摘要
在我国,大型工业企业通常是分期建设的,相应地,企业的供配电网络也是分期投产来满足不同生产阶段的企业用电需求。配电变压器作为供配电网络中的主要设备,数目众多且型号各异,耗能水平不一,新旧并存,许多早期投产的变压器已经成为待淘汰的高耗能落后变压器。文章分析了配电变压器的发展历史及大型工业企业的变压器现状,针对企业配电变压器的淘汰更新中的具体问题进行了讨论,对工业企业的变压器淘汰更新具有参考意义。
In China, large-scale industrial enterprises as well as its power supply and distribution networks usually are constructed by stages in several years. For this reason, there are many types of transformers with different energy consumption, and some of them need to be renovated combining the situation of energy and environmental protection at present. In this paper, discussion is done for the replacement of transforms based on the introduction and analysis of the development of transformer and its status in big industrial enterprises are introduced.
