三相电动机“断相保护”的研究

The Research on “Phase Failure Protection” of Three-phase Motor

电动机有负载运行、断相运行、空载运行及过载运行等好多种运行方式,在使用过程中,经常会出现断相运行的情况,在短时间内电动机就被烧毁,造成很大的损失。针对三相电动机的断相问题,提出了一些相应的保护措施。

Motor has a lot of running modes, such as load operation, open phase operation, no-load operation and overload operation. In the using process, the open phase operation condition is often appeared; the motor can be destroyed in a short time and cause a great loss. For this problem of three-phase motor open phase, the paper puts forward some corresponding measures to protect them.
