变压器参数及型号大全一览 变压器bian ya qi利用电磁感应的原理来改变交流电压的装置，变压器研究报告指出：主要构件是初级线圈、次级线圈和铁心(磁芯)。在电器设备和无线电路中，常用作升降电压、匹配阻抗，安全隔离等。下面来看看变压器参数。 1 额定容量se：指变压器在出厂时铭牌标定的额定电压、额定电流下连续运行时能输送的容量,单位kva。其计算公式为： 三相变压器se=1.732ueie 单相变压器量se=ueie 2、额定电压ue“指变压器长时间运行时所能承受的工作电压(铭牌上的ue值,是指调压分接开关在中间分头时的额定电压);单位为kv。 3、额定电流ie：在额定容量se和允许温升条件下,允许长期通过的工作电流,单位为a。 4、短路电压ud%：也称阻抗电压(uk%),将变压器的二次绕组短路,一次侧施加电压,至额定电流值时,原边的电压和额定电压ue之比的百分数。即：ud%=ud/ue;100%
变压器的并列运行要求ud%值相同,当变压器二次侧短咱时,ud%值将决定短路电流大小,所以是考虑短路电流热稳定和动稳定及继电保护整定的重要依据。 5、空载电流i。;当变压器在一次侧额定电压下,二次侧绕组空载时,在一次绕组中通过的电流,称空载电流。它起变压器的激磁作用,故又称激磁电流;一般以其占额定电流的百分数表示。空载电流的大小决定于变压器容量、磁路结构和硅钢片质量等。 6、空载损耗(铁损)δp0：指变压器二次侧开路,一次侧加额定电压时,变压器的损耗。它等于变压器铁芯的涡流损耗和激磁损耗,是变压器的重要性能指标。 7、短路损耗(铜损)δpd：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。 8、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
