Abstract
The paper introduced general situation of GIS SF6 pressure protection,analyzed problems of design defect and faulty start existed in GIS SF6,discussed reform necessity. Taking bus-tie switch 2245 as example,it put forward a reform scheme used PLC for GIS SF6 and gave some further suggestions of optimal protection of GIS SF6. The reformed bus couple jumping with bus has selectivity,prevents accident to be expanded.关键词
