Abstract
The utility model discloses a universal winding gear for a three-dimensional wound core of a dry type transformer. The universal winding gear is mainly characterized in that the universal winding gear for the three-dimensional wound core of the conventional dry type transformer is improved; and the universal winding gear comprises a retainer ring, a track ring and a gear, wherein the gear is fixed on a gear baffle plate, and the inner diameter and outer diameter of the gear baffle plate are respectively matched with the diameter of an iron core and the center distance of the iron core. The inner diameter of the universal winding gear is not influenced by the diameter of the iron core, and the outer diameter of the universal winding gear is not limited by the center distance, so that the diversification of the use of the gear is achieved, the amount of the winding gears is reduced, the production cost is reduced, and the working efficiency is improved.
Description
Technical field
The utility model relates to gear, is specifically related to the general coiling gear of a kind of dry-type transformer three dimensional wound core.
Background technology
The coiling of three-dimensional wound core dry type transformer (SCB-RL-) coil utilizes gear to finish.Needed device is retainer ring, orbit ring and gear, and referring to Fig. 1, gear and orbit ring all are that two semi-rings are combined into, and different from oil immersed type solid transformer coil winding is that two gear structures are different, is divided into cogging and lower gear.Referring to the assembling of Fig. 2 gear be: retainer ring is fixed on the iron core column, orbit ring is connected with retainer ring with bolt, again the gear of two semi-rings is combined into integral body, embed on the orbit ring, load onto winding former, with foil coiling low-voltage coil, low-voltage coil is loaded onto the casting internal mold with bolt afterwards around complete, coiling high-tension coil on the casting internal mold is loaded onto at last external mold and is cast.
In technique shown in Figure 2, gear interior through being to change according to diameter of phi unshakable in one's determination, the outer warp of gear will be determined according to the centre-to-centre spacing Mo of iron core frame.Because the specification of transformer does not wait, and also is subject to full copper, half bronze medal, so the impact of the factors such as full aluminium, GB principal-employment, GB minus tolerance, southern network mark and province-norm is of a great variety.The core-diameter Φ of each and centre-to-centre spacing Mo are different, so the gear set specifications that needs is too many, have greatly increased production cost, are difficult to again guarantee client's delivery date.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gear size and fixes, and the gear internal diameter is not subjected to the impact of core-diameter, and the outside diameter of gear is not subjected to the restriction of iron core frame centre-to-centre spacing and the general coiling gear of the diversified dry-type transformer three dimensional wound core of gear purposes.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that the general coiling gear of dry-type transformer three dimensional wound core of design comprises retainer ring, orbit ring and gear, is described gear fixed on gear shelves (gear?) on the plate, gear shelves (gear?) internal diameter of plate and external diameter respectively with iron core the centre-to-centre spacing of diameter, iron core suitable.
For the sealing of the inner membrance that guarantees to cast, cog at the gear plate washer and to establish by the fixing screw rod of screw and gear plate washer with the opposite of the stationary plane of gear plate washer.
For the sealing of the adventitia that guarantees to cast, establish a flange that is bolted on the gear plate washer in the bottom of the external mold of casting on the gear.
The utility model adopts the designed general coiling gear of this dry-type transformer three dimensional wound core of technique scheme, the gear that utilizes by the coiling to existing three-dimensional wound core dry type transformer coil is improved, gear is fixed on the gear plate washer, the gear internal diameter is not subjected to the impact of core-diameter, the outside diameter of gear is the restriction of acceptor center distance not, makes the gear purposes reach variation, has reduced coiling gear quantity, reduce production cost, improved operating efficiency.

Embodiment
Specify below in conjunction with the structure of accompanying drawing to the general coiling gear of the utility model dry-type transformer three dimensional wound core.
Referring to Fig. 1, Fig. 2, before improving, the general coiling gear of the utility model dry-type transformer three dimensional wound core comprises retainer ring 1, orbit ring 2, gear 3, gear 3 and orbit ring 2 all are that two semi-rings are combined into, retainer ring 1 is fixed on the stem of iron core 9 during assembling, orbit ring 2 usefulness bolts are connected with retainer ring 1, again the gear of two semi-rings is combined into integral body, embed on the orbit ring 2, load onto winding former 11, with foil coiling low-voltage coil 10, low-voltage coil 10 is loaded onto casting internal mold 7 with bolt afterwards around complete, coiling high-tension coil 6 on casting internal mold 7 is loaded onto at last external mold 5 and is cast.
Referring to Fig. 3, the structure of the general coiling gear of the utility model dry-type transformer three dimensional wound core comprises retainer ring 1, orbit ring 2 and gear 3, wherein, gear 3 is fixed on the gear plate washer 4, the material of gear plate washer 4 is Q235, and it need not fine finishining and heat treatment, and the internal diameter of gear plate washer 4 and external diameter are suitable with the centre-to-centre spacing of the diameter of iron core 9, iron core 9 respectively, the internal diameter that is gear plate washer 4 is determined that by unshakable in one's determination 9 diameter the external diameter of gear plate washer 4 changes with unshakable in one's determination 9 centre-to-centre spacing.Like this, the same gear can be adapted to the coiling of plurality of specifications transformer coil.Sealing for the inner membrance 7 that guarantees to cast, cog at gear plate washer 4 and 3 to establish the screw rod 8 of fixing by screw and gear plate washer 4 with the opposite of the stationary plane of gear plate washer 4, the length of screw rod 8 is approximately greater than casting inner membrance 7 height, be screw rod 8 one end threadings, it is stretched into from the other end be tightened onto on the gear plate washer 4, thereby press seal packing ring (not shown) reaches the purpose of sealing.For the sealing of the adventitia 5 that guarantees to cast on the gear 3, establish a flange (not shown) that is bolted on the gear plate washer 4 in the bottom of external mold 5, press seal rubber cushion (not shown) reaches sealing.
