| Abstract: | It is introduced the characteristics of GIS combination electric appliance and its application in all 110 kV systems in 5 main transformer substations of Cheng Steel. On May 23, 2014 a dielectric breakdown occurred in SF6 combination switch of No. 1 main transformer substation and made loss of power in the whole station and 40 000 m^3 oxygen concentrating system stopped and oxygen feed for blast furnace is limited. It is analyzed the power supply operation way of No. 1 main transformer substation, accident procedure, the emergency plan and control measures to get experience and lessons to avoid the same thing happen again. |
