Abstract
本实用新型属于架空输电线路领域，特别公开了一种架空输电线路用的复合绝缘子，包括位于中心的环氧树脂玻璃纤维棒、包覆环氧树脂玻璃纤维棒的护套、突出于护套表面的若干伞裙和位于端部的金属连接件；伞裙为流线形的盘状体，若干伞裙大小不尽相同；伞裙的边沿设置一条以上的防污槽；复合绝缘子的端部设有金具开槽口；伞裙与护套为一体成型式结构。本实用新型的有益效果：与瓷绝缘子不同，采用环氧树脂玻璃纤维棒的复合绝缘子具有零值自爆的绝缘自我淘汰能力，无需对其进行绝缘测试，具有长期稳定的机电性能和较长的使用寿命；在复合绝缘子的伞裙边沿添加数道防污槽后，可增加爬电距离、防污、增加耐污闪能力。
The utility model belongs to the field of overhead power transmission lines, and particularly discloses a composite insulator for overhead power transmission lines, which comprises an epoxy resin glass fiber rod in the center, a sheath covering the epoxy resin glass fiber rod, and a sheath protruding from the surface of the sheath. Several sheds and metal connectors at the ends; the sheds are streamlined discs, and several sheds are of different sizes; the edge of the sheds is provided with more than one anti-fouling groove; the end of the composite insulator is provided with There are notches for metal fittings; the umbrella skirt and the sheath are integrally formed. Beneficial effects of the utility model: Different from porcelain insulators, composite insulators using epoxy resin glass fiber rods have zero-value self-explosion insulation self-elimination capabilities, no need for insulation tests, and long-term stable electromechanical performance and long service life. Long life; after adding several antifouling grooves on the edge of the shed of the composite insulator, the creepage distance, antifouling, and pollution flashover resistance can be increased.
Description
Technical field
The utility model belongs to field of overhead power transmission lines, discloses the composite insulator that a kind of overhead transmission line is used especially.
Background technology
Line insulator is the insulating element that fixing cord is used in the electric line, is common in electric pole, high-tension bus-bar connection tower, is processed by pottery usually.Ceramic insulator belongs to can the puncture type; It utilizes cement that physics, the different porcelain spare of chemical property are constituted with the metalwork mucilage binding; In the effect that stands the sunlight of electric field, mechanical load and the Nature, wind, rain, snow, mist etc. for a long time; Can be progressively deterioration, the safe operation of electrical network is brought threat, when particularly containing the insulator string generation flashover (owing to reasons such as thunderbolt or pollution flashovers) of deterioration insulator; May make the insulator head moment heating blast of deterioration, the accident that causes lead to land.In addition, adhere at insulator surface, form path and be insulated sub-voltage puncture, need to increase the creep distance of insulator in order to prevent filths such as floating dust.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provide a kind of increase the insulator creepage distance with antifouling anti-puncture, have the electromechanical properties steady in a long-term and the composite insulator in long useful life.
To achieve these goals; The technical scheme that the utility model adopted is: composite insulator is characterized in that: comprise the epoxy resin fiberglass rod that is positioned at the center, coated epoxy resin Fiber glass rod sheath, protrude in some full skirts of jacket surface and be positioned at the metal connecting piece of end.
Aforesaid composite insulator, described full skirt are fusiform discoid body, and some full skirt sizes are not quite similar.
Aforesaid composite insulator, the edge of described full skirt are provided with the antifouling groove more than.
Aforesaid composite insulator, the end of described composite insulator is provided with the gold utensil otch.
Aforesaid composite insulator, described full skirt and the sheath formula structure that is formed in one.
The beneficial effect of the utility model: different with porcelain insulator; Adopt the composite insulator of epoxy resin fiberglass rod to have the superseded ability of insulation oneself of null value self-destruction; Need not it is carried out Insulation test, have electromechanical properties steady in a long-term and long useful life; After the full skirt edge of composite insulator adds several antifouling groove, can increase creepage distance, antifouling, increase resistant sudden strain of a muscle ability.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1 epoxy resin fiberglass rod, 2 sheaths, 3 full skirts, 4 antifouling grooves, 5 gold utensil otch, 6 metal connecting pieces.
Embodiment
Fig. 1 is the preferred embodiment of the utility model, below in conjunction with accompanying drawing the utility model is further described.
According to Fig. 1, composite insulator is characterized in that: comprise the epoxy resin fiberglass rod 1 that is positioned at the center, coated epoxy resin Fiber glass rod 1 sheath 2, protrude in some full skirts 3 on sheath 2 surfaces and be positioned at the metal connecting piece 6 of end; Full skirt 3 is fusiform discoid body, and some full skirt 3 sizes are not quite similar; The edge of full skirt 3 is provided with the antifouling groove 4 more than; The end of composite insulator is provided with gold utensil otch 5; Full skirt 3 and the sheath 2 formula structure that is formed in one.
Different with porcelain insulator, adopt the composite insulator of epoxy resin fiberglass rod to have the superseded ability of insulation oneself of null value self-destruction, need not it is carried out Insulation test, have electromechanical properties steady in a long-term and long useful life; After the full skirt edge of composite insulator adds several antifouling groove, can increase creepage distance, antifouling, increase resistant sudden strain of a muscle ability.
For the workmanship of strictness assurance composite insulator, need note at aspects such as plug choices of raw materials, production process of composite insulator, external insulation designs.Plug should carry out screening test and should the choose reasonable diameter of mandrel; In the different mechanical strength of zones of different design of composite insulator, the plug screening test comprises permeability test, water diffusion test, anticorrosion stress-resistant test, light check, power frequency withstand test, heatproof test.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drops on the protection range of the utility model.
