Default 献给电气主动化专业的同窗(当前或者会用到)

10 延边三角形降压启动
2 直接启动,延时停止

(这个很主要,kayano asics,也和简略,也很适用的降压启动,个别电机大于7.5千瓦,为了维护电压网就应当采用降压的方 法。)

这个晓得就行!!!

5 电机轮流循环启动
7 单按钮控制电机启动停止
这也是很使用的降压启动控制线路。普通大于40千瓦的电机使用。
9 定子串电阻降压启动

应用双重互锁,采取复合按钮跟2个接触器。 将2个接触器的常闭辅助触点彼此串联在对方回路中,gucci 2011,保险便利,wholesale a&f,防止了短路的产生~


通过期间继电器作用,延时使回路断开。
