Part various electromechanical stress caused by changing and fail, otherwise will damage use and the service life of whole transmission line of electricity.
Existing insulator body is usually the hollow insulator with full skirt, and insulator upper and lower ends are connected with metab,
It is fixedly connected through plug through insulator with metab, the design structure of existing insulator is fairly simple, easy to use；But absolutely
It is inclined-plane that the full skirt shape design of edge, which generally is upper surface, and lower surface is plane, and the full skirt of this planform can only be adopted
With upright installation, if using stand upside down installation, since upward full skirt surface be plane, it is possible to cause ponding, influence exhausted
The antifouling property of edge.
The content of the invention
For the above situation, the purpose of this utility model is to provide a kind of beveled structure of pillar insulator, it is used
It is the defects of structure on inclined-plane is so as to overcome prior art insulator to be not suitable with handstand installation to set full skirt upper and lower surface, is improved
Stain resistance, overall structure is scientific and reasonable, simple and compact, using with it is easy for installation, wide market, makes easy to promote
With.
To achieve these goals, a kind of beveled structure of pillar insulator, it is cylindrical including being co-axially located at insulator
Several layers of full skirt on face, the upper and lower surface of the full skirt smoothly without rib, and the size of full skirt upper surface inclination angle theta is 10~15 °,
The size of full skirt lower surface angle of inclination beta is 8~10 °.
In order to realize structure, effect optimization, its further step is：The size of full skirt upper surface inclination angle theta is
12 °, the size of full skirt lower surface angle of inclination beta is 9 °.
Full skirt on the insulator periphery is three layers.
The outside diameter size of three layers of full skirt by being sequentially increased from top to bottom on the insulator periphery.
The utility model caused beneficial effect compared with prior art：
(I) the utility model uses and sets the several layers of smooth nothing of coaxial full skirt and upper and lower surface on insulator periphery
Rib, insulator is cleaned using smoothly facilitating without rib structure in wind and rain, reduce dust accumulation speed, is also convenient for artificial flushing cleaning, and is set
The utilization rate that several layers of full skirt are conducive to improve creepage distance is put, ensures the safe and reliable of transmission line of electricity；
(II) the utility model uses the structure that full skirt upper and lower surface is inclined-plane, when being installed using upright or handstand, umbrella
Skirt surface will not ponding, do not influence the antifouling property of insulator, creepage distance utilization rate is high, and quick and easy for installation, tool
There is higher engineer application economy；
(III) the utility model use setting full skirt upper and lower surface is the structure on inclined-plane so as to overcome the prior art to insulate
Inadaptable the defects of the installing of standing upside down of son, improves the stain resistance of insulator, reduces dust accumulation speed, can prolong the service life,
Overall structure is scientific and reasonable, simple and compact, using with it is easy for installation, there is significant economic benefit and social benefit.
The utility model is widely used in overhead transmission line and matches.
The utility model is described in further detail with reference to the accompanying drawings and examples.
