摘　　要：真空电弧是一种强冲击电流,为了研究其伏安特性,需要选择合适的传感器,而罗氏线圈能很好地满足对真空电弧电流和电压采集的需要。以罗氏线圈传感理论作为研究主线,系统地分析了罗氏线圈的基本结构、材料选择、设计原则和步骤、电磁参数的选择与计算以及罗氏线圈等效电路等内容。最后结合真空短间隙电弧试验,对真空电弧进行电压和电流的采集,获得了较好的真空电弧伏安特性。The vacuum arc is a kind of strong impact current,in order to research its volt-ampere characteristic,the sensor should be chosen appropriately.The Rogowski coil satisfies the requirement for collecting current and voltage of the vacuum arc.With the theory of Rogowski coil as the researching thread,many things are analyzed systematically,e.g.basic structure of Rogowski coil,material selection,principle and steps of design,electromagnetic parameter selection and calculation as well as equivalent circuit of Rogowski coil,and combining with the experiment of short gap vacuum arc,the good voltage and current of vacuum arc are acquired thus the volt-ampere characteristic is obtained.
