能汪趴4993求220V接触器双重互锁正反转实物接线图? -
童肥之15147201960 ______ 这个就是触点、按钮双连锁正反转接线图.双连锁实体图目前还没有.
能汪趴4993看不懂电路图怎么办 互锁单锁 不会 还有什么双重互锁 -
童肥之15147201960 ______ 1从点动开始说吧,点动就是一个接触器一个启动按钮组成的.按住启动按钮不放,接触器吸合.松开按钮,接触器断开.2自锁也就是你说的单锁,由一个接触器,一个启动按钮,一个停止按钮组成.按一下启动按钮,接触器吸合.再按一下停止按钮接触器断开.3互锁由两个接触器,两个启动按钮,一个停止按钮组成.互锁有几种接法,其中也包括双重互锁.按一个启动按钮,相应的接触器吸合,而另外一个接触器不会吸合.按停止按钮时,已吸合的接触器断开.
能汪趴4993电工技术电.路.图接.线求解答.
童肥之15147201960 ______ 四个按钮开关,两个线圈;SQ1常开点,串SQ2常闭点,一根电源L1串Y2辅助常闭点,最后进Y1线圈线圈出来接L2回路线,Y1的辅助常开点和刚才的SQ1常开点并联; 电源线LQ接SQ3常开点,串SQ4常闭点,串Y1常闭点,最后进Y2线圈,线圈出来接L2回路线.Y2线圈的辅助常开点和SQ3常开点并联.正反转就搞定了! 第一个打字的时候打错了,第二个对的,是按钮连锁,接触器互锁电路! 按钮连锁正反转,举个例子:其中一个(如正转)接触器启动按钮时,这个按钮的常闭触点先断开另一(如反转)接触器的回路后常开触点再接通这个接触器的回路
能汪趴4993电工互锁原理
童肥之15147201960 ______ 朋友 ,互锁其实就是电气连锁和机械连锁.电器连锁是利用控制电路的主副触头来互相牵制工作的,而机械连锁是利用杠杆原理来互相制动工作的.
能汪趴4993电工来看看这个接线图,上图,上接线电柜? -
童肥之15147201960 ______ 星三角启动是有3个接触器,主接触器KM启动后得电运行,KMΔ 还有KMY,就是主题 星三角启动 用的,所以必须3个接触器; 你接的主线路是对的,重点是KMΔ连接的电机绕组线,U1和W2 在一相电上,V1和U2,W1和V2,用KMΔ连接;
能汪趴4993复杂的电气原理图怎么看 -
童肥之15147201960 ______ 很明显简单的电气原理图你会看了,那么复杂的就变得简单多了.首先电气原理图图都是由若干的单独控制回路组成,比如CDW1断路器的二次控制原理,是由以下几个独立控制回路组成:控制器电源回路 欠压回路 合闸回路 跳闸回路 储能电机回路 分合闸指示回路 那么遇到复杂的图纸我们把它细化就可以了,拆分开来,单独弄懂它的原理,原后在整体来看
