摘要
H级绝缘的防爆电机由于加强了绝缘处理,电气强度可靠,与普通电机相比使用更安全。文章针对H级不同电压等级的三相异步防爆电动机的绝缘结构及其可靠性进行了探讨。
Ex motor with H - grade insulation structure has higher reliability, comparing to that of standard motor, for higher quality of insulation. It probes into the different insulation structures for various voltages applied on Ex three - phase induction motors and its reliability.
