Abstract: Aiming at the requirements of information digitalization, functions integration and compacted structure in intelligent substation, 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.
Key words: gas insulated switchgear; three-phase common case; electronic transformer; very fast transient overvoltage
