摘要
以杭州市轨道交通2号线二期工程终点站良渚站区间废水泵配电设计为例,对长距离供配电线路的开关选型、保护整定、电缆截面选择进行探讨。现场调试及运营效果表明该设计合理,可为类似项目优化设计、避免浪费、消除安全隐患等提供借鉴。
Taking the power distribution design of the waste water pump in the section of the terminal Liangzhu station in phase II project of Hangzhou Metro Line 2 as an example,the switch selection,protection setting and cable section selection of the long-distance power supply and distribution lines are discussed in this paper.The field debugging and actual operation results show that the design is scientific and reasonable and provides a reference for designers to optimize design,avoid waste and eliminate hidden dangers in similar projects.
