简介：摘要近年来，随着城镇化和工业化进程的逐步加快，社会经济呈现出繁荣的发展态势，各行各业对于电力能源的需求量和依赖程度有了很大提升，变压器作为电力系统的重要组成部分，在推动电力事业发展方面扮演着十分重要的角色。电力技术人员可以根据实际情况改变变压器的连接方式，而串联是一种非常普遍的连接方法，本文将简要概述串联变压器调压工作情况，并分析串联电路中实现调压需要的电力变压器的调压需求，希望为广大电力工作者提供有益借鉴。

简介：摘要：某学院用电情况：有四千多台空调，教室、教职办公室和学生、宿舍，学生差不多有两万三千人，四个人一台空调来计就有6千台空调。750W/匹粗略计算空调有5750台，乘以750W等于4312.5KW。增容前有十台630KVA变压器，后来加装的6台变压器、每台变压器1000KVA，加装的6台变压器兼顾了今年建的两个恒温泳池。为什么要用这么多变压器，原因一是每台变压器都是独立的，到用电高峰时电压就拖低，二是Dy接的变压器就算三相不平衡也不会Yy接的那样偏差大，在不调整三相负荷的情况下必然造成三相严重不平衡，受变压器容量限制用电高峰时就容易过载。本文以用电专户学校用电和公用变压器来论述，探讨学校节能设计和公用变压器节能降耗，本文涉及的学校数据和用电情况主要是用来分析，因没有这所学校具体的数据和真实的用电情况会有偏差。节能降耗困难在于，学校领导层不一定分辨出电工是否专业，不能单纯看考的什么资格证书的，专业熟练的电工还要有节能意识的学校领导，不是专业电工想做就能做的。公用变压器台区用电问题不比学校少，只不过学校比较集中好进行技改，所以先通过数据论述学校用电情况和解决方案，再探讨公变台区节能降耗就清晰。
