Abstract
The utility model provides a transformer rectangular coil, consisting of two waist-shaped coils symmetrically integrated. On the core of each coil is arranged a square insulated framework. Around the insulated frameworks are wound low voltage coils and on the low voltage coils are wound high voltage coils. Between the high and low voltage coils are arranged main empty paths. Between layers of the high-voltage coils are arranged double-sided dotted glue paper with flanging at two boundaries. All the heat discharge oil ducts on the coils are arranged outside the core window and no heat discharge oil duct is arranged at the exterior round corner of the coils. The utility model is characterized by the advantage that a rectangular transformer coil is provided to improve the enwinding efficiency, reduce the producing cost and improve the utilization ratio of the round oil tank.
Description
Affiliated technical field
The utility model relates to a kind of transformer rectangular coil, belongs to the transformer equipment technical field.
Background technology
At present, the transformer coil that the 6-10KV that tradition is used is following mostly is a cylinder integral type coil, and the coiling of lead continuous multilayer separates by one deck insulating material between every layer line circle, and end winding is provided with insulating end ring.This coil has shortcomings such as manufacture craft is many, cost of manufacture is high, the easy obstruction of interlayer oil duct.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned technology, and a kind of transformer rectangular coil that can improve coiling efficient, saving cost of manufacture, improve circular fuel tank utilance is provided.
The technical solution of the utility model is: a kind of transformer rectangular coil, the coil that it has two waist shapes permutation and combination in opposite directions constitutes together.Every coil all iron core is provided with square insulation framework, first coiling low-voltage coil on insulation framework, coiling high-tension coil on low-voltage coil again.Be provided with main empty path between the high and low pressure coil.The layer insulation of high-tension coil adopts both sides to have two-sided some gummed paper of flanging.Both sides earlier constitute flanging to the limit of the same width of two edge breaks to middle flanging during to certain width again during two-sided some gummed paper flanging, and this flanging is coil insulation end circle.Its flanging width should be identical with the insulating end ring width of design of transformer.As the flanging thickness low LCL can be between flanging cushioning liner paperboard strip with the thickness of thickening flanging.All heat radiation oil ducts on the coil all are arranged on the outside of core window, and oil duct is not placed at the bull nose place of coil, make two whole coil near cylindrical after the coil combination like this, and this coil shape has improved the space availability ratio of cylindrical oil tank.
The utility model has the advantages that provides a kind of transformer rectangular coil that can improve coiling efficient, saving cost of manufacture, improve circular fuel tank utilance.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of two-sided some gummed paper both sides of the utility model flanging.
Among the figure: 1, high-tension coil, 2, low-voltage coil, 3, main empty path, 4, insulation framework, 5, heat radiation oil duct, 6, iron core, 7, coil, 8, layer insulation, 9, flanging, 10, paperboard strip.
Embodiment
A kind of transformer rectangular coil, as Fig. 1-shown in Figure 2: the coil 7 that it has two waist shapes permutation and combination in opposite directions constitutes together.Every coil 7 all is that iron core 6 is provided with square insulation framework 4, first coiling low-voltage coil 2 on insulation framework 4, coiling high-tension coil 1 on low-voltage coil 2 again.Be provided with main empty path 3 between the high and low pressure coil.The layer insulation 8 of high-tension coil 1 adopts both sides to have two-sided some gummed paper of flanging 9.Both sides earlier constitute flanging 9 to the limit of the same width of two edge breaks to middle flanging during to certain width again during two-sided some gummed paper flanging, and this flanging 9 is coil insulation end circle, does not so just need to have added insulating end ring in addition.Its flanging width should be identical with the insulating end ring width of design of transformer.As flanging 9 thickness low LCLs can be between flanging cushioning liner paperboard strip 10 with the thickness of thickening flanging 9.This structure makes coil can improve coiling efficient, saves cost of manufacture.All heat radiation oil ducts 5 on the coil 7 all are arranged on the outside of iron core 6 windows, heat radiation oil duct is not placed at the bull nose place of coil 7, make the whole coil near cylindrical after two coils 7 make up like this, this coil shape has improved the space availability ratio of cylindrical oil tank.
