籍供昆4382自锁怎么接线? -
鲁朗时18595783920 ______ 自锁 电动机起动后,松开启动按钮,接触器通过自身常开辅助触头而使线圈保持得电的作用称为自锁.实现自锁主要是将接触器触点并联于按钮,达到启动自锁功能:

籍供昆4382接触器的自锁,点动互锁,自锁加互锁,之类的接法,辅助点都用常开还是常闭,详细点 -
鲁朗时18595783920 ______ 自锁是A1,A2一个连接电源,一个接到常开点,常开点另一点上接常闭点和电源,然后常闭点另一点再过开关到电源,其过程就是开关控制一根电源线,开关闭合,接触器常开变常闭,由原常闭点供电到原常开点供电,接触器吸合后A1A2能一直连接电源

籍供昆4382请问这种六脚自锁开关的接线方式是如何 用来控制一个LED的亮... -
鲁朗时18595783920 ______ 六脚自锁开关的接线方式,一边有三角,一边连正级,另一边连负级,两条线分别连在两边中间,其他输出的就连同一旁的两条线. 原理图:

籍供昆4382金属圆形推拉自锁防水连接器5芯怎么接线 -
鲁朗时18595783920 ______ 图一 图二 楼主你好,首先金属圆形推拉自锁防水连接器5芯通常情况下有图一的这样三种情况,大部分是第一种,图一为插座的针芯排布,图二为左为插头的针芯排布,右为插座针芯排布,五芯也是一样,明白的了这个针芯排布,你应该就明白了,只要两两相对就可以了,即针芯是逆时针12345对应插座针芯的顺时针12345就可以了.要是还不明白的话加

籍供昆4382接触器如何接线.能自锁.一个起动开关.一个停止开关 -
鲁朗时18595783920 ______ 如果接触器线圈电压是380v一根火线连接起动开关常开点将接触器的辅助常开点并联,串联停止开关常闭点连接接触器的线圈A1将另外一根火线连接到A2上你不懂建议别弄设备烧了就麻烦找个电工帮你花点钱是小,出了事就麻烦

籍供昆4382一个五脚9v继电器和一个轻触开关如何接成自锁开关?
鲁朗时18595783920 ______ 五脚的继电器只有一组Z触点(单位两掷),也就是一个中间接头加上常开和常闭的另一端接头一个,最后两个接头是线圈接头.如果要能自锁,则需要利用其常开触点,这样这个继电器就只能作为常闭触点的开关了,且这个常闭触点还得与控制电路的9V是同一个电源组,不能独立.

籍供昆4382220伏接触器怎么接遥控的开关 -
鲁朗时18595783920 ______ 首先你要找到遥控接收器的电源并接上电,然后找到一组线,应该是一根公共线一根闭合一根断开!假如你需要的是点动的话就只需要闭合跟公共线,如果需要自锁就需要三根线!点动就把公共线和常开线接在接触器的线圈上就好了!需要自锁就,自锁就按自锁的方法接,公共线相当于电源线,常开线相当于启动按钮!然后回到线圈就好了!

籍供昆4382我有1个三相电机,1个交流接触器,1个2个按钮的开关,怎么接线 -
鲁朗时18595783920 ______ 1. 1个三相电机,1个交流接触器,1个2个按钮的双联开关,可以做一个三相异步电动机连续启动控制线路.2. 电原理图和实物接线图如下图所示.3. 工作原理:启动时,按下启动按钮SB2→接触器KM线圈得电吸合→kM辅助常开触头闭合自锁→KM主触头闭合接通电动机主回路→电动机得电运转.停止时,按下停止按钮SB1→接触器KM线圈失电释放→kM自锁触头释放→KM主触头断开电动机主回路→电动机停止.

籍供昆4382带灯带自锁的开关,上面有+ , - ,NC,NO,C.我用零线火线只接NO和C可以吗 -
鲁朗时18595783920 ______ 先看一个带灯带自锁的开关的图(右下角是接线图): + 、- ------ 灯的电源.因为有极性,所以这个灯应该是LED灯. NC ------ 常闭触点. NO ------ 常开触点. C ------ 公共静触点. 如果不需要指示灯亮,火线接C,零线通过负载接NO就可以了.注意,零线不能直接接到NO上!否则按下开关造成短路! 此时开关没有按下去时开关不闭合,按下去开关触点接通,电流则从C经NO、负载回到零线.

籍供昆4382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. -
鲁朗时18595783920 ______ 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...
