8K电力机车主变压器(型号为EFAT6844)是西欧50赫芝集团制造的。负责设计、试制的厂家是西门子公司下属的西德变压器联合公司斯图加特变压器厂,制造的厂家还有西柏林变压器厂(YOLTA厂)、巴黎变压器厂(阿尔斯通公司的圣·翁厂)、里昂变压器厂(MTE公司)及ACEC(比利时)。该变压器三位一体,除主变压器外,尚有平波电抗器,三次谐波电抗器及五次谐波电抗器它们装在一个油箱内。主变压器及平波电抗器卧放,冷却方式为强迫导向风冷却(ODAF)。较小的滤波电抗器为立放,冷却方式为强迫油循环风冷(OFAF)。这种三
8K electric locomotive main transformer (model EFAT6844) is made by Western Europe 50 Hertz Group. The manufacturer responsible for the design and trial production is the Stuttgart Transformer Factory of West Germany Transformer Joint Company under Siemens AG. The manufacturers also manufacture the West Berlin Transformer Factory (YOLTA), the Transformer Factory of Paris (St. Weng Factory of Alstom), the Lyon Transformer Factory (MTE) and ACEC (Belgium). The trinity of the transformer, in addition to the main transformer, there are flat wave reactor, third harmonic reactor and the fifth harmonic reactor installed in a tank. The main transformer and the smoothing reactor lie down. The cooling method is ODAF. Smaller filter reactors are erected and forced to cool by OFAC. This three
