　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多領域發展(zhan)：從以配電(dian)(dian)變(bian)(bian)壓(ya)(ya)(ya)器為主，向(xiang)發電(dian)(dian)站廠用(yong)(yong)變(bian)(bian)壓(ya)(ya)(ya)器、勵磁變(bian)(bian)壓(ya)(ya)(ya)器、地鐵牽引整(zheng)流(liu)(liu)變(bian)(bian)壓(ya)(ya)(ya)器、大電(dian)(dian)流(liu)(liu)電(dian)(dian)爐變(bian)(bian)壓(ya)(ya)(ya)器、核(he)電(dian)(dian)站、船用(yong)(yong)及(ji)采油平臺用(yong)(yong)等特(te)種變(bian)(bian)壓(ya)(ya)(ya)器及(ji)多用(yong)(yong)途領域發展(zhan)。其(qi)中，用(yong)(yong)于城市地鐵及(ji)軌道交通的(de)干式牽引變(bian)(bian)壓(ya)(ya)(ya)器，電(dian)(dian)壓(ya)(ya)(ya)有10、20和(he)35kV三個等級，容量有800、2500和(he)3300kVA，為減少諧波(bo)污(wu)染，從12脈波(bo)整(zheng)流(liu)(liu)發展(zhan)到24脈波(bo)整(zheng)流(liu)(liu)；舉世矚目的(de)長江三峽(xia)世界最(zui)大的(de)840000kW發電(dian)(dian)機(ji)的(de)勵磁變(bian)(bian)壓(ya)(ya)(ya)器，已由順特(te)廠研制成功，并通過了國家驗收(shou)。

VXDB11FA283PN變壓器又有其做試驗而用的，稱之為試驗變壓器，分別可以分為充氣式，油浸式，干式等試驗變壓器，是發電廠、供電局及科研單位等廣大用戶的用來做交流耐壓試驗的基本試驗設備，通過了國家質量監督局的標準，用于對各種電氣產品、電器元件、絕緣材料等進行規定電壓下的絕緣強度試驗。1．防止變壓器過載運行。如果長期過載運行，會引起線圈發熱，使絕緣逐漸老化，造成匣間短路、相間短路或對地短路及油的分解。2.防止變壓器鐵芯絕緣老化損壞。鐵芯絕緣老化或夾緊螺栓套管損壞，會使鐵芯產生很大的渦流，引起鐵芯長期發熱造成絕緣老化。3.防止檢修不慎破壞絕緣。變壓器檢修吊芯時，應注意保護線圈或絕緣套管，如果發現有擦破損傷，應及時處理。產品質量信譽保證,價格公道景東彝族自治縣S11變壓器
