简拜复4914自锁怎么接线? -
郎路疯13448276945 ______ 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:

简拜复4914什么叫自锁,互锁?如何实现?电工基础 电工论坛 -
郎路疯13448276945 ______ 依靠接触器自身辅助常开触点使其线圈保持通电的作用称为“自锁”.实现自锁的方法是将接触器自身辅助常开触点与启动按钮并联. 所谓“互锁”是指当一个接触器工作时,另一个接触器不能工作.在控制线路中可以利用两个接触器的常闭触点实现相互控制.

简拜复4914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 -
郎路疯13448276945 ______ 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

简拜复4914自锁互锁电路详细讲述? -
郎路疯13448276945 ______ 自锁就是动作后保持原状志如接触器触点和起动按钮并联.互锁就是A动作后B不能动作,B动作后A不能动作如正反转电路,

简拜复4914hager EPE524自锁继电器怎么接线
郎路疯13448276945 ______ 这样给你说吧,你有两个继电器,220V.你把第一个继电器的一端线圈线接到第二个继电器的常闭辅助触点上,然后接到火线上面.第一个线圈的另一端就接零线 / 然后 你把第二个继电器的线圈任意一端接到第一个继电器的常闭辅助触点上,然后出去接到火线上,第二继电器线圈另一端接零线,不就都可以互锁了,如果你把第一个继电器吸和,那就把第二个继电器的线圈常闭给断开了,第二个就怎么也不会吸合,反之,如果你把第二个继电器吸合了,那第一个继电器的线圈线在第第二个常闭辅助触点不就断开了..说白了,就一个继电器的线圈经过另一个继电器的常闭触点,另一个继电器的线圈经过这一个继电器的常闭触点,当任意一个继电器吸合就会断开另一个继电器的线圈线,就这样,简单的很.

简拜复4914请问三相异步电动机接触器做互锁的自锁环节是怎样连接的 -
郎路疯13448276945 ______ 自锁是1个接触器接法.互锁是2个接触器接法.控制正反转用的

简拜复4914电路图的自锁是怎么接线的? -
郎路疯13448276945 ______ 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

简拜复4914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!
郎路疯13448276945 ______ 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.

简拜复4914如和实现继电器的自锁和互锁? -
郎路疯13448276945 ______ 实现自锁和互锁都要用继电器的辅助触点来完成的,首先你要明白什么叫做自锁,什么叫做互锁,自锁就是用自己的触头将本接触器线圈回路的按钮开关给短接掉,在按钮开关松开以后使得线圈回路不断开,这就是自锁.这样你就可以利用继电...

简拜复4914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. -
郎路疯13448276945 ______ 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...
