摘　　要：抽水蓄能电站工程高压电缆出线方式的选择是工程设计的一项重要工作,一般情况高压电缆出线方式是根据地下主变压器洞和地面开关站的相对位置关系,可采用平洞、竖井、斜井或其组合的方式布置,经过布置设计、方案比选、论证分析最后确定。黑龙江荒沟抽水蓄能电站电缆出线方式的选择,是经过技术、经济、工期运行、维护等多方面论证研究,综合分析确定的布置型式,即电缆出线竖井与地下厂房排风竖井结合布置的型式。竖井具有电缆出线及地下厂房排风功能,同时兼有交通功能,属于"一洞多用"的布置型式。充分利用竖井截面,井内分隔成多个功能空间。The take-off mode selection of high voltage cables is an important work in the engineering design of pumped storage power station.Generally,the take-off mode of high voltage cable can be arranged into adit,vertical shaft,inclined shaft or their combination type according to the relative position relationship between underground main transformer cavern and ground switch station,and finally determined after scheme design,comparison,demonstration and analysis.The cable take-off mode of Heilongjiang Huanggou pumped storage power station has been demonstrated and studied in many aspects,such as technology,economy,construction period,operation and maintenance,etc.After comprehensive analysis,it is determined that the layout mode is the combination of cable take-off shaft and underground powerhouse exhaust shaft.The shaft has the function of cable take-0ff,ventilation of underground powerhouse,and transportation.It is a multi-purpose layout type of one shaft.This combined arrangement can make full use of the vertical shaft section to separate the shaft into multiple functional Spaces.
