ROFOR

基本解釋

It can be seen from the assembly averaged velocity profile that the location of the vortex in the tank changes with the relative location of rofor and stators.
通過集平均處理得到的某一轉(zhuǎn)速及動 /靜葉相對位置情況下的速度矢量分布 ;可顯示旋渦的位置隨動葉和靜葉的相對位置而變化 .
Checking and analysis revealed at last, that it was caused by residual magnetism after repair, the polarity of which was opposite to that effected by direct current in the rofor.
在水力發(fā)電公司檢修時,幾次碰到發(fā)電機不能啟勵建壓的情況,經(jīng)過檢查分析,最終確定為剩磁的原因,主要是檢修后剩磁的極性與轉(zhuǎn)子直流電產(chǎn)生的極性相反造成的。
