摘要
以某工程项目为例,对超大型建筑群35/0.4kV和35/10/0.4kV两种变配电方案的主要设备投资、占地面积、电能损耗等几方面进行了技术经济比较,该项目最终采用了35/10/0.4kV二级变电方案。
Taking a project as an example, a technical and economic comparison between 35 / 0.4 kV and 35 / 10 / 0. 4 kV power transformation and distribution schemes for ultra-large buildings substations are made on several aspects, such as the major equipment investment, floor area, power consumption and so on, the project has finally adopted a 35 / 10 / 0. 4 kV two - stage power transformation scheme.
