Embodiment 1)
[0021] See figure 1 , The vertical closed iron yoke end ring used in the transformer of this embodiment is mainly composed of an outer closed cylinder 1 , an inner cylinder 2 and a glue layer 3 .
[0022] The outer closed tube 1 is a tube-shaped cardboard structure with a circular cross-section.
[0023] The inner layer tube 2 is a structural member formed by bending and butting of cardboard and has a circular cross-section. The inner layer tube 2 is provided with a closed docking port 2-1. The ends are butted; the inner tube 2 is provided with more than 2 layers in the outer closed tube 1 from the outside to the inside.
[0024] The glue layer 3 is arranged between the outer end face of the inner layer cylinder 2 located at the outermost side, the inner end face of the outer layer closed-mouth cylinder 1 and the outer end faces and inner end faces of the two adjacent inner layer cylinders 2, and the outermost inner layer cylinder is connected. 2. It is bonded to the outer c...
