我国首台拥有自主知识产权的220k V/56.5MVA卷铁心牵引变压器日前通过了国家变压器质检监督检验中心的短路试验和全套型式试验,标志着世界上第一台大型卷铁心节能牵引变压器在我国研制成功。相比目前被广泛使用的叠片式变压器,卷铁心牵引变压器能够降低空载能耗40%以上,即将被安装到中南通道王家庄牵引变电所做示范应用。卷铁心牵引变压器的研制成功是我国产学研用结合的典型案例。该项目由中国铁路总公司立项支持,常州太平洋
China’s first 220k V / 56.5MVA wound core traction transformer with independent intellectual property rights passed the short circuit test and a full set of type tests conducted by the State Transformer Quality Supervision, Inspection and Supervision Center marking the world’s first large-scale wound core energy-saving traction transformer in China Developed successfully. Compared to the currently widely used laminated transformers, the wound core traction transformer can reduce the no-load energy consumption by more than 40% and is about to be installed in the pilot application of Wangzhuang traction substation of Zhongnan channel. The successful development of the wound core traction transformer is a typical case of the combination of production, study and research in our country.
