Abstract
The utility model discloses a supporting insulator, comprising a porcelain member, an upper flange, and a lower flange. The porcelain member is provided with large umbrella skirts, small umbrella skirts, and a tubular porcelain member body. The large umbrella skirts and the small umbrella skirts are disposed on the periphery of the porcelain member body. The large umbrella skirts and the small umbrella skirts are arranged in a spaced manner. The upper flange and the lower flange are respectively adhered on two ends of the porcelain member body through cement adhesive. The supporting insulator has good mechanical strength, large creep distance, and good insulating property.
Description
Technical field
The utility model relates to a kind of post insulator.
Background technology
At present, porcelain insulator is the important component part of transformer station and transmission line, and Main Function is that wire is connected on support, plays insulation, mechanical connection and supporting role.The key of transmission line reliability service is the quality of insulator, on the use history of insulator, because its mechanical strength is not good, fracture accident once frequently occurred, to national economy, production has brought the loss that can't estimate, has become the potential safety hazard of power department maximum at present.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, provides a kind of mechanical strength good, and creepage distance is large, the post insulator of good insulation preformance.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of post insulator, it comprises porcelain piece, upper flange and lower flange, porcelain piece has the porcelain piece body of large full skirt, little full skirt and tubular, large full skirt and little full skirt are arranged on the periphery of porcelain piece body, and large full skirt and little full skirt are arranged shape at interval, and described upper flange and lower flange are glued at respectively the two ends of porcelain piece body by cement glue.
Further, described large full skirt is provided with five, and described little full skirt is provided with four, and described little full skirt is between adjacent large full skirt.
Further, the diameter a of described porcelain piece body is 110 millimeters, and the length L of described porcelain piece body is 526 millimeters.
Further, the diameter b of described large full skirt is 245 millimeters, and the diameter of described little full skirt is that c is 215 millimeters.
After having adopted technique scheme, the upper flange of this insulator and lower flange are glued at respectively the two ends of porcelain piece body by cement glue, and the use of cement glue causes insulator mechanical strength very strong.The long-time use, upper flange or lower flange can not split away off yet, in addition, the arrangement architecture of large full skirt, little full skirt with and size make the creepage distance of this insulator large, good insulation preformance.
The accompanying drawing explanation
The structural representation that Fig. 1 is post insulator 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 post insulator, it comprises porcelain piece 1, upper flange 2 and lower flange 3, porcelain piece 1 has the porcelain piece body 1-3 of large full skirt 1-1, umbellule skirt 1-2 and tubular, large full skirt 1-1 and umbellule skirt 1-2 are arranged on the periphery of porcelain piece body 1-3, and large full skirt 1-1 and umbellule skirt 1-2 arrange shape at interval, and described upper flange 2 and lower flange 3 are glued at respectively the two ends of porcelain piece body 1-1 by cement glue 4.
Large full skirt 1-1 is provided with five, and umbellule skirt 1-2 is provided with four, and umbellule skirt 1-2 is between adjacent large full skirt 1-1.
The diameter a of porcelain piece body 1-3 is 110 millimeters, and the length L of porcelain piece body 1-3 is 526 millimeters.
The diameter b of large full skirt 1-1 is 245 millimeters, and the diameter of umbellule skirt 1-2 is that c is 215 millimeters.
The upper flange 2 of this insulator and lower flange 3 are glued at respectively the two ends of porcelain piece body 1-1 by cement glue 4, the use of cement glue 4 causes insulator mechanical strength very strong.The long-time use, upper flange 2 or lower flange 3 can not split away off yet, in addition, the arrangement architecture of large full skirt 1-1, umbellule skirt 1-2 with and size make the creepage distance of this insulator large, good insulation preformance.
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.
