Abstract
The utility model relates to an electric material, in particular to a porcelain bushing of a 10KV lightning arrester. The porcelain bushing of the lightning arrester comprises a porcelain column in the middle and flange plates at the two ends, and is characterized in that a large umbrella and a small umbrella are respectively arranged at the two ends of the porcelain column; a cylinder-shaped outer body is arranged in the middle of the porcelain column; the length of the porcelain bushing is 1875mm; a hollow part with the diameter of 145mm is arranged inside the porcelain column; the diameter of the large umbrella is 379mm; and the diameter of the small umbrella is 339mm. Owing to the adoption of the above structure, the porcelain bushing of the lightning arrester has the characteristics that: the creepage distance is as long as 5965mm, and the bending and breaking moment is not less than 42.5Kn.m, thereby meeting strict requirements of a certain electric power.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the lightning arrester insulator of a kind of 10KV of applying to.
Background technology
The lightning arrester insulator, the porcelain knob in the middle of comprising and the ring flange at two ends, at present, it mostly is columniform relating to the lightning arrester insulator that applies to the such voltage levels of 10KV, be that the hollow of porcelain knob inside is a cylinder that floor space is identical, such insulator has the advantages that creepage distance is short, fail safe is not high, tolerance is not strong; Existing in addition insulator also has shortcoming on design size, be difficult to satisfy the client to creepage length, tolerance height, requirement that moment of torsion is big.
Summary of the invention
Technical problem to be solved in the utility model provides the 10KV lightning arrester insulator that a kind of tolerance is higher, creep distance is big.
Technical solution adopted in the utility model is; A kind of lightning arrester insulator, the porcelain knob in the middle of comprising and the ring flange at two ends, it is characterized in that: middle porcelain knob is that the outside respectively has two gamps and umbellule up and down, the ectosome that one cylindrical section shape is arranged in the middle of the porcelain knob, the length of described insulator is 1875mm, and porcelain knob inside has a hollow parts, and the diameter of hollow parts is 145mm, the diameter of described gamp is 379mm, and the diameter of umbellule is 339mm.
The beneficial effects of the utility model are: it is big that such lightning arrester insulator has a creepage distance, can reach 5965mm; Insulator bending failure moment is not less than the effect of 42.5Kn.m, can satisfy the requirement of the harsh volume of some electric power.
