Abstract
The utility model discloses a high-voltage hollow composite insulator, belonging to the field of high voltage power insulation, which comprises an insulation cylinder, a shed formed on the insulation cylinder, and an upper flange and a lower flange which are arranged at both ends of the insulation cylinder. The utility model is characterized in that: a ring groove is arranged at the outer wall of the flange close to the shed; an insulation sheath is arranged between the ring groove and the shed. The utility model has the advantages of improving appearance quality and reducing the electric erosion on the surface of the flanges based on improving the sealing between the shed and the flange.
Description
Technical field
The utility model relates to high-tension electricity insulation field, particularly a kind of high-pressure hollow combined insulator.
Technical background
At present, the hollow combined insulator structure comprises insulating cylinder, injection moulding silicon rubber umbrella cover, the upper and lower flange of insulating cylinder two ends mucilage binding on insulating cylinder, and manual sealing is adopted in the sealing of umbrella cover and flange interface.Because manual sealing is adopted in the sealing of umbrella cover and flange interface, exist umbrella cover and flange seal bad, it is poor to stand long-term extraneous erosiveness, influence the useful life of hollow combined insulator, especially presentation quality can not guarantee, when the local field strength of hollow combined insulator erecting bed was big, the flange surface galvanic corrosion was decreased serious, influences reliability of products.
Summary of the invention
Technical problem to be solved of the present utility model is to provide a kind of high-pressure hollow combined insulator, and it can improve on the sealing basis of umbrella cover and flange, improves presentation quality, alleviates the flange surface galvanic corrosion and decreases.
In order to solve the problems of the technologies described above, the technical solution of the utility model: two flanges up and down that comprise insulating cylinder, are molded over the umbrella cover on the insulating cylinder and are installed in the insulating cylinder two ends, it is characterized in that the outer wall of described flange is provided with annular groove, be provided with insulating sleeve between annular groove and the umbrella cover.
Further improvement of the utility model also comprises: described annular groove has multiple tracks; Described insulating sleeve and umbrella cover overlap.Be more preferably described insulating sleeve and umbrella cover and all adopt silicon rubber, and be shaped to one; Preferably annular groove is the dovetail structure.
The utility model is provided with insulating sleeve by annular groove is set between annular groove and the umbrella cover on flange, solved the sealing problem between umbrella cover and the flange; And insulating sleeve and umbrella cover overlap or become one, good seal not only, and presentation quality guarantees easily, alleviates the flange surface galvanic corrosion and decreases, and also plays the effect of reinforcement flange and umbrella cover, insulating cylinder, and annular groove is the dovetail structure, and above-mentioned effect is more obvious.
Description of drawings
Fig. 1 is existing high-pressure hollow combined insulator partial cutaway figure;
Fig. 2 is partial cutaway figure of the present utility model;
Fig. 3 is a structure chart of the present utility model.
Embodiment
With reference to Fig. 1, existing high-pressure hollow combined insulator comprises flange 1, silicon rubber umbrella cover 2, insulating cylinder 3.Injection moulding has silicon rubber umbrella cover 2 on the insulating cylinder 3, and mucilage binding has flange 1 in the insulating cylinder end, and silicon rubber umbrella cover 2 adopts manual sealing with the sealing of the interface 4 of flange 1.
With reference to Fig. 2, Fig. 3, offer annular groove 5 at flange 1 near on the outer wall of umbrella cover end, form insulating sleeve 6 between annular groove 5 and the umbrella cover 2.Insulating sleeve 6 covers annular groove 5, and overlaps with umbrella cover 2.Better way is that insulating sleeve 6 and umbrella cover 2 all adopt silicon rubber, and overlaps with umbrella cover 2; Preferably insulating sleeve 6 and umbrella cover 2 are made of one, and annular groove 5 is the dovetail structure, good seal not only, and surface no seam, smooth, smooth, presentation quality is good, can alleviate flange surface galvanic corrosion damage, but also plays the effect of reinforcement flange and umbrella cover, insulating cylinder.For good sealing effect, annular groove 5 can be 1 road, 2 roads, even is multiple tracks.
Claims (4)
1, a kind of hollow combined insulator, two flanges up and down that comprise insulating cylinder, are molded over the umbrella cover on the insulating cylinder and are installed in the insulating cylinder two ends is characterized in that the outer wall of described flange is provided with annular groove, are provided with insulating sleeve between annular groove and the umbrella cover.
2, a kind of hollow combined insulator according to claim 1 is characterized in that, described annular groove has multiple tracks.
