Combined transformer

The utility model provides a combined transformer which comprises a plurality of sub-components, the sub-components are combined to form a transformer body, each sub-component comprises a first side plate and a second side plate, an iron core is fixedly connected between the first side plate and the second side plate, a coil is wound on the peripheral side of the iron core, the side face of the second side plate is fixedly connected with a plurality of combined buckles, and the combined buckles are fixedly connected with the first side plate and the second side plate. And the combined buckle on the side surface of one sub-component corresponds to the first side plate of the other sub-component. According to the transformer, the transformer body is divided into a plurality of sub-components, the combined buckles are installed on the side faces of the second side plates, the sub-components can be combined, so that transformers of different specifications can be manufactured according to the number of the sub-co
