Abstract
The utility model discloses a respond to bi -pass sleeve pipe outward, including casing main body, semiconductor rubber, outer inductive layer and central bar copper, the center bar copper is located the casing main body intermediate position, and semiconductor rubber is located casing main body outside intermediate position, semiconductor rubber and the integrative injection moulding of casing main body, respond to level in the semiconductor rubber outside outward. The utility model discloses simple structure, reasonable in design, outer inductive layer is far away apart from central bar copper, and it combines the position can be not so good as the obvious of internal induction layer to the reaction of taking highly compressed central bar copper, in order to remedy the response effect that weakens, extends outer inductive layer to guarantee that outer inductive layer is close to with the internal induction layer on the inductance capacitance, thus on using external display the model can with the market unanimity, simultaneously because outer inductive layer is individual very even circular, so its electric field is very even. Partial discharge can reach 35kv's standard to the quality is very stable.
Description
Technical field
The utility model relates to electrical equipment, specifically a kind of outer induction bilateral sleeve pipe.
Background technology
Because internal induction net and charged copper rod are apart from close in existing bilateral sleeve pipe, the impact of high pressure copper rod is subject to clearly with epoxy resin binding site around it, after being mainly reflected in voltage rise to more than 20kv, the bilateral sleeve pipe of major part internal induction all the office of controlling can not put effect very well, and this just have impact on the qualification rate of bilateral sleeve pipe at more than 35kv.In addition internal induction scheme overlaps tube outside because needs thread stretches out, the external electrification display of convenient connection, so the certain depth of brass inserts protruding separately have impact on the electric field of internal induction net, cause the uneven of electric field, the upper limit that the office that this element equally also can have influence on internal induction sleeve pipe puts.
Utility model content
The purpose of this utility model is to provide a kind of outer induction bilateral sleeve pipe, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of outer induction bilateral sleeve pipe, comprises casing main body, semi-conducting rubber, outer inductive layer and center copper rod; Described center copper rod is positioned at casing main body centre position, and semi-conducting rubber is positioned at centre position outside casing main body, semi-conducting rubber and casing main body integrated injection molding; Outer inductive layer is positioned at outside semi-conducting rubber.
As further program of the utility model: described casing main body is epoxy resin material.
As the utility model further scheme: described casing main body centre position is provided with internal induction net.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, outer inductive layer distance center copper rod is far away, its binding site can be not so good as the obvious of internal induction layer to the reaction of the center copper rod of band high pressure, in order to make up the inductive effects weakened, is extended by outer inductive layer, to guarantee that outer inductive layer is close with internal induction layer on inductance capacitance, thus model can be consistent with market on use external-connection displayer; Simultaneously because outer inductive layer is a very uniform circle, so its electric field is very even.Shelf depreciation can reach the standard of 35kv, and quality is highly stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation installing pressing plate in the utility model.
Fig. 3 is the structural representation of semi-conducting rubber in the utility model.
In figure: 1-casing main body, 2-semi-conducting rubber, the outer inductive layer of 3-, 4-center copper rod, 5-installs pressing plate.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, a kind of outer induction bilateral sleeve pipe, comprises casing main body 1, semi-conducting rubber 2, outer inductive layer 3 and center copper rod 4; Described center copper rod 4 is positioned at casing main body 1 centre position, and semi-conducting rubber 2 is positioned at centre position outside casing main body 1, semi-conducting rubber 2 and casing main body 1 integrated injection molding; Outer inductive layer 3 is positioned at outside semi-conducting rubber 2.
Further, casing main body 1 described in the utility model is epoxy resin material.
Further, casing main body 1 centre position described in the utility model is provided with internal induction net.
External wiring way of the present utility model needs to realize by installing pressing plate 5, pressing plate 5 is installed directly contact with outer inductive layer 3, and the current information sensed passes to electrification display by installing pressing plate 5, pressing plate 5 is installed and has carried out corrosion treatment with the surface of contact of outer inductive layer 3, guarantee that conductive layer necessarily has several contact points to contact well with installation pressing plate 5, and guarantee these contact point contact stabilizations.
Principle of work of the present utility model is:
Make the semi-conducting rubber 2 of a bilateral sleeve pipe induction coil region outline, then semi-conducting rubber 2 is positioned in bilateral ferrule mold with casing main body 1 simultaneously injection mo(u)lding, semi-conducting rubber 2 can be combined as a whole with casing main body 1, because this semi-conducting rubber 2 has conductive effect, so it can sense the electric current of center copper rod 4, with inductance capacitance, the electric capacity of capacitance and internal induction net is close, therefore can play the effect of the external electrification display of internal induction net.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
