Abstract
The utility model discloses a kind of high-voltage capacitor press insert type outlet casing tube, comprises insulator, metal flange and sealing ring; The bottom of insulator is provided with the porcelain flange of evagination; Metal flange is coated and fixed on described porcelain flange; Sealing ring is fixed between insulator and metal flange.In the utility model, metal flange and insulator is embedding is integrated place, the bar footpath of insulator does not limit by rolling technology, and the intensity of sleeve pipe can not be affected.In the process that metal flange is rolled, insulator main body is not carried out, insulator can not be subject to the injury of roll extrusion power substantially, can eliminate the insulator damage hidden danger that may cause in rolling process.
Description
[technical field]
The utility model relates to T & D Technology field, particularly a kind of high-voltage capacitor press insert type outlet casing tube.
[background technology]
Refer to shown in Fig. 1, existing high-voltage capacitor outlet casing tube comprises steel flange 1 and insulator 2; Be combined into one by roll forming between steel flange 1 and insulator 2, be provided with by the sealing ring 3 compressing to carry out to seal between rust steel flange 1 and insulator 2; But roll extrusion is carried out on insulator 2.Just there is following shortcoming in this:
1, in order to be beneficial to roll extrusion, insulator 2 goes out to devise a rolling groove 20 in main body, and the bar footpath of the most strong point insulator of the arm of force is minimum, and intensity is minimum, and this design seriously reduces the intensity of sleeve pipe 2.
2, owing to being roll extrusion in insulator 2 main body, one is rolled in order to make steel flange 1 and insulator 2, must have an enough large roll extrusion power that steel flange 1 is out of shape to be integrated with insulator 2 is embedding, this strength often makes again insulator rolling groove place formation stress concentrate and damage, make insulator in capacitor production process and outdoor hanging net operation by the cold and hot variable effect of ambient temperature, and in rolling groove 20 place's brittle failure.
[utility model content]
The purpose of this utility model is to provide a kind of high-voltage capacitor press insert type outlet casing tube, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
High-voltage capacitor press insert type outlet casing tube, comprises insulator, metal flange and sealing ring; The bottom of insulator is provided with the porcelain flange of evagination; Metal flange is coated and fixed on described porcelain flange; Sealing ring is fixed between insulator and metal flange.
Preferably, the bottom of porcelain flange is provided with sealing ring storage tank, and the top of porcelain flange is curved; Sealing ring is fixed in described sealing ring storage tank.
Preferably, the bottom of the coated porcelain flange of metal flange and arc top.
Preferably, metal flange comprises sealing flange and adpting flange; Sealing flange is coated on porcelain flange, the bottom of the coated porcelain flange in bottom of sealing flange, and is fixed in sealing ring storage tank by sealing ring compression; The arc top of the coated porcelain flange in top of sealing flange; The adpting flange turned up is fixedly connected with sealing flange.
Preferably, adpting flange is fixedly connected with the equipment box docked.
Preferably, the adpting flange turned up is fixedly connected with the equipment box docked; Adpting flange is positioned at sealing flange outside with the equipment box junction of docking.
Preferably, the adpting flange turned up is weldingly fixed on the periphery of sealing flange.
Preferably, sealing flange and adpting flange are integral type structure.
Preferably, the external diameter of porcelain flange is greater than the diameter at the minimum place of radial diameter of insulator.
Relative to prior art, the utility model has following beneficial effect: in the utility model, metal flange and insulator is embedding is integrated place, and the bar footpath of insulator does not limit by rolling technology, and the intensity of sleeve pipe can not be affected.In the process that metal flange is rolled, insulator main body is not carried out, insulator can not be subject to the injury of roll extrusion power substantially, can eliminate the insulator damage hidden danger that may cause in rolling process.

Fig. 2 is the enlarged drawing in B portion in Fig. 1;
Fig. 3 is the structural representation of the utility model high-voltage capacitor press insert type outlet casing tube.
[embodiment]
A kind of high-voltage capacitor press insert type of the utility model outlet casing tube, comprises insulator 2, metal flange and sealing ring 3.Metal flange comprises sealing flange 11 and adpting flange 12.
The bottom of insulator 2 is provided with porcelain flange 21, and the external diameter of porcelain flange 21 is greater than the diameter at the minimum place of radial diameter of insulator 2; The bottom of porcelain flange 21 is provided with sealing ring storage tank 210, and the top of porcelain flange 21 is curved.
Sealing flange 11 is coated on porcelain flange 21 by roll extrusion, the bottom of the coated porcelain flange 21 in bottom of sealing flange 11, and is fixed in sealing ring storage tank 210 by sealing ring 3 compression; The arc top of the coated porcelain flange 21 in top of sealing flange 11.
Adpting flange 12 turns up and is welded on the periphery (but be not limited to periphery, also the welding region of two flanges can be extended the downside that be fixed to porcelain flange) of sealing flange 11; Adpting flange 12 is for being welded and fixed with the equipment box docked.
Sealing flange 11 and adpting flange 12 can be arranged to integral type, be enclosed within porcelain flange 21, and the top of top roll extrusion sealing flange 11 at porcelain flange 21, make the arc top of the coated porcelain flange 21 in the top of sealing flange 11, like this sealing flange, insulator and sealing ring are rolled into one.
Carry out on the porcelain flange 21 that the diameter of insulator 2 is larger during the utility model roll extrusion, stress can not be caused to concentrate.
In the utility model, metal flange and insulator is embedding is integrated place, the bar footpath of insulator does not limit by rolling technology, and the intensity of sleeve pipe can not be affected.In the process that metal flange is rolled, insulator main body is not carried out, insulator can not be subject to the injury of roll extrusion power substantially, can eliminate the insulator damage hidden danger that may cause in rolling process.
