|
摘要
基于Pockels效应,选取具有较高电光系数的LiNbO3晶体,采用横向调制方式,设计制作了光学电压传感器,以Z向通光消除自然双折射对传感器响应特性的影响。分别在实验室和户外搭建试验平台测试传感器的各项特性,并与非接触感应单元组合使用,挂网试运行于南方电网兴仁±500kV换流站进行过电压在线监测,传感器的实验结果及试运行状态表明该传感器具有较高工程应用价值。
Based on Pockels effect,lithium niobate(LN)electro-optical crystal is selected to design and fabricate optical voltage sensor with crosswise modulation method,in which the light goes along the z axis and the electric field goes along the xaxis.This sensor is small in size,passive sensor with high stability in temperature and time,high sensitivity,which is also immune to the electromagnetic interference.Characteristics of the sensor are tested both in experiment platforms in laboratory and outdoor,the results show that the sensor is of good value to be applied in practice,and is easy in extensive use.It is applied to the prwtical measuremeot of ourvoltage in xingreu ±50kV Comertor station which behings to China southru power Grid.
