Abstract
The utility model discloses a high strength rod porcelain insulator for a high speed railway electrified railway contact net. The high strength rod porcelain insulator comprises a porcelain piece, an upper steel cap and a lower steel cap. The porcelain piece is a solid porcelain body which can not be broken. Both the upper steel cap and the lower steel cap are provided with circular grooves which are clamped at two ends of the porcelain piece and are fixed through cement adhesive. The upper steel cap and a contact arm are fastened through bolts at the middle of a pressing plate. The body of the porcelain piece is provided with large umbrellas and small umbrellas. According to the high strength rod porcelain insulator, the upper steel cap is connected with the touch arm in a mode of setting the pressing plate for fastening, thus a phenomenon that the connection between a cap opening and the arm slides easily is solved completely, the safety and reliability of high speed railway electrified railway contact net operation are raised, large umbrella and small umbrella arrangement is employed by the appearance of the porcelain piece, thus the electric clearance of a product is raised to the maximum, and the phenomena of contact net pollution flashover are reduced.
Description
Technical field
The utility model relates to a kind of insulator, particularly a kind of high ferro contact nets in electrified railways high strength bar-shaped porcelain insulator.
Background technology
China's high ferro electric railway mileage is more and more at present, and contact nets in electrified railways with bar-shaped porcelain insulator as play support, insulating effect on electrical network, this has also proposed requirements at the higher level to the mechanical performance of electric railway bar-shaped porcelain insulator and electric property, under the serious environment for use of current filthy condition, easily there is pollution flashover phenomenon, the insulator of original structure only adopts pressing plate mode to be connected with bracket, while being given a shock, easily slide, above phenomenon affects high ferro traffic safety.
Utility model content
The purpose of this utility model is to provide a kind of high ferro contact nets in electrified railways high strength bar-shaped porcelain insulator that is not easy to occur pollution flashover and slip under high speed, filthy serious environment.
For achieving the above object, the utility model provides following technical scheme:
High ferro contact nets in electrified railways high strength bar-shaped porcelain insulator, comprising: porcelain piece, upper steel cap and lower steel cap; The solid porcelain body of described porcelain piece for puncturing; Described upper steel cap and lower steel cap are provided with the two ends that circular recess is connected to porcelain piece, and fix by cement glue; Described upper steel cap with contact bracket by the bolted in the middle of pressing plate; The main body of described porcelain piece is provided with the umbrella group structure of gamp and umbellule arrangement spaced apart, and the two ends of umbrella group structure are gamp, and described gamp and umbellule are parallel to each other and the angle of itself and porcelain piece is 70-85 degree.
In the utility model, described upper steel cap and lower steel cap utilize cement glue to be separately fixed at the two ends up and down of porcelain piece, upper steel cap with by touching bracket, be connected, connected mode is carried out fastening for pressing plate is set, and in the middle of pressing plate, adopt logical bolt mode to fix, thereby thoroughly solve cap mouth, be connected with bracket by the locomotive high-speed motion generation vibration phenomenon that easily generation is slided, greatly improved the safety and reliability that high ferro electrified contacting nets moves.It is arranged evenly that porcelain piece profile adopts large umbellule to be interrupted, and porcelain piece two ends are all set to gamp, thereby improved to greatest extent the electric clearance of product, thereby improved the antifouling property of product, reduced the phenomenon of contact line generation pollution flashover.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure: the upper steel cap of 1-, steel cap under 2-, 3-porcelain piece, 4-cement glue, 5-gamp, 6-umbellule.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, high ferro contact nets in electrified railways high strength bar-shaped porcelain insulator, comprising: porcelain piece 3, upper steel cap 1 and lower steel cap 2; The solid porcelain body of described porcelain piece 3 for puncturing; Described upper steel cap 1 and lower steel cap 2 are provided with the two ends that circular recess is connected to porcelain piece 3, and fixing by cement glue 4; The main body of described porcelain piece 3 is provided with the umbrella group structure of gamp 5 and umbellule 6 arrangements spaced apart, and the two ends of umbrella group structure are gamp 5, and described gamp 5 and umbellule 6 are parallel to each other and the angle of itself and porcelain piece is 70-85 degree.
Installation method of the present utility model: described upper steel cap 1 and lower steel cap 2 utilize cement glue 4 to be separately fixed at the two ends up and down of porcelain piece 3, described upper steel cap 1 with by touching bracket, be connected, connected mode is carried out fastening for pressing plate is set, and fix U-bolt cover and pressing plate are reinforced by hex nut in the logical bolt mode of the middle employing of pressing plate, with two, add logical bolt in the middle of pressing plates and through bracket pipe, add fastening nuts and be connected, thereby thoroughly solve insulator and bracket sliding phenomenon.It is arranged evenly that the umbrella of porcelain piece 3 adopts large and small umbrella to be interrupted, and porcelain piece 3 upper/lower terminals are gamp, and product electric clearance is increased, and protection creep distance increases, thereby has greatly improved the filthy tolerance of product.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
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 make specification as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other execution modes that it will be appreciated by those skilled in the art that.
