变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器是一(yi)(yi)种电(dian)(dian)力设(she)备(bei)，主要用于(yu)改(gai)变(bian)(bian)(bian)(bian)交流(liu)(liu)电(dian)(dian)的(de)电(dian)(dian)压(ya)(ya)(ya)和(he)电(dian)(dian)流(liu)(liu)大小。它由(you)两个或(huo)(huo)更多的(de)线(xian)圈(quan)(quan)（称为原(yuan)线(xian)圈(quan)(quan)和(he)次级线(xian)圈(quan)(quan)）组成(cheng)，它们(men)通过一(yi)(yi)个铁(tie)芯相(xiang)连。当原(yuan)线(xian)圈(quan)(quan)中(zhong)通电(dian)(dian)时(shi)，它会产(chan)生(sheng)一(yi)(yi)个磁(ci)场(chang)，这(zhei)个磁(ci)场(chang)会在(zai)铁(tie)芯中(zhong)感(gan)应出一(yi)(yi)个电(dian)(dian)流(liu)(liu)，从而使次级线(xian)圈(quan)(quan)中(zhong)也产(chan)生(sheng)电(dian)(dian)流(liu)(liu)。变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器的(de)工作原(yuan)理基于(yu)法拉第电(dian)(dian)磁(ci)感(gan)应定(ding)律，即在(zai)变(bian)(bian)(bian)(bian)化的(de)磁(ci)场(chang)中(zhong)会产(chan)生(sheng)电(dian)(dian)动势。通过改(gai)变(bian)(bian)(bian)(bian)原(yuan)线(xian)圈(quan)(quan)和(he)次级线(xian)圈(quan)(quan)的(de)匝(za)数比例，变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器可以将电(dian)(dian)压(ya)(ya)(ya)从高压(ya)(ya)(ya)降到低压(ya)(ya)(ya)或(huo)(huo)从低压(ya)(ya)(ya)升到高压(ya)(ya)(ya)。变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器广泛应用于(yu)电(dian)(dian)力输配电(dian)(dian)、电(dian)(dian)子设(she)备(bei)、通讯系(xi)统等(deng)领(ling)域。中(zhong)山直销变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器制造厂(chang)家贴片(pian)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器通常由(you)两个或(huo)(huo)多个单独的(de)线(xian)圈(quan)(quan)组成(cheng)，通过电(dian)(dian)磁(ci)感(gan)应的(de)原(yuan)理来实现电(dian)(dian)能的(de)变(bian)(bian)(bian)(bian)换。

变(bian)(bian)(bian)压(ya)器(qi)(qi)的(de)铁(tie)损包括两个方面。一(yi)是(shi)磁滞(zhi)(zhi)损耗，当交流(liu)(liu)电流(liu)(liu)通过变(bian)(bian)(bian)压(ya)器(qi)(qi)时(shi)(shi)，通过变(bian)(bian)(bian)压(ya)器(qi)(qi)硅(gui)钢(gang)(gang)片的(de)磁力(li)线其方向和大小(xiao)随之(zhi)变(bian)(bian)(bian)化，使得硅(gui)钢(gang)(gang)片内部分(fen)子(zi)相(xiang)互摩擦，放(fang)出(chu)热能，从而损耗了一(yi)部分(fen)电能，这(zhei)便是(shi)磁滞(zhi)(zhi)损耗。另(ling)一(yi)是(shi)涡(wo)(wo)流(liu)(liu)损耗，当变(bian)(bian)(bian)压(ya)器(qi)(qi)工作(zuo)时(shi)(shi)。铁(tie)芯中有磁力(li)线穿过，在与磁力(li)线垂直的(de)平面上就(jiu)会产生感应电流(liu)(liu)，由于此电流(liu)(liu)自成闭合(he)回路形成环流(liu)(liu)，且成旋涡(wo)(wo)状，故称为(wei)(wei)涡(wo)(wo)流(liu)(liu)。涡(wo)(wo)流(liu)(liu)的(de)存(cun)在使铁(tie)芯发热，消耗能量，这(zhei)种损耗称为(wei)(wei)涡(wo)(wo)流(liu)(liu)损耗。变(bian)(bian)(bian)压(ya)器(qi)(qi)的(de)效(xiao)率(lv)与变(bian)(bian)(bian)压(ya)器(qi)(qi)的(de)功率(lv)等级有密(mi)切关系，通常功率(lv)越(yue)大，损耗与输出(chu)功率(lv)比就(jiu)越(yue)小(xiao)，效(xiao)率(lv)也就(jiu)越(yue)高。反之(zhi)，功率(lv)越(yue)小(xiao)，效(xiao)率(lv)也就(jiu)越(yue)低。

变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)原理电(dian)压(ya)(ya)(ya)比(bi)(bi)：变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)两(liang)组线(xian)圈(quan)(quan)(quan)圈(quan)(quan)(quan)数分别(bie)为(wei)(wei)(wei)(wei)(wei)N1和N2，N1为(wei)(wei)(wei)(wei)(wei)初级(ji)，N2为(wei)(wei)(wei)(wei)(wei)次级(ji)。在(zai)初级(ji)线(xian)圈(quan)(quan)(quan)上(shang)加(jia)一交(jiao)流电(dian)压(ya)(ya)(ya)，在(zai)次级(ji)线(xian)圈(quan)(quan)(quan)两(liang)端就会产(chan)生感(gan)应(ying)电(dian)动势(shi)。当N2>N1 时，其(qi)感(gan)应(ying)电(dian)动势(shi)要比(bi)(bi)初级(ji)所加(jia)的(de)(de)电(dian)压(ya)(ya)(ya)还(hai)要高，这(zhei)种(zhong)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)称(cheng)为(wei)(wei)(wei)(wei)(wei)升压(ya)(ya)(ya)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)：当N2式中n 称(cheng)为(wei)(wei)(wei)(wei)(wei)电(dian)压(ya)(ya)(ya)比(bi)(bi)(圈(quan)(quan)(quan)数比(bi)(bi)) 。当n<1 时，则(ze)N1>N2 ，U1>U2 ，该变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)为(wei)(wei)(wei)(wei)(wei)降压(ya)(ya)(ya)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)。反(fan)之则(ze)为(wei)(wei)(wei)(wei)(wei)升压(ya)(ya)(ya)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)。变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)效率(lv)(lv)：在(zai)额定功(gong)(gong)率(lv)(lv)时，变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)输出功(gong)(gong)率(lv)(lv)和输入功(gong)(gong)率(lv)(lv)的(de)(de)比(bi)(bi)值(zhi)，叫做(zuo)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)效率(lv)(lv)，即 式中η 为(wei)(wei)(wei)(wei)(wei)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)效率(lv)(lv)；P1为(wei)(wei)(wei)(wei)(wei)输入功(gong)(gong)率(lv)(lv)，P2为(wei)(wei)(wei)(wei)(wei)输出功(gong)(gong)率(lv)(lv)。当变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)输出功(gong)(gong)率(lv)(lv)P2等于输入功(gong)(gong)率(lv)(lv)P1时，效率(lv)(lv)η等于100%，变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)将(jiang)不产(chan)生任何损耗。但(dan)实(shi)际(ji)上(shang)这(zhei)种(zhong)变(bian)(bian)(bian)(bian)压(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)是没(mei)有的(de)(de)。安(an)装(zhuang)方式简(jian)单，可以通过自(zi)动化设备进行快(kuai)速安(an)装(zhuang)。

插件(jian)(jian)变(bian)压(ya)器(qi)(qi)是一种(zhong)特(te)殊的(de)(de)(de)(de)(de)(de)电(dian)(dian)力设(she)(she)备(bei)，其(qi)(qi)(qi)体(ti)积小(xiao)、重(zhong)量轻(qing)、功率(lv)密(mi)度(du)高(gao)(gao)的(de)(de)(de)(de)(de)(de)特(te)点使(shi)其(qi)(qi)(qi)在当今高(gao)(gao)度(du)微型化(hua)和(he)(he)集成(cheng)(cheng)化(hua)的(de)(de)(de)(de)(de)(de)应用(yong)场景中占有重(zhong)要地位。与(yu)传统(tong)的(de)(de)(de)(de)(de)(de)变(bian)压(ya)器(qi)(qi)相比，插件(jian)(jian)变(bian)压(ya)器(qi)(qi)在设(she)(she)计(ji)上更(geng)具(ju)创(chuang)新，能够有效地减少空(kong)间占用(yong)和(he)(he)重(zhong)量，同(tong)时提高(gao)(gao)功率(lv)密(mi)度(du)，使(shi)得在有限的(de)(de)(de)(de)(de)(de)空(kong)间内(nei)能够提供更(geng)大的(de)(de)(de)(de)(de)(de)电(dian)(dian)力输出。这种(zhong)变(bian)压(ya)器(qi)(qi)的(de)(de)(de)(de)(de)(de)使(shi)用(yong)非常广，特(te)别是在需要高(gao)(gao)功率(lv)、小(xiao)体(ti)积、轻(qing)质量的(de)(de)(de)(de)(de)(de)电(dian)(dian)子(zi)设(she)(she)备(bei)中，例如电(dian)(dian)动汽(qi)车、航天器(qi)(qi)、医疗(liao)设(she)(she)备(bei)和(he)(he)许多(duo)(duo)(duo)其(qi)(qi)(qi)他(ta)高(gao)(gao)科(ke)技应用(yong)领(ling)(ling)域(yu)。其(qi)(qi)(qi)高(gao)(gao)功率(lv)密(mi)度(du)可(ke)以增加设(she)(she)备(bei)的(de)(de)(de)(de)(de)(de)性(xing)能，同(tong)时降(jiang)低冷却需求，提高(gao)(gao)设(she)(she)备(bei)的(de)(de)(de)(de)(de)(de)效率(lv)和(he)(he)可(ke)靠性(xing)。此外，插件(jian)(jian)变(bian)压(ya)器(qi)(qi)的(de)(de)(de)(de)(de)(de)设(she)(she)计(ji)也有助于减少电(dian)(dian)磁干扰，提高(gao)(gao)电(dian)(dian)力转(zhuan)换效率(lv)，从而降(jiang)低能耗。总的(de)(de)(de)(de)(de)(de)来说，插件(jian)(jian)变(bian)压(ya)器(qi)(qi)以其(qi)(qi)(qi)出色的(de)(de)(de)(de)(de)(de)性(xing)能和(he)(he)很多(duo)(duo)(duo)的(de)(de)(de)(de)(de)(de)应用(yong)领(ling)(ling)域(yu)，成(cheng)(cheng)为现代(dai)电(dian)(dian)力设(she)(she)备(bei)中不可(ke)或(huo)缺的(de)(de)(de)(de)(de)(de)一部分。贴(tie)片变(bian)压(ya)器(qi)(qi)的(de)(de)(de)(de)(de)(de)使(shi)用(yong)寿命主要受(shou)到绕线材料、绝缘(yuan)材料和(he)(he)使(shi)用(yong)环境等多(duo)(duo)(duo)种(zhong)因素的(de)(de)(de)(de)(de)(de)影响。汕头定制变(bian)压(ya)器(qi)(qi)厂商
