Description

Technical Field

[0001] The utility model relates to the technical field of oil-immersed transformers, in particular to a rolling device for an oil channel curtain. Background Art

[0002] In recent years, my country's power construction has developed rapidly. At the same time, the speed of power grid construction has also advanced by leaps and bounds. The organization of power sources has also been constantly adjusted. The demand for transformers is increasing, and the requirements for ensuring the quality of transformers are becoming more stringent. The high and low voltage coils of distribution transformers are usually cylindrical. In order to dissipate heat, oil channels need to be set in the axial direction of the coils. The traditional oil channel adopts the structure of corrugated cardboard. Due to the low strength of corrugated cardboard, it is easy to flatten the corrugated cardboard when winding the coil, resulting in a small oil flow and affecting heat dissipation. If a large-sized corrugated cardboard is used, the size of the oil channel is increased, resulting in an increase in the coil diameter and an increase in cost. Now, curtain-type oil channels are usually used, that is, multiple stays are glued to two white cloths set in parallel to form a curtain-like appearance, which is wound into a cylinder, and the coil is wound on the cylinder.

[0003] During the production process of the oil channel curtain, the oil channel curtain needs to be rolled. At present, most of the production is done manually, but manual rolling will result in uneven rolling. Utility Model Content
