摘要
500 kV静安(世博)地下变电站按全地下设计,本体形状按圆形结构考虑,地下结构层按4层考虑,地面层仅留主控室、进出口和进出风口。顶面标高为-2.00 m,其余每层面标高分别为-11.50 m,-16.50 m,-26.50 m和-31.00 m,具体分块按圆形四等分考虑,其中3个单元基本为500 kV降压部分,另外1个单元为220kV降压部分。考虑成本和国产设备生产能力,变电站内选择油浸式变压器和电抗器类设备。500kV主变压器的第三绕组电压推荐采用66kV电压。
The 500 kV Jing＇ an （World Exposition） substation is designed to be a fully underground substation. Its main body is a rounded structure. The underground structure consists of 4 floors while only the main control room, entrance/exit, and intake/outtake remain above ground. The elevations of top surface and remaining 4 floors are -2.00 m, -11.50 m, - 16.50 m, -26.50 m, and -31.00 m, respectively. The main structure is divided equally into 4 blocks, 3 for 500 kV step-down and 1 for 220 kV step-down. Taking into consideration of cost and domestic manufacturing capability, oil-immersed transformers and reactors are used. The recommended voltage for the No.3 winding set of the 500 kV main transformer is 66 kV.
