摘　　要：确保异步电动机的正常运行,使其在发生断相运行时及时停止电动机,避免造成电动机烧毁事故,除了需对电动机实行常规保护外,还有断相保护。本文对电动机的断相故障原因及断相保护方案等作了论述。In order to insure electromotor running safely and to be immune to burn-up while lost its phase.Besides of general safe considerations,some other protections should be taken into account such as lack-phase protection,so the rest of this paper will depict why electric-motor lost its phase and how to deal with the problem.
