Abstract
The invention relates to a porcelain composite insulator and a manufacturing method thereof. The porcelain composite insulator comprises an insulation barrel, flanges or hardware fittings fixed at ends of the insulation barrel, and a porcelain umbrella skirt connected outside a bar body of the insulation barrel, wherein the insulation barrel is a glass fiber coiled enhanced epoxy barrel; and the porcelain umbrella skirt is formed by two or more groups of porcelain umbrella skirt sections which are connected in series with one another. The porcelain composite insulator has high mechanical strength, light weight and high inner insulation intensity; the surface of the porcelain umbrella skirt is treated by a special process; the porcelain composite insulator keeps the advantages of high electric strength, stable running, long service life and the like of a porcelain insulator and has the advantages that: the pollution flashover resistant capability is improved greatly and the shortcoming that the conventional insulator is easy to pollute is overcome; most importantly, the porcelain umbrella skirt is formed by two or more groups of porcelain umbrella skirt sections which are connected in series with one another, so the one-time qualification rate of products during production is increased greatly; therefore, the comprehensive performance of the porcelain composite insulator product is superior; and the porcelain composite insulator has higher popularization value.
Description
Technical field
The present invention relates to a kind of porcelain composite insulator that power industry High-Voltage Electrical Appliances and power transmission and transformation line are used.The present invention also provides a kind of production technology that is used for this porcelain composite insulator, makes product first-time qualification rate in process of production be greatly enhanced.
Background technology
Traditional total ceramic insulator or epoxy glass fiber reinforcing material and the silicon rubber compound insulator of the general use of existing power high voltage electrical equipment and defeated modified line road.The porcelain insulator electric strength is high, and ageing-resistant performance is superior, is still main product at present, is prone to brokenly but exist, and problem such as the voltage levels rate of finished products is very low causes the waste of the high and resource of production cost; Silicon rubber compound insulator resistant sudden strain of a muscle ability is strong, and light weight is applicable to the occasion that gradation for surface pollution is high, but its electric strength is low, loss of properties on aging, and poor stability, there is certain problem in the suspension insulator that in power transmission and transformation line, uses at present.So be necessary to develop new insulator product to satisfy the constantly market demand of development.
Summary of the invention
The technical problem that the present invention will solve provide a kind of when producing product be difficult for scrapping the porcelain composite insulator that can reduce production costs; The present invention also provides a kind of production technology that is used for this porcelain composite insulator, makes product first-time qualification rate in process of production be greatly enhanced.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of porcelain composite insulator; Comprise insulating cylinder, be fixed on the flange or the gold utensil of insulating cylinder end, and be connected the outer porcelain full skirt of insulating cylinder barred body; Its innovative point is: said insulating cylinder is that glass fiber twines the reinforced epoxy tube, and said porcelain full skirt is composed in series by two groups or more porcelain full skirt sections.
Further, said each porcelain full skirt sections serial connection place open annular seal groove.
Further, be provided with both epoxy colloids of bonding between said insulating cylinder and the porcelain full skirt.
The above-mentioned porcelain production process of composite insulator of a kind of manufacturing; Its innovative point is: an end and the flange with insulating cylinder glueds joint fixing earlier; Then the head and the tail of the porcelain full skirt sections more than two or two serial connection cover are successively installed on the insulating cylinder; At each porcelain full skirt sections serial connection place seal groove embedded seal ring, and in the end the end of a joint porcelain full skirt sections is established another flange; Space between insulating cylinder and the porcelain full skirt is evacuated to below the 0.01Mpa, is pressed into the epoxy colloid again insulating cylinder and the splicing of porcelain cluster parachute are one.
Further, the injection pressure position 0.1-0.2Mpa of said epoxy colloid.
The invention has the advantages that: because insulating cylinder adopts the epoxy glass fiber reinforced composite, mechanical strength is high, and in light weight, interior dielectric strength is good; Adopt the surface through special process Treatment of Porcelain full skirt, advantages such as the porcelain insulator electric strength is high, stable except having kept, life-span length, its resistant sudden strain of a muscle ability is greatly enhanced, and has overcome the weakness of the easy pollution flashover of conventional insulators.Most importantly be, the porcelain full skirt is composed in series by two groups or more porcelain full skirt sections, avoids large-scale porcelain full skirt to make always problem, the problem includes: problems such as the production qualification rate is low, price height through one-shot forming.Product first-time qualification rate in process of production is greatly enhanced, thereby makes that porcelain composite insulator product combination property is superior, and very big promotional value is arranged.
Description of drawings
Fig. 1 is a porcelain composite insulator structural representation of the present invention.
Fig. 2 is the porcelain full skirt sections structural representation of porcelain composite insulator of the present invention.
Embodiment
Fig. 1 shows porcelain compound inslation minor structure of the present invention, and insulating cylinder 1 twines the reinforced epoxy tube for glass fiber, and its two ends are fixed with flange 5, is set with the porcelain full skirt outside the insulating cylinder 1, is provided with both epoxy colloids 3 of bonding between insulating cylinder 1 and the porcelain full skirt.
The porcelain full skirt is composed in series by two groups or more porcelain full skirt sections 2, and is as shown in Figure 2, has seal groove at the serial connection place of each porcelain full skirt sections 2, but embedding sealing ring 4 in the sealing groove guarantees the sealed insulation effect when being used for porcelain full skirt sections 2 serial connections.
Make the porcelain compound inslation period of the day from 11 p.m. to 1 a.m of the present invention: an end and the flange 5 with insulating cylinder 1 glueds joint fixing earlier; Then 2 head and the tail of the porcelain full skirt sections more than two or two serial connection cover are successively installed on the insulating cylinder 1; At each porcelain full skirt sections 2 serial connection place seal groove embedded seal ring 4, and in the end the end of a joint porcelain full skirt sections 2 is established another flange; Space between insulating cylinder 1 and the porcelain full skirt is evacuated to below the 0.01Mpa, is pressed into epoxy colloid 3 again insulating cylinder 1 and the splicing of porcelain cluster parachute are one, the injection pressure position 0.1-0.2Mpa of epoxy colloid.
Certainly, the insulating cylinder among the present invention 1 also twines the insulating rod replacement that the reinforced epoxy material is processed by glass fiber.
