摘要
环火是直流电机换向恶化的极限状态,其原因及发展过程极为复杂。本文结合轧钢电机环火典型实例,分析环火的主要成因及发展过程,并对防止环火措施进行了讨论。
Looping are is the worst opration state of the commutation in D. C. machine. The cause and growing process producing looping arc are very complicated. In this paper the main cause and growing process of them are analyzed in combination with exampl of producing looping arc in D.C. machines in steel mill, meanwhile the measure for preventing looping arc in also discussed.
