Abstract

The utility model discloses a thin umbrella-type electric porcelain insulator used in a power transmission line. The thin umbrella-type electric porcelain insulator comprises a porcelain body and an umbrella on the body, and the thickness of the part of the umbrella, which is connected with the porcelain body, ranges from 9mm to 12 mm; and the ratio of the thickness of the part of the umbrella, which is connected with the porcelain body, to the thickness of the outer edge of the umbrella ranges from 1.2-1.35: 1. By reasonably reducing the thickness of the umbrella of the product, the thickness of the part of the umbrella, which is connected with the porcelain body, is half of the thickness of the commonly designed umbrella after the reduction of thickness. With no influence on the product quality, the thin umbrella-type electric porcelain insulator reduces the consumption of clay, saves the production cost, and simultaneously greatly reduces the product weight. Even though the thickness of the umbrella is reduced, the stem diameter of the body of the product is not changed, therefore, the mechanical strength and the insulating property of the product are not influenced; and simultaneously, the thin umbrella-type electric porcelain insulator is convenient to be transported and assembled, thereby reducing the labor intensity.

Description

Thin umbrella umbrella shape electric porcelain insulator

One, technical field

The utility model relates to the electric porcelain insulator that uses in the transmission line, specifically is the improvement to the electric porcelain insulator umbrella shape.

Two, background technology

Electrotechnical porcelain product all is made up of porcelain spare main body and a lot of groups of peripheral umbrellas thereof, and the cluster parachute structure is effective facility that porcelain spare remains on insulation property under the various service conditionss, protection electric equipment.The umbrella shape of electrotechnical porcelain product design at present: the umbrella thickness partly that links to each other with porcelain spare main body is 18mm～25mm, and umbrella root is 1.5～2.0: 1 with the ratio of the thickness on umbrella limit.Product needed consumes a large amount of mudstone raw materials, simultaneously, and the thicker weight that also has influence on product of umbrella shape.Along with the makers' continuous rise of each electroceramics, it is more and more tired to produce the used mudstone raw material of electroceramics, and the mineral resources in a lot of areas presents rareness, makes the mudstone cost of material go up, and production cost increases.

Three, summary of the invention

The purpose of this utility model provides a kind of thin umbrella umbrella shape electric porcelain insulator, with conservation and reduce product weight.

The technical solution adopted in the utility model is: thin umbrella umbrella shape electric porcelain insulator comprises the umbrella on porcelain spare main body and the main body, and the thickness of umbrella and porcelain spare main body connection is 9mm～12mm; The thickness of umbrella and porcelain spare main body connection is 1.2～1.35: 1 with the ratio of the thickness of umbrella outer rim.

By with the reasonable attenuate of the umbrella of product, link to each other with the porcelain spare main body thickness of part of umbrella is generally to design 1/2 of umbrella shape thickness behind the attenuate.Do not influencing under the product quality premise, reducing the consumption of pug, saving production cost, and product weight is reduced.After the umbrella attenuate, small product size and overall weight reduce, and product main body bar footpath does not change, so can not influence the mechanical strength and the insulation property of product, are convenient to transportation and assembling simultaneously, have alleviated labour intensity.

Fig. 4 is the partial enlarged drawing of Fig. 3.

Five, embodiment

Fig. 1 is the insulator that the umbrella shape of not attenuate is produced, and the umbrella thickness partly that links to each other with porcelain spare main body is 20mm, and the quality of entire product is 42.56kg; Fig. 3 is the insulator that the umbrella shape behind the attenuate is produced, and the umbrella thickness partly that links to each other with porcelain spare main body is 10mm, and the quality of entire product is 40.32 kilograms, and both thickness ratios are 2: 1, and both differ 5% at quality.Porcelain spare of same original production needs 800kg mud, and only needs 760kg now, has saved 40kg.If annual electroceramics factory produces 5000 tons of electroceramics, adopt thin umbrella shape can save about 250 tons of mud, thereby reduced production cost.

Thin umbrella product any problem do not occur through the practical application check.

Claims

1. a thin umbrella umbrella shape electric porcelain insulator comprises the umbrella on porcelain spare main body and the main body, it is characterized in that: the thickness of umbrella and porcelain spare main body connection is 9mm～12mm.

2. thin umbrella umbrella shape electric porcelain insulator according to claim 1 is characterized in that: the thickness of umbrella and porcelain spare main body connection is 1.2～1.35: 1 with the ratio of the thickness of umbrella outer rim.
