【 摘 要 】

The complexity of the designing process of a switch disconnector framework comes from the almost impossible task to appreciate the discrepancy between the ideal and practical electric strength. Complicated geometries characterized by nonuniform fields are predesigned based on a set of analytical relations and corrected/optimized based on numerical methods and high voltage testing on prototypes. This paper suggest some approaches to minimize the effort and the steps required to achieve an acceptable stainless steel housing, in the insulators area, for a medium voltage SF6 switch disconnector. The results are based on simple analytical evaluation and finite element analysis in both 2D and 3D configurations.
