Abstract
The utility model belongs to the technical field of electrical materials and appliances, and in particular relates to a drum-shaped insulator applied to 10 kV. The drum-shaped insulator comprises a middle knob insulator and ring flanges arranged at two ends, wherein the middle knob insulator is drum-shaped, namely, the centre of a hollow part in the knob insulator is provided with a large cylinder, outwards from the large cylinder, the knob insulator is provided with a round platform of which the large bottom is in the same bottom plane as the cylinder, and the two ends of the knob insulator are provided with small cylinders respectively of which the bottom surfaces are in the same bottom plane as the small bottom of the round platform; the knob insulator is 1,840 mm long; the small cylinder at one end, the round platform, the large cylinder, the round platform and the small cylinder at the other end are 146 mm high, 724 mm high, 2,978 mm high, 410 mm high and 150 mm high respectively; and 20 large umbrellas and 20 small umbrellas arranged at intervals are also arranged outside the knob insulator. The drum-shaped insulator has the characteristics of long creepage distance, large internal water pressure destabilizing moment and large insulator bending destabilizing moment, and can be widely applied 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 cydariform insulator of a kind of 10KV 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 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 insulator that a kind of tolerance is higher, creep distance is big.
Technical solution adopted in the utility model is; A kind of cydariform 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 a cydariform, the hollow parts centre that is the inside of porcelain knob is a large cylinder, large cylinder outwards is respectively a round platform, the big end of round platform and the same end of cylinder,, two ends are respectively small columns, the bottom surface of small column and the same end of round platform handle; Described porcelain knob length is 1840mm, is respectively 146mm, 724mm, 2978mm, 410mm, 150mm from the height of the small column of an end, round platform, big column, round platform, small column; Described porcelain knob outside also has spaced gamp and umbellule, each 20 of big umbellules.
The beneficial effects of the utility model are: it is big that such insulator has a creepage distance, can reach 5680mm; The hydraulic pressure destrabilizing moment is not less than 3.7Mpa in the insulator; Insulator bending failure moment is not less than the effect of 35Kn.m, can satisfy the requirement of the harsh volume of some electric power.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of cydariform insulator, the porcelain knob 1 in the middle of comprising and the ring flange 2 at two ends is characterized in that: middle porcelain knob 1 is a cydariform, is a large cylinder in the middle of the hollow parts of the inside of porcelain knob 2 promptly, large cylinder outwards is respectively a round platform, the big end of round platform and the same end of cylinder,, two ends are respectively small columns, the bottom surface of small column and the same end of round platform handle, because the porcelain body that the porcelain knob outside has same thickness is so porcelain knob also is a cydariform.
Described porcelain knob length is 1840mm, is respectively 146mm, 724mm, 2978mm, 410mm, 150mm from the height of the small column of an end, round platform, big column, round platform, small column; Described porcelain knob outside also has spaced gamp and umbellule, each 20 of big umbellules.
The utility model in the utilization of fields such as mine, railway extensively.
