Abstract
The utility model relates to a semi-coated type disc form porcelain/glass composite umbrella skirt insulator used for an electric transmission line, and relates to a strain insulator-string used for the electric transmission line, which belongs to the power equipment technical field. The umbrella skirt insulator is composed of a steel cap, a porcelain insulator, a silicone rubber composite umbrella skirt and a steel foot. The creepage distance of the hydrophobicity is increased, so that the problem that porcelain and glass insulators are frangible can be solved. The umbrella spacing of the porcelain and glass insulators can be improved, the electrocorrosion of high electrical-field area at the end part of the porcelain and glass insulators on the composite material, a steel angle and the steel cap can be avoided, and the lightning protection performance can be enhanced. A dry area is effectively added, and wet voltage-tolerance level is enhanced. The problems of easy shedding and short usage life of the RTV paint on the tension resistant porcelain (glass) insulator can be solved, and the construction hidden trouble can be avoided.

Background technology
Characteristics such as composite insulator is in light weight with it, the wet voltage of resistant is high, non-maintaining were popularized in electrical network rapidly from about 1997.Yet the insulator of other types (porcelain, glass insulator etc.) coexists as in the same line road, can not solve thoroughly that circuit exempts to clean and the problem of pollution flashover.At present spraying RTV or PRTV of adopting, useful life is short, can not tackle the problem at its root more.The professor of China DianKeYuan expert, Tsing-Hua University and other many universities and colleges has dropped into a large amount of research.Experimental study in 2012 is proof just, organically combines through porcelain, glass insulator and compound full skirt, can the two advantages be got up, and can thoroughly solve circuit cleaning problem, and the resistant lightning is pressed and improved more than 2 times.Therefore, adopt the compound full skirt insulator of half clad type dish type porcelain (glass) that the safe operation of electrical network is had great significance.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of used for transmission line strain insulator-string to use insulator.
The compound full skirt insulator of a kind of used for transmission line half clad type dish type porcelain/glass of the utility model is made up of steel cap, porcelain or glass insulator, the compound full skirt of silicon rubber, steel pin.The steel cap is positioned at porcelain or glass insulator central upper; The compound full skirt of silicon rubber closely is sleeved on porcelain or the glass insulator full skirt; The compound full skirt of silicon rubber edge exceeds porcelain or glass insulator full skirt 10-30 mm; Effective hydrophobicity creep distance that the compound full skirt of silicon rubber forms is 200-420mm, accounts for the 40%-90% of former porcelain or glass insulator creep distance, and the steel pin is positioned at the below of porcelain or glass insulation subcenter.Porcelain or glass insulator are formed through the good bonding agent of high strength insulation property.Its compound full skirt is to adopt the silicon rubber gross rubber of high-quality through HTHP sulfidization molding in mould; Middle porcelain or glass insulator are that employing operating experience is abundant, the product of reliable product quality.The compound full skirt of silicon rubber closely is sleeved on porcelain or the glass insulator full skirt, and the compound full skirt of silicon rubber edge exceeds porcelain or glass insulator full skirt 10-30 mm, has increased the insulator creep distance.Effective hydrophobicity creep distance that the compound full skirt of silicon rubber forms is 200-420mm, accounts for the 40%-90% of former porcelain or glass insulator creep distance.Effectively having improved porcelain or glass insulator resistant lightning presses.Concrete making step cleans its surface at first using the compound full skirt of mould mold pressing silicon rubber then; Again porcelain (glass) insulator full skirt is cleaned, park and dry.Then bonding agent evenly is applied to the compound full skirt inner chamber of silicon rubber, the compound full skirt cover of silicon rubber is installed to solidify setting on porcelain (glass) the insulator full skirt.
The utility model characteristics:
1, increases the creepage distance of hydrophobicity, accounted for the 40%-90% of total creepage distance, improved antifouling property, exempted from cleaning, non-maintaining.
2, porcelain, the frangible difficult problem of glass insulator have been solved.
3, strengthened the umbrella spacing, improved the umbrella spacing of porcelain, glass insulator, improved that rainproof sudden strain of a muscle, ice are dodged, mist dodges, the pollution flashover performance.
4, avoided the galvano-cautery of porcelain, the high electric field region in glass insulator end, improved anti-thunder performance composite material, steel angle, steel cap.
5, the full skirt design has the edge of dripping, and under the state of drenching with rain, has increased dried district effectively, has improved the wet withstand voltage level.
6, adopt high temperature silicon vulcanization of rubber silicon rubber full skirt, solved the problem that on strain insulator porcelain (glass) insulator brush RTV coating is prone to come off, useful life is short, stopped construction safety hidden danger.
Beneficial effect: the compound full skirt insulator of a kind of used for transmission line half clad type dish type porcelain (glass) of the utility model, increased the creepage distance of hydrophobicity, improved antifouling property, exempt from cleaning, non-maintaining.Porcelain, the frangible difficult problem of glass insulator have been solved.Improved the umbrella spacing of porcelain, glass insulator, improved that rainproof sudden strain of a muscle, ice are dodged, mist dodges, the pollution flashover performance.Avoided the galvano-cautery of porcelain, the high electric field region in glass insulator end, improved anti-thunder performance composite material, steel angle, steel cap.Increase dried district effectively, improved the wet withstand voltage level.Solve on strain insulator porcelain (glass) insulator the problem that brush RTV coating is prone to come off, useful life is short, stopped construction safety hidden danger.
