Abstract
The utility model provides a solid-sealing pole rod, which comprises a solid-sealing pole rod insulator, a vacuum arc extinguish chamber and a vacuum arc extinguish chamber moving conducting rod, wherein a vacuum arc extinguish chamber guide sleeve of which the cross section has a non-circular outline is arranged on the vacuum arc extinguish chamber moving conducting rod; the vacuum arc extinguish chamber is embedded in the solid-sealing pole rod insulator; the solid-sealing pole rod insulator is provided with a guide hole used for mounting the vacuum arc extinguish chamber guide sleeve and formed at a moving end of the vacuum arc extinguish chamber; and the outline of the cross section of the guide hole is matched with that of the cross section of the vacuum arc extinguish chamber guide sleeve. When the solid-sealing pole rod is cast, the guide sleeve of the vacuum arc extinguish chamber moving conducting rod is cast in an insulating material to be embedded and fixed in the solid-sealing pole rod; when a torsion force is applied to the vacuum arc extinguish chamber moving conducting rod, the force is transferred to the insulating material of the solid-sealing pole rod through the vacuum arc extinguish chamber moving conducting sleeve; and forces applied to a cover plate and a corrugated pipe at the moving end of the vacuum arc extinguish chamber are obviously reduced.
Description
[technical field]
The utility model belongs to the electic protection technical field, relates to a kind of protection and control device of electric equipment, especially a kind of pole.
[background technology]
The anti-function of reversing of vacuum interrupter moving conductive rod is an indispensable function, is to realize by restriction moving conductive rod and relatively rotating of fairlead.The rotation of relative vacuum arc control device moved end end cap and bellows in case bearing the strength of reversing in installation or use, moving conductive rod takes place, bellows very easily is damaged, thereby influence the useful life of vacuum interrupter, serious meeting directly destroys the leak-tight system of arc control device, cause arc control device gas leakage, therefore the vacuum degree of arc control device reduce, thereby can't use.After the arc control device generation vacuum degree of running status reduces, can cause insulation fault even cut-off the state of failure.Usually just carry out other operations after tool using restriction arc control device moving conductive rod prevents to rotate in the direct installation process of vacuum interrupter.
Anti-the reversing of vacuum interrupter is the anti-rotating function that depends on arc control device self fully in the pole at present.But vacuum interrupter is cast in the insulating material of pole, is difficult to fixedly vacuum interrupter of tool using, also is difficult to possess specific purpose tool when keeping in repair at the scene and operates.Therefore pole is in plant produced, prevent the restriction of torsion problem because of being subjected to vacuum interrupter in using at the scene, exist in the production process assembly technology complexity, benefit low, to the problem of frock dependency degree; Exist in use and the maintenance maintenance process and destroy the vacuum extinction chamber air-tightness, cause the hidden danger of the leak-tight system inefficacy of vacuum interrupter, the safe operation of switching devices and the reliability service of network system cause potential threat.
[utility model content]
The purpose of this utility model provides a kind of pole, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
A kind of pole comprises: pole insulator, vacuum interrupter and vacuum interrupter moving conductive rod; It is non-circular vacuum interrupter fairlead that cross-sectional profiles is installed on the described vacuum interrupter moving conductive rod; Vacuum interrupter is flush-mounted in the described pole insulator, described pole insulator is provided with the pilot hole that described vacuum interrupter fairlead is installed in the vacuum interrupter moved end, the cross-sectional profiles of described pilot hole matches with the cross-sectional profiles of described vacuum interrupter fairlead.
The utility model further improves and is: described pole also comprises inserts and following inserts; The described inserts of going up is fixed in the quiet end of vacuum interrupter, and described inserts down and described vacuum interrupter moving conductive rod electrically connect.
The utility model further improves and is: the cross-sectional profiles of described vacuum interrupter fairlead is a polygon.
The utility model further improves and is: the cross-sectional profiles of described vacuum interrupter fairlead is for oval.
Compared with prior art, the utlity model has following advantage: a kind of pole of the utility model, during the cast pole, the fairlead of vacuum interrupter moving conductive rod is cast in the insulating material, fairlead is embedded and be fixed in the pole, when the vacuum interrupter moving conductive rod is subjected to reversing strength, by vacuum interrupter action-oriented cover with strength transmission to the insulating material of pole, the strength that vacuum interrupter moved end cover plate and bellows bear significantly reduces.Mill flat present situation in conjunction with existing vacuum interrupter moving conductive rod again, constitute moving conductive rod anti-rotation of the present utility model system jointly.The utility model can simple and effective enhancing pole anti-torsion capacity, reduce in the pole the vacuum extinction chamber interior install and use in bear and reverse strength, reduced the possibility that pole and vacuum interrupter wherein lost efficacy, increased the convenience of the Installation and Debugging of pole, guarantee the electric property of pole, promoted the useful life of pole.
[description of drawings]
