地下变电站大型变压器的吊装及运输方案的研究

Hoisting and transporting schemes for large transformers of underground substations

500 kV世博地下变电站为地下4层筒形结构,4层布置。变电站500 kV和220 kV变压器设备设置在-26.5 m的地下3层。变压器等设备从吊物井吊装方案以及在地下运输方式的选择是确保设备安全快速就位的关键。综合分析结果认为地下运输宜采用自行式液压平板车的运输方式。

The 500 kV underground Shibo Substation has a four-storeyed columnar structure, and its 500 kV and 220 kV transformers are planned to set on the third storey with the height of-26.5m, so it is important to establish suitable hoisting and transporting schemes for the transformers. The schemes of hoisting and transporting for the substation are recommended.
