变压器其交变电压的改变与初级线圈及其次级线圈的匝数成正比。
An electric transformer changes the alternating voltage applied to it in proportion to the Numbers of turns in its primary and secondary windings.
当处于焊接工况时，变压器次级采用全波整流方式，工作电压输出为36V；
The secondary side of the transformer uses the way of full-wave rectification and the output voltage is 36V, when it is in jointing.
当次级侧的分布式发电功率很小的时候，也有可能引起高电压，这是由于架空线路、次级线包和配电变压器上的电压降引起的。
This can even happen for a small DG located on the secondary because of the voltage drop along the service drop, the secondary wiring, and the distribution transformer.
