Temperature-compensated optical current measurement module and temperature-compensated optical current transformer

The invention discloses a temperature-compensated optical current measurement module and a temperature-compensated optical current transformer. The optical current measurement module comprises an incident optical fiber used for being connected with a light source, and an emergent optical fiber used for being connected with an optical signal demodulator. A first self-focusing lens, a polarizer, a magneto-optic glass, an analyzer and a second self-focusing lens are sequentially arranged between the incident optical fiber and the emergent optical fiber. The surface of the magneto-optic glass is provided with a temperature sensor used for measuring the internal temperature of the magneto-optic glass. According to the invention, the temperature sensor is arranged on the surface of a measurement optical element to measure the internal temperature of the magneto-optic glass and sense the temperature change of the magneto-optic glass, measured current sensed by the magneto-optic glass is demodulated from an emergent optical signal E2, and then the coefficient of the Faraday magnetic declination of the magneto-optic glass is corrected through temperature compensation, thereby realizing accurate current compensation measurement. The optical current measurement module has high structural stability and high measurement precision, and has the characteristics of large dynamic range of measurement, no magnetic saturation, wide measurement frequency band and wide temperature range.
