磁光薄膜电流传感器

Design of Magneto-Optic Thin Film Current Sensor

磁光薄膜电流传感器 ,是基于磁致旋光介质在外磁场的作用下 ,对偏振光振动面的旋光原理、光导纤维对高压电场的隔离特性而设计的一种新型电流传感器。它可用于低压、高压和超高压配电网中 ,对直流。

With applied magnetic fields,the vibration plane of the linearly polarized light will be rotated when it goes through a magneto-rotation medium,and high-tension electric field can be segregated by light transmitting fiber.Based on these properties,designed a new kind of current sensor called magneto-optic thin film current sensor.This device is available for power transmission network in low pressure,high pressure,and ultrahigh pressure and has ability of real time monitoring and controlling to direct or alternating current.
