Abstract
To achieve the purposes of removing the signal detecting point to the most sensitive position and improve the anti-interference performance of the system, between fiber λ/4 wave plate and conductive optical fiber of original In-line optical fiber current transformer a Faraday rotator with 22.5° deflection angle is added on to form a passively demodulated all optical fiber current transformer. To promote the practical application of passively demodulated all optical fiber current transformer, according to the temperature characteristics of Faraday crystal for the preparation of Faraday rotator the influence of temperature characteristics of Faraday rotator on temperature stability of passively demodulated all optical fiber current transformer is analyzed theoretically, and for various types of Faraday crystals with different temperature characteristics the influence of temperature characteristics of Faraday rotator on temperature stability of system output is assessed by numerical calculation.关键词
