Abstract
The invention relates to a dry type transformer winding structure, which belongs to the technical field of power transformers. The dry type transformer winding structure is an improvement on the prior dry type transformer winding structure and is mainly characterized in that the surfaces of inner and outer windings are provided with waveform radiating layers, and by setting the waveform radiating layers, the structure effectively increases the radiating area; by calculation, the radiating area of the windings is increased by more than 1.5 times compared with the prior dry type transformer winding with the same power; and simultaneously, the structure reduces the whole structure of the inner and outer windings, reduces the using level of copper conductors, and effectively reduces the production cost. The dry type transformer winding structure has simple structure, obvious radiating effect, strong practicability and obvious economic benefit.
Description
Technical field
The present invention relates to a kind of dry type transformer winding structure, belong to the power transformer technical field.
Background technology
The winding of existing dry-type transformer from the iron core at center outwards is followed successively by in winding with outside winding, interior winding and outer winding all adopt the copper conductor coiling with insulating barrier, power and heat radiation requirement according to transformer under certain height, calculate the number of plies and the number of turns of inside and outside winding.The surfaces externally and internally of this inside and outside winding all is level and smooth, and area of dissipation is exactly the smooth exterior surface face, under the requirement of certain power, in order to satisfy the heat radiation requirement, often adopt to increase volume and relevant technical measures, improved raw-material consumption, thereby increased production cost.
Summary of the invention
The objective of the invention is at existing dry type transformer winding structure above shortcomings, be provided to meet and improve radiating efficiency under the power technology requirement, thereby can dwindle the overall structure of winding, reduce raw material, especially reduce copper conductor use amount, a kind of dry type transformer winding structure that reduces production costs.
The objective of the invention is to be achieved through the following technical solutions, a kind of dry type transformer winding structure comprises iron core, and winding and outer winding in iron core is followed successively by outward is characterized in that the surface of described interior winding and outer winding is provided with corrugated heat dissipating layer.
The surface of interior winding and outer winding is that outer surface is provided with corrugated heat dissipating layer.
The surface of interior winding and outer winding is that inside and outside surface all is provided with corrugated heat dissipating layer.
Heat dissipating layer adopts the epoxy resin layer.
The present invention is the improvement to existing dry type transformer winding structure, by surface corrugated heat dissipating layer is set, has increased area of dissipation, as calculated at inside and outside winding, the area of dissipation of winding has increased more than 1.5 times with the existing dry-type transformer winding of power relatively, simultaneously, dwindle the overall structure of inside and outside winding, reduced the use amount of copper conductor, effectively reduce production cost, the present invention is simple in structure, and radiating effect is obvious, has very strong practicality and remarkable economic efficiency.
