祁帝昌3722正反转双重联锁控制电路按钮怎么接 -
钟劳战15552759111 ______ 1、双重联锁的正反转控制线路原理图: 由于电机正反转的实现是通过改变电源相序来实现的.因此,我们采用两个交流接触器来进行换相,以达到控制电机的正转和反转的目的.用两个按钮分别实现正转和反转的控制,并把它们的常闭触点分...

钟劳战15552759111 ______ 在电路中采用可靠的双重互锁,下边为采用按钮和接触器双重互锁的电动机正、反两方向运行的控制电路. 分析: 一、正向启动: 1、合上空气开关QF接通三相电源636f7079e79fa5e9819331333330326134 2、按下正向启动按钮SB2,KM1通电...

祁帝昌3722求这张三相异步电动机自锁正转控制线路电气原理图的实物图,不知道怎么接实物,实训用的,谢谢大家!
钟劳战15552759111 ______ 这个很简单啊,首先搞清楚KM是接触器、FR是热继电器、SB是按钮就行,然后在主电路(一次电路也是上图的左边部份)的KM、FR接在实物的主接线端子上,而右边的部份也就是二次回路,则要接在辅助端子上,其它按钮就按图纸接上线就行了.希望能给你帮助.

祁帝昌3722电路图的自锁是怎么接线的? -
钟劳战15552759111 ______ 按钮开关与接触器常开触点(13NO、14NO)并联,按动按钮接通电源,接触器通电吸合,常开触点接通替代按钮通电成为自锁. http://hi.baidu.com/%B3%C2%BC%E1%B5%C0/album/item/eebf313c86970fc63d6d9714.html

祁帝昌3722谁能画电机正反转自锁控制电路
钟劳战15552759111 ______ 每个图都有自锁功能,也能达到正反转达到你所说的电机正反转自锁控制电路;这几个图所不同的就在于它的互锁能功不一样而已:前图只有接触器单重互锁;而后图具有按钮和接触器双重互锁.

祁帝昌3722电工高手帮我,画一个自锁 互锁 连锁电路?面试电工用的啊!帮帮忙. -
钟劳战15552759111 ______ 第一个图是按动按钮开关sb2接触器km1线圈得电,这个时候接触器常开点吸合,km1常开点闭合,这时松开sb2按钮,km1线圈不会失电,会继续吸合,这就实现了自锁,要线圈断开即停止工作,就按动常闭按钮sb1就断开了线圈的电,这时接...

祁帝昌3722两个接触器的辅助触点常开常闭怎么接正转反转联锁,求详细!求图纸!谢谢. -
钟劳战15552759111 ______ 这个图纸是互锁的,正转和反转接触器线圈互相串另一个接触器的常闭触点,功能就是,正反转两个接触器都是,只有另外一个接触器分闸状态才回吸合工作

祁帝昌3722求下图正反转互锁实物接线图!!! -
钟劳战15552759111 ______ 这图和你的原理图相比,少了热继电器,用空气开关代替了熔断器. 下图才是真正的正反转实物控制图.
