transformer size

In recent years, the level and capacity of power transformer improve continuously, with the increase in domestic demand for electricity and the grid size. However, at the same time transformer failure rate and repair time are also increasing.

近些年来，随着国内电力需求和电网规模的扩大，电力变压器等级和容量不断提高，变压器故障率和修复时间也随之不断增大。

The bacteria Planococcus sp-, Pseudomonas sp-and Xanthomonas sp' obtained from the dielectric oil of a scrapped large-size transformer were studied on their states and metablism.

从报废的大型变压器介质油中分离得到动性球菌、假单胞菌、黄单胞菌等细菌，并对其形态和代谢进行研究。

The optimized transformer of EPX ( EPO) has less several dB in THD than the transformer of EP when they have the same package size.

选择优化后的EPX（EPO）型磁芯制作的变压器比同等封装尺寸下EP型变压器的谐波失真要低几个dB，或在变压器谐波失真未有太大改变的情况下缩小了变压器的封装尺寸；
