220kV城区变电站小型化的探讨

Discussion on Miniaturization of 220 kV City Substation

城区供电变电站必须采用简洁明了、稳定可靠、占地面积小的布置。随着组合电气(GIS)越来越广泛的应用,新设备及功能强大的二次设备给变电站小型化打下了基础,城区变电站在借鉴已成功的江西省优秀工程220kV顺外变的基础上,对缩小城区变的占地面积方面,通过设备选择、方案优化的探讨,给城区变的设计提供一个可行的设计思路。

City power supply station must be arranged succinctly, stably and small occupied area. With the wider application of GIS,new equipment and the secondary equipment lay a foundation for substation miniaturization,Through the discussion of equipment selection and scheme optimization ,city substation provide a feasibility design thinking in aspect of reducing its occuppied area for city substation design.
