Abstract
The utility model relates to a sealed insulating rod for a section insulator of an electric railway contact net. The utility model is characterized in that an insulating rod which is coated with an outer coating layer is coated out of an insulating basic body core rod; the core rod is made of the modified epoxy solidifying system and the glass fiber in a match mode; the outer coating layer is made of the polyester plastic. The sealed insulating rod has simple structure, light weight and convenient installation and maintenance. The utility model provides a novel sealed insulating rod for the reliable power supply and the safe transportation for the electric railway contact net.
Description
The utility model belongs to the power lead of elec. vehicle and along the equipment of track, specifically contact nets in electrified railways section insulator sealed insulation rod also can be described as insulation slideway, insulated tension pole.
The sealed insulation rod is the major insulation body of contact nets in electrified railways section insulator, at present China's contact system section insulator mainly adopts two kinds of epoxy resins insulation rod or high alumina ceramic insulation rods with insulation rod, owing to have certain shortcoming on its structure and the material, often produce dielectric surface flashover and internal breakdown accident, according to the power supply department incomplete statistics, the number of packages that produces the tripping operation accident because of insulation rod is of poor quality accounts for 10% of total tripping operation accident number of packages, the power supply of serious threat electric locomotive and traffic safety, the sealed insulation rod of Japan burns out easily, Switzerland uses polytetrafluoroethylene, corona resistance is bad, and its insulating power all can not satisfy domestic operating needs.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of have excellent electric insulating, arc resistance and higher draw tensile strength and bending strength, be fit to the sealed insulation rod that China's electrified railway is used.
The purpose of this utility model can reach by following measure:
The contact nets in electrified railways section insulator is the modified epoxy curing system with the plug of sealed insulation rod, the outside of plug is coated with outer covering layer, the edges at two ends place of insulation rod can have or not open the hole, the quantity of through hole is generally 1～5, plug is to be resin matrix with the modified epoxy curing system, glass fibre is the glass-felt plastic with high tensile and bending strength that reinforcing material is made, and the outer covering layer material that the outside coats adopts high-wearing feature and the good ester plastic of insulating power.
Accompanying drawing and description of drawings:
Fig. 1 is a sealed insulation bar structure scheme drawing.
Fig. 2 is that sealed insulation rod A-A is to section-drawing.
Among the figure: 1-plug, 2-outer covering layer, 3-connecting bore.
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Cross-sectional plane is that the prolate insulating body plug 1 of rectangle is coated with outer covering layer 2, and insulation rod edges at two ends place respectively has 2 through holes 3.
During making, formulation of epoxy body at first, promptly in modified epoxy, add modified firming agent, be dissolved in the acetone soln, on wrapping machine, make impregnated fabric, hang shop layer after 24 hours, on press, be heating and curing then and be pressed into sheet material, take out sheet material after being chilled to room temperature, be cut into the glass steel bar of certain width, make plug, hot-forming in die cavity with the ester plastic core rod again is the sealed insulation rod.
The utility model compared with prior art has following advantage:
1, use sealed insulating rod for section insulator of electric railway contact net after, electric locomotive operates steadily, no trip accident generation, every mechanical property and electric property are good, also applicable to the quasi high-speed operation of electric locomotive.
2, the utility model is simple, and is in light weight, and installation and maintenance and manufacturing are all very convenient, are suitable for suitability for industrialized production and promote the use of.
