| description | The utility model relates to an all-fiber current transformer, the all-fiber current transformer comprises a sensing ring and a signal processing circuit used for photoelectric conversion and finally outputting an acquisition signal, the sensing ring comprises a shell and an optical fiber arranged in the shell, and the signal processing circuit is connected with a temperature sensor in an acquisition manner; the temperature sensor is arranged in the same temperature environment of the sensing ring; and a cover body made of a temperature conducting material is also arranged around the temperature sensor. When the all-fiber current transformer is used, the temperature is measured beside the heat conduction material in the same temperature environment of the sensing ring, and error compensation is carried out on the all-fiber current transformer by using the measured temperature. According to the utility model, the error of the all-fiber current transformer measuring device in the whole environment temperature r |
