1、导读：能源是社会发展与进步的物质基础。随着社会的发展，人类生活水平的提高，人类对电力能源的消费量也越来越大。根据用途不同，变压器可以分为电力变压器、仪用变压器、整流变压器和试验变压器等八个不同的种类。那您了解变压器型号、变压器原理以及变压器的作用吗？众所周知，电从发电机发出来以后，通过升压变压器送到电网，再经过几级降低电压后才送到用户，期间共通过变压器 4 到 5 次，甚至 8-9 次。所以一般每 1KW 的发电设备就相应需要 5-9KVA 的变压器。今天，将为您介绍变压器型号、变压器原理以及变压器的作用，使您能够更深入地了解变压器一、变压器型号变压器型号是指用英文字母组合与一个或几个数字来表

3、由变压器型号表中可查得该变压器为三相（S ）干式（G）额定容量为 6 千伏安。例如有台 ZSG 变压器，由变压器型号表中可查得该变压器为三相（S）干式（G）整流变压器（Z）系列。3.电力变压器型号及意义电力变压器DSCGJFSFPSPSLZTDHQ单相三相浇注绝缘干式空气自冷干式油浸风冷水冷强油风冷强油水冷三绕组铝线有载成套移动式防火干式干式加强例如有台电力变压器 SJL-560/10，由电力变压器表中可查得该变压器为三相油浸自冷式铝线 560 千伏安、高压侧电压 10 千伏。4.自耦变压器型号及意义：自耦变压器OS、 D、J、F 、FP、Z自耦（注：O 在前为降压，O 在后为升压）同电力5.
4、电炉变压器型号及意义电炉变压器HKS、J 、FP、SP电炉附电抗器同电力6.低压变压器型号及意义：低压变压器DSD、J低电压水冷同电力二、变压器原理变压器是根据电磁感应原理（即电能和磁能在一定条件下可以互相转换的原理）制成的。变压器是用来改变交流电流、电流和阻抗的电气设备。它可以把高电压变成低电压，也可以把低电压变成高电压。三、变压器的作用电力变压器在向远距离输电时，如输送电功率一定时，电压越低，电流就越大，导线的截面就越大，线路铺设费用也越高；若用升压变压器把电压提高，则线路中电流便可减少，费用也随之减低。高电压输送到用户中心后还需用降压变压器把高电压降低到各种不同的电压，以供用户使用。因此
