郝曲谢2821电气原理图所对应的接线图怎么画 -
姬万呢18527039060 ______ 1首先得看懂电气原理图. 2识别电气原理图所有控制元件,被控元件的接线端子,将原理图中接线端子与实物原件接线端子对应. 3手画实物接线初稿,修改完成确认. 4将手搞完成CAD电气制图. 熟悉的话不需要手稿环节.

郝曲谢2821求电工师傅帮忙,画出以下设备简单接线图,实现所需功能. -
姬万呢18527039060 ______ 根据现有原件和要求画了个图,不知发的第一张照片是不是地磁感应器,如果触点容量是6A的话带动交流接触器够了.不过电路中缺少电源开关,我就加了一个空气开关,其实有了空气开关熔断器就多余了.按理说控制电路也应该装一个2A的熔断器.工作原理:合上电源换开关,感应器GY得电,有车通过时GY动作,常开触点闭合,交流接触器KM吸合并自锁,即使汽车通过并离开感应器也不掉电,水泵电机开始工作,同时时间继电器SJ得电开始计时.当设定时间到,SJ常闭触点断开,交流接触器断电,水泵停止工作,同时个触点复位.当下一辆车经过感应器时重复上述动作.图中带圆圈的数字是时间继电器的引脚号.

郝曲谢2821西门子单控开关怎么接线 -
姬万呢18527039060 ______ 您好,1、这是单联开关,上下对应是一组,共四组开关,也就是上下接线,就能控制用电设备了! (1天前 ) 2、L上接火线N上接零线,方便你以后排查电路好维修,若不懂得话尽量别接,安全重要,建议你请个专业电工接线. (3天前 ) 3、这...

郝曲谢2821电工来看看这个接线图,上图,上接线电柜? -
姬万呢18527039060 ______ 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;

郝曲谢2821电机正反转实物接线图 -
姬万呢18527039060 ______ 我们知道三相交流电机如果想换个转向,则只要把其中两相对换就可以,那么你说的接触器正反转也是这个原理.仔细观察你会发现,KM1吸合与KM2吸合对比,正好是其中A相与C相对换,从而实现正反转之间的转换.没有实物,只能看图. QS:...

郝曲谢2821电流互感器接线图 -
姬万呢18527039060 ______ 电流互感器P1 P2 要与S1 S2一致,如果互感器反穿了,相应的二次线也要反接,不然会出现电表反转

郝曲谢2821电工知识,这个接线图是不是错了,朋友说这样接电表不转 -
姬万呢18527039060 ______ 电表会转的.电度表正确接法:左起第1个孔=火线入.第2个孔=火线出.第3个孔=零线入.第4孔=零线出.现在的图片左上角是个互感器吧,现在互感器孔的穿线方向应该是错了,但是不影响电表转动,只不过线穿反了,电表会反转.如果反转,应该把穿孔线换方向.

郝曲谢2821哪位大神电工说说怎么接线啊,最好有个详细的接线图或者详细说下接线
姬万呢18527039060 ______ 公牛墙壁三联开关接线图,红线接火线、

郝曲谢2821电气接线图什么意思 -
姬万呢18527039060 ______ 电气原理图是根据控制线图工作原理绘制,具有结构简单,层次分明.主要用于研究和分析电路工作原理,要想看电气原理图要先清楚其中的电气原理及其符号所表示的含义.看原理图先看主电路,再看控制电路.对于控制电路要熟悉典型控制...

郝曲谢2821如何连接电路实图和画电路图? -
姬万呢18527039060 ______ 其实挺简单的 分清正负极 电源 开关 和各个元件间的关系 画电路图首先克服怕难思想,然后要掌握方法. 画电路图题型大约可分为以下几种: 1、看实物画出电路图.2、看图连元件作图.3、根据要求设计电路.4、识别错误电路,并画出正确...
