Abstract:
     The main contents of the present invention is to use automatic magnetism-eliminating switch and non-linear resistance assembly which is connected paraletty to the magnetizing winding to eliminate megnetism jointly. By so doing a new connecting method for magnetizing circuit is formed, and the circuit can also be used as protection from overvoltage of rotator and for improving the magnetism-eliminating characteristics of the generators, the above said non-line resistance assembly contains two new technical solutions, which are the method for current sharing by using normal equivalent linear resistances connected in series in each branch with parallely connected multiple non-linear resistances, and the current turnoff method under forward working voltage using rectifying devices connected in series.
