Low power factor, harmonic and negative sequence current are the negative power in the power system. They are usually compensated, filtered and adjusted by parallel components. A more economical approach is to use some loads to compensate for other loads and to load some of the load with some load, so a generic transformer with more outgoing lines will be the industry's lead. The use of epoxy resin casting dry-type transformer technology, but the more outgoing than secondary winding mould structure and high technical difficulty, winding pouring completed complex, easy to burst power, the invention integrally poured winding is divided into several modules, each module has simple structure, easy to mold and products of heat, can be neutralized the negative power module winding general transformer design method and open. The invention has the advantages of clear principle, simple structure, high reliability and low cost, and has larger radiating area than the integral pouring transformer, so that the mass production can be realized conveniently. The invention can adjust the load state of the transformer itself and the bus bar statically and dynamically, and can provide adjustment resources to the upper level system according to the requirements of the power supply department.
