Abstract
The utility model relates to a structural improvement of a self-embedding ladle fixing block for production of a mutual inductor. The structural improvement of the self-embedding ladle fixing block for the production of the mutual inductor is characterized in that the ladle fixing block adopts a splitting structure comprising a rigid connection part and a self-embedding positioning part; the upper end part of the connection part is connected with a crossbeam; the self-embedding positioning part is made of an epoxy resin material; the lower end of the positioning part is provided with an arc positioning part contacted with the body of a poured mutual inductor; a positioning groove is arranged under the rigid connection part; a positioning pin is arranged on the self-embedding positioning part by corresponding to the positioning groove; the positioning pin is inserted in the positioning groove. By adopting the technical scheme, after the pouring is finished, the self-embedding positioning part of the ladle fixing block is remained on the pouring part and integrated with the pouring part, after a port to be cured and a pouring dead head are cut off together, product overturning and secondary material compensating are not needed by adopting the structure, the problem that a primary terminal of the mutual inductor is scratched and damaged is solved, the product quality is improved, the work efficiency is greatly improved and the labor intensity of a worker is reduced.
Description
Technical field
The utility model belongs to instrument transformer manufacturing technology field, particularly relates to a kind of instrument transformer production architecture advances of determining enclosed mass from buried.
Background technology
Resin-cast Insulated Current Transformers is in moulding by casting process, the device body 3 of its product, by two of casting mold, determining enclosed mass locates, refer to Fig. 2, and with the fastening lifting of two high-intensity bull ladle bands 4, it is the relatively more conventional a kind of technology of most of instrument transformer producer that this use is determined the bull ladle method that enclosed mass locates.
But, prior art existent defect and deficiency, when after moulding by casting cure and demold, two positions of determining enclosed mass, on its cast product, leave the pit of two locating piece shapes, need to be by the bottom-up product resin mixture of filling, now primary connection terminal surface in product top extremely easily causes scuffing, to the product with anti-electric wall, also can cause distortion simultaneously, affect product appearance quality, and processing is more difficult in repair process, thereby cause the quality of product and production efficiency all to decline to some extent.
Summary of the invention
The utility model provides a kind of instrument transformer production architecture advances of determining enclosed mass from buried for solving the technical problem existing in known technology.
The purpose of this utility model is to avoid upset after product moulding by casting is carried out to secondary feed supplement, thoroughly avoids because of scuffing and the damage of upset to a terminal.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
Instrument transformer is produced and is used an architecture advances of determine enclosed mass from buried, comprises and determines enclosed mass, it is characterized in that: describedly determine enclosed mass employing Split type structure, a part is the portion of being rigidly connected, and the upper end of this connecting portion is connected with crossbeam; Another part is from buried location division, and this location division is made by epoxide resin material, and the lower end of location division is provided with arc location division, and described arc location division contacts with the instrument transformer device body of being poured into a mould; Below the described portion that is rigidly connected, be provided with detent, corresponding detent is provided with alignment pin from buried location division, and described alignment pin is inserted in detent.
Advantage and the good effect that the utlity model has are: owing to determining enclosed mass to two on casting mold, improve, be about to it and transform split-type structural as, comprise the portion that is rigidly connected that is connected with upending frame and from buried location division, the material wherein adopting from buried location division is epoxy resin, after casting complete, determine staying on pour mass from buried location division of enclosed mass, and form one with pour mass, waiting to solidify mouth unifies and cuts with cast rising head, thereby complete cast operation, adopt this structure not need product upset and secondary feed supplement, the scuffing of a terminal of instrument transformer and the problem of damage have thoroughly been avoided, improved the quality of product, and compared to the prior art operating efficiency has had and has increased substantially, workman's labour intensity declines to some extent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is prior art structural representation.
In figure: 1, determine enclosed mass; 1-1, portion is rigidly connected; 1-10, detent; 1-2, from buried location division; 1-20, arc location division; 1-21, alignment pin; 2, crossbeam; 3, device body; 4, bull ladle band; 5, a terminal.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of instrument transformer is produced and is used the architecture advances of determining enclosed mass from buried, comprises and determines enclosed mass 1, described determine enclosed mass adopt Split type structure, a part is the 1-1 of portion that is rigidly connected, and the portion that is rigidly connected is made by No. 45 steel, and the upper end of this connecting portion is connected with crossbeam 2; Another part is from buried location division 1-2, and the lower end of this location division is provided with arc location division 1-20, and described arc location division contacts with the instrument transformer device body 3 of being poured into a mould; Below the described portion that is rigidly connected, be provided with detent 1-10, corresponding detent is provided with alignment pin 1-21 from buried location division, and described alignment pin is inserted in detent.Said structure is after casting complete, determine staying on pour mass from buried location division of enclosed mass, and form one with pour mass, wait to solidify mouth and unify and cut with cast rising head, thereby complete cast operation, adopt this structure not need product upset and secondary feed supplement, the scuffing of a terminal 5 of instrument transformer and the problem of damage have thoroughly been avoided, improved the quality of product, and compared to the prior art operating efficiency had and increased substantially, workman's labour intensity declines to some extent.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
