电子镇流器介绍

电(dian)子(zi)镇流(liu)(liu)器(qi)(qi)（ballast）又称(cheng)电(dian)感(gan)镇流(liu)(liu)器(qi)(qi)，它是(shi)一(yi)个铁(tie)芯电(dian)感(gan)线(xian)圈，电(dian)感(gan)的(de)性质是(shi)当线(xian)圈中(zhong)(zhong)的(de)电(dian)流(liu)(liu)发生变化时，则在(zai)线(xian)圈中(zhong)(zhong)将(jiang)引起磁(ci)通的(de)变化，从而(er)(er)产(chan)生感(gan)应(ying)电(dian)动势，其方向与电(dian)流(liu)(liu)的(de)方向相反，因而(er)(er)阻(zu)碍着电(dian)流(liu)(liu)变化。在(zai)日光灯中(zhong)(zhong)用到(dao)。镇流(liu)(liu)器(qi)(qi)可(ke)以由电(dian)阻(zu)、电(dian)感(gan)、电(dian)容和漏(lou)磁(ci)变压(ya)器(qi)(qi)等独立组成，也可(ke)以由这些(xie)器(qi)(qi)件或由电(dian)子(zi)元件等组合而(er)(er)成。镇流(liu)(liu)器(qi)(qi)在(zai)实际应(ying)用中(zhong)(zhong)，其功能(neng)已不仅局限于镇流(liu)(liu)器(qi)(qi)本身(shen)，还常将(jiang)电(dian)路中(zhong)(zhong)所需的(de)其他功能(neng)或装置，都包含(han)于镇流(liu)(liu)器(qi)(qi)之(zhi)中(zhong)(zhong)。

电(dian)(dian)子(zi)(zi)镇(zhen)流器(qi)（Electronic ballast），是镇(zhen)流器(qi)的一种，是指采用电(dian)(dian)子(zi)(zi)技术(shu)驱动电(dian)(dian)光源，使之(zhi)产生(sheng)所需照(zhao)明的电(dian)(dian)子(zi)(zi)设备。与(yu)之(zhi)对应的是电(dian)(dian)感(gan)式(shi)镇(zhen)流器(qi)（或镇(zhen)流器(qi)）。现代日光灯越(yue)来(lai)越(yue)多的使用电(dian)(dian)子(zi)(zi)镇(zhen)流器(qi)，轻便小(xiao)巧，甚(shen)至(zhi)可(ke)以将电(dian)(dian)子(zi)(zi)镇(zhen)流器(qi)与(yu)灯管等(deng)集成在一起，同(tong)时，电(dian)(dian)子(zi)(zi)镇(zhen)流器(qi)通常可(ke)以兼具启(qi)辉器(qi)功能(neng)，故此又可(ke)省去单独的启(qi)辉器(qi)。电(dian)(dian)子(zi)(zi)镇(zhen)流器(qi)还可(ke)以具有更多功能(neng)，比如可(ke)以通过提高电(dian)(dian)流频率或者电(dian)(dian)流波形（如变(bian)成方波）改善或消除(chu)日光灯的闪烁现象；也可(ke)通过电(dian)(dian)源逆变(bian)过程使得日光灯可(ke)以使用直流电(dian)(dian)源。

电子镇流器接线图方法与步骤

镇流器(qi)的左侧也就是(shi)橘(ju)色的接口就是(shi)零线(xian)和火线(xian)还(hai)有地线(xian)了(le)(le)，这个就不用我说了(le)(le)吧

一端2个接(jie)线，是接(jie)民用电220交流的(de)。就是往电线上接(jie)，没有(you)正负区分。

一端(duan)4个接(jie)线(xian)，是接(jie)2跟灯(deng)管的(de)，灯(deng)管坐上(shang)应该有(you)线(xian)。也没有(you)正负区分。如(ru)果(guo)你只接(jie)一跟灯(deng)管，只用在一起的(de)两根接(jie)上(shang)就(jiu)行了。

电子镇流器接线注意事项

1、先用电(dian)笔(bi)测(ce)试正负极；

2、电工胶(jiao)要扎(zha)牢固，避免漏电。

日光灯电子镇流器接线图及其工作原理介绍

日(ri)光(guang)(guang)(guang)(guang)灯(deng)电子(zi)镇(zhen)(zhen)流(liu)(liu)(liu)器(qi)(qi)(qi)是我们(men)日(ri)常工(gong)作(zuo)生(sheng)活的(de)(de)日(ri)常照(zhao)明工(gong)具，给我们(men)的(de)(de)生(sheng)活带(dai)来光(guang)(guang)(guang)(guang)明和(he)方便。几(ji)乎没有(you)人不(bu)知(zhi)(zhi)道(dao)日(ri)光(guang)(guang)(guang)(guang)灯(deng)，但(dan)却有(you)很多人不(bu)知(zhi)(zhi)道(dao)和(he)日(ri)光(guang)(guang)(guang)(guang)灯(deng)配(pei)套工(gong)作(zuo)的(de)(de)一(yi)个产品—镇(zhen)(zhen)流(liu)(liu)(liu)器(qi)(qi)(qi)。现在使用(yong)的(de)(de)基本上是都是电感镇(zhen)(zhen)流(liu)(liu)(liu)器(qi)(qi)(qi)。小编知(zhi)(zhi)道(dao)，日(ri)光(guang)(guang)(guang)(guang)灯(deng)电子(zi)镇(zhen)(zhen)流(liu)(liu)(liu)器(qi)(qi)(qi)与日(ri)光(guang)(guang)(guang)(guang)灯(deng)必(bi)须要配(pei)套使用(yong)，它可以保证日(ri)光(guang)(guang)(guang)(guang)灯(deng)能(neng)正常点燃，并(bing)达到(dao)各项性(xing)能(neng)指标开始(shi)工(gong)作(zuo)。今天大(da)家就和(he)小编一(yi)起来了解镇(zhen)(zhen)流(liu)(liu)(liu)器(qi)(qi)(qi)工(gong)作(zuo)的(de)(de)原理及接线图。

大多数气体(ti)放电(dian)(dian)(dian)(dian)(dian)(dian)灯是利用弧光放电(dian)(dian)(dian)(dian)(dian)(dian)特性(xing)(xing)制成的(de)，具有电(dian)(dian)(dian)(dian)(dian)(dian)压(ya)随电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)增加而下(xia)降的(de)负(fu)特性(xing)(xing)（又(you)称负(fu)阻特性(xing)(xing)），不可能建立稳定的(de)工作点。为了使放电(dian)(dian)(dian)(dian)(dian)(dian)稳定，限制灯工作电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，必须在气体(ti)放电(dian)(dian)(dian)(dian)(dian)(dian)光源(yuan)电(dian)(dian)(dian)(dian)(dian)(dian)路中设置镇流(liu)(liu)器。镇流(liu)(liu)器已成为气体(ti)放电(dian)(dian)(dian)(dian)(dian)(dian)光源(yuan)电(dian)(dian)(dian)(dian)(dian)(dian)路中重要(yao)的(de)附(fu)加装置。使用半(ban)导体(ti)电(dian)(dian)(dian)(dian)(dian)(dian)子元件(jian)，将直(zhi)流(liu)(liu)或低(di)频交(jiao)流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)压(ya)转换成高频交(jiao)流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)压(ya)，驱动低(di)压(ya)气体(ti)放电(dian)(dian)(dian)(dian)(dian)(dian)灯、卤钨灯等光源(yuan)工作的(de)电(dian)(dian)(dian)(dian)(dian)(dian)子控(kong)制装置。应用最广的(de)是荧光灯电(dian)(dian)(dian)(dian)(dian)(dian)子镇流(liu)(liu)器。

（一）日光灯电感镇流器工作原理及接线图

（1）当送出交流(liu)(liu)电(dian)时(shi)，因荧光灯(deng)(deng)属于冷灯(deng)(deng)，灯(deng)(deng)管电(dian)阻(zu)无穷(qiong)大(da)，大(da)电(dian)流(liu)(liu)就(jiu)流(liu)(liu)向阻(zu)抗比(bi)较小的启(qi)动器，因此(ci)氖(nai)灯(deng)(deng)会先亮一下子(zi)与电(dian)容形(xing)成崩溃，此(ci)时(shi)电(dian)流(liu)(liu)流(liu)(liu)过(guo)灯(deng)(deng)管两端的钨丝，钨丝因此(ci)被加热，这段时(shi)间(jian)为(wei)0至(zhi)A的时(shi)间(jian)。

（2）当(dang)时(shi)(shi)间在(zai)A时(shi)(shi)即(ji)电(dian)源电(dian)压为零伏(fu)，由于日(ri)光(guang)灯(deng)(deng)此(ci)(ci)时(shi)(shi)已为热灯(deng)(deng)，使(shi)得灯(deng)(deng)管内电(dian)阻相当(dang)小，此(ci)(ci)时(shi)(shi)启动器部分停(ting)止崩(beng)溃，接(jie)着时(shi)(shi)间A至时(shi)(shi)间B荧光(guang)灯(deng)(deng)点灯(deng)(deng)成(cheng)功(gong)，并且时(shi)(shi)间B以后(hou)萤(ying)(ying)光(guang)灯(deng)(deng)两端的压降(jiang)大约只有(you)122伏(fu)特左右（20W萤(ying)(ying)光(guang)灯(deng)(deng)），使(shi)启动器不再(zai)崩(beng)溃，从(cong)此(ci)(ci)之后(hou)日(ri)光(guang)灯(deng)(deng)正常工作维(wei)持一定亮度，直到电(dian)源关闭(bi)日(ri)光(guang)灯(deng)(deng)熄灭。

（3）在时间A至时间B，电(dian)(dian)感镇流器(qi)（电(dian)(dian)感）两端(duan)感应(ying)电(dian)(dian)压(ya)为220伏，再(zai)加上电(dian)(dian)源220伏，其萤(ying)光灯(deng)两端(duan)总电(dian)(dian)压(ya)降为440伏，所(suo)以萤(ying)光灯(deng)需要大电(dian)(dian)压(ya)才能启动。

（4）在(zai)时间B之(zhi)后，电感式镇流器(qi)（电感）扮演着恒流的重要角色，所以日光(guang)灯(deng)一直维持着固定的亮度。

（二）工作原理

当开关接通的(de)时候，电(dian)(dian)(dian)源电(dian)(dian)(dian)压立即(ji)(ji)通过镇流器(qi)和灯管灯丝加(jia)到启(qi)辉(hui)(hui)器(qi)的(de)两极.220伏的(de)电(dian)(dian)(dian)压立即(ji)(ji)使(shi)启(qi)辉(hui)(hui)器(qi)的(de)惰性(xing)气体电(dian)(dian)(dian)离，产生辉(hui)(hui)光放电(dian)(dian)(dian)。

这个过(guo)程的热(re)量使(shi)双(shuang)金属片(pian)受热(re)膨胀，因为(wei)动(dong)(dong)静触片(pian)的膨胀程度(du)不同，U形动(dong)(dong)触片(pian)膨胀伸长，与静触片(pian)接触而接通电路，于是镇流器的两(liang)极(ji)接触。电流通过(guo)镇流器、启(qi)辉(hui)器触极(ji)和(he)两(liang)端灯(deng)丝构成通路。这时，由(you)于启(qi)辉(hui)器两(liang)极(ji)闭合，两(liang)极(ji)间电压(ya)为(wei)零，启(qi)动(dong)(dong)器中的氖(nai)气停止导(dao)电，辉(hui)光放电消(xiao)失，导(dao)致管内温(wen)度(du)下(xia)降(jiang)，U形动(dong)(dong)触片(pian)冷却(que)收缩，两(liang)触片(pian)分离，电路自动(dong)(dong)断(duan)开。

在(zai)两极(ji)断(duan)开的(de)(de)瞬间(jian)，电(dian)(dian)(dian)路电(dian)(dian)(dian)流突然切断(duan)，镇流器产(chan)生很大的(de)(de)自感(gan)电(dian)(dian)(dian)动(dong)势，与电(dian)(dian)(dian)源电(dian)(dian)(dian)压(ya)叠加后作(zuo)(zuo)用于管两端。灯丝受(shou)热(re)时发(fa)(fa)射出来的(de)(de)大量电(dian)(dian)(dian)子(zi)，在(zai)灯管两端高电(dian)(dian)(dian)压(ya)作(zuo)(zuo)用下，以极(ji)大的(de)(de)速(su)(su)度由低电(dian)(dian)(dian)势端向高电(dian)(dian)(dian)势端运(yun)动(dong)。在(zai)加速(su)(su)运(yun)动(dong)的(de)(de)过程中(zhong)，碰撞管内氩(ya)气(qi)分子(zi)，使之(zhi)(zhi)迅速(su)(su)电(dian)(dian)(dian)离。氩(ya)气(qi)电(dian)(dian)(dian)离生热(re)，热(re)量使水银产(chan)生蒸气(qi)，随之(zhi)(zhi)水银蒸气(qi)也被电(dian)(dian)(dian)离，并发(fa)(fa)出强烈(lie)的(de)(de)紫(zi)外线(xian)。

在紫外线的(de)激发(fa)下，管(guan)壁内的(de)荧光粉发(fa)出(chu)近乎白色的(de)可见(jian)光。日光灯(deng)正(zheng)常(chang)发(fa)光后。由于交流(liu)(liu)电(dian)不(bu)断(duan)通过镇流(liu)(liu)器(qi)的(de)线圈，线圈中(zhong)产生自感(gan)电(dian)动(dong)势，自感(gan)电(dian)动(dong)势阻(zu)碍线圈中(zhong)的(de)电(dian)流(liu)(liu)变化，这时镇流(liu)(liu)器(qi)起降压(ya)(ya)限流(liu)(liu)的(de)作(zuo)用(yong)，使电(dian)流(liu)(liu)稳定在灯(deng)管(guan)的(de)额(e)定电(dian)流(liu)(liu)范(fan)围(wei)内，灯(deng)管(guan)两(liang)端电(dian)压(ya)(ya)也稳定在额(e)定工作(zuo)电(dian)压(ya)(ya)范(fan)围(wei)内。

日光灯镇流器(qi)接线图有(you)(you)很多种，主要区别在(zai)于电(dian)路本身的(de)(de)(de)结构还(hai)有(you)(you)房子里的(de)(de)(de)结构。镇流器(qi)应该(gai)符(fu)合国际(ji)上的(de)(de)(de)各种标(biao)准，比如额定电(dian)流电(dian)压(ya)以及电(dian)压(ya)变化的(de)(de)(de)范围。有(you)(you)时候家(jia)里的(de)(de)(de)日光灯忽(hu)然不亮了，有(you)(you)可能是镇流器(qi)出现故障了，此时应该(gai)找专(zhuan)业(ye)的(de)(de)(de)电(dian)工过来家(jia)里面(mian)维(wei)修。建议(yi)，如(ru)果要(yao)自(zi)己亲自(zi)维修电(dian)器(qi)，可以先关闭电(dian)源，请注意自(zi)身的安全(quan)。
