光电混合式电流互感器的研究

Research on the Opt-electronic Hybrid Current Transformers

基于罗科夫斯基线圈的电子式电流互感器的原理,提出一种采用激光器(POF)供电的混合式光电电流互感器,采用激光器(POF)结合一次高压侧组合供电,提高了互感器稳定性,是一种很有发展前景的新型互感器.

The theory of electronics current transformer is briefly introduced based on Rogowski coil and the analysis of its error. Then the Opt-electronic hybrid current transformer is designed by using laser to supply the current power. Optical signal transmission is applied in the transmission line to improve the stability of the transformer.
