Abstract
The invention relates to mutual inductor production used self-embedded enclosed mass fixing structure improvement. The mutual inductor production used self-embedded enclosed mass fixing structure improvement is characterized in that the a split typed structure is adopted for the enclosed mass, one part is a rigid connection portion, the upper end portion of the connection portion is connected with a beam, the other part is an self-embedded locating portion made of epoxy resin materials, an arc locating portion is arranged at the lower end of the locating portion, the arc locating portion contacts with a poured mutual inductor body, a locating groove is reserved on the lower surface of the rigid connection portion, a locating pin is arranged on the self-embedded locating portion opposite to the locating groove, and the locating pin is inserted inside the locating groove. With the above technical scheme, after the pouring is finished, the self-embedded locating portion of the enclosed mass is left on and integrated with poured objects, and solidified opening and pouring dead heads are uniformly cut, products are saved from turning and secondarily material filling, the problem of scratch and damages of a first terminal of the mutual sensor is completely avoided, product quality is increased, working efficiency is greatly increased, and labor intensity of workers is reduced.
Description
Technical field
The invention belongs to instrument transformer manufacturing technology field, particularly relate 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, 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 resin mixture of filling of product, 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 present invention 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 object of the invention is to avoid upset after product moulding by casting is carried out to secondary feed supplement, thoroughly avoid because upset is to the scuffing of a terminal and damage.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is:
Instrument transformer is produced and to be 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 for to be made by epoxide resin material from ，Gai location division, buried location division, 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; The described portion that is rigidly connected is provided with detent below, and corresponding detent is provided with alignment pin from buried location division, and described alignment pin is inserted in detent.
Advantage and good effect that the present invention 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, that determines enclosed mass will stay on pour mass from buried location division, 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 invention;
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 invention, 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, describedly determine enclosed mass and 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 for to be provided with arc location division 1-20 from the lower end of 1-2，Gai location division, buried location division, described arc location division contacts with the instrument transformer device body 3 of being poured into a mould; The described portion that is rigidly connected is provided with detent 1-10 below, and 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, that determines enclosed mass will stay on pour mass from buried location division, 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 invention, not the present invention is done to any pro forma restriction, every foundation technical spirit of the present invention is to any simple modification made for any of the above embodiments, and equivalent variations and modification, all belong in the scope of technical solution of the present invention.
