变电站户外电气设备防火距离研究

Research on the Fireproof Distance of the Outdoor Electrical Equipment in Substation

变电站户外电气设备的防火距离影响着设备总体布置,在设备布置的安全性和经济性之间寻求平衡,是十分必要的。鉴于目前相关标准不统一的现状,结合对防火原理的深层次分析,对户外电气设备的防火要求进行分类研究,归纳出指导工程设计的优化措施,以更好地适应变电站"两型一化"的建设要求。

The layout of the outdoor electrical equipment in substation is affected by the fireproof distance. It is extremely necessary for equipment layout to find a balance between the security and economy. But the relevant standard is not unified currently. To improve the situation, the fireproof requirement for outdoor equipment is studied by classification. Besides, to adapt to the requirement better for constructing the ＂Resource-saving, environment-friendly and industrialized substation＂, the optimization measures which can guide engineering design is also summarized.
