Abstract
The utility model discloses a composite insulator, which relates to the technical field of AC contact lines of electrified railroad, and particularly relates to an insulating support of AC contact lines. The utility model has the technical proposal that epoxy glass fiber is used for replacing a porcelain rod or a glass rod, a core rod is integrally injected with a silicon rubber umbrella skirt sheath, and the both ends of the core rod are connected with hardware fittings through press fitting. The weight of the composite insulator is only one third of the weight of a porcelain rod insulator or a glass rod insulator of the same grade. When an impact bending load far larger than a rated load is applied to the composite insulator, the amount of deformation of the insulator can only be enlarged temporarily. Once external force disappears, the insulator restores to the original state immediately, which is a required performance in high speed electrified railway.
Description
The utility model relates to a kind of technical field of interchange contact line of electric railway, refers to a kind of insulation support that exchanges contact line especially.
Traditional electric railway, it all is to adopt porcelain rod insulator or glass shape insulator that its insulation that exchanges contact line is supported, this insulator Heavy Weight, cracky, and all be fragile material, under the effect of macrobending impulsive force, ceramic material is easy to produce fracture damage, raising along with the speed of service of electric railway locomotive, contact line supports with insulator when locomotive is speeded, the impact load that bears is sizable, and therefore, the demand that the insulator of porcelain or glass bar type will adapt to high-speed electric railway is quite difficult.
The purpose of this utility model is to provide a kind of synthetic insulator.
The utility model is achieved by the following technical solution: replace porcelain rod or glass bar with the epoxy resin fiberglass plug, general injection silicon rubber umbrella sheath press-fits the connection gold utensil at its two ends then on plug.
The synthetic insulator that the utility model is made, its weight only is 1/3rd of ad eundem porcelain or glass bar insulator weight, when the impact bending load that is far longer than rated load applies on it moment, only can temporarily increase the insulator bending deformation quantity, external force is in case disappear, recovering original state at once again, is the performance that high-speed electric railway extremely needs.
Accompanying drawing is product structure figure of the present utility model
Be described in further detail below in conjunction with accompanying drawing:
Wherein: 1-gold utensil, 2-silicon rubber umbrella sheath, 3-epoxy resin fiberglass plug, 4-sealing circle
2 injections of silicon rubber umbrella sheath are wrapped in the surface of epoxy resin fiberglass plug 3, gold utensil 1 is pressed into and is socketed on the epoxy resin fiberglass plug 3, sealing circle 4 is enclosed within on the silicon rubber umbrella sheath 2, and the endoporus that gold utensil 1 is inserted by epoxy resin fiberglass plug 3 is than the little 0.3-0.5mm of epoxy resin fiberglass plug 3 external diameters.
When using the utility model, because of replacing porcelain rod or glass bar with epoxy resin fiberglass plug 3, when the impact bending load that is far longer than rated load applies on it moment, only can temporarily increase bending deformation quantity of the present utility model, external force is in case disappear, restoring to the original state again at once, is the performance that high-speed electric railway extremely needs.
