山西地区220kV户外变电站主变消防系统的比选

Comparison on main transformation firefighting system of 220 k V outdoor substation in Shanxi province

结合山西省内220 k V变电站实例,针对220 k V户外变电站浸油变压器的消防系统进行了研究,通过采用全寿命周期投资的方法对水喷雾型灭火系统、排油充氮型灭火系统及合成泡沫喷雾型灭火系统的技术性能进行了比较分析,提出了适应于山西地区的220 k V变电站主变压器消防系统(排油充氮灭火系统)。

Combining with 220 k V substation example in Shanxi province,the paper studies the oil immersion transformer firefighting system of220 k V outdoor substation,comparatively analyzes technical performance of water spray extinguishing system,oil discharging nitrogen charging extinguishing system and synthetic foam spraying extinguishing system by applying total life cycle investment method,and finally puts forward main transformation firefighting system of 220 k V substation fitting to Shanxi province（ oil discharging nitrogen charging extinguishing system）.
