Abstract
The utility model relates to a prevent puncturing transformer coil, the coil is multi -layer cylinder formula coil, including high clamping ring and low clamping ring, should set up inside high clamping ring by low clamping ring, be equipped with the insulating layer between high clamping ring and the low clamping ring, be equipped with the supporting mechanism in this insulating layer, the supporting mechanism includes the stay that a plurality of axials side by side set up, and the stay is equal with coil height, be equipped with the multiunit on the stay with the enhancement strip of its partition on the height, the multiunit is strengthened the strip and is parallel circumference setting, there is insulating board in the stay outside still parcel, and insulating board and stay bond mutually, high clamping ring outward appearance parcel has the one deck to tighten the mechanism. The utility model discloses open the hole on the stay to strengthen fixedly through strengthening the strip, the steadiness of enhancement stay that can be further does not still influence the heat dissipation of coil, the pulling force that reduces the mechanism has been strengthened to a certain extent in the deflation area of slant cross arrangement for the more compact and non -deformable of coil.
Description
Technical field
The utility model relates to field transformer, refers to a kind of anti-breakdown transformer coil especially.
Background technology
Coil is the core component in transformer, plays a key effect in transformation work.Along with the market competition be growing more intense, the Cost Competition of Transformer product has become one of importance of its competition.Original circular coil is changed into elliptical line coil structures, has both met properties of product and technical requirement, effectively can reduce material again, cost-saving.But make the mechanical strength of coil decrease like this.After permanent, easily distortion, easily causes coil to puncture.Original coil uses insulating board to stick together from level to level, intermediary folds up one deck and uses insulating board to be compressed into corrugated cardboard, in transformer operation process, high-temperature baking and beat serious after corrugated insulating board cardboard can be made to be out of shape, cause radiating effect to be deteriorated, affect the transformer whole life-span.
Summary of the invention
The purpose of this utility model is just to provide a kind of anti-breakdown transformer coil, good heat dissipation effect, and the toughness adding coil makes it not easily breakdown, increases the useful life of coil.
Technical problem of the present utility model is solved mainly through following technical proposals:
A kind of anti-breakdown transformer coil, described coil is multi-layer cylindrical coil, comprise high pressure loop and low trim ring, this low trim ring is arranged at high pressure loop inside, insulating barrier is provided with between described high pressure loop and low trim ring, supporting mechanism is provided with in this insulating barrier, described supporting mechanism comprises some stays axially arranged arranged side by side, and stay is equal with coil height, described stay is provided with many groups in height by the stiffener of its decile, many groups stiffener is parallel circumference and arranges, also insulating board is enclosed with outside described stay, and insulating board and stay are bonding mutually, described high pressure loop appearance is enclosed with one deck and tightens mechanism.
Preferably, several the paper slips that described stay and stiffener cut into by insulating board also overlapping bondingly to form, the described stay paper slip number of plies is six layers, the stiffener paper slip number of plies is two-layer, multilayer paper slip aligns bonding mutually, described stay is in height provided with the through hole of many group horizontally sets, and through-hole aperture is suitable with stiffener size, described stiffener circumference setting and run through through hole.
Preferably, described deflation mechanism is netted, and the tightening belt that this deflation mechanism is arranged by some diagonal cross is worked out, and is also filled with the rhombus paper gasket suitable with mesh aperture size in the mesh in described deflation mechanism.
Preferably, described deflation mechanism is enclosed with the protective layer be made up of insulating point gummed paper in appearance.
The beneficial effects of the utility model are: the corrugated insulating board in the middle of insulating board is changed to stay by the utility model, stay cuts into strip by insulating board, and which floor paper slip is sticked together and is bonded on insulating board simultaneously, such change just can stop above defect afterwards, reach the benefit of life-span length, because stay is vertically arrange, just side is bonding with insulating board, there is certain insecure factor, so open hole on stay, and circumference is provided with the stiffener running through through hole, further can strengthen the steadiness of stay, also do not affect the heat radiation of coil, the tightening belt that diagonal cross is arranged strengthens the pulling force tightening mechanism to a certain extent, make coil more compact and not yielding, and increase its sealing effectiveness tightening paper fillers pad on the mesh in mechanism, and solve when through skin observation coil, outward appearance has uneven sense.
