摘要
电力系统中光电电流测量技术是国内外研究的热点和难点 ,光电电流互感器是未来电力工业电流测量发展的趋势。文中基于传统的电流互感器 ,利用数字调制和光功率推动技术 ,对有源光电电流互感器进行了研究 ;基于法拉第效应 ,利用相位补偿和传感头组装技术 ,研制了块状玻璃式无源光电电流互感器。同时还讨论了几种光电电流互感器的发展状况。
In recent years,considerable effort has been devoted to the optical current measurement technology,which is an attractive but difficult subject. The optical current transformer OCT will be used to replace the conventional current transformer in the future.Based on the conventional current transformer,the paper presents an active OCT by utilizing A/D data modulation and optical powered technology.Based on Faraday effect,a bulk-glass passive OCT is developed by using phase compensation and sensing head assembly technique. The development of the optical current transformers is also discussed.
