Abstract
The utility model discloses a kind of strain insulator, comprise gold utensil and insulator string; Described gold utensil surface adopts hot galvanizing process, any surface finish; Gold utensil is two orthogonal and iron hoops adopting splayed to rivet, and gold utensil is positioned at the two ends of insulator string, and all half stretches out insulator string outside, and insulator string is provided with three shirt rims, road, and insulator string outer application has insulating barrier.Insulator string described in the utility model adopts advanced composite material (ACM) to make, and has good corrosion resistance and ageing resistance.Insulator string adopts the antifouling design of three shirt rims, road, adds creepage distance, prevents pollution flashover phenomenon from occurring.When insulating barrier occurs that overload also can ensure the continuity of bracing wire time damaged, pole collapse accident can not be there is.The utility model volume is little, lightweight, and not cracky, easy for installation, both can match with wedge clamp, reinforcing bar chuck and preformed armor rods also can be used to fix.
Description
Technical field
The utility model relates to field of power transmission, specifically a kind of strain insulator.
Background technology
Insulator is a kind of special insulation control, can play an important role in overhead transmission line.In one's early years, insulator is used for electric pole, and slowly develop and hung the insulator of a lot of plate-like in one end of high type high-tension bus-bar connection tower, it is made up of glass or pottery usually in order to increase creepage distance.Insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.Existing insulator allows pulling force less, and corrosion resistance and ageing resistance are all undesirable, and volume is comparatively large, heavier-weight.
Utility model content
The purpose of this utility model is to provide a kind of strain insulator, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of strain insulator, comprises gold utensil and insulator string; Described gold utensil surface adopts hot galvanizing process, any surface finish; Gold utensil is two orthogonal and iron hoops adopting splayed to rivet, and gold utensil is positioned at the two ends of insulator string, and all half stretches out insulator string outside, and insulator string is provided with three shirt rims, road, and insulator string outer application has insulating barrier.
As further program of the utility model: the maximum permission pulling force of gold utensil described in the utility model is 90KN; The highest withstand voltage of described insulator string is 42KV.
Compared with prior art, the beneficial effects of the utility model are: adopt splayed to rivet between two gold utensils described in the utility model, better than welding effect, exceeding in the use procedure destroying pulling force, or meet accident phenomenon time, two closed iron hoops are interconnected, prevent the generation of pole collapse accident, make whole accident range shorter to minimum influence face, for the safe operation of electrical network provides safeguard.Described insulator string adopts advanced composite material (ACM) to make, and largely improves dynamo-electric permission pulling force, improves withstand voltage level, have good corrosion resistance and ageing resistance.Insulator string adopts the antifouling design of three shirt rims, road, adds creepage distance, prevents pollution flashover phenomenon from occurring.When insulating barrier occurs that overload also can ensure the continuity of bracing wire time damaged, pole collapse accident can not be there is.The utility model volume is little, lightweight, and not cracky, easy for installation, both can match with wedge clamp, reinforcing bar chuck and preformed armor rods also can be used to fix.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-gold utensil, 2-insulator string.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of strain insulator, comprises gold utensil 1 and insulator string 2; Described gold utensil 1 surface adopts hot galvanizing process, any surface finish; Gold utensil 1 is two orthogonal and iron hoops adopting splayed to rivet, and gold utensil 1 is positioned at the two ends of insulator string 2, and all half to stretch out insulator string 2 outside, insulator string 2 is provided with three shirt rims, road, and insulator string 2 outer application has insulating barrier.
Further, the maximum permission pulling force of gold utensil 1 described in the utility model is 90KN; The highest withstand voltage of described insulator string 2 is 42KV.
Splayed is adopted to rivet between the utility model two gold utensils 1, better than welding effect, exceeding in the use procedure destroying pulling force, or meet accident phenomenon time, two closed iron hoops are interconnected, prevent the generation of pole collapse accident, make whole accident range shorter to minimum influence face, for the safe operation of electrical network provides safeguard
Insulator string described in the utility model adopts advanced composite material (ACM) to make, and largely improves dynamo-electric permission pulling force, improves withstand voltage level, have good corrosion resistance and ageing resistance.
The utility model insulating barrier occurs that overload also can ensure the continuity of bracing wire time damaged, pole collapse accident can not occur.
Insulator string 2 described in the utility model adopts the antifouling design of three shirt rims, road, adds creepage distance, prevents pollution flashover phenomenon from occurring.
The utility model volume is little, lightweight, and not cracky, easy for installation, both can match with wedge clamp, reinforcing bar chuck and preformed armor rods also can be used to fix.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
