Abstract

An organic composite insulator comprises a mandril, an umbrella cover, and an electric metal, which is characterized in that the umbrella cover is formed by the permutation and combination of three different umbrella bodies with different diameters in some order. The new type insulator can effectively increases creepage distance, distinctly reduce no light interval flashover, and enhance the ability of damp and dirty resistance, which is especially applicable to the insulator with voltage rating above 10 KV.

Description

A kind of novel organic composite insulator

The utility model relates to a kind of power equipment, and particularly a kind of rated voltage is at 1KV or above organic composite insulator.

Organic composite insulator generally constitutes (as shown in Figure 1) by plug (1), silicon rubber outer umbrella sleeve (2) and end gold utensil (3).Plug (1) and silicon rubber outer umbrella sleeve (2) are insulating parts, and end gold utensil (3) is assemblied in one with insulating part, use as installing to connect.Present international organic composite insulator umbrella skirt construction has isometrical umbrella structure (as shown in Figure 4), big umbellule structure (shown in Fig. 2,3).In the hanging net operation process, the more frequent no bright flashover that belongs to external insulation structure gap character appears in the composite insulator of these umbrella skirt constructions, and this flashover is mainly owing to unreasonable the causing of composite insulator external insulation surface texture shape.

The purpose of this utility model is to provide a kind of novel umbrella skirt construction, and this novel umbrella skirt construction can obviously reduce the full skirt edge effect, and helping reducing composite insulator does not have central bay crack flashover.

Above-mentioned purpose of the present utility model is achieved in that the outer umbrella sleeve (2) that forms three kinds of different-diameters with the silicon rubber pressure injection, be gamp (21), middle umbrella (22) and umbellule (23), then it formed the umbrella skirt construction of the five umbrellas combination of umbrella (22), a umbellule (23) and a gamp (21) in a gamp (21), the umbellule (23).This umbellate form is about 10 ° at original full skirt top rade, and does not have on the basis on the edge of dripping and increased the full skirt diameter, has increased the umbrella spacing, and its protective ratio (S/L) is between 2.0-2.5.(press: protective ratio S/L refers to the ratio of creepage distance S and each the shortest fold line distance L in umbrella edge.See Fig. 6)

Advantage of the present utility model is:

1, can obviously reduce composite insulator and not have central bay crack flashover;

2, can increase creepage distance effectively;

3, further strengthened the filthy ability of moisture-proof of composite insulator.

Below in conjunction with the description of the drawings and embodiment, the utility model will be further described:

Fig. 1 is the structural representation of existing organic composite insulator;

Fig. 2 is small one and large one umbrella skirt construction schematic diagram;

Fig. 3 is big two umbellule skirt structural representations; Fig. 4 is isometrical umbrella skirt construction schematic diagram; Fig. 5 is five a umbrellas combination full skirt structural representation of the present utility model; Fig. 6 is the schematic diagram of protective ratio S/L.

Embodiment: the organic composite insulator of a kind of 10KV of rated voltage, plug (1) by the epoxy glass laminate manufacturing, silicon rubber outer umbrella sleeve (2) and two ends gold utensil (3) constitute, wherein outer umbrella sleeve (2) is a kind of umbrella body by large, medium and small three kinds of different-diameters, arrange the full skirt that forms according to a certain order, it is arranged as umbrella (22), a umbellule (23), a gamp (21) in a gamp (21), the umbellule (23).

Claims

1, a kind of novel organic composite insulator, constitute by plug (1), silicon rubber outer umbrella sleeve (2) and both ends gold utensil (3), it is characterized in that, outer umbrella sleeve (2), by the umbrella body of three kinds of different-diameters, i.e. the umbrella skirt construction that rearranges according to a certain order of gamp (21), middle umbrella (22) and umbellule (23).

2, novel organic composite insulator according to claim 1 is characterized in that the order of the umbrella skirt construction of outer umbrella sleeve (2) is arranged, and can be umbrella (22), a umbellule (23), a gamp (21) in a gamp (21), the umbellule (23), successively.
