摘要
在对变电站配电装置的设计中,节约工程用地、降低工程造价是应该考虑的重要问题之一。分析了220kV室外配电装置的几种设计方案,比较了它们在占地面积、施工运行和检修维护的方便程度以及经济性等方面的差异,指出当前220kV室外配电装置布置有一种回归中型布置的趋势,并且有了改进和创新。在某220kV变电站设计中提出采用管型母线布置型式的改进中型布置方案,适当提高一组母线高度以节约用地,是对当前220kV室外配电装置的一种设计优化。
Saving land occupation and reducing project cost are important in the design of substation switchgear. Several design schemes of 220 kV outdoor switchgear are analyzed,and their differences in land occupation,construction,maintenance and economy are compared. It is pointed out that the medium type layout becomes again the current trend of 220 kV outdoor switchgear and some improvements and innovations are presented. An optimum design of medium,type scheme using tube bus is adopted in the design of a 220 kV substation,in which a bus group is properly raised to reduce land occupation.
