摘　　要：在分析了电容分压器测量电压和Rogowski线圈测量电流原理的基础上,研制出组合式电子互感器。重点介绍了电容分压器、Rogowski线圈的实用技术以及组合式电子互感器传感头的结构。对于电容分压器,采用等效电容作为分压电容器,详细介绍了分压电容器的结构,特别是采用固体绝缘材料代替传统的六氟化硫气体绝缘材料;对于Rogowski线圈,采用PCB罗柯夫斯基线圈来代替传统的绕制的线圈从而提高生产效率,提高产品的一致性。Based on analysis of measurement principle of current and voltage with Rogowski coil and capacitor voltage divider, the combined electronic transformer is developed . The capacitor divider and the Rogowski coils practical technologies, structure of the combined electronic transformer is focused on. For capacitor voltage divider, this project used equivalent capacitor as Voltage-divider capacitor, detailed on the structure of the Voltage-divider capacitor, especially in a solid insulating material to replace the traditional SF6 gas insulated materials. For Rogowski coil, the PCB Rogowski coil was used to replace the traditional Rogowski coil winding of the coil to enhance production efficiency, and improve product consistency.
