变压器是现代电力系统必不可少的机器,构成变压器的材料主要有铁芯,线圈绕组及绝缘材料这三种材料。从工作原理来说,变压器的结构也比其它电气机器更为简单。因此,变压器性能的改进,几乎完全依靠所用材料的改良和更新。变压器线圈绕组,绝缘材料的更新,对变压器大容量化和高电压化,已经起到很大的作用,而变压器工作效率之所以能大幅度提高,主要是数十年来逐渐研制成能够降低铁损的铁芯用磁性材料的结果。
Transformer is an essential modern power system machines, the composition of the transformer material mainly iron core, coil winding and insulation materials of these three materials. From the working principle, the structure of the transformer is also simpler than other electrical machines. Therefore, the transformer performance improvement, almost entirely rely on the use of materials to improve and update. Transformer coil winding, insulation material updates, the transformer capacity and high voltage has played a significant role, and the reason why the working efficiency of the transformer can be greatly improved, mainly developed gradually over the past few years to reduce the iron loss The results of the core with magnetic material.
