电工电路中断路器和交流接触器接线图

断路器主要用作供电线路的保护开关、电动机及照明系统的控制开关，也可用于输、配电系统的某些重要环节。当线路发生短路、过载、欠压等故障时切断故障电路.
　　接触器在机床中用于频繁的接通和分断大电流的电路，具有动作迅速、操作方便和便于远距离控制的特点，但本身不具备短路保护和过载保护能力，因此必须与熔断器、热继电器配合使用.

　　接触器的接线方法有很多种，用的地方不一样，接线方法也不一样，这里指的是接触器的单一接法和多个接触器的接法，一般最常见的就是利用断路器、

按钮开关、热继电器、延时继电器、数字继电器等低压控制元器件产品组合。其实，无论你用什么接触器其功能和工作原理都是一样，无非是外形不一样。

　　主触头：三个主触头（用来接主控制电路）。

　　辅助触头：现在常用的接触器有CJX1、CJX2接触器这两个产品在辅助触头上有区别，CJX1是由四组辅助触点，可分为2NO(常开）、2NC(常闭），而CJX2从9A-32A都是有一组辅助触头，可组装成 10表示常开；01表示常闭。

　　控制电源：这里就是我们说的线圈电压，正常使用的一般为220V,380V,特殊伏数有12V，24V，36V，48V，72V，110V等。

　　顺序启动、停止控制电路是在一个设备启动之后另一个设备才能启动运行的一种控制方法，常用于主、辅设备之间的控制，如上图当辅助设备的接触器KM1启动之后，主要设备的接触器KM2才能启动，主设备KM2不停止，辅助设备KM1也不能停止。但辅助设备在运行中应某原因停止运行（如FR1动作），主要设备也随之停止运行。

工作过程：

　　1、合上开关QF使线路的电源引入。

　　2、按辅助设备控制按钮SB2，接触器KM1线圈得电吸合，主触点闭合辅助设备运行，并且KM1辅助常开触点闭合实现自保。

　　3、按主设备控制按钮SB4，接触器KM2线圈得电吸合，主触点闭合主电机开始运行，并且KM2的辅助常开触点闭合实现自保。

　　4、KM2的另一个辅助常开触点将SB1短接，使SB1失去控制作用，无法先停止辅助设备KM1。

　　5、停止时只有先按SB3按钮，使KM2线圈失电辅助触点复位（触点断开），SB1按钮才起作用。

　　6、主电机的过流保护由FR2热继电器来完成。

　　7、辅助设备的过流保护由FR1热继电器来完成，但FR1动作后控制电路全断电，主、辅设备全停止运行。

常见故障；

　　1、KM1不能实现自锁：

　　分析处理：

　　1)、KM1的辅助接点接错，接成常闭接点，KM1吸合常闭断开，所以没有自锁。

　　2)、KM1常开和KM2常闭位置接错，KM1吸合式KM2还未吸合，KM2的辅助常开时断开的，所以KM1不能自锁。

　　2、不能顺序启动KM2可以先启动；

　　分析处理：

　　KM2先启动说明KM2的控制电路有电，检查FR2有电，这可能是FR2接点上口的7号线，错接到了FR1上口的3号线位置上了，这就使得KM2不受KM1控制而可以直接启动。

　　3、不能顺序停止KM1能先停止；

　　分析处理：

　　KM1能停止这说明SB1起作用，并接的KM2常开接点没起作用。分析原因有两种。

　　1)、并接在SB1两端的KM2辅助常开接点未接。

　　2)、并接在SB1两端的KM2辅助接点接成了常闭接点。

　　4、SB1不能停止；

　　分析处理：

　　检查线路发现KM1接触器用了两个辅助常开接点，KM2只用了一个辅助常开接点，SB1两端并接的不是KM2的常开而是KM1的常开，由于KM1自锁后常开闭合所以SB1不起作用。

另介绍一种改进交流接触器接线方法:

　　交流接触器等电气设备的接线端子有很多是采用拱形垫片的。这种接线方法对一个接线端子接一个线头是不成问题的，但要同时接几个线头或粗细不等的线头时，就会产生接触不紧密、螺钉易松动的现象。尤其当接触器用于频繁吸合和释放时，接线端子上的螺钉更易松动。这样就使拱形垫片与线头之间的接触电阻增大，甚至脱离，造成电气设备不动作或发生单相运转等故障。针对上述情况，交流接触器接线端子是拱形垫片时的正确接线方法应是：

　　先在拱形垫片下加两个平垫圈，接线时先把细线或软线弯成一大半圆圈，套在两个平垫圈之间，然后把粗线压在拱形垫片下，把螺钉拧紧，这样无论怎样振动，都和接线端子只接一个线头一样牢固和安全。

能君隶3049220的交流接触器接380的电机接线图 -
索毛芬13414002735 ______ 如果你的电动机是380V电压的,那么电动机名牌上的接法中必须有星形接法(即Y形接法)才行.如果仅有三角形接法(即△),那么就不能接入220V. 如果有380V动力电则直接接入电动机主回路,仅是接触器线圈控制回路接220V即可.

能君隶3049380V交流接触器怎么接无线遥控开关 -
索毛芬13414002735 ______ 1、遥控器的输出一般是36V或220V,遥控器的输出控制中间继电器,再由中间继电器可在接触器. 2、遥控器的输出一般是36V或220V,遥控器的输出控制中间继电器,再由中间继电器可在接触器. 3、无线遥控开关是采用射频识别(Radio frequency identification )技术,用无线遥控器控制各类灯具,门,窗帘等家居用品的一种新型智能开关,可对室内一个或者多个灯具的控制,本产品依据国际电工惯例,并采用国内外最先进的电子线路设计,性能稳定可靠. 开关面板符合国家:GB16915.1-1997和GB2099.1-1996标准;产品能通过3C中国国家强制性产品证.

能君隶3049380v交流接触器线圈如何接线 -
索毛芬13414002735 ______ 直接接到380V电源上接触器就可以吸合了

能君隶3049cjx2 - 3210接触器380v是怎么接线的 -
索毛芬13414002735 ______ 你好,cjx2-3210辅助触点为一常开,如果接一个自保电路,可以满足控制要求. 接线方式如下. 以线圈电压380V为例,热继电器常闭一头接电源(L1),常闭输出接停止按钮,停止按钮输出接启动按钮,在引一根自锁线到接触器常开输入,常开输出接线圈A2,线圈A2接L2线. 启动输出接线圈A1. 如果需要加指示灯,把电源指示灯直接并联到电源上,工作指示灯直接并联到接触器线圈上. 希望能帮到你.

能君隶3049380伏60安的接触器怎么接线的!有那位师傅可以教教我, -
索毛芬13414002735 ______ 接触器最少有线圈两个接线端,主回路常开触点三组六个端子(三进三出),你是380V的,那线圈的接线就得是380V电源来提供,主回路的触头一端接电源,另一端接负载.

能君隶3049CJT1 - 10 交流接触器接线图只要最简单的吸合就行了 -
索毛芬13414002735 ______ 这个是380V的接触器线圈,所以用到了一相电源,即二根火线,绿色按钮那边左边出来是接到停止按钮再进断路器,最后接上一路电源,另一路呢是在接触器上最左边的那根从断路器上下来的红色线又引一根下来到了线圈,线圈的另一头在接触器的下面,一根到启动按钮的那里,懂的人一看就知道,这是最基本的,不需要什么N线,这是最简单的图.
