摘要
以半波电压较高的石英晶体为敏感材料 ,分析了光纤电压传感器全量程的温度特性 ,发现其与传感器所测电压值相关 :随着待测电压的从小往大增加 ,其输出温度变化的灵敏度逐渐由小变大。为了实现电压传感器全量程的温度补偿 ,必须获取两个关键的参数 :一为电压传感器在无外加电压作用下的温度输出响应参数 ;
The temperature characteristic of fiber optic sensor for high voltage within full range is analyzed. It is found that the sensitivity of the sensor to temperature depend on the magnitudes of voltage applied to the sensor. To realize temperature compensation over full range of the sensor, two key parameters must be acquired. One is the response of the sensor to temperature when voltage is zero; another is the response of the sensing material to temperature when voltage is applied.
