英语翻译
变压器是利用电磁感应的原理来改变交流电压的装置,主要构件是初级线圈、次级线圈和铁心（磁芯）.在电器设备和无线电路中,常用作升降电压、匹配阻抗.安全隔离等.它的功能主要有：电压变换；电流变换,阻抗变换；隔离；稳压（磁饱和变压器）;自耦变压器；高压变压器（干式和油浸式）等

Answer 1

Transformer is to use the principle of electromagnetic induction to change the AC voltage of the device,the main component is the primary coil,secondary coil and core (core).In the electrical equipment and radio roads that are commonly used for lifting voltage and impedance matching.Security isolation.Its features are:voltage transform; current transformation,impedance transformation; isolation; Regulators (magnetic saturation transformer); auto-transformer; high-voltage transformer (dry type and oil-immersed),etc.
