摘要
通过人为改变换向电势大小 ,打破电抗电势与换向电势平衡。用试验的方法考核电刷承受这种破坏的能力 ,承受能力越大 ,换向性能越佳 。
The size of reversing electric potential may be changed and equilibrium between reactance electrical potential and reversing electrical potential may be broken by manual.This destructive supportability of brush is tested using examination way,The greater the supportability is,the better reversing property is ,the lesser spark is.
