Abstract
The utility model relates to a porcelain composite insulator, which comprises an insulating cylinder, a flange or hardware fitting fixed at the end part of the insulating cylinder, and a porcelain umbrella skirt connected to the outer part of a stick body of the insulating cylinder, wherein, the insulating cylinder adopts a glass fiber winding reinforced epoxy cylinder, and the porcelain umbrella skirt is composed of two groups or more than two groups of serially-connected porcelain umbrella skirt sections. The utility model has high mechanical strength, light weight and good inner insulating strength; the porcelain umbrella skirt, of which the surface is processed through special technology, is adopted, so that in addition to the advantages of high electric strength, stability of operation, long service life and the like, the porcelain insulator is greatly improved in contamination resistant capability, and the detect of easy contamination of the traditional insulator is overcome; and above all, the porcelain umbrella skirt is composed of two groups or more than two groups of serially-connected porcelain umbrella skirt sections, so that the primary qualification rate of products is greatly improved during the production process; therefore, the porcelain composite insulator has superior comprehensive property and great popularization value.
Description
Technical field
The utility model relates to a kind of porcelain composite insulator that power industry High-Voltage Electrical Appliances and power transmission and transformation line are used, particularly a kind of when producing product be difficult for scrapping the porcelain composite insulator that can reduce production costs.
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.Porcelain insulator electric strength height, ageing-resistant performance is superior, is still main product at present, but exists easily brokenly, 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 uses in power transmission and transformation line at present.So be necessary to develop new insulator product to satisfy the constantly market demand of development.
The utility model content
The technical problems to be solved in the utility model provide a kind of when producing product be difficult for scrapping the porcelain composite insulator that can reduce production costs.
For solving the problems of the technologies described above, the technical solution of the utility model 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: described insulating cylinder is that glass fibre twines the reinforced epoxy tube, and described porcelain full skirt is composed in series by two groups or more porcelain full skirt sections.
Further, described each porcelain full skirt sections serial connection place open annular seal groove.
Further, be provided with both epoxy colloids of bonding between described insulating cylinder and the porcelain full skirt.
Advantage of the present utility model is: because insulating cylinder adopts the epoxy glass fiber reinforced composite, and the mechanical strength height, in light weight, interior dielectric strength is good; Adopt the surface to handle the porcelain full skirt through special process, except having kept porcelain insulator electric strength height, stable, advantage such as the life-span is long, 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 by 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 the utility model porcelain composite insulator structural representation.
Fig. 2 is the porcelain full skirt sections structural representation of the utility model porcelain composite insulator.
Embodiment
Fig. 1 shows porcelain compound inslation minor structure of the present utility model, and insulating cylinder 1 twines the reinforced epoxy tube for glass fibre, 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, 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 utility model: 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 of epoxy colloid is 0.1-0.2Mpa.
Certainly, the insulating cylinder in the utility model 1 also twines the insulating rod replacement that the reinforced epoxy material is made by glass fibre.
Claims (3)
1. 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, it is characterized in that: described insulating cylinder is that glass fibre twines the reinforced epoxy tube, and described porcelain full skirt is composed in series by two groups or more porcelain full skirt sections.
2. porcelain composite insulator according to claim 1 is characterized in that: described each porcelain full skirt sections serial connection place open annular seal groove.
