Abstract
The utility model relates to a novel dry-type high-voltage sleeve used on an outgoing line of a transformer and a penetrating wall of a transformer station, comprising a wiring terminal, a primary conductor connected with the wiring terminal, and an outer insulation sheath arranged outside the primary conductor. The outer insulation sheath is arranged on a rigidity framework outside the primary conductor, and sequentially comprises a buffering layer, an insulation layer, a capacitance screen, a transitional protecting layer and an outer insulation layer at the outermost layer from inside to outside, wherein the outer insulation layer is shaped integrally by the expansion and chilling shrinkage of fluorous rubber, and large umbrella skirts and small umbrella skirts with the material the same as that of the outer insulation layer are arranged on the outer insulation layer in sequence. In the utility model, outer sheaths at two ends adopt a specialized design formula, namely the fluorus rubber, so that the product weight is greatly lightened, the structure is light and smart, the high-temperature oil and corrosion of the transformer can be resisted, and the quality is stable; and the fluorous rubber has constant elasticity, and is sheathed outside a main-insulation capacitance core, thus increasing creep distance, and playing a role in protecting the main-insulation capacitance core. The outer insulation layer and the large umbrella skirts as well as the small umbrella skirts are combined into whole, so that the electrical performance and the sealing performance are good.
Description
Technical field
The utility model relates to bushing, refers in particular to a kind of transformer outlet and transformer station New Dry Type High Tension sleeve pipe on through walls that is used in.
Background technology
The sleeve pipe overwhelming majority who uses in the electric power system at present is traditional filling type porcelain overcoat sleeve pipe, small part is a glass fibre epoxy resin dipping formula sleeve pipe in addition, the filling type sleeve pipe is because in mentality of designing, the limitation of material use and technological equipment, there is oil leaking pollution product in itself, mechanical strength is low, sealing property and barrier propterty are poor, explosive, jeopardize the person and device security, can not satisfy the miniaturization that power department proposes the high-voltage electrical apparatus product, no oiling, the instructions for use of non-maintaining and high reliability.Glass fibre epoxy resin dipping formula sleeve pipe adopts epoxy resin cure to form, and easily forms air gap during because of epoxy resin cure, influences the product insulation property, Gu epoxy resin as insulating material, major applications is not higher than in the power product of 35KV in electric pressure.
Summary of the invention
The purpose of this utility model be at the shortcoming that exists in the background technology and problem in addition novelty improve, a kind of monolithic molding is provided, no gap, good seal can be non-maintaining, the New Dry Type High Tension sleeve pipe of dependable performance.
Technical solutions of the utility model are a kind of terminals that comprise of structure; the Primary Conductor that is connected with terminals; and be arranged on the outer insulation oversheath of Primary Conductor; its described insulation oversheath is arranged on the outer steel frame of Primary Conductor; comprise resilient coating, insulating barrier, capacitance plate, over current protection layer from the inside to the outside successively and be arranged on outermost external insulation layer; wherein: external insulation layer is a fluorubber expansion shrinkage monolithic molding, also is arranged with the large and small full skirt with the external insulation layer same material on the external insulation layer in regular turn.
Advantage of the present utility model and beneficial effect:
The utility model bushing two ends oversheath all adopts unique special designs prescription fluorubber, be used for instead of glass fibrage epoxide resin material and ordinary silicon rubber outer protection cover, porcelain bushing, can alleviate product weight greatly, structure is light and handy, when being used for transformer, but transformer oil resistant high temperature and corrosion, steady quality.And this prescription fluorubber also has constant elasticity, is placed in outside the main insulation capacitance core, increases creep distance, and the effect of protection capacitance core main insulation is arranged.External insulation layer of the present utility model and large and small full skirt are an integral body, by the high temperature vulcanized global formation of secondary, piece electrical function admirable, good airproof performance.
Description of drawings

Fig. 2 is the broken section structural representation.
Embodiment
By Fig. 1,2 as can be known; the utility model comprises terminals 1; the Primary Conductor 3 that is connected with terminals 1; and be arranged on the outer insulation oversheath of Primary Conductor 3; its described insulation oversheath is arranged on Primary Conductor 3 steel frame 5 outward; comprise resilient coating 6, insulating barrier 7, capacitance plate 8, over current protection layer 9 from the inside to the outside successively and be arranged on outermost external insulation layer 10; wherein: external insulation layer 10 also is arranged with the large and small full skirt 11,12 with external insulation layer 10 same materials in regular turn for fluorubber expansion shrinkage monolithic molding on the external insulation layer 10.
Insulation oversheath described in the utility model middle part or inclined to one side middle part are set with flange 13, flange 13 is provided with measuring lead wire 14, the length of flange 13 both sides dry-type high-voltage sleeve pipes is that equivalent is divided setting equally, or inequality segmentation setting, and the both sides of flange 13 all can be provided with current transformer.Described steel frame 5 two ends are provided with grading shield 4 and Primary Conductor fixture 2.Described capacitance plate 8 is electric conductor and semiconductor and the compound body of making of insulating material.Described external insulation layer 10 is an integral body with large and small full skirt 11,12, by the high temperature vulcanized compression molding of secondary.Bushing can be designed as the cable formula of wearing, and perhaps conducts electricity rod-type.
Structural principle of the present utility model:
The utility model is made insulating barrier by system controlled by computer by the requirement of designing program on steel frame, adopt electric conductor and semiconductor and insulating material to make capacitance plate, and insulating barrier and capacitance plate are alternately made the formation capacitive and all pressed main insulating layer.External insulation adopts high resiliency, and is high temperature resistant, and corrosion resistant unique formula fluorubber monolithic molding cuts off on the layer to main in shrinkage after the expansion.It between main insulation and external insulation layer the over current protection layer.Because of external insulation has shrinkage elasticity, the contraction protection pressure of constant is arranged at normal temperatures, whole interface is in conjunction with tight no gap, good airproof performance.The big or small full skirt that has different size and quantity on the external insulation as required, big or small full skirt is arranged at interval in regular turn, with outer insulation jacket be the overall structure of same material.Flange adopts not magnetic conduction, high-intensity cast aluminum alloy material to make, and overall fixed is in the sleeve pipe middle part.Or flange is provided with earth terminal, when partial discharge and dielectric loss test it untied as measuring lead wire reliable ground when normally moving.
