Abstract
The utility model discloses a composite insulator, which comprises a hardware connected with both ends, a middle insulating mandrel, a silicone rubber shield and an outside large sheds; wherein, the first piece and certain middle pieces of sheds of the silicone rubber shield are outside umbrellas; four prismatic and protuberant reinforcements which are extended from the center to the four directions respectively are arranged on the umbrella. The utility model has the advantages of high strength, low deformation, saving in material and being applicable to heavy flurry area, compared with the prior art.
Description
Technical field
Utility model relates to a kind of especially big umbrella composite insulator, belong to insulator field in the electric power system power transmission and transformation line, this composite insulator is specially adapted to bear the mechanical connection and the electric insulation work of lead and gold utensil and iron tower in the power circuit in the ice and snow environment.
Background technology
Insulator has a variety ofly in the existing power circuit, and wherein the full skirt of composite insulator design also has and adopts first full skirt to strengthen design in order to prevent bird pest and accumulated snow ice slush from forming insulator arc-over.Because silastic material is soft, when especially big umbrella under the thicker situation of accumulated snow easily downwards carbuncle draw distortion, weakened its protective action to following full skirt, cause insulator arc-over easily.
Summary of the invention
The utility model provides a kind of especially big umbrella of yielding composite insulator of not allowing.
For achieving the above object, the structure of especially big umbrella composite insulator of the present invention is: comprise that mainly intermediate insulation plug, umbrella cover and two ends are connected gold utensil, first of this umbrella cover or a few full skirts are especially big umbrella, are provided with four or the more therefrom reinforcement of the extraradial rib shape of mind-set projection on described especially big umbrella.
Described reinforcement bottom links to each other with full skirt, and side entad links to each other with the umbrella cover of mandrel outer.
The umbrella of described especially big umbrella is directly big more than 30% than the umbrella footpath of other full skirt.
From above-mentioned improvement as can be known, compared with the prior art the technical program has following advantage:
1, the especially big umbrella of band reinforcement of the present invention, by on gamp, being provided with four therefrom reinforcements of the rib shape projection of mind-set four direction radiation, this reinforcement bottom links to each other with full skirt, side entad links to each other with the umbrella cover of mandrel outer, the effect of distortion downwards when preventing that full skirt is stressed by oblique pull-up.
2,, the landing of accumulated snow will be promoted because the accumulated snow on the full skirt of reinforcement has the effect of cutting apart.
3, especially big umbrella intensity height, distortion little, applicable in the bigger environment of wind and snow.
4, simple in structure, convenient for production, saving material.
Description of drawings
Fig. 1 is the vertical outward appearance and the cross-sectional schematic of especially big umbrella composite insulator one preferred embodiment of the utility model;
Fig. 2 is to the schematic views that forms by the B of Fig. 1.
Fig. 3 amplifies cut-away view by the A of Fig. 2 to the part that forms.
Embodiment
Now the preferred embodiment shown in conjunction with the accompanying drawings is further described the especially big umbrella composite insulator of the utility model.
As shown in Figure 1, the especially big umbrella composite insulator of the utility model is made up of upper end gold utensil 1, lower end gold utensil 2, plug 3, reinforcement 4, especially big umbrella 5, common umbellule 6, common gamp 7.During installation insulator upper end gold utensil being hung over the iron tower end connects on the gold utensil, lead and relevant connection gold utensil are hung on the gold utensil of insulator lower end, meet heavy snow weather during the circuit operation, especially big umbrella will shelter from that the full skirt in the certain limit keeps dry it and the good insulation performance performance below it, when ice dissolution, will flow down, and avoid being connected in series with following full skirt along the especially big umbrella outside.Can prevent also that at ordinary times birds droppings from falling on the following full skirt.And, avoided the blocked up especially big umbrella that causes of accumulated snow to droop distortion owing to designed four therefrom extraradial reinforcements of mind-set.
As shown in Figure 2, the especially big umbrella composite insulator of the utility model mainly is first or several full skirts are arranged is especially big umbrella, its umbrella footpath is bigger more than 30% than the umbrella footpath of other full skirt usually, this especially big umbrella is provided with four therefrom reinforcements of the rib shape projection of four direction homogeneous radiation around the mind-set, this reinforcement bottom links to each other with full skirt, side entad links to each other with the umbrella cover of mandrel outer, the effect of distortion downwards when preventing that full skirt is stressed by oblique pull-up.These four reinforcements design land area and the die sinking draw direction when the compression molding of insulator umbrella cover respectively, therefore have feasibility and simplification on technology.The height of its reinforcement and gradient can be according to diameter and the environmental requirement design and the adjustment (as shown in Figure 3) of especially big umbrella.
As mentioned above as can be known, the especially big umbrella composite insulator of the utility model with said structure characteristics, especially big umbrella intensity height, the distortion little, following full skirt is protected, and the insulation property of product and weather-resistant property become more good, simple in structure and attractive in appearance, and save materials, be particularly suitable for the bigger area of wind and snow.
The especially big umbrella composite insulator of the utility model only illustrates some preferred embodiments in this manual, is not to its restriction.This professional and technical personnel can structurally make various variations or modification according to the present utility model design and spirit, for example can design a plurality ofly to have by the especially big full skirt of said structure feature or the quantity of increase reinforcement etc. on same insulator.Therefore these must belong to protection range of the present utility model.
Claims (3)
