The invention discloses a traction transformation device. The device comprises a plurality of cascaded sub-transformers and a plurality of bypass switches corresponding to the sub-transformers. The invention also discloses a traction transformation method. The method comprises the following steps: constructing the traction transformation device by using the multiple cascaded sub-transformers; opening or closing one or more sub-transformers in the traction transformation device according to actual requirement to realize the purpose of isolating the faulty sub-transformer/opening the standby sub-transformer. Compared with the prior art, the traction transformation device has the advantages of simple structure, stable operation and capabilities of greatly reducing the size and the weight, reducing the train design difficulty and greatly contributing to train speed raise.
