Abstract
The utility model discloses a kind of electrification railway contact net bracket porcelain composite insulator, including socket type metal-ware, porcelain core rod, silica gel umbrella cover and monaural type metal-ware；Wherein socket type metal-ware and monaural type metal-ware are individually fixed in the both ends of the porcelain core rod；Silica gel umbrella cover is wrapped in the outside of porcelain core rod；Porcelain core rod is the hollow obturator full of drying nitrogen；Silica gel umbrella cover includes big full skirt, small full skirt and anti-bird full skirt, and the anti-bird full skirt is located at monaural type metal-ware side；One big full skirt and two small full skirts are a full skirt group, and the umbrella cover includes some full skirt groups.Socket type metal-ware and monaural the type metal-ware is aluminum alloy materials.The utility model possesses the advantages of bending resistance is stronger, weight is lighter, insulating properties are more preferable compared with general porcelain composite insulator, and can prevent birds nest between insulator and pillar, and external insulation intensity is high, has good stain resistance.
Description
Technical field
The utility model belongs to electrification railway contact net bracket accessories technical field, more particularly to a kind of electric railway
Contact network cantilever porcelain composite insulator.
Background technology
The bracket insulator that electrification railway contact net largely uses at present has porcelain rod insulator and silicon rubber compound absolutely
Edge.Porcelain rod insulator bending resistance it is antitorque it is good, mechanical performance is excellent, silicon rubber compound insulator electric property is remarkable, Liang Zheyi
A large amount of use are that railway system's safe operation and economic society fast development are made that in electrification railway contact net electric power system
Tremendous contribution.
But operating porcelain rod insulator surface easily adheres to filth, weather conditions are likely to occur outside sudden strain of a muscle when changing
Network, and heavier, carrying and installation relative difficulty.The long-term creep and a small number of brittle failures of silicon rubber compound insulator interior insulation plug
Accident may be induced with end part seal failure.On the other hand, with the recovery of the Along Railway ecosystem, there are birds exhausted
The situation of nest between edge and pillar, repeatedly cause insulator short-circuit, railway operation maintenance department was needed in the avian reproduction phase
Between spend a large amount of manpower and materials to remove bird's nests.
In recent years, there are some porcelain composite wrist-arm insulators in Railway Market, but existing product has quality big, profile
Size is big, bending resistance is insufficient and the shortcomings that anti-bird performance deficiency.
The content of the invention
In view of this, the purpose of this utility model be to provide it is a kind of it is compact-sized, globality is strong, possess good resistant energy
Power, and in light weight, small volume, external insulation intensity are good, high mechanical strength, without periodically cleaning, prevent the performance of birds nest
Excellent electrification railway contact net bracket insulator.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：A kind of electric railway is provided to connect
Net-fault bracket porcelain composite insulator, including socket type metal-ware 1, porcelain core rod 2, silica gel umbrella cover 3 and monaural type metal-ware
4；Socket type metal-ware 1 and monaural the type metal-ware 4 is individually fixed in the both ends of the porcelain core rod 2, and silica gel umbrella cover 3 wraps
It is wrapped in the outside of porcelain core rod 2；The porcelain core rod 2 is the hollow obturator full of drying nitrogen；Silica gel umbrella cover 3 include big full skirt 3-1,
Small full skirt 3-2 and anti-bird full skirt 3-3, the anti-bird full skirt 3-3 are located at the side of monaural type metal-ware 4.
Further, a big full skirt 3-1 and full skirt 3-2 two small is a full skirt group, if the silica gel umbrella cover 3 includes
Dry full skirt group.
Further, socket type metal-ware 1, monaural type metal-ware 4 and the junction of porcelain core rod 2 are pyramidal structure 5.
Further, socket type metal-ware 1 and monaural the type metal-ware 4 uses aluminum alloy materials.
Further, inorganic silicic acid is used between the socket type metal-ware 1, monaural type metal-ware 4 and porcelain core rod 2
Salt adhesive is fixedly connected.
Relative to prior art, the utility model has the advantage that：
(1) the resistance to pollution performance of the utility model, self-cleaning property are good.Surface filth is accumulated in big full skirt mostly, silica gel category
It is higher in lyophobic dust, surface flatness so that filth can realize self-cleaning function by driving rain.
(2) the utility model porcelain core rod is non-aging, service life length.
(3) the utility model uses the hollow porcelain core rod full of drying nitrogen, increase effectively porcelain core rod the moment of inertia, improves
The bending strength of insulator, and alleviate the weight of insulator.
(4) the utility model end uses the anti-bird full skirt of big external diameter, can prevent birds nest.
Brief description of the drawings
Fig. 1 is a kind of structural representation of electrification railway contact net bracket porcelain composite insulator described in the utility model
Figure.
Wherein, 1. socket type metal-ware, 2. porcelain core rods, 3. silica gel umbrella covers, 3-1. big full skirts, the small full skirts of 3-2., 3-3.
Anti- bird full skirt, 4. monaural type metal-wares, 5. pyramidal structures.
Embodiment
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, the utility model includes socket type metal-ware 1, porcelain core rod 2, silica gel umbrella cover 3 and monaural type metal
Annex 4；Socket type metal-ware 1 and monaural the type metal-ware 4 is individually fixed in the both ends of the porcelain core rod 2, silica gel umbrella
Set 3 is wrapped in the outside of porcelain core rod 2；The porcelain core rod 2 is the hollow obturator full of drying nitrogen；Silica gel umbrella cover 3 includes gamp
Skirt 3-1, small full skirt 3-2 and anti-bird full skirt 3-3, the anti-bird full skirt 3-3 are located at the side of monaural type metal-ware 4.One gamp
Skirt 3-1 and full skirt 3-2 two small is a full skirt group, and the silica gel umbrella cover 3 includes some full skirt groups.Socket type metal-ware 1,
