The invention discloses an optical fiber current transformer with temperature compensation. A depolarizer (5) is connected between a broad spectrum light source (4) and an optical splitter (6) of the optical fiber current transformer; a temperature acquiring unit (7) is connected between the optical splitter (6) and a computation compensating unit (1); a current acquiring unit (8) is connected between the optical splitter (6) and a data processing unit (2); the data processing unit (2) is connected on the computation compensating unit (1); and a modulation signal generating unit (3) is connected between the computation compensating unit (1) and the current acquiring unit (8). The optical fiber current transformer of the invention carries out synchronous processing on temperature and current in the computation compensating unit by using temperature-current curve relation in the computation compensating unit, and improves the accuracy of real-time detection and current output of the optical fiber current transformer of the invention.
