【摘要】：全光纖電流互感器(FOCT)比差隨溫度漂移會引起FOCT準確度下降。為解決這一問題,首先闡述了溫度波動對全光纖電流互感器影響的機理,并依據該機理分別建立了溫度對線性雙折射影響的數(shù)學模型和線性雙折射對全光纖電流互感器影響的數(shù)學模型。進而推導出溫度對全光纖電流互感器影響的數(shù)學模型,通過該數(shù)學模型量化研究了FOCT比差隨溫度漂移問題。得到了FOCT溫度特性為:在試驗溫度范圍即10~60℃內,比差與線性雙折射相位差和溫度都近似呈線性關系。進一步試驗驗證了FOCT比差與溫度的近似線性關系,且基于該關系對互感器進行溫度補償,可使其精度滿足0.2級的要求。
[Abstract]:The FOCT accuracy will be decreased due to the temperature drift of the Foct ratio of all fiber current transformers. In order to solve this problem, the mechanism of the effect of temperature fluctuation on all-fiber current transformer is discussed. According to this mechanism, the mathematical models of the effect of temperature on linear birefringence and the influence of linear birefringence on all-fiber current transformer are established respectively. Furthermore, the mathematical model of the effect of temperature on all-fiber current transformer is derived, and the temperature drift problem of FOCT ratio is quantitatively studied by the mathematical model. The temperature characteristics of FOCT are as follows: in the range of test temperature, namely 1060 鈩，
