1、 1 摘 要 魏村西抽水站是太湖治理工程中灌排结合的大型泵站。泵站设计流量 75m 3/s,设计扬程为 2.5m。由流量和扬程的大小,选择 5 台 2000ZLQ15-2.8 型轴流泵。单泵流量为 15m 3/s。同时配有 5 台 TL215/21-24 型同步电动机。 进水流道设计为平面蜗壳式双向进水流道,出水流道设计平面蜗壳式双向进 水流道,类似倒置平面蜗壳式双向进水流道。泵站采用的泵房形式为块基型 泵房。泵站设计中对主机应用了先进的微机保护。主变压器则用了传统的继 电保护,结合泵站的实际情况,主变压器选用的是 SL9-3150/35。泵站的电力 供应是由位于站址西南的变电所架设 10kM
2、 专线供电,选用 35KV 的电压等级。 高压开关柜设置在管理处主控室,低压开关柜设置在副站房。 关键词:泵站,结构设计,电气设计 2 ABSTRACT Weicun West pumping station is a large irrigation/drainage pumaing station in harnessing TaiHu lake control key project. The flux of the pumping station is 75m 3/s and the head of the station is 2.5 m. For the characteristi
3、cs of the discharge and head,I select 5 vertical propeller pumps ,the type of the pump is 2000ZLQ15-2.8 ,and the flux of each pump is 15m 3/s .And chose the electric motors with the type of tdl215/21-24.The form of incident flow pipe is reversible passage ,which is similar to the shell of the house
4、of a snail ,the form of outlet pipe is reversible passage too, be similar to the reversed form of incident flow pipe. The pumping house of the pump station is a block-together structure pump house. We use the computer to control and protect the electric motor. The main transformer has used tradition
5、al relay protection. Combining with the actual conditions of the pumping station, the type of the major transformer is selected to SL9-3150/35. The electric power of pumping station is provided by the substation, which lies in the southwest of the pump house, and erect a 10kM length special line for power supply, select the voltage grade of 35KV for use. The high-pressure switch cupboard is in the top management room of managemen
