Abstract
A new hull for pouring current transformer, comprises the procapsid and back casing that snap together, is wherein provided with the core cylinder for location current mutual inductor coil in procapsid, and the outside of core barrel body is provided with location fin; Back casing is provided with core bore, and core bore is provided with detent, and location fin matches with detent and back casing is positioned on procapsid.Adopt front and rear housings of the present utility model, the method of tradition cast is instead of when making instrument transformer, get rid of casting mold and heated oven, can production environment be improved, reduce labour intensity, enhance productivity, and be convenient to realize automated production, and the production cost of product does not significantly improve, also product appearance quality have also been obtained raising simultaneously, has very large social benefit.
Description
Technical field
The utility model belongs to current transformer technical field, specifically relates to a kind of new hull of pouring current transformer.
Background technology
Current pouring current transformer makes and all adopts metal die, coil is fixed in die cavity, and coil is positioned, embedding is carried out again with unsaturated-resin compound, put into high temperature oven rapid curing, form product after the demoulding, portioned product have cracking, turn white, the shortcoming such as burr, bias.During batch production, a large amount of casting molds can be needed, run high temperature oven for a long time, also comparatively large to the consumption of electric energy, also shorten the mold use life-span.A large amount of unwanted volatiles during hot setting in unsaturated-resin compound can spill in air, and to environment, operating personnel work under being in hot environment for a long time, are all unfavorable for that it is physically and mentally healthy.A small amount of gas in unsaturated-resin compound, can form pore on the surface of product pour mass after hardening, affect the presentation quality of product and the reliability of insulation.The casting mold that casting mold needs frequent carrying heavy in the process of the die-filling and demoulding, mixing unsaturated-resin needs to stir for a long time with during curing agent, and therefore comparatively greatly, production efficiency is lower for operating personnel's physical demands.
Summary of the invention
The utility model mainly solves the technical problem existing for above-mentioned prior art, provides a kind of new hull of pouring current transformer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of new hull of pouring current transformer, comprise the procapsid and back casing that snap together, be provided with the core cylinder for location current mutual inductor coil in described procapsid, the outside of core barrel body is provided with location fin; Described back casing is provided with core bore, and core bore is provided with detent, and location fin matches with detent and back casing is positioned on procapsid.
As preferably, described back casing is also provided with some type posts be plugged in procapsid die cavity.
Front and rear housings of the present utility model adopts male and female groove fastening structure, coordinates tight, compact, and outward appearance is consistent, is not subject to the impact of environment and cast.During use, first mutual inductor coil is fixed in the front housing, again by resin by injection in the die cavity of procapsid, then upper back casing is fastened, type post on back casing is plugged in resin, when unsaturated-resin solidifies at normal temperatures in short time, front and rear housings and mutual inductor coil are bonded together, form an entirety.Whole process eliminates casting mold, and resin need not heat in an oven, reduces energy consumption; The product design produced is unified, low to the skill set requirements of employee, and save labour, operating efficiency provides more than 2 times.
Adopt front and rear housings of the present utility model, the method of tradition cast is instead of when making instrument transformer, get rid of casting mold and heated oven, can production environment be improved, reduce labour intensity, enhance productivity, and be convenient to realize automated production, and the production cost of product does not significantly improve, also product appearance quality have also been obtained raising simultaneously, has very large social benefit.
Accompanying drawing explanation
Fig. 1 is a kind of perspective view of the present utility model;
Fig. 2 is a kind of Split type structure schematic diagram of the present utility model.
In figure, 1-procapsid, 2-core cylinder, 3-locates fin, 4-back casing, 5-core bore, 6-detent, 7-type post.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1 and Fig. 2, the utility model comprises the procapsid and back casing that snap together, is wherein provided with the core cylinder for location current mutual inductor coil in procapsid, and the outside of core barrel body is provided with location fin; Back casing is provided with core bore, and core bore is provided with detent, and location fin matches with detent and back casing is positioned on procapsid.As further improvement, back casing is also provided with some type posts be plugged in procapsid die cavity.
Front and rear housings of the present utility model adopts male and female groove fastening structure, coordinates tight, compact, and outward appearance is consistent, is not subject to the impact of environment and cast.During use, first mutual inductor coil is fixed in the front housing, again by resin by injection in the die cavity of procapsid, then upper back casing is fastened, type post on back casing is plugged in resin, when unsaturated-resin solidifies at normal temperatures in short time, front and rear housings and mutual inductor coil are bonded together, form an entirety.Whole process eliminates casting mold, and resin need not heat in an oven, reduces energy consumption; The product design produced is unified, low to the skill set requirements of employee, and save labour, operating efficiency provides more than 2 times.
Adopt front and rear housings of the present utility model, the method of tradition cast is instead of when making instrument transformer, get rid of casting mold and heated oven, can production environment be improved, reduce labour intensity, enhance productivity, and be convenient to realize automated production, and the production cost of product does not significantly improve, also product appearance quality have also been obtained raising simultaneously, has very large social benefit.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection range of the present utility model.
