Abstract
The invention discloses a continuous high-voltage coil for a resin-cast dry-type transformer. The coil comprises winding conductors and is characterized in that a coil wound with the winding conductors comprises a group of cakes continuously wound according to positive and negative cake type structures; the cakes are continuously arranged side by side; and insulating layers are arranged between adjacent cakes. The continuous coil wound by the insulated flat conductors with high electric strength has the following beneficial effects that the conductor filling rate of the coil can be increased; and the transformer loss and cost can be reduced.
Description
Technical field
The present invention relates to a kind of transformer coil, specifically a kind of new-type resin casting dry-type transformer high-tension coil.
Background technology
At present, conventional resin casting dry-type transformer coil is the coiling of subsection cylindrical formula, like Fig. 1, and among the figure, the 51st, lead, the 52nd, section fills 53 for the resin-cast material between every section.Owing to must leave the intersegmental distance of enough surpluses, winding volume subtracts greatly, big, the whole cost height of loss so cause during the coil winding of this structure.
Summary of the invention
In order to overcome the problem that existing technology exists; The purpose of this invention is to provide a kind of resin casting dry-type transformer continuous high pressure coil; This coil can increase the conductor filled rate of coil for adopting the continuous winding of high electric strength insulation flat conductor coiling, reduces transformer loss and cost.
The objective of the invention is to realize through following technical scheme:
A kind of resin casting dry-type transformer continuous high pressure coil; Comprise the coiling lead; It is characterized in that: the coil of said coiling lead coiling comprises one group of cake piece that carries out the continous way coiling according to positive and negative cake formula structure, and one group of cake piece is provided with side by side continuously, is provided with insulating barrier at adjacent cake interblock.
Among the present invention, said coiling lead is high electric strength insulation flat conductor.One group of cake piece is close to setting side by side continuously.
Compared with prior art, coil-conductor of the present invention is that many cakes continous way is arranged, and has made full use of the high electric strength of conductor insulation; Increased the conductor filled rate of coil; The winding volume of coiling reduces, and has not only reduced production cost, and transformer loss is reduced.The present invention is applicable in the resin casting dry-type transformer.
Description of drawings
Fig. 1 is that existing resin casting dry-type transformer high-tension coil is arranged sketch map for the subsection cylindrical formula winding wire that adopts.
Fig. 2 is a high-tension coil continuous winding arrangements of conductors sketch map of the present invention.
Embodiment
A kind of resin casting dry-type transformer continuous high pressure coil of the present invention is seen Fig. 2, and numeral 1 to 30 is a number of turn code name among the figure, is which circle.This coil comprises coiling lead 41, and coiling lead 41 is high electric strength insulation flat conductor.The coil of coiling lead 41 coilings comprises that one group of 43, one groups of cake piece 43 of cake piece that carry out the continous way coiling according to positive and negative cake formula structure is close to setting side by side continuously, is provided with insulating barrier 42 43 of adjacent cake pieces.
During coiling, lead 41 is carried out the continous way coiling according to positive and negative cake formula structure,, only add one deck thin dielectric layer 42 and get final product, be close between each cake, until all number of turn coilings are finished because 43 voltages of cake piece are lower.The existing high-tension coil of coiling after image equally carries out moulding by casting.
Coil-conductor of the present invention is that many cakes continous way is arranged, and has made full use of the high electric strength of conductor insulation, has increased the conductor filled rate of coil, and the winding volume of coiling reduces, and has not only reduced production cost, and transformer loss is reduced.
