中间继电器在实际应用中的2个基本作用

2021.01.03 浏览量: 字号:

中间继电器在实际应用中的2个基本作用:

1、中间继电器触点扩展,一般用在主回路居多:

例如:中(zhong)间继电器(qi)(qi)用在(zai)主(zhu)回(hui)路(lu)中(zhong),和交流接触器(qi)(qi)并联,用来扩展交流接触器(qi)(qi)的触点,弥(mi)补触点使用情况不足的缺(que)点。

2、进行电气隔离一般多应用于控制电路中:

就是我们平常使(shi)用的原(yuan)理:小电流来控(kong)制(zhi)大(da)(da)电流,小电压(ya)来控(kong)制(zhi)大(da)(da)电压(ya),对于主回(hui)路中(zhong)大(da)(da)电流和大(da)(da)电压(ya)进行隔离。

中间继(ji)电器我们看图中这款(kuan),13---14 电源接线,1--5---9 ,9----5 常(chang)开点(dian),1--9常(chang)闭(bi)点(dian)。

同样的4---8---12=4---12常闭点(dian)。8----12常开点(dian)。

中间继(ji)电(dian)(dian)(dian)器实物运用(yong):如何用(yong)微型继(ji)电(dian)(dian)(dian)器控(kong)制负载,图中我(wo)们(men)用(yong)继(ji)电(dian)(dian)(dian)器控(kong)制一盏灯(deng),13---14 接入电(dian)(dian)(dian)源(yuan),零(ling)线直接进灯(deng),火线进继(ji)电(dian)(dian)(dian)器常(chang)开点9,经过常(chang)开点出来就是5,接到灯(deng)上面,当继(ji)电(dian)(dian)(dian)器通电(dian)(dian)(dian)的(de)时候常(chang)开触点闭合,灯(deng)得电(dian)(dian)(dian)亮起来。

继(ji)(ji)电(dian)器(qi)(qi)(qi)常(chang)开---常(chang)闭运用=13---14接继(ji)(ji)电(dian)器(qi)(qi)(qi)电(dian)源(yuan),零(ling)线分(fen)别进(jin)(jin)(jin)两(liang)个(ge)灯(deng),火线进(jin)(jin)(jin)继(ji)(ji)电(dian)器(qi)(qi)(qi)公共端(duan)(duan)9,然后5出(chu)来进(jin)(jin)(jin)灯(deng),1号(hao)端(duan)(duan)子出(chu)来进(jin)(jin)(jin)灯(deng),微型(xing)继(ji)(ji)电(dian)器(qi)(qi)(qi)初始状态1号(hao)端(duan)(duan)子上面的灯(deng)会亮(liang)(liang)起来,因(yin)为1---9是常(chang)闭点(dian),继(ji)(ji)电(dian)器(qi)(qi)(qi)得电(dian)吸合(he)5号(hao)接线端(duan)(duan)子灯(deng)会亮(liang)(liang)起来。因(yin)为继(ji)(ji)电(dian)器(qi)(qi)(qi)得电(dian),常(chang)开触点(dian)闭合(he),所以灯(deng)会亮(liang)(liang)起来。
