变压器主要分类
Main classification of transformer
一般常用变压器的分类可归纳如下：
The general classification of common transformers can be summed up as follows:
1、按相数分：
1. According to the number of phases:
1）单相变压器：用于单相负荷和三相变压器组。
1) single phase transformer: used for single-phase load and three-phase transformer group.
2）三相变压器：用于三相系统的升、降电压。
2) three phase transformer: used for the rise and fall voltage of three-phase system.
2、按冷却方式分：
2, according to the cooling method:
1）干式变压器：依靠空气对流进行自然冷却或增加风机冷却，多用于高层建筑、高速收费站点用电及局部照明、电子线路等小容量变压器。
1) dry type transformer: natural cooling by air convection or increasing fan cooling, which is mostly used in high buildings, high speed charging stations, local lighting, electronic circuits and other small capacity transformers.
2）油浸式变压器：依靠油作冷却介质、如油浸自冷、油浸风冷、油浸水冷、强迫油循环等。
2) oil immersed transformer: rely on oil as cooling medium, such as oil immersed self cooling, oil immersed air cooling, oil immersed water cooling, forced oil circulation, etc.
3、按用途分：
3. According to the use:
1）电力变压器：用于输配电系统的升、降电压。
1) power transformer: used for transmission and distribution systems.
2）仪用变压器：如电压互感器、电流互感器、用于测量仪表和继电保护装置。
2) instrument transformers such as voltage transformers, current transformers, measuring instruments and relay protection devices.
3）试验变压器：能产生高压，对电气设备进行高压试验。
3) test transformer: it can generate high voltage and carry out high voltage test on electrical equipment.
4）特种变压器：如电炉变压器、整流变压器、调整变压器、电容式变压器、移相变压器等。
4) special transformers such as electric furnace transformers, rectifier transformers, regulating transformers, capacitive transformers, phase shifting transformers, etc.
4、按绕组形式分：
4, according to the form of windings:
1）双绕组变压器：用于连接电力系统中的两个电压等级。
1) double winding transformer: used to connect two voltage levels in the power system.
2）三绕组变压器：一般用于电力系统区域变电站中，连接三个电压等级。
2) three winding transformer: generally used in power system substation, connecting three voltage levels.
3）自耦变电器：用于连接不同电压的电力系统。也可做为普通的升压或降后变压器用。
3) autotransformer: a power system that connects different voltages. It can also be used as a common boost or down transformer.
5、按铁芯形式分：
5, according to the form of iron core:
1）芯式变压器：用于高压的电力变压器。
1) core transformer: used for high voltage power transformers.
2）非晶合金变压器：非晶合金铁芯变压器是用新型导磁材料，空载电流下降约80%，是节能效果较理想的配电变压器，特别适用于农村电网和发展中地区等负载率较低地方。
2) amorphous alloy transformer: amorphous alloy iron core transformer is a new type of magnetic conductive material, which reduces the no-load current by about 80%. It is an ideal distribution transformer with energy saving effect. It is especially suitable for the low load rate of rural power grid and developing area.
3）壳式变压器：用于大电流的特殊变压器，如电炉变压器、电焊变压器；或用于电子仪器及电视、收音机等的电源变压器。
3) shell transformer: special transformer used for large current, such as electric furnace transformer, electric welding transformer, or power transformer used in electronic instruments and TV, radio and so on.
