明陈杨2131这是一个互锁电路图,那个KM1与KM2是个什么接触器, -
萧姜欣18948703247 ______ 这个电路中,KM1是顺转接触器,KM2是逆转接触器.这个电路有个缺点,电动机通电以后,必须按停止按钮才能停止!更改按钮连线,可以实现正转时,按“停止”或者轻按“逆启”都停止(“逆启”按进到底,将会启动倒转!);倒转时,按“停止”或者轻按“顺启”停止(“顺启”按到底,将会启动正转!).更改以后,适应允许快速正倒转的应用场合. 希望对你有帮助.

明陈杨2131请教互锁电路! -
萧姜欣18948703247 ______ 点动正反转接触器互锁控制 接触器KM1的常闭辅助触点(9,11)串联在接触器KM2的线圈回路,当接触器KM1工作吸合时,接点(9,11)断开,即使误操作按下按钮SB2,由于KM2的控制回路在(9,11)处是断开的,KM2的线圈也不能得电,...

明陈杨2131请电工高手帮忙看看本人画的接触器互锁电路图正确不正确. -
萧姜欣18948703247 ______ 不对,电机顺、逆转控制的电机线不是这样的,同时,顺、逆互锁的接触器常闭触点也不能这样接,否则,一旦其中一个接触器粘连,按另一个启动钮也能将接触器通电动作引起电源短路的.参考附图正确线路:

明陈杨2131结合接触器联锁正反转控制线路图说明其工作原理
萧姜欣18948703247 ______ 大致说下接触器联锁电路,按下正键,正接触器吸合,其常开闭合自锁,同时其常闭断开,切断了反接触器线圈电路,此时按下反键,反接触器也无法吸合,只有断开正接触器,使其常闭闭合后,按下反键才能反吸合,反吸合后同理正接无法吸合,还有一种按键联锁 按键联锁或接触器和按键双重联锁,当正转吸合后,直接按下反起动键,反键常闭先断开,正接触器释放,然后才是反起动键常开闭合,反接触器吸合,此种电路省去了每次换向必先按停止键的工序,操作更加简便,我一般才用此法安装,另我相册中有很多此种电路图,

明陈杨21312个接触器,1个热继电器,2台电动机,4个按钮.怎么形成互锁,求电路图 -
萧姜欣18948703247 ______ 楼上的线路图堪称完美!但是如果两个电机在实际工作中要求很严格,绝对不允许同时工作的话,在电路中还缺少了按钮互锁部分!改动的话很简单:在FU控制线路保险丝的后级串联一个总的停止开关,一般开关里面都有常开和常闭,没有你说的那个启动和停止的定律...这个只不过是开关在线路工作中起到的一个作用!这样说就是左上脚的停止和KM2常开触点上面的按钮是一整体,左下脚的停止和右上脚的KM1上面的按钮是一整体!可以想象,当按动左上角停止同时也闭合了右下脚的按钮,这样停止了KM1,启动了KM2!同理另外一组也是如此!如果不要另外一个电机转动时可以按总停止按钮...这在正反转电路中比较常见...也不知道能否适合你的实际工作需要...

明陈杨2131接触器联锁正反转控制线路特点 -
萧姜欣18948703247 ______ 正转控制:按下正转按钮SB1→接触器KM1线圈得电→KM1主触头闭合→电动机正转,同时KM1的自锁触头闭合,KM1的互锁触头断开. 反转控制:先按下停止按钮SB3→接触器KM1线圈失电→KM1的互锁触头闭合.然后按下反转按钮SB2→接触器KM2线圈得电→从而KM2主触头闭合,电动机开始反转,同时KM2的自锁触头闭合,KM2的互锁触头断开.

明陈杨2131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. -
萧姜欣18948703247 ______ 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...
