摘　　要：高炉电动鼓风机是大高炉生产的一个至关重要的环节。需要以同步电动机安全为前提,并保证其连续运行。而当断电时,同步电动机通过备用电源自投,实现连续正常运行的是可行的。本文在详细论述此原理的基础上,介绍了一项具体应用实例的设计思路与实现方法。Fans of blast furnace is one of the most important devices in Iron＆Steel industry. On the premise of safety guarantee, it is important to keep the working continuity of synchronous motors. In case of poweroff , it is available to ensure synchronous motors＇s working continuity by means of using reserve power .source automatic connection device. In this paper , it introduce the design and implement of a practical system on the basis of analysis on this principle.
