1771-IXE/D
AB1771-IXE/DAB1771-IXE/DAB1771-IXE/D变压器是变换交流电压、电流和阻抗的器件,当初级线圈中通有交流电变压器原理图流时,铁芯(或磁芯)中便产生交流磁通,使次级线圈中感应出电压(或电流)。变压器由铁芯(或磁芯)和线圈组成,线圈有两个或两个以上的绕组,其中接电源的绕组叫初级线圈,其余的绕组叫次级线圈。在发电机中,不管是线圈运动通过磁场或磁场运动通过固定线圈,均能在线圈中感应电势,此两种情况,磁通的值均不变,但与线圈相交链的磁通数量却有变动,这是互感应的原理。变压器就是一种利用电磁互感应,变换电压,电流和阻抗的器件。在额定功率时,变压器的输出功率和输入功率的比值,叫做变压器的效率,即:η=(P2÷P1)x100%式中,η为变压器的效率;P1为输入功率,P2为输出功率。大功率高压配电变压器当变压器的输出功率P2等于输入功率P1时,效率η等于100%,变压器将不产生任何损耗。但实际上这种变压器是没有的。变压器传输电能时总要产生损耗,这种损耗主要有铜损和铁损。铜损是指变压器线圈电阻所引起的损耗.当电流通过线圈电阻发热时,一部分电能就转变为热能而损耗。由于线圈一般都由带绝缘的铜线缠绕而成,因此称为铜损。变压器的铁损包括两个方面:一是磁滞损耗,当交流电流通过变压器时,通过变压器硅钢片的磁力线其方向和大小随之变化,使得硅钢片内部分子相互摩擦,放出热能,从而损耗了一部分电能,这便是磁滞损耗。另一是涡流损耗,当变压器工作时,铁芯中有磁力线穿过,在与磁力线垂直的平面上就会产生感应电流,由于此电流自成闭合回路形成环流,且成旋涡状,故称为涡流。涡流的存在使铁芯发热,消耗能量,这种损耗称为涡流损耗。变压器的效率与变压器的功率等级有密切关系,通常功率越大,损耗与输出功率就越小,效率也就越高。反之,功率越小,效率也就越低。DSQC2563HAB2211-1DSQC256A3HAB2211-13HAB2211-1/03HAB2211-1/13HAB2211-1-1DSQC2573HAA3563-ATADSQC2583HAA3563-AUA3HAA3563-AUA/13HAAA3563-AUA/1DSQC2593HAB2205-1/1DSQC266A3HAB8796-1/2BDSQC266B3HAB8797-1/2BDSQC266C3HAB8798-1/2B3HAB8801-13HAB8801-1/2DSQC266G3HAB8801-1/2BDSQC266T3HAB8802-1/2BDSQC3023HAA3573-ACADSQC3023HAA3573-ACA/3DSQC3033HAA3573-ADADSQC3063HAB2241-13HAA3573-AJADSQC3073HAA3573-AJA/13HAB2213-1/2ABB3HAB2213-1/5DSQC3133HAB3700-1/1DSQC314A3HAB2215-1DSQC314B3HAB2216-1DSQC314CDSQC3153HAB2214-1DSQC3153HAB2214-1/1DSQC3153HAB2214-1/2DSQC317DSQC3173HAB2220-1DSQC320DSQC3203HAB7231-1DSQC3213HAB2236-1DSQC3233HAB5956-1DSQC324DSQC3243HAB5957DSQC3243HAB5957-1DSQC325DSQC3253HAB2241-1DSQC326DSQC3273HAB7203-1DSQC3283HAB7229-1DSQC328A3HAC17970-1DSQC328A3HAC17970-1/03DSQC328A3HAC17970-1/04DSQC3313HAB7215/2-1/03DSQC3313HAB7215-1DSQC3313HAB7215-1DSQC3313HAB7215-1/04DSQC3313HAB7215-1/06DSQC3313HAB7215-1/07DSQC3313HAB7215-1/09DSQC3313HAB7218-1/04DSQC3343HA***45-1/2DSQC335DSQC3353HAB6182-1DSQC336DSQC3363HNE00001DSQC3363HNE00001-1DSQC3363HNE00001-1/07DSQC346G3HAB8101-8DSQC346G3HAB8101-8/08BDSQC350DSQC3503HNE00025DSQC3503HNE00025-1/07DSQC3503HNE00025-1/10DSQC3503HNE00025-1/13DSQC350ADSQC351DSQC355DSQC3553HNE00554-1DSQC355A3HNE00554-1/10DSQC363DSQC369DSQC3C2DSQC504DSQC541DSQS346G3HAC1462-13HAC2424-13HAA3573-ACA/33HAC5689-13HAC14363-13HAB8101-8/08Z)
