| 中文摘要 | 研究了基于晶体电致旋光效应的光学电压传感器,电压传感元件采用了国产钼酸铅(PbMoO4)晶体。光学电压传感头仅由两块棱镜偏振器和一块钼酸铅晶体组成。实验结果表明此电压传感器具有较大的线性测量范围,例如对50-5000V工频电压测量的非线性误差低于0.2%;当测量100kHz的高频电压并利用锁相放大器检测传感信号时,最小可测量电压幅值为0.5V。此外,实验测量了所用钼酸铅晶体在635nm光波长及工频电压作用时的电致旋光系数,其数值为1.03pm/V。; "Based on electrogyratory effect,an optical voltage sensor is experimentally investigated by using an electrogyratory crystal as voltage-sensing element.The optical sensing unit only consists of two prism polarizers and a block of lead molybdate crystal.The 50 Hz ac voltage from 50 V to 5 000 V was measured with nonlinear error less than 0.2%.The ac voltage within 10 V and with frequency of 100 kHz was also measured by use of the voltage sensor associated with a lock-in amplifier,and the minimum measurable voltage was 0.5 V." In addition,the electrogyratory coefficient of the used lead molybdate crystal was also measured,and its value was 1.03 pm/V for the light wavelength of 635 nm and 50 Hz ac modulating voltage. |
