Recently, the project of substituting busbar mixed gas for Daheba, Hanzhong, Hanzhong, Shaanxi, undertaken by Western Electric, a subsidiary of Western China Electric Power Co., Ltd., was officially put into operation.The project is the first trial run station designated by SGCC in Shaanxi Province to use hybrid gas bus , Western Electric is responsible for the project planning and on-site implementation of the project.
The project uses SF6-N2 gas instead of SF6 gas as insulation medium for GIS bus equipment, which will significantly reduce the amount of SF6 gas used by GIS and is of great significance to the national energy saving and emission reduction and low-carbon development. , Without changing any parts and components under the conditions.Although Xikai electrical design department has carried out a full calculation, but the first case of on-site implementation.In order to ensure the smooth construction of the site, Xikai Electric Market Services developed a detailed program for the replacement of gas And the implementation of the key points Shaanxi Electric Power Company, Hanzhong Power Supply Bureau, Shaanxi Electric Power Research Institute and Western Electric Design, Market Services and other departments held a special topic on-site implementation of the program will be discussed and developed a contingency plan and reserve according to the contingency plan Related spare parts.
The project involves new fields of new technologies, the gas mixture ratio control, moisture control standards, gas chamber pressure settings, mixed gas density relay accuracy and temperature compensation are made more stringent settings.On the scene implementation, the Western Electric Departments are sent strong technical and experienced staff to participate in on-site work, we work together to overcome the difficulties encountered in the construction, and ultimately ensure that the project completed on schedule.The user on the open electrical workers in this dedication to work attitude and high quality and efficiency Service concept, deeply admiration and thanks.
The smooth operation of the project shows that XKC has the actual operation capability of GIS mixed gas bus and lays a solid foundation for XKC to gain the leading position in this field.
