氣封絕緣開關設備之接地及維護技術
Grounding and Maintenance Technologies for Gas Insulated Switchgears
摘要
以六氟化硫（SF6）氣體做為絕緣氣體的氣封F緣開關設備（GIS）已廣泛應用於電力公司變電所及用戶變電所，GIS的使用可使變電所空間大幅減少，並可設於屋內，使土地利用率大幅提高，同時也減少外在環境之影響，大幅提昇變電所的安全性及供電可靠性，並減少維護工作，不過在實務上GIS的安裝常出現不當的接地處理及維護問題影響GIS的運轉安全，前者包括GIS本體及電纜介面的接地問題，而後者牽涉到維護之項目及內容之相關困難點，為此，本報告將介紹相關接地及維護技術，主要是整理介紹相關文獻所研究之成果及GIS專業廠家的建議技術資料，其中亦可找出相關的改善對策供安裝及運轉維護之參考。

The gas insulated switchgear equipment (GIS) has been widely applied on the substations of utility and customers due to the advantages of reducing the substation space requirement significantly, and making the substation as indoor type thus increasing the benefit of land and preventing the environmental impact for less maintenance of equipments. All of these advantages of GIS will contribute to safety and reliability of substation . In practice, however, some problems of unsuitable grounding and maintenances are arisen from GIS installation which may affect the operation safety of GIS. The grounding problems cover GIS and its interfaces with the cables, while the maintenance problems concern the items, work contents and their reference basis and related difficulty. These problems are discussed in this report based on the study results from literatures and the technical information from manufactures of GIS. Where in ,in addition, improvement strategies can be found.
