Abstract
The utility model relates to an auxiliary junction box for a doubly-fed generator, and relates to the technical field of workpiece welding, the auxiliary junction box comprises a junction box body and a junction box cover plate, the junction box cover plate covers the junction box body, the junction box body and the junction box cover plate are both formed by bending a carbon steel plate, and the junction box cover plate covers the junction box body. A plurality of mounting holes are formed in the side wall and the lower bottom surface of the junction box body, the mounting holes are used for mounting cables, the left end and the right end of the inner bottom surface of the junction box body are respectively and fixedly connected with a heightening base plate, and a wire binding frame assembly and a guide rail assembly are fixedly mounted between the two heightening base plates. The junction box body and the junction box cover plate are manufactured through a carbon steel plate bending forming method, the size specification of the junction box can be adjusted according to needs, the use adaptability of the junction box is improved, meanwhile, molds do not need to be manufactured for junction boxes of different size specifications in the manufacturing process, the manufacturing cost of the junction box is effectively reduced, and the production efficiency of the junction box is improved. And the manufacturing period of the junction box is shortened.
