直流电磁铁在轴流风机逆流保护系统中的应用

Application of the direct current electro-magnet in automatic control system of countercurrent protection of non-return valve of axial flow air compressor of blast furnace

文章介绍了直流电磁铁一种新的应用——作为自控系统的执行机构的驱动装置,分析比较了几种驱动方式的优、缺点,说明了直流电磁铁新的应用前景。

The new application of direct current electro-magnet is introduced in this article.i.e：The driving equipment of performing framework is made up direct current electro-magnet in the automatic control system.The paper analyses and compares the advantage and disadvantage of several driving mode.Meanwhile, makes out the latest applied foreground of the direct current electro-magnet.
