Abstract
The utility model relates to a to transformer structure, in particular to a low voltage coil of dry type transformer. A complete sheet of clutch gold with thin thickness is used as a copper conductor in the low voltage coil of dry type transformer. The width of the clutch gold is almost the same as the height of the coil, and the clutch gold is wound to form a cylindrical multilayer structure. The beginning terminal and the end of the clutch gold are welded on the head of the coil respectively. Insulating layers are wound between each clutch gold simultaneously, and insulating supporting shoes are arranged at intervals every several layers. The utility model can eliminate the helix angle on the end of the coil, and has high ability against outburst short circuit. Furthermore, the utility model is easy to manufacture.
Description
Technical field
The utility model relates to transformer device structure, specifically is a kind of low-voltage coil of dry type transformer.
Background technology
The low-voltage coil of present dry-type transformer adopts be multiple conducting wires and around helical winding, the end winding of this structure exists bigger helical angle, can produce bigger leakage field in the end during transformer operation, the anti-sudden short circuit of transformer is indifferent.The technique for coiling complexity of this exterior loop, production efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of helical angle that can eliminate end winding is provided, and has higher anti-sudden short circuit ability, and the low-voltage coil of dry type transformer that is easy to make.
Low-voltage coil of dry type transformer of the present utility model with whole Copper Foil of thinner thickness as copper conductor, the width and the coil height of Copper Foil are suitable, Copper Foil is reeled and is formed cylindric sandwich construction, the top of Copper Foil and end are welded on the winding protruding head respectively, be wound with insulating barrier between each layer Copper Foil simultaneously, and be arranged at intervals with dielectric support block every the several layers Copper Foil.
Therefore the utility model can together roll with layer insulation on roll-leaf equipment fast owing to replace traditional lead as copper conductor with whole Copper Foil, and each layer is a circle, has simplified the technique for coiling of coil, has improved production efficiency; This structure has been eliminated the helical angle of end winding in addition, has improved the anti-sudden short circuit ability of transformer.
