摘 要
随着我国经济建设的发展，电力工业规模迅速的壮大起来，电源变压器的单台容量和安装容量快速增长。国际巨头强势参加海内市场竞争的面前，一方面看中的是我国电力设备市场的伟大后劲；另一方面，也表现了中国企业长足的进步，尤其在质量方面，国产电力变压器已经越来越靠近海内程度，使得海内巨头们不得不拿出“看家身手”逐鹿中国市场。
变压器是一种用于交流电能转换的电气设备。它可以把一种交流电压、交流电流的电能转换成相同频率的另一种交流电压、交流电流的电能。变压器在电力系统中的主要作用是变换电压,以利于电能的传输。电压经升压变压器升压后,可以减少线路损耗,提高送电经济性,达到远距离送电的目的。电压经降压变压器降压后,获得各级用电设备的所需电压,以满足用户使用的需要。
电源变压器，一种运动的电气设备，是用来将某一数值的交换电压(电流)变成频率雷同的另一种或几种数值不同的电压(电流)的设备。
据理解，占有世界技巧制高点变压器行业重要看两项数字，产品容量与电压等级。早在“十一五”初期，我国就已是世界上电力变压器的消费和运用大国，但并不是强国。事先，海内仅有多数企业能消费500千伏的超低压变压器，超低压变压器的市场份额基础被国外巨头垄断。随着海内首条特低压实验示范工程的下马，海内变压器企业迎来了开展契机，产品电压等级和容量一举跃居世界第一，占有了行业开展的技巧制高点，同时，匆匆进了低电压等级变压器技巧的始终成熟和完美。
本文简要分析了电源变压器的设计。所谓的电源变压器是电源变压器的功能是功率传送、电压变换和绝缘隔离，作为一种主要的软磁电磁元件，在电源技术中和电力电子技术中得到广泛的应用。有人根据它的主要功能是功率传送，把英文名称“Power Transformers”译成“电力变压器”，在许多文献资料中仍然在使用。

Abstract
With the development of economy in China, the power industry scale rapid expansion, the single power transformer capacity and installed capacity of rapid growth. International tycoon is strong in the domestic market competition before, one hand look is China power equipment market and great potential; on the other hand, also reflects the Chinese enterprise great progress, especially in the aspect of quality, the domestic electric power transformer has been more and more close to the domestic level, making the domestic giants had to come up with a \market.
Transformer is a kind of alternating current energy conversion for electric equipment. It can be an AC voltage, AC current of the electric energy is converted into the same frequency of another kind of alternating voltage, alternating current electrical energy. Transformer in power system 's primary role is to transform voltage, in order to facilitate the electrical energy transmission. Voltage step-up transformer, can reduce the line loss, improve transmission economy, achieve the purpose of long distance power transmission. Voltage step-down transformer step-down, access to all levels of electrical equipment voltage required to satisfy the user needs.
Power transformer, a movement of the electrical equipment, is to be used for a number of switching voltage ( current) into a frequency the same one or several different voltage ( current) equipment.
According to understanding, occupy world skill commanding elevation transformer industry important two digital, product capacity and voltage grade. As early as in the\our country already was the world power transformer production and use big country, but not be powerful nation. Previously, the domestic only most enterprise can consume 500000volt ultra low voltage transformer, voltage transformer market share basis by foreign giants monopoly. As China's first special low-pressure experimental demonstration project to dismount, domestic transformer manufacturers welcomed development opportunity, the product of voltage and volume in one fell swoop jumps house world the first, occupy the industry to carry out skill commanding elevation, at the same time, hurried into the low voltage transformer skills always ripe and perfect.
