Description
Technical field
The present invention relates to parts and the manufacture method thereof of a kind of express locomotive (namely speed is at the express locomotive of more than 160km/h) pantograph, is that a kind of pantograph, bus, gap bridge cable etc. are used as insulating supporting silicon rubber compound insulator and manufacture method thereof specifically.
Background technology
Silicon rubber compound insulator mainly contains three chief components: play the silicon rubber umbrella skirt of external insulation effect, play the metal-ware that the epoxy resin fiberglass of interior insulating effect is excellent, connection function is played at two ends.External insulation silicon rubber umbrella skirt mainly plays the ability that weather-proof, hydrophobicity, migration of hydrophobicity, raising creepage distance etc. increase life of product and improve product electric property, and the insulating supporting of a rigidity and effect that is counter-bending and that reverse mainly are played in interior insulation.Just because of this, silicon rubber compound insulator makes silicon rubber compound insulator be widely used on express locomotive now with the performance advantage of its uniqueness.In express locomotive pantograph, bus, gap bridge cable, very important parts are exactly the insulator being just used as insulation and supporting; What use now mainly contains usual silicone rubber composite insulator, the overall epoxy resin insulator of some Imported, a little ceramic insulator.
Because common silicon rubber compound insulator adopts the rear integrated vulcanizing of gold utensil crimping shaping, the silicon rubber compound insulator of overall depanning is considered when full skirt designs and must be carried out segmental mandrel and the design of inclination angle, full skirt both sides, so there is overall matched moulds seam in the full skirt after shaping, simultaneously because of the design of full skirt inclination angle, thus cause the shirt rim of full skirt top thinner, easily occur tearing and tired phenomenon.Also there is product when mounted due to situation that the set bolt reason of projection causes the electric clearance of product to shorten, this is all that existing common silicon rubber compound insulator design is unwitnessed when producing, especially, on the express locomotive of more than speed per hour 160km/h, will there is the hidden danger of some safety in the defect of this kind of product.Constantly pursuing at a high speed at Modern High-Speed locomotive simultaneously, stable, safety, comfortable space proposes the particularity of use simultaneously to silicon rubber compound insulator, require that silicon rubber compound insulator is except meeting normal environment for use (air environmental pollution and dust storm, rain, snow, mist, dew etc.) pollute outside, the fatigue vibrations produced when also should be able to bear deadweight and the locomotive operation swing of pantograph or connection wire, simultaneously at process of passing through tunnel, mountain valley, coal yard, during the adverse circumstances such as acid rain, reduction in short-term or permanent destruction can not be there is in the electric property of product, so product is establishing the tensile load of clocking requirement metal-ware large, anti-torsion ability is strong, product electric property is stablized, product heat resistance is excellent, such side can ensure the safe operating life of silicon rubber compound insulator, avoid the number of times changed, reduce unnecessary loss, for this situation, common method for designing is that two ends all select the metal-ware of aluminum or hot galvanizing shaping with the inclination angle design and the crimping of general end accessory being convenient to depanning, design and production method is: first by the macromolecular material of the cementabilities such as the end hacking of epoxy resin plug or coating epoxy resin, then metal-ware is crimped on the two ends of epoxy resin plug, again epoxy resin plug is carried out to the coating oven dry of coupling agent, finally carry out injector integral injection molding, also have after first carrying out integral injection molding, finally crimp two ends metal-ware shaping, but problem is in the following areas deposited in this kind of design: (1) full skirt thinner thickness, easily torn by wind tunnel effect when tunnel and narrow mountain valley or non-recoverable deformation occurs, because of moving of full skirt, destruction is played to high-voltage-stable electric field simultaneously.(2) product adopts integrated vulcanizing shaping, and inevitable longitudinal die sinking seam, affects external insulation full skirt tearing strength, and can reduce the electric property of insulator after polluting.(3) vibrate the impact on product structure when common crimping mode can not meet express locomotive high-speed motion, cause product to there is potential safety hazard.(4) fail during design to consider actual installation situation, cause protruding bolt to directly reduce insulator electric clearance, cause insulator electric property to reduce greatly.
Visible, there is external shed bad mechanical strength in existing silicon rubber compound insulator, end accessory resists stretching displacement ability, product anti-torsion performance is low, full skirt pollutes the decline of rear product electric property outward, product design design is unreasonable, the shortcomings such as actual operating mode are not considered in product design.
