探究中小型电排站电气设计及设备选型

Exploring the Electrical Design and Equipment Selection of Small and Medium-sized Electric Row Station

中小型电排站前期电气设计要充分考虑设备成本投入,文章结合笔者多年从事电排站电气设计的工作经验,从小型泵站电气设计和实际应用角度出发,详细分析了电排站设计中根据变压器容量和启动方式、水泵轴功率关系的选择原则,站用电选择原则,电动机选择原则,电动机启动方式选择原则,电动机启动器选择原则以及电容补偿原则等,希望对行业建设发展提供一定的参考价值。

The early stage electrical design of small and medium-sized electric power station should fully consider the equipment cost input. Combined with the author's years of experience in electrical design of electric power station, from the perspective of electrical design and practical application of small pump station, this paper analyzed the selection principle according to transformer capacity and starting mode, pump shaft power relationship, station power selection principle, motor selection principle, motor starting mode selection principle, motor starter selection principle and capacitance compensation principle. It is hoped to provide certain reference value for the development of the industry construction.
