    目前，变电站GIS室通风设计过程中往往仅考虑SF6-O2浓度的报警与排风及消防报警。目前存在的问题是：没有针对GIS室的温度高、消防救援手动排烟及就地手动排风等进行设计。而且由于普通百叶窗依靠重力关闭的缘由，常常被高处流动的风吹开，导致风机周围落尘较多，需经常打扫，增加了巡检人员的工作量。 At present, only the SF 6 -O 2 concentration alarm, exhaust and fire alarm are often considered in the ventilation design process of the substation GIS room.
