Abstract
The utility model relates to electrification railway contact net key components and parts technical field, especially relates to the anti-bird pest composite insulator of a kind of electrification railway contact net clavate pillar.Be characterized in comprising glass fibre leading-drawing rod, described glass fibre leading-drawing rod one end is provided with double fastener hoop gold utensil, double fastener hoop gold utensil is bonded with enlarged umbrella skirt, the glass fibre leading-drawing rod other end is provided with supporting single lug gold utensil, in the middle part of described glass fibre leading-drawing rod, peripheral bond has silicone rubber jacket, silicone rubber jacket is fixed with large full skirt and little full skirt.Its enlarged umbrella skirt and large air line distance between full skirt and little full skirt strengthen, gradient increases, instantaneously when the material used when birds are nested is placed between full skirt to come off, Bird's Nest can not be formed, the coefficient of safety that circuit is run significantly increases, the power-off trip accident that can effectively prevent circuit from causing because of Bird's Nest, and the creepage distance of insulator can be increased, increase the antifouling radius of insulator.
Description
Technical field
The utility model relates to electrification railway contact net key components and parts technical field, especially relates to the anti-bird pest composite insulator of a kind of electrification railway contact net clavate pillar.
Background technology
The clavate post composite insulators of prior art comprises gold utensil, silicon rubber size full skirt, silicone rubber jacket and glass fibre leading-drawing rod, wherein gold utensil is crimped on the two ends of glass fibre leading-drawing rod, leading-drawing rod outer setting has silicone rubber jacket, a large full skirt of silicon rubber and two little full skirts of silicon rubber are one group, evenly distributed successively on sheath have full skirt group, large full skirt diameter is consistent, and little full skirt diameter is consistent.In use running, because the air line distance between large full skirt and little full skirt is too small, too straight, birds are nested on full skirt relatively easily simple, after birds are nested, Bird's Nest can constantly increase, when causing insulator dielectric apart from time inadequate, line discharge can be caused to trip, affect security of operation.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of electrification railway contact net clavate pillar anti-bird pest composite insulator, thus effectively solves the defect existed in prior art.
For achieving the above object, the technical scheme that the utility model is taked is: the described anti-bird pest composite insulator of electrification railway contact net clavate pillar, be characterized in comprising glass fibre leading-drawing rod, described glass fibre leading-drawing rod one end is provided with double fastener hoop gold utensil, double fastener hoop gold utensil is bonded with enlarged umbrella skirt, the glass fibre leading-drawing rod other end is provided with supporting single lug gold utensil, in the middle part of described glass fibre leading-drawing rod, peripheral bond has silicone rubber jacket, silicone rubber jacket is fixed with large full skirt and little full skirt.
Described double fastener hoop gold utensil and supporting single lug gold utensil adopt crimping mode to be fixed on the two ends of glass fibre leading-drawing rod.
Described large full skirt and little full skirt are set to multiple, and a large full skirt and two little full skirts interlock and evenly arrange on glass fibre leading-drawing rod.
The beneficial effects of the utility model are: the described anti-bird pest composite insulator of electrification railway contact net clavate pillar, it is bonded with the silicon rubber umbrella skirt of increasing at double fastener hoop gold utensil end, enlarged umbrella skirt and large air line distance between full skirt and little full skirt are strengthened, gradient increases, instantaneously when the material used when birds are nested is placed between full skirt to come off, Bird's Nest can not be formed, the coefficient of safety that circuit is run significantly increases, the power-off trip accident that can effectively prevent circuit from causing because of Bird's Nest, and the creepage distance of insulator can be increased, increase the antifouling radius of insulator.
