我县某水电站一台100瓩4级的水轮发电机,因外力损伤了发电机定子线圈的端部,经检查分析后,因只断了同一极相组线圈端部的六根线,决定在现场进行修理工怍。该电机定子48槽,一相极相组联接图见图1。由图可见,每个极相组就是一个并联支路。拆开端部联线检查,每个极相组又由三根粗约φ1.56 A hydropower station of a hydropower station in I County, a 100 瓩 4 hydroelectric generator, damaged the end of the stator coil of the generator due to external force. After checking and analyzing, only six lines of the coil end of the same pole phase group were broken, On-site repairman 怍. The motor stator 48 slots, a phase pole phase connection diagram shown in Figure 1. As can be seen from the figure, each pole phase group is a parallel branch. Open the end of the line check, each pole phase group by the three rough about φ1.56
