摘要
针对智能变电站信息数字化、功能集成化、结构紧凑化的要求,开发了一种用于三相共箱气体绝缘开关的新型电子式电流电压组合互感器,介绍了其原理、结构、主要技术参数及应用情况,并对其实用化关键技术进行了分析。实际工程应用表明,该产品运行稳定可靠,应用前景广阔。
Aiming at the requirements of information digitalization, functions integration and compacted structure in intelligent sub- station, this paper developed a new type of electronic transformer combining current with voltage, which could be used for three-phase common case gas insulated switchgear （GIS）. Introduction was made to its principle, structure, main technical data and application, and analysis was carried out for its practical key technologies. Practical engineering application shows that the product is stable and reliable in operation with broad application prospect.
