Abstract
The utility model relates to the technical field of an electric material, in particular to a support post ceramic sleeve used for10 kV. The support post ceramic sleeve comprises a ceramic post in the middle and flanges at both ends, wherein the ceramic post in the middle is a cylindrical hollow part, large umbrellas and small umbrellas with large and small spaces are also arranged outside the ceramic post, the ceramic post has the length of 2450 mm, the cylinder of the hollow part has the diameter of 360 mm, the large umbrellas are twenty nine, the small umbrellas are twenty eight, the diameter of the large umbrellas is 590 mm, the diameter of the small umbrellas is 560 mm, the height of the flanges is 125 mm, and the outer diameter of the flanges is 515 mm. The ceramic sleeve with the structure has the advantages that the creep age distance is large and can reach 9100 mm, the bending resistance failure moment is not smaller than 20 kN*m, the regular bending tolerance load is 14 kN*m, the top bending failure moment is not smaller than 10 kN*m, the lightning surge peak is 1250 kV, and the utility model can be widely used in the fields of mines, railways and the like.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the strut porcelain bushing of a kind of 10KV of applying to.
Background technology
Strut porcelain bushing, the porcelain knob in the middle of comprising and the ring flange at two ends, at present, relate to the pillar device insulator that applies to the such voltage levels of 10KV, have the phenomenon of unreasonable structure, cause its degree on withstand voltage degree, creepage distance does not reach requirement on the bending resistance destrabilizing moment, influences its serviceability.
Summary of the invention
Technical problem to be solved in the utility model provides the pillar device insulator that a kind of tolerance is higher, creep distance big, the bending resistance destrabilizing moment is big.
Technical solution adopted in the utility model is; A kind of pillar device insulator, the porcelain knob in the middle of comprising and the ring flange at two ends is characterized in that: middle porcelain knob is one and has columniform hollow parts, outside gamp and the umbellule that also has size interval; The length of described porcelain knob is 2450mm, and the columniform diameter of hollow parts is 360mm; 29 of gamps and umbellule are 28, and the gamp diameter is 590mm, and the umbellule diameter is 560mm, and the height of ring flange is 125mm, and the outer dia of ring flange is 515mm.
The beneficial effects of the utility model are: it is big that such insulator has a creepage distance, can reach 9100mm, and the bending resistance destrabilizing moment is not less than 20kN.m; Customary crooked tolerance load 14kN.m, top curved is destroyed load and is not less than 10kN.m, lightning impulse peak value 1250KV.
