摘要
单相串激电机换向电势引起附加电流导致电磁性换向火花的产生,分析串激电机在换向时换向元件中存在的电抗电势、电枢旋转电势和变压器电势,介绍减少换向电势的方法。
Electromagnetic spark caused by additional current for reversing electrical potential of series motor is produced, reactance potential, armature potential and transformer potential of the reversing elements are analyzed, the method to reduce reversing electrical potential is introduced.
