摘　　要：某中型灌区为四级提水泵站灌溉工程,经过多年的运行,灌区电气设备长期得不到及时到位的维修和更新,部分已成淘汰产品,电气设备老化严重,事故频繁发生,安全运行没有保证,严重影响了泵站效益的发挥。针对灌区电气系统存在的问题,对灌区电气系统进行更新改造设计,并重点对35/10kV户内变电站设计方案进行研究,包括变电站站址、型式,主变压器选择、电气接线、用电系统、照明、自动化以及变电站二次回路设计等,为该工程及同类型工程提供技术参考。A medium-sized irrigation area is a fourth level pumping station irrigation project.After years of operation,the electrical equipment in the irrigation area has not been timely and updated,and some have become obsolete products.The electrical equipment is severely aging,accidents occur frequently,and safe operation is not guaranteed,which seriously affects the efficiency of the pumping station.To address the issues with the electrical system in the irrigation area,update and redesign the electrical system.This paper focuses on the design scheme of 35/10kV indoor substation,including substation site,type,selection of main transformer,electrical wiring,power system,lighting,automation,and secondary circuit design of the substation,providing technical reference for this project and similar projects.
