Abstract
A silicone rubber composite insulator for a high-voltage power transmission line comprises an FRP insulating tube. The upper and lower ends of the FRP insulating tube are sealed. A metal horizontal bar is fixed on the upper end of the FRP insulating tube by crimping. The two ends of the metal horizontal bar extend out of the FRP insulating tube, thereby being beneficial for connecting with an upper part suspension member. A metal horizontal pipe is fixed on the lower end of the FRP insulating tube by crimping. The metal horizontal pipe has a length equal to the diameter of the FRP insulating tube, thereby being beneficial for silicone rubber umbrella skirts to sleeve the FRP insulating tube from the lower part and connect with a lower part suspension member. The middle part of the FRP insulating tube is provided with the multiple silicone rubber umbrella skirts, and the external diameter of each of the places having the silicone rubber umbrella skirts on the FRP insulating tube is smaller than that of each of the places having no silicone rubber umbrella skirt by 1-3 mm. The outer diameters of the silicone rubber umbrella skirts are of a large type and a small type which are differed from each other by 3-5 cm, and every two adjacent silicone rubber umbrella skirts are of different diameter types. The silicone rubber composite insulator has a high strength and the silicone rubber umbrella skirts are firmly fixed; and every two adjacent silicone rubber umbrella skirts are of different diameter types so that the adjacent upper and lower umbrella skirts are prevented from linking into a chain by rain water easily during heavy or torrent rain and causing rain flashover.
Description
Technical field
The utensil that relates to ultra-high-tension power transmission line of the present utility model, i.e. a kind of ultra-high-tension power transmission line silicon rubber compound insulator.
Technical background
In transmission line, the Main Function of insulator is mechanically interconnected high voltage electricity transmission conductive wire and overhead line structures, simultaneously mutually insulated on electric.A large amount of uses is porcelain and glass insulator at present, it is the main measurement factor that determines whether operating insulator can well move for a long time that anti-soil dodges performance, but insulator unavoidably will be subject to the pollution of filthy, the naturally saline and alkaline and dust of industry etc. in running, these filthy material resistance under drying regime that are attached to insulator surface are usually very large, can the normal operation of insulator do not exerted an influence.When atmospheric humidity is higher, particularly at mist, dew, drizzle etc. under severe meteorological condition, filth will be by moistening, causes that insulator surface resistance reduces, leakage current increases, thereby causes the pollution flashover voltage of insulator significantly to reduce.In recent years the silica gel composite insulator of bringing into use is mainly used in transformer station, there is good hydrophobicity, ageing resistance, proof tracking and electrical erosion resistance, there is very high tensile strength and bending strength, its mechanical strength is high, shock resistance, shockproof and anti-brittle failure performance are good, lightweight, convenient for installation and maintenance, for ultra-high-tension power transmission line, following three problems are arranged: 1, the connection of upper and lower gold utensil and FRP insulated tube is lower with the screw rod bonding strength; 2, the silicon rubber full skirt is thin, yielding; 3, between upper and lower full skirt easily under heavy rain or heavy rain rainwater be linked to be chain, cause that rain dodges.
Summary of the invention
For the connection that overcomes the upper and lower gold utensil of silica gel composite insulator and FRP insulated tube is lower with the screw rod bonding strength, between the thin yielding and upper and lower full skirt of silicon rubber full skirt easily under heavy rain or heavy rain rainwater be linked to be chain, cause the shortcoming that rain dodges, the utility model proposes the new design of a kind of ultra-high-tension power transmission line with silicon rubber compound insulator.
This ultra-high-tension power transmission line silicon rubber compound insulator, comprise the FRP(fibre-reinforced plastics, be commonly called as fiberglass) insulated tube, FRP insulated tube upper-lower seal, it is characterized in that, upper end at the FRP insulated tube is fixed with the metal horizontal bar by crimping, stretch out outside the FRP insulated tube at the two ends of metal horizontal bar, be convenient to be connected with the upper suspension part, lower end at the FRP insulated tube is fixed with the metal transverse tube by crimping, the length of metal transverse tube equals the diameter of FRP insulated tube, being convenient to the silicon rubber full skirt is inserted in from bottom and is connected with the bottom suspender, the middle part of FRP insulated tube is equipped with several silicon rubber full skirts, its external diameter of silicon rubber full skirt place is installed than the little 1-3mm in silicon rubber full skirt place is not installed at the FRP insulated tube.
The part of metal horizontal bar middle part in the FRP insulated tube is flakes six aciculiforms.
The part of metal transverse tube in the FRP insulated tube is flakes six aciculiforms.
Silicon rubber full skirt outer surface is a truncated cone-shaped, and there is a cylindrical hole at center, and the external diameter that the internal diameter of cylindrical hole and FRP insulated tube are installed silicon rubber full skirt place is equal, and silicon rubber full skirt bottom is sealed by annulus.
The external diameter of silicon rubber full skirt has two kinds of sizes, differs 3-5cm, and the size of each silicon rubber full skirt staggers mutually up and down.
On the FRP insulated tube, between each silicon rubber full skirt, silicone rubber jacket is arranged.
The upper and lower metalwork of the utility model adopts crimping to make, outer closure in the silicon rubber full skirt, and intensity is high, and silicon rubber full skirt and silicone rubber jacket have certain elasticity, from bottom, are inserted in successively, are arranged on the slightly little place of FRP insulated tube top external diameter, can be fixed; The size of each silicon rubber full skirt staggers mutually up and down, has avoided between adjacent upper and lower full skirt easily rainwater under heavy rain or heavy rain to be linked to be chain, causes the possibility that rain dodges.The utility model adopts the composite materials such as FRP insulated tube and silicon rubber full skirt, with traditional porcelain, with glass insulator, compare, there is good resistant sudden strain of a muscle property and anti-galvanic corrosion ability, excellent anti-ozone aging, heat ageing, ultraviolet light and aging and atmospheric aging performance and higher thermal endurance and good cold resistance.There is good hydrophobicity and migration of hydrophobicity.
