广申肤3836正反转三角形接法如何接 -
庾曼芝18440146054 ______ 正反转星三角启动器接线原理图讲解分析 正反转星三角启动器接线原理图 图例说明: KMa KMb——负责电动机正反转交流接触器 KM1——星形启动接触器 KM2——三角形启动接触器 KT——时间继电器 SB1-SB3——停止和启动按钮 FR...

广申肤3836接触器CJX02 - 0910的自锁和互锁接法? -
庾曼芝18440146054 ______ 接触器CJX02-0910只有一对常开触点,如果不另外加哪个辅助的触点是不能和别的接触器互锁的,这样的接触器在上面有另外加装辅助触点的地方.L12.T13 ,就是这一对常开触点.

广申肤3836接触器互锁怎么接 -
庾曼芝18440146054 ______ 你好:——★1、两台接触器互锁,就是当一台接触器吸合后,另一台接触器不可以吸合的装置.——★2、接触器都具有常闭触点,把自身的常闭触点串联到另一台接触器的线圈上,就可以达到自锁的目的.

广申肤3836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 -
庾曼芝18440146054 ______ 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

广申肤3836互锁触点如何连接 -
庾曼芝18440146054 ______ 互锁用在控制一个电机的正反转两个接触器之间.将正转接触器的一组常闭触点串接进控制反转的接触器线圈回路,同时将反转接触器的一组常闭触点串接进控制正转的接触器线圈回路.

广申肤3836电路图的自锁是怎么接线的? -
庾曼芝18440146054 ______ 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

广申肤3836请问为什么自锁要这样接,电工初学,求高手详解 -
庾曼芝18440146054 ______ 此停止按钮是常闭开关,启动按钮是常开按钮(关于常开常闭应该好理解啊,看它经常处于的状态),当按下启动按钮的一瞬间,电路闭合,有电流通过接触器下的电磁铁的线圈,将衔铁吸下,三相交流电接通,同时由于将主电路导通,当你松开启动按钮时接触器下的线圈仍然有电,使电路接通.同样当按下停止按钮时,电磁铁上的线圈失电在弹簧力的作用下主电路开关断开,实现对强电的控制.这是从接触器工作原理和开关触点形式角度说的,不知这样说是否能理解.建议先学低压电器的基本工作原理和作用比如继电器,接触器,延时器,各种功能开关的功用等.原理搞清楚,再接线实际操作时就易懂了.

广申肤3836实习电工求解接触器自锁联锁的工作原理?
庾曼芝18440146054 ______ 控制回路:火线----停上开关-----运行开关(并连在接触器常开辅助触点)-----接触器线圈------零线.这是按接触器线圈AC220V描述的

广申肤3836自锁互锁电路详细讲述? -
庾曼芝18440146054 ______ 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,

广申肤3836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.
庾曼芝18440146054 ______ <p></p> <p> </p> <p>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...
