变压器型号原理及作用
导读：能源是社会开展与进步的物质根底。随着社会的开展，人类生活程度的进步，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。那您理解变压器型号、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，使您可以更深化地理解变压器
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示不同相数、冷却形式、
线圈导线材料、调压方式的符号和变压器额定容量、额定电压、额定电流及连接组标
组成。
1.干式变压器型号及意义：
SC(B)-100/10干式变压器，    sh-jianyi，这就是某款干式变压器的型号，可很多朋友却并不明白它表示的是什么意思。事实上，由上表可查得该变压器为环氧树脂
浇注型干式变压器额定容量100千伏安，额定高压侧电压10千伏〔B：箔式线圈〕
2.整流变压器型号及意义
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
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：
5.电炉变压器型号及意义
6.低压变压器型号及意义：
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
电力变压器在向远间隔输电时，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；假设用升压变压器把电压进步，那么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，变压器是一种非常重要的电气设备。
Abstract: the energy is the material basis for social development and progress. With the development of society, to raise the level of human life, human consumption of electrical energy is more and more big. According to different purposes, the transformer can be divided into power transformer, instrument transformer, rectifier transformers and the transformer eight different species. You know, the principle of transformer and the transformer type transformer action?
As everyone knows, electricity from generators to the grid through a step-up transformer, and then after a few stages, lowering the voltage to the user, during which through the transformer 4 to 5 times, and even 8-9 times. Transformer so power equipment general every 1KW corresponding to 5-9KVA. Today, the transformer model, the principle of transformer and the transformer action for you, so that y
ou can understand the transformer more deeply
One, the transformer model
The transformer model is used English letter combinations with one or a few numbers to represent different phase number, form, cooling coil wire material, voltage regulation, symbols and transformer rated capacity, rated voltage, rated current and the connection group of standard.
Open type dry transformer
SC (B) -100/10 dry type transformer,    sh-jianyi, this is a dry transformer models, but many friends do not understand what it says. In fact, the table of the transformer is casting resin dry-type transformer rated capacity of 100000 ampere, high side voltage of 10000 volts (B: foil coil)
://    sh-jianyi/a/xinwenzixun/gongsidongtai/20211224/104.html
For example, a SG-6KVA rectifier transformer, the transformer models table can check the transformer is a three-phase (S) dry (G) rated capacity of 6000 kva.
For example, ZSG transformer, the transformer models table can check the transformer is a three-phase (S) dry (G) rectifier transformer (Z) series.
变压器的型号The types and significance of the 3 power transformer
For example, a power transformer SJL-560/10 power transformer, the table can check the transformer is a three-phase oil immersed self cooled aluminium 560000 volt ampere, high side voltage of 10000 volts.
4 since the model of transformer:
Two, the principle of transformer
The transformer is according to the principle of electromagnetic induction (i.e. electrical energy principle and magnetic energy can convert each other in certain conditions) made of.
Transformer is the electric equipment used to change the alternating current, current and impedance. It can make the high voltage into low voltage, also can put the low voltage into high voltage.
Three, the role of the transformer
Power transformer in the long distance transmission, such as transmission of electric power, voltage is low, the current is greater, the greater the wire section, line laying cost is higher; if the voltage step-up t
ransformer is improved, in the current line can be reduced, the cost is also reduced. High voltage transmission to the user center also with a step-down transformer high voltage to reduce to a variety of different voltage, available to users. Therefore, a transformer is an important electrical equipment.
