Abstract

The utility model relates to a high-voltage transmission and transformation equipment, in particular to a composite insulator, comprising at least an insulator body (7), a ceramic element (1) on the body (7), and a silicone rubber shed (3). The utility model is characterized in that the outside of the ceramic element (1) of the insulator body (7) is sleeved with an integrated silicone rubber shed (3). Because the composite insulator adopts integrated injection molding process on the silicone rubber shed housing, the producing procedure is simplified, the mechanization and automatization degree are improved, the labor intensity of workers is lowered, the production efficiency is greatly increased, and the product appearance and quality are also improved. At the same time, the flange design at the bonding between the silicone rubber sheds is eliminated, thereby solving the defect of easy dirt accumulation and difficult cleaning, and eliminating the hidden dangers of running brought by an interface.

Description

A kind of composite insulator

Technical field

The utility model relates to a kind of high voltage power transmission and transforming equipment, particularly a kind of composite insulator.

Background technology

Chinese patent (ZL 00 2 26500.1) discloses a kind of excellent t shore (porcelain core) composite insulator, as shown in Figure 1, it is by being added with sheath 2 at porcelain spare 1 skin, sheath 2 outer silicon rubber full skirt 3 moulding with different size constitute, owing to exist between the silicon rubber full skirt contact-making surface 4 and the sticking and interface 5 of silicon rubber full skirt and silicone rubber jacket, flange 6 designs are adopted in the abutting edge between the silicon rubber full skirt, thereby make between the silicon rubber full skirt 4, the sticking and easy contamination in interface 5 and flange 6 places, difficult cleaning brings hidden danger to operation.Secondly, exist the porcelain core rod to add that silicon rubber umbrella cover technology is loaded down with trivial details, technological requirement is high, the manual operation amount is big, labor strength is high, production efficiency is low aborning, be difficult to form shortcoming such as large-scale production; Be in operation, owing to be the production of single full skirt technique for sticking, have many sticking and interfaces, and be manual operation, the difference in operation during it is produced makes operation hidden danger bigger.

Summary of the invention

The purpose of this utility model provides a kind of composite insulator, its production technology is simple, easy cleaning, safe and reliable to operation, labor strength is low, production efficiency is high.

The purpose of this utility model is achieved in that a kind of composite insulator, which comprises at least insulator body 7, and porcelain spare 1 on the body 7 and silicon rubber full skirt 3 is characterized in that: the porcelain spare 1 outer silicon rubber full skirt 3 that is with integral structure of edge body 7.

The utility model has the advantages that: because the silicon rubber umbrella cover is adopted the general injection die press technology for forming, simplified production process, mechanization, automaticity height have reduced labor strength, have increased substantially production efficiency, have improved the product appearance quality.And owing to do not exist between the silicon rubber full skirt and the gluing and the interface of silicon rubber full skirt and silicone rubber jacket, removed the flange design of abutting edge between the silicon rubber full skirt simultaneously, thereby make this locate easy contamination, the defective of difficult cleaning is solved, and has eliminated the operation hidden danger that bring at the interface.

Description of drawings

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.

Fig. 1 is the partial structurtes schematic diagram of prior art;

Fig. 2 is the utility model embodiment partial structurtes schematic diagrames.

Among the figure: 1, porcelain spare; 2, sheath; 3, silicon rubber full skirt; 4, silicon rubber full skirt contact-making surface; 5, sticking and interface; 6, flange; 7, body.

Embodiment

Embodiment as shown in Figure 2, which comprises at least insulator body 7, porcelain spare 1 on body 7 and silicon rubber full skirt 3, the porcelain spare 1 outer silicon rubber full skirt 3 that is with integral structure of edge body 7, because the silicon rubber umbrella cover of integral structure adopts general injection mold pressing one-shot forming technique, contrasts two figure and can find that the utility model has following advantage:

1, operation reduces, and production efficiency is improved;

2, eliminated the bonded adhesives performance than umbrella cover material property difference band come the operation hidden danger;

3, cancelled the flange design of abutting edge between the silicon rubber full skirt, thereby made this locate easy contamination, the defective of difficult cleaning is solved, and has eliminated the operation hidden danger that bring at the interface.

The mode that this product adopts the production process of composite insulator of traditional porcelain insulator production technology and development day by day to combine, feasibility is abundant, the clavate post composite insulator of this explained hereafter has been tried out well, and to expanding insulator production technology approach certain realistic meaning is arranged.Along with a large amount of uses of composite insulator, will embody its superior performance and huge economic benefit.

Claims (1)

1, a kind of composite insulator which comprises at least insulator body (7), and porcelain spare (1) on the body (7) and silicon rubber full skirt (3) is characterized in that: the outer silicon rubber full skirt (3) that is with integral structure of the porcelain spare (1) of edge body (7).
