Abstract
The utility model discloses a new construction coil without internal stay which is suitable for a pancake transformer. The utility model is a coil without internal stay. The coil is directly wound on a paperboard cylinder or a bakelite cylinder, and a crepe paper is padded on the paperboard cylinder or the bakelite cylinder; when the coil is wound for a certain number of turns, a paperboard strip whose interstice is adhered with a space block of small oil clearance is spooled in the middle of the coil, a millboard strip is penetrated into a void; an intersegmental space block is penetrated into the millboard strip, and the intersegmental space block is fixed. After the coil is wound up, an outer stay is fixed. The utility model has the advantages of reduction of insulation distance, alleviation of dead weight and primary materials saving.
Description
The utility model is a kind of new construction coil that does not have interior stay, is applicable to the transformer of disc coil.
At present, traditional disc coil structure has stay in inner radius, with the fixing cushion block that constitutes intersegmental oil duct.This structure has a vertical oil duct at the internal diameter of coil.The high-tension coil of high voltage transformer, in the ordinary course of things, the maximum field strength district appears at the inner radius of coil.Owing to technologic reason, vertical oil duct of inner radius can not be done very for a short time, and this has just limited the raising of field intensity allowable in the oil.Therefore, high-tension transformer will have bigger insulation distance.Make winding volume, deadweight increases, the waste raw material.
The purpose of this utility model provides a kind of coil that does not have interior stay, coil can be directly on the fiber core that is lined with crimped paper, or on the bakelite cylinder, the field intensity allowable of paper compares innage, under equal voltage, can make the transformer device structure compactness thereby can dwindle insulation distance about 15%, alleviate the transformer deadweight, save material.
The utility model is realized with following technical scheme: first kind of scheme be earlier with coil directly on fiber core that is lined with crimped paper or bakelite cylinder, when around the time to a fixing turn, the paperboard strip spooling that at interval is stained with the small oil gap cushion block in the middle of coil, is so just produced space at interval.Penetrate in the space with a ground paper lath again, the holddown groove with interior stay binding that intersegmental cushion block is opened by former top changes in the middle part of intersegmental cushion block opens a square hole, another top is with equally having dovetail groove originally, the intersegmental cushion block that has square hole is penetrated the ground paper lath, just intersegmental cushion block can be fixed.Continue coiling again, coil penetrates outer stay in the dovetail groove of intersegmental cushion block, fixedly outer stay after finishing again.
Second kind of scheme be earlier with coil directly on fiber core that is lined with crimped paper or bakelite cylinder, when around the time to a fixing turn, in the middle of coil, the oil clearance cushion block shape that is bonded on the first circle coil place paperboard strip is with the paperboard strip that is stained with the oil clearance cushion block
Shape.The shape that the intermediate coil place is bonded at the oil clearance cushion block on the paperboard strip is
Shape.Penetrate on the oil clearance cushion block the intersegmental cushion block that has square hole fixing.Continue coiling again, coil after intact, fixing outer stay again.
The third technical scheme is: earlier with coil directly on the fiber core that is lined with crimped paper or on the bakelite cylinder, when around the time to a fixing turn, to be stained with the paperboard strip of oil clearance cushion block in the middle of coil at interval, produce space at interval, cushion block is placed on the gap between the plurality of sections of square hole with having, the intersegmental cushion block that will have boss is again put together with the intersegmental cushion block that has square hole, and after penetrating boss in the square hole, continue to pierce in the space that the paperboard strip that is stained with the oil clearance cushion block and coil form, with cushion block between canned paragraph, continue coiling again, coil after intact, fixing outer stay again.
The utility model is owing to cancelled interior stay, and coil can under equal voltage, can dwindle insulation distance, thereby make the compacter weight that alleviates transformer of transformer device structure directly on fiber core or on the bakelite cylinder, saves raw material.
Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1～11st, specific embodiment of the utility model.Embodiment 1, earlier that coil 3 is direct on fiber core that is lined with crimped paper 2 or bakelite cylinder 1, when around the time to a fixing turn, to be stained with paperboard strip 4 spoolings of oil clearance cushion block 5 at interval in the middle of coil 3, like this because the support of oil clearance cushion block 5, just produced certain space, a ground paper lath 6 has been penetrated in the space again, the intersegmental cushion block 7 that the middle part is had square hole penetrates in the ground paper lath 6 fixing.And then continuing coiling, coil 3 penetrates outer stay 8 in the dovetail groove of intersegmental cushion block 7 fixing after intact again.
The utility model is compared with former disk-type winding with inner bracing strip: because the utility model has been cancelled inner bracing strip, line segment can be directly on the fiber core that is lined with crimped paper, the field intensity allowable of paper compares innage, under equal voltage, can dwindle insulation distance, thereby make transformer device structure compacter, alleviate the deadweight of transformer, save raw material, prolong the service life of transformer.
Claims (2)
1, stay transformer coil in a kind of nothing, it is characterized in that earlier that coil 3 is direct on fiber core that is lined with crimped paper 2 or bakelite cylinder 1, when around a fixing turn, to be stained with paperboard strip 4 spoolings of oil clearance cushion block 5 at interval in the middle of coil 3, ground paper lath 6 is penetrated the oil clearance cushion block to be supported in the space that produces, the intersegmental cushion block 7 that the middle part is had square hole penetrates in the ground paper lath 6 fixing, coil 3 is after finishing, again outer stay 8 is penetrated in the dovetail groove of intersegmental cushion block 7 fixingly, also can adopt oil clearance cushion block 5 shapes that are positioned on the first circle coil place paperboard strip to be
