我省为了解决渭北高原农业灌溉用水,相继修建了一些高扬程大流量的大型电力抽水站,例如渭高抽、东方红抽渭以及关中东部抽黄土程,积累了不少的实践经验。现就我省南乌牛抽水站,谈谈大型电力抽水站电气一次设计的几点体会。南乌牛抽水站是我省关中东部抽黄灌溉工程4个二级站中最大的一个,装有四台“黄河四号”单级离心水泵,单机流量4.2米~3/秒,扬程107.95米,配四台 TD—215/120型8000KW 卧式同步电动机,电动机额定电压10.5KV,额定电流568A,励磁方式采用 KGL—12—600/110型可控硅励磁装
In order to solve the agricultural irrigation water in Weibei Plateau, the province has successively built some large-scale electric pumping stations with high lift and large flow rates, such as Weigao pumping, Dongfanghong and Weifang, and loessing in the middle of Guanzhong. Many practical experiences have been accumulated. Nanliu pumping station on our province now, to talk about a large-scale electric pumping station design of a few electrical experience. Nanwu Niu pumping station is the largest one of four secondary stations in Shaanxi Province, pumping yellow irrigation project, equipped with four “Yellow River No. 4” single-stage centrifugal pumps, single flow 4.2 m ~ 3 / s, lift 107.95 m , With four sets of TD-215/120 8000KW horizontal synchronous motor, the motor rated voltage 10.5KV, rated current 568A, excitation using KGL-12-600 / 110 type SCR excitation device
