Abstract
The utility model discloses a lightning arrester pedestal porcelain shell, comprising a porcelain insulator, an upper flange, and a lower flange. The porcelain insulator is provided with a through-hole used for threading. An umbrella skirt is disposed on an outer wall of the porcelain insulator. The upper flange and the lower flange are both provided with porcelain insulator mounting holes, and walls of the porcelain insulator mounting holes are coated with asphalt layers. Two ends of the porcelain insulator are respectively adhered in the porcelain insulator mounting holes through cement adhesive, and adhesion positions on two ends of the porcelain insulator are coated with the asphalt layers. The lightning arrester pedestal porcelain shell can prevent extrusion and damaging phenomenon in a manufacturing process, and has strong mechanical connection strength.
Description
Technical field
The utility model relates to a kind of porcelain bushing for lightning protector base, belongs to the lightning arrester technical field.
Background technology
At present, in making the lightning arrester process, because upper flange, lower flange and porcelain piece have different shrinkages, during making, it is damaged that its bonded part is easy to extruding, and use for a long time, upper and lower flange also there will be certain loosening phenomenon, and its mechanical connection intensity is not high yet.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of porcelain bushing for lightning protector base is provided, and it not only can avoid the extruding disrepair phenomenon in manufacturing process, and mechanical connection intensity is large.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of porcelain bushing for lightning protector base, comprise porcelain piece, upper flange and lower flange, have the through hole of wearing wire on porcelain piece, be provided with a full skirt on the outer wall of porcelain piece, all have the porcelain piece installing hole on upper flange and lower flange, and be coated with bitumen layer on the hole wall of porcelain piece installing hole, the two ends of described porcelain piece are glued in the porcelain piece installing hole by cement glue respectively, and also be coated with bitumen layer on the gummed position at porcelain piece two ends.
Further, be provided with a plurality of annular recess on the hole wall of described porcelain piece installing hole.
Further, the diameter d of described porcelain piece is 200 millimeters, and the diameter e of described full skirt is 310 millimeters.
Further, the length H of described whole insulator is 314 millimeters.
Further, described porcelain piece is bice glaze.
After having adopted technique scheme, the utility model adopts bitumen layer in bonded part, this bitumen layer has the cushioning effect of being extruded, in manufacturing process, upper flange, lower flange and porcelain piece there will be different shrinkages, and bitumen layer can be born this extruding, thereby avoid the extruding disrepair phenomenon in manufacturing process, and the employing cement glue, its mechanical connection intensity is large; In addition, the annular groove on upper flange and lower flange, after can avoiding long-term the use, the loosening phenomenon up and down that upper flange and lower flange occur.
The accompanying drawing explanation
The structural representation that Fig. 1 is porcelain bushing for lightning protector base of the present utility model.
Embodiment
For content of the present utility model more easily is expressly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of porcelain bushing for lightning protector base, comprise porcelain piece 1, upper flange 2 and lower flange 3, have the through hole 1-1 that wears wire on porcelain piece 1, be provided with a full skirt 1-2 on the outer wall of porcelain piece 1, all have porcelain piece installing hole 23 on upper flange 2 and lower flange 3, and be coated with bitumen layer on the hole wall of porcelain piece installing hole 23, the two ends of porcelain piece 1 are glued in porcelain piece installing hole 23 by cement glue 4 respectively, and also are coated with bitumen layer on the gummed position at porcelain piece 1 two ends.
Be provided with a plurality of annular recess 23-1 on the hole wall of porcelain piece installing hole 23.
The diameter d of porcelain piece 1 is 200 millimeters, and the diameter e of full skirt 1-2 is 310 millimeters.
The length H of whole insulator is 314 millimeters.
Porcelain piece 1 is bice glaze.
The utility model adopts bitumen layer in bonded part, this bitumen layer has the cushioning effect of being extruded, in manufacturing process, upper flange 2, lower flange 3 and porcelain piece 1 there will be different shrinkages, bitumen layer can be born this extruding, thereby avoid the extruding disrepair phenomenon in manufacturing process, and adopt cement glue 4, its mechanical connection intensity is large; In addition, the annular groove 23-1 on upper flange 2 and lower flange 3, after can avoiding long-term the use, the loosening phenomenon up and down that upper flange 2 and lower flange 3 occur.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
