摘要
抽水蓄能电站建筑物布局受山体走势影响较大,目前普遍采用斜井或超深竖井两种方式将地下厂房与开关站连通,通常采用500kV高压电缆将地下厂房GIS设备和地面开关站GIS设备相连接。黑龙江荒沟抽水蓄能电站因电缆自重过大,为避免在敷设过程中失控,高压电缆竖井设置耳洞,用以缓冲自重,通过前期论证与研究解决电缆因自重下落的问题,计算各部位牵引力为后期施工选择敷设工具、确定方案提供依据,也为其他蓄能电站竖井出线的高压电缆敷设提供参考。
The building layout of pumped storage power station is greatly affected by the trend of mountains. Inclined shaft or ultra-deep shaft is commonly used for connecting the underground powerhouse and the switch station currently. 500 kV high-voltage cables are usually used for connecting GIS equipment of underground powerhouse and GIS equipment of ground switch station. High voltage cable shafts are provided with side caves for buffering dead weight due to too heavy cable weight in order to avoid out-of-control failure during laying. The problem of cables because of gravity is solved through previous feasibility study and research. The traction of each part is calculated,thereby providing basis for selecting laying tools and determining schemes in subsequent construction,and providing reference for high voltage cable laying of shaft outgoing lines in other pumped storage power stations.
