变压器主要分类
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.
