Abstract
The utility model belongs to electric power transmission equipment field, concretely relates to big creep distance three -layer umbrella toughened glass insulator. The utility model provides a neotype many umbellate forms glass insulator because it has open type, many umbellate forms, long -pending dirty unique advantage such as less, easily clean, consequently more is suitable for the serious area of pollution flashover and uses. Through the means such as size combination in umbrella structure molding, big or small umbrella disk footpath, a big creep distance three -layer umbrella toughened glass insulator has been invented.
Description
Technical field
The utility model belongs to electric power conveying equipment field, is specifically related to a kind of large distance three layers of umbrella toughened glass insulator.
Background technology
As insulator high voltage power transmission and transforming circuit playing electric insulation, mechanical connection and carrying conductor load multiple action, in high pressure, UHV transmission device systems, there is special significance.
Many umbellate forms toughened glass insulator researches and develops trial-production the earliest abroad, and large-scale production is near during the last ten years in China's realization, and development speed is faster, and quality level is higher.At present, the glass insulator production technology level of China maintains the leading position in the whole world, in order to promote the Standardization Construction of many umbellate forms glass insulator product, China Electricity Council " transmission of electricity coorporative network insulator expert group ", repeatedly hold the seminar of many umbellate forms glass insulation substandard, carried out discussing fully and reaching common understanding to the electromechanical properties and technical standard etc. of the beveled structure of many umbellate forms glass insulator, creepage distance, structure height and product.
But the bell-shaped glass insulator that current ultra-high-tension power transmission line generally uses the problems such as the lower anti-pollution characteristic of self-cleaning ability is lower due to reason ubiquities such as umbrella-shaped structures, limit the application of glass insulator in superhigh pressure and UHV transmission field.
For these reasons, a kind of how guarantee of design invention just seems particularly necessary at the insulator of pollution severity regional safety stable operation.The application, have employed three umbellate form umbrella disk moulding, in the middle of upper subumbrella rib, add comparatively umbellule rib, and the length distance in appropriate design between the angle of Rhizoma Sparganii and each umbrella rib, overcomes existing product defect, meets technology of transmission of electricity requirement.
Summary of the invention
Due to the critical role of glass insulator in electric power conveying, this application provides a kind of three novel umbellate form glass insulators, there is due to it particular advantages such as open type, many umbellate forms, contamination are few, easy cleaning, be therefore more suitable for the serious area of pollution flashover and use.By means such as the dimension combination in beveled structure moulding, size umbrella disk footpath, a kind of large distance three layers of umbrella toughened glass insulator are invented.
To achieve these goals, the technical scheme taked of the application is as follows:
A kind of large distance three layers of umbrella toughened glass insulator, comprise " convex " shape glass workpiece of chapeau de fer and lower opening, the head of chapeau de fer is buckled in " convex " shape glass workpiece, and both are fixed together by the first glue layer; Be hollow type screwed hole in the head of described " convex " shape glass workpiece, the root of steel pin is installed in the screwed hole of " convex " shape glass workpiece, by the second glue layer, steel pin and " convex " shape glass workpiece is fixed together; In the ball-and-socket of chapeau de fer head, be provided with locking pin-and-hole, being connected with the head of the steel pin of other a slice insulator by the locking pin in locking pin-and-hole becomes insulator string; The outside of described " convex " shape glass workpiece, is disposed with umbrella rib, middle umbrella rib and subumbrella rib from top to bottom; Described upper umbrella rib and the angle of horizontal direction are 5 ~ 10 °, and the length of upper umbrella rib 15 ~ 50mm longer than middle umbrella rib.
Preferably, described upper umbrella rib and the angle of horizontal direction are 5.5 °;
Preferably, described upper umbrella rib 21mm longer than middle umbrella rib;
Between glass workpiece and chapeau de fer, between glass workpiece and steel pin, adopt a kind of high-strength special type adhesive.Tensile strength and the product strength grade of this adhesive match.
Described steel pin root baseplane on be bonded with malthoid pad.Malthoid pad mainly plays cushioning effect, prevents locking pin overtorquing, to such an extent as to active force between glass workpiece and steel pin is excessive and cause glass workpiece broken;
The cap mouth of described chapeau de fer and the contact-making surface of " convex " shape glass workpiece are provided with plastic washer.Plastic washer plays the effect of impulsive force between buffering chapeau de fer and glass workpiece;
For three layers of beveled structure, middle umbrella stretches out and is less than umbrella and stretches out 15mm or more.Its upper and lower dish footpath difference of umbellate form replaced due to large umbellule is larger, is more conducive to extending continuous icicle formation time, plays better effect to circuit anti-ice ability.But difference larger small product size in dish footpath is larger, the corresponding increasing of production difficulty, and finished product rate reduces.Analyze through comprehensive, determine the monolateral overhang of middle umbrella rib 21mm less of upper umbrella.In addition, increase a umbellule rib in umbrella shape inside, be conducive to improving creepage distance, increase abrupt slope proof strength, product can better be located when mucilage binding.
Adopt staggered umbrella design, namely in the middle of, the umbrella footpath of umbrella is less than subumbrella, form the filthy umbrella shape formula of the similar electrical equipment external insulation of large--little--gamp, by rational umbrella inclination angle, make insulator under the prerequisite not affecting creep distance, to make on insulator not easily dust, and due to the design of large-little-gamp, pollutant is not easily fallen in the middle of umbrella rib, and causes the defect of dust stratification, thus improve the self-cleaning property of insulator.In addition, insulator head adopts socket cap design, has that volume is little, lightweight, intensity advantages of higher compared with the design of porcelain insulator conehead, and it is different filthy area under being better applicable to Different climate, and its nature (wind, rain, snow) self-cleaning ability is strong.
Glass insulator is without inner-defect, and range estimation just can identify its damaged condition, glass insulator " zero self-failure ", eliminates ultra-high-tension power transmission line " survey zero " inspection piecewise regularly, simplifies maintenance, greatly reduce maintenance cost.
In sum, the large distance that the application provides three layers of umbrella toughened glass insulator, have the advantages such as creep distance is large, self-cleaning ability strong, simplification maintenance.
