1 总的部分适用范围本方案适用于远期2台主变建设规模的110kV GIS全户内变电站。

主要技术特点CSG-110B-G1a方案的主要技术特点如下: 序号项目名称技术特性主变压器本期2×63MV A，远期2x63MV A 1 建设规模110kV 本期2回，远期2回10kV 本期主变低压各装设3×6012kvar并联电容器组。

远期每组主变低压侧装设3×6012kvar并联电容器组
2 电气接线110kV 本期及远期采用内桥接线。

10kV 本期及远期采用单母线分段接线主变压器三相双绕组自冷有载调压电力变压器。

3 主要设备选型110kV 户内GIS设备单列布置。

10kV 户内移开式金属封闭高压真空开关柜。

主变压器主变户内布置 4. 配电
装置布置形式110kV 采用户内GIS设备单列布置，架空进、出线。

10kV 采用KYN开关柜户内双列布置。

二次设备布置形式集中布置直流系统按双充双蓄配置，单母线分段接线，电压采用110V5 电气二次或220V配置计算机监控系统按无人值班设计继电保护及安全自动装置采用微机型设备结构：采用现浇钢筋混凝土框架承重体系，现浇钢筋混凝土楼板、屋面6 土建板，砖墙维护，便于建筑房间的布置灵活，结构整体性好，抗震性能良好，较钢结构防火性能好。

使用边界条件方案不涉及系统接入论证，只是根据南方电网变电站普遍情况提出的典型建设规模。

方案不涉及短路电流计算，只是根据主流设备的制造与使用情况提出各电压等级的短路电流水平。

方案适用的站址自然条件海拔：1000m 以下；地震基本烈度：7度；设计基本风压：按不大于/m2考虑，50年一遇；覆冰：10mm以下；地
基承载力特征值：fak=150kPa；污区：d级地形条件：站址按已平整考虑凡站址自然条件较以上标准设计给定的条件恶劣时, 工程设计应依照有关规范作相应的调整。

方案适用的站址外部条件a) 人口密度高，土地昂贵地区。

b) 外部条件限制，站址选择困难区域。

c) 特殊环境条件地区，如污秽严重地区、高地震烈度或高海拔地区。

凡站址自然条件较以上标准设计给定的条件恶劣时, 实际工程设计应依照有关规范作相应的调整。

方案的模块拼接实际工程可通过使用本方案其他G1层模块组合而成。

具体G1层模块见应用手册。

实际工程可通过使用G2层模块进行规模调整。

具体G2层模块见应用手册。

模块拼接注意事项1）对于本方案不能直接适用的变电站，需要因地制宜进行分析后，选择合适的G1层模块，按照同类方案的设计原则进行，结合G2层模块的规模调整，形成所需要的设计方案。
