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 null value is from broken double -deck 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 zero self-failure double-layer 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.
The insulator that transmission line uses is once breakdownly will lose insulation property (being commonly called as " null value "), in order to ensure that the safe operation of transmission line should be changed the insulator lost efficacy in time, the insulator how quick and precisely telling inefficacy is one of transmission line maintenance work difficult problem, and toughened glass insulator has " zero self-failure " feature can find inefficacy insulator by range estimation, this is that insulator that is ceramic and other materials does not possess.
For these reasons, design invention is a kind of just can seem particularly necessary in null value from broken insulator.
Summary of the invention
Due to the critical role of glass insulator in electric power conveying, this application provides a kind of novel many umbellate forms glass insulator, 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, invent a kind of zero self-failure double-layer umbrella toughened glass insulator.
To achieve these goals, the technical scheme taked of the application is as follows:
A kind of zero self-failure double-layer umbrella toughened glass insulator, comprises " 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 is 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; The head of steel pin is positioned at " convex " shape glass workpiece hollow type bottom; 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; In the outside of " convex " shape glass workpiece, be disposed with umbrella rib and subumbrella rib from top to bottom, the size of its umbrella rib and profile constitutes " creepage distance " size of product standard regulation, is enclosed with diaphragm at the outer surface of " convex " shape glass workpiece.
Described upper umbrella rib and the angle of horizontal direction are 5.5 °.
The root baseplane of described steel pin is bonded with malthoid pad, and malthoid pad, plays cushioning effect.
The cap mouth of described chapeau de fer and the contact-making surface of " convex " shape glass workpiece are provided with plastic washer.Be provided with plastic washer, play the effect of impulsive force between buffering chapeau de fer and glass workpiece.
The thickness of described diaphragm is 1 ~ 2mm.
Described diaphragm, have selected macromolecular material, due to glass workpiece under field conditions (factors); experience is exposed to wind and rain and is being stood under ultraviolet irradiation for a long time; the molecule of glass workpiece inside can be made to change, finally cause its decreasing insulating, reduce the useful life of glass workpiece.And the glass workpiece surface protection film arranged, ultraviolet can be absorbed, glass workpiece is played a protective role.And polymeric pressure sense film selected by diaphragm; when glass workpiece is breakdown burst time, will form certain pressure to diaphragm, diaphragm can break under pressure; make the glass workpiece burst effectively can depart from power transmission line, therefore can not threaten to transmission of electricity safety.Diaphragm can select phenolic resins class, this family macromolecule, its poor toughness, and after film forming, brittleness is higher, once pressurized can rupture.
The thickness of described diaphragm is 1 ~ 2mm, and its protective effect too thin is more weak, and too thick, not easily breaks again under pressure, makes glass workpiece effectively cannot depart from circuit.
Described upper umbrella rib and the angle of horizontal direction are 5.5 °.
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.
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 zero self-failure double-layer umbrella toughened glass insulator that the application provides, has the advantages such as self-cleaning ability is strong, simplification maintenance.
