Build-in Technique of Line-bar of Stator of Yixing Pumped-storage Power Plant

针对蓄能机组的特殊性,结合安装现场的实际情况,对发电电动机的绕组安装工艺进行探讨,采用半导体弹性硅胶全压模一次成形工艺制作线棒,根据线槽宽折线分布图嵌入线棒,嵌入过程简单易行,相对于其他工艺、大大提高了施工进度,减小了人工投入,简化了施工流程,并很好地解决了抽水蓄能机组频繁起、停机组带来的冲击等问题。

In line with the particularity of pumped-storage power generating unit and in combination with actual conditions of installation field, this paper discusses the installation technique of winding of power generator. The full-die single forming technique of semi-conductor elastic silica gel was used to manufacture the line-bar. The line-bar was builtin according to the wide broken-line graph of line groove. The build-in process is easy so that it greatly quickens the construction speed, reduces the manpower input and simplifies construction process and it solves the impact problems caused by frequent starting and stopping of generating unit of pumped-storage power plant.
