　變壓器是變換交流電壓、交變電流和阻抗的器件，當初級線圈中通有交流電流時，鐵芯（或磁芯）中便產生交流磁通，使次級線圈中感應出電壓（或電流）。變壓器由鐵芯（或磁芯）和線圈組成，線圈有兩個或兩個以上的繞組，其中接電源的繞組叫初級線圈，其余的繞組叫次級線圈。隨著干式變壓器的推廣應用，其生產制造技術也獲得長足發展，可以預測，未來的干式變壓器將在如下幾方面獲得進一步發展：[2-3]　
⑴節能低噪：隨著新的低耗硅鋼片，箔式繞組結構，階梯鐵芯接縫，環境保護要求，噪聲研究的深入，以及計算機優化設計等新材料、新工藝、新技術的引入，將使未來的干式變壓器更加節能、更加寧靜。
⑵高可靠性：提高產品質量和可靠性，將是人們的不懈追求。
⑶環保特性認證：以歐洲標準HD464為基礎，開展干式變壓器的耐氣候(C0、C1、C2）、耐環境（E0、E1、E2）及耐火（F0、F1、F2）特性的研究與認證。
⑷大容量：從50～2500kVA配電變壓器為主的干式變壓器，向10000～20000kVA/35kV電力變壓器拓展，隨著城市用電負荷不斷增加，城網區域變電所越來越深入城市中心區、居民小區、大型廠礦等負荷中心，35kV大容量的小區中心供電電力變壓器將獲廣泛應用。⑸多功能組合：從單一變壓器向帶有風冷、保護外殼、溫度計算機接口、零序互感器、功率計量、封閉母線及側出線等多功能組合式變壓器發展。
⑹多領域發(fa)展：從以配電(dian)(dian)(dian)(dian)(dian)變(bian)壓(ya)(ya)(ya)(ya)器(qi)為主，向發(fa)電(dian)(dian)(dian)(dian)(dian)站廠(chang)用(yong)(yong)(yong)變(bian)壓(ya)(ya)(ya)(ya)器(qi)、勵磁變(bian)壓(ya)(ya)(ya)(ya)器(qi)、地鐵(tie)(tie)牽(qian)引整流變(bian)壓(ya)(ya)(ya)(ya)器(qi)、大電(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)爐(lu)變(bian)壓(ya)(ya)(ya)(ya)器(qi)、核電(dian)(dian)(dian)(dian)(dian)站、船用(yong)(yong)(yong)及(ji)采油平臺用(yong)(yong)(yong)等(deng)特種變(bian)壓(ya)(ya)(ya)(ya)器(qi)及(ji)多用(yong)(yong)(yong)途領域發(fa)展。其中，用(yong)(yong)(yong)于城市(shi)地鐵(tie)(tie)及(ji)軌道交(jiao)通的干式牽(qian)引變(bian)壓(ya)(ya)(ya)(ya)器(qi)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)有10、20和35kV三個等(deng)級，容量有800、2500和3300kVA，為減少諧(xie)波(bo)污染，從12脈波(bo)整流發(fa)展到24脈波(bo)整流；舉世矚目(mu)的長江三峽世界最大的840000kW發(fa)電(dian)(dian)(dian)(dian)(dian)機的勵磁變(bian)壓(ya)(ya)(ya)(ya)器(qi)，已由順(shun)特廠(chang)研制成功，并通過了國(guo)家驗收。
