变压器按用途分：
The transformer is divided into 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.
