Abstract：With the high-speed development of our country’s economy and power loading, the user’s demand on the running reliability and quality of power grids are increasing. The retrofit of power grid has become a way to meet the demand. The gas insulated switchgear (GIS) equipment have unique advantages make the retrofits more safety and economical. The 500kV GIS reconstruction in Ningbo Beilun substation is one of the cases. Considering the effect and stability of the system substation reconstruction in original area, change the module which do not meet the system requirements and replace the parts with hidden dangers of GIS. That is to reduce loss of substation and improve the safety and reliability of equipment.

Key words： gas insulated switchgear (GIS) retrofit safety and reliability
