Abstract
The utility model relates to an electric material, and in particular to a flaring insulator which is applicable to 126KV, which is characterized in that a middle knob insulator is of a flaring shape, i.e. a hollow part inside the knob insulator is gradually divided into a small cylinder, a round platform and a large cylinder from top to bottom, and the knob insulator has the same thickness, so the appearance of the knob insulator is also of a flaring shape. The length of the knob insulator is 1225 mm, the height of the small cylinder is 120 mm, the height of the round platform is 556 mm, and the height of the large cylinder is 549 mm. The exterior of the knob insulator is also provided with gamps and umbellules which are arranged at a distance from each other, and the quantity of the gamps and the umbellules is respectively 15. The flaring insulator has the advantages that the creepage distance is large, the bending-resistant destabilizing moment is large and the enduring degree is high. The flaring insulator is applicable to the fields such as mines and railways.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the loudspeaker insulator of a kind of 126KV of applying to.
Background technology
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 insulator that applies to the such voltage levels of 126KV, 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 tubaeform 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 flaring insulator, the porcelain knob in the middle of comprising and the ring flange at two ends is characterized in that: middle porcelain knob is flaring, and promptly the hollow parts of the inside of porcelain knob is followed successively by small column-round platform-big column from top to bottom, porcelain knob has identical thickness, and the outside of formation also is flaring.The length of described porcelain knob is 1225mm, and the height of small column is 120mm, and the height of round platform is 556mm, and the height of big column is 549mm.Described porcelain knob outside also has spaced gamp and umbellule, each 15 of gamp and umbellules.
The beneficial effects of the utility model are: it is big that such insulator has a creepage distance, can reach 3150mm, and the bending resistance destrabilizing moment is big; Also has the high advantage of tolerance degree.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of flaring insulator, the porcelain knob 1 in the middle of comprising and the ring flange 2 at two ends, it is characterized in that: middle porcelain knob 1 is flaring, the hollow parts that is the inside of porcelain knob 1 is followed successively by small column 6-round platform 7-big column 8 from top to bottom, porcelain knob 1 has identical thickness, and the outside of formation also is flaring.The long L of described porcelain knob is 1225mm, the high h of small column
1Be 120mm, the high h of round platform
2Be 556mm, the high h of big column
3For the described porcelain knob of 549mm. outside also has spaced gamp and umbellule, each 15 of gamp and umbellules.
The utility model in the utilization of fields such as mine, railway extensively.
