摘要
介绍了GIS SF6保护的概况,分析了GIS SF6存在的设计缺陷、易误动等问题,阐述了改造的必要性;以母联开关2245甲为例,提出了利用PLC对GIS SF6改造的方案,并给出了GIS SF6保护进一步优化的建议。改造后使母联跳母线具有选择性,防止了事故的扩大。
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.
