Abstract
The invention relates to a wind-resistant composite insulator, which consists of a bar body and umbrella skirts. Open umbrella skirts are designed, and the root strength of the umbrella skirts is improved. The umbrella skirts are arranged on the periphery of the bar body, and a gradient structure which becomes smaller and smaller from the roots of the umbrella skirts to the tops of the umbrella skirts is used for connecting the sections of the umbrella skirts with the bar body, so that adaptation to borne wind power load is realized, and bending deformation of the umbrella skirts is reduced fully. The umbrella skirts are arranged in an equal-diameter way and an unequal-diameter way. The wind-resistant composite insulator has the advantages of high wind resistance, realization of an anti-ageing and good outer insulating structure under the severe environmental condition of strong wind, prevention of reducing the effective creepage distance of a product, freeness from cleaning and maintaining, long service life, guarantee of safe running of a power system, and remarkable economic benefit and social benefit.
Description
Technical field
The present invention relates to a kind of wind proof composite insulator, belong to electric power transfer unit manufacturing technology field.
Background technology
Suspended compound insulator product at home and abroad, its project organization generally adopts full skirt to possess certain angle of declination structure, mainly increases by considering that sub-umbrella keeps certain dried district in creepage distance and the rainwater situation, with the electric property of raising product.But the product full skirt is subjected to huge wind-force effect in strong wind area, and violent swing can appear in full skirt, and it causes consequence to be: the full skirt root is stressed large, and frequent swing causes root to occur in the short period of time and tear; It two is that gamp acutely swings, and with adjacent full skirt collision, causes the full skirt wearing and tearing and because the full skirt bridge joint, has reduced rapidly effective creep distance of product.This uses the open umbrella shape of novel employing, adopts isometrical umbrella and two kinds of forms of non-isometrical umbrella.Under the expert of graduate school of Tsing-Hua University professor's guidance and help, passed through smoothly harsh wind tunnel test.Result of the test shows, the present invention can effectively address the above problem, and wide market prospects are arranged.
Summary of the invention
The problem that a kind of wind proof composite insulator of the present invention exists according to above insulator, purpose provides a kind of full skirt employing Open architecture, wind resistance is good, under the strong wind severe environmental conditions, can possess anti-aging and good external insulation structure, do not reduce effective creepage distance of product, exempt from cleaning, non-maintaining, the composite insulator that life of product is high.
The technical scheme of a kind of wind proof composite insulator of the present invention: consisted of by barred body and full skirt, design opening full skirt, improve the intensity of full skirt root.Full skirt is arranged in the periphery of barred body, and what the full skirt cross section was connected with barred body consists of for the full skirt root is descending grading structure to the full skirt top, adapts with suffered wind-force load, fully reduces the flexural deformation of full skirt.Full skirt is arranged minute equal diameter full skirt arrangement and the size diameter full skirt is arranged two kinds of forms.
Characteristics of the present invention:
1, full skirt adopts Open architecture, and wind resistance is good;
2, full skirt is arranged minute equal diameter full skirt arrangement and two kinds of forms of size diameter full skirt arrangement;
3, the external insulation performance is good;
4, exempt from cleaning, non-maintaining, improved life of product.
Beneficial effect: the present invention adopts Open architecture, wind resistance good, under the strong wind severe environmental conditions, can possess anti-aging and good external insulation structure, do not reduce effective creepage distance of product, exempt from cleaning, non-maintaining, life of product is high, can guarantee safe operation of power system, economic benefit, social benefit are obvious.

Specific implementation method
The technical scheme of a kind of wind proof composite insulator of the present invention: consisted of by barred body 1 and full skirt 2, design opening full skirt 2, improve the intensity of full skirt root 3.Full skirt 2 is arranged in the periphery of barred body 1, full skirt 2 cross sections be connected with barred body 1 for full skirt root 3 is descending grading structure formation to full skirt top 4, adapt with suffered wind-force load, fully reduce the flexural deformation of full skirt 2.Full skirt 2 is arranged minute equal diameter full skirt arrangement and size diameter full skirt 2 is arranged two kinds of forms.
Be described further below in conjunction with 1 pair of a kind of wind proof composite insulator of the present invention of accompanying drawing equal diameter full skirt arrangement architecture.
A kind of wind proof composite insulator of the present invention equal diameter full skirt arrangement architecture is made of barred body 1 and full skirt 2, designs opening full skirt 2, improves the intensity of full skirt root 3.Full skirt 2 is arranged in the periphery of barred body 1, full skirt 2 cross sections be connected with barred body 1 for full skirt root 3 is descending grading structure formation to full skirt top 4, adapt with suffered wind-force load, fully reduce the flexural deformation of full skirt 2.The full skirt diameter is 85mm, and adjacent two full skirt top spacings are 58mm.
Be described further below in conjunction with 2 pairs of a kind of wind proof composite insulators of the present invention of accompanying drawing size diameter full skirt arrangement architecture.
A kind of wind proof composite insulator of the present invention size diameter full skirt arrangement architecture is made of barred body 1 and full skirt 2, designs opening full skirt 2, improves the intensity of full skirt root 3.Full skirt 2 is arranged in the periphery of barred body 1, full skirt 2 cross sections be connected with barred body 1 for full skirt root 3 is descending grading structure formation to full skirt top 4, adapt with suffered wind-force load, fully reduce the flexural deformation of full skirt 2.Large full skirt diameter is 200 mm, and umbellule skirt diameter is 170 mm, and adjacent big or small two full skirt top spacings are 43 mm.
