣闊的應用前景。

【Abstract】　Optical fiber temperature sensor system is a newly developed technique for the mea2surement of spatial temperature dist ribution. It can be used to monitor temperature along an opti2 cal fiber of some kilometers. The optical fiber it self is both the sensing element s and the signal t ransmission medium. Because of it s int rinsic advantages , this technique is especially suitable for the temperature monitoring of elect rical power facilities. When combined with other fire protec2 tion techniques , dist ributed optical fiber temperature sensor system will be widely used in the state monitoring of elect rical facilities in elect rical power plant , substations and so forth.
