摘要
介绍了一种将光学电流互感器和光学电压互感器同放于一个绝缘体内,可同时测量电流和电压的光电式一体化电流电压互感器。电流互感器采用法拉第镜式光学电流传感技术,电压互感器采用全反射光学电压传感技术,采用双光路补偿技术解决光强衰弱以及干扰双折射引起的误差。装置在佳木斯110kV佳西变电站糖厂线试运行,运行情况良好,满足现场实际要求。
A kind of photoelectric integration current and voltage transformer which can measure current and voltage simultaneously is introduced. Optical current transformer and optical voltage transformer are built in a same insulator. Faraday mirror-typed optical current transformers technology is adopted for current transformer and total reflection optical voltage sensor technology for voltage transformer. Double optical routes compensating technology is used for solving the error caused by light debilitating and birefringence. This device ran well during the trial operation in sugar factory power line of Jiamusi 110 kV substations and it can meet the practical requirements of the site.
