Abstract
The utility model relates to a dry high voltage wall bushing. The utility model is composed of a primary conductor, voltage-sharing balls, wire connecting terminals, an insulating winding layer, an insulating outer sheath and a flange, wherein, the voltage-sharing balls and the wire connecting terminals are arranged on both ends of the primary conductor; the insulating winding layer and the insulating outer sheath are wound outside the primary conductor. The utility model is characterized in that the primary conductor is provided with a back taper structure, and the exterior is wound by the insulating winding layer; the exterior of the insulating winding layer is provided with a high-strength tubular support; the exterior of the tubular support is the insulating outer sheath; the flange is fixed to the middle part of the high-strength tubular support and is electrically connected with a ground shield part of the insulating winding layer; the back taper structure can prevent insulating materials from falling off or sliding on a skeleton. Compared with primary insulation of a non back taper structure, the primary insulation has the advantages of high stability and strong shock resistance.
Description
Technical field
The utility model relates to a kind of wall bushing, the dry-type high-voltage wall bushing of the conduction usefulness in particularly a kind of 35kV and the above electrical network.
Background technology
At present, the dry-type high-voltage wall bushing that has a kind of interior external insulation to make on the market for the organic synthesis material, as shown in Figure 1, the feature of this high-voltage wall bushing is: Primary Conductor (or claim carrying object) 30 is passed the endoporus of the tubulose rigid backbone 70 that non-magnetic material makes, the tubulose rigid backbone 70 outer insulating barriers 40 that alternately hold, the outside of insulating barrier 40 is with the insulation oversheath 50 with full skirt, the centre of insulation oversheath 50 and the middle fixed outside that holds insulating barrier 40 have flange 60, are provided with voltage equalizing ball 20 and binding post 10 in the two ends of Primary Conductor 30.Because the primary insulation of this kind high-voltage wall bushing surrounds on the tubular structure, can cause the sliding screen of insulating barrier, come off, the fail safe of wall bushing is reduced; Tubulose rigid backbone diameter is less, makes the anti-short circuit capability of wall bushing lower.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned deficiency at prior art, and a kind of dry-type high-voltage wall bushing that stability is higher, fail safe is higher, anti-short circuit capability is stronger that insulate is provided.
Above-mentioned technical problem of the present utility model is realized by following technical scheme.
A kind of dry-type high-voltage wall bushing is by Primary Conductor, the voltage equalizing ball of being located at the Primary Conductor two ends and binding post, is paperwrapped in the outer insulating bag of Primary Conductor and is constituted around layer and insulation oversheath, flange, it is characterized in that:
This Primary Conductor has the back taper structure, holds insulating bag around layer outside it, and insulating bag is provided with the double-strength pipe shape and supports outside layer, and the outside of tubular support is fixed on the insulation oversheath for insulation oversheath, flange, and shields in the part on the ground of insulating bag around layer.
Except that above-mentioned essential features, in specific implementation process, also can not become following technology contents:
Primary Conductor with back taper structure is solid conductor or tubular shape conductor, and this back taper structure is metal or nonmetallic, and this back taper structure and Primary Conductor be one or split.
The high strength tubulose support be one or segmentation connects; It is nonmetal around the high-pressure section of layer that the high strength tubulose is supported on insulating bag.
Is metal or nonmetallic at insulating bag around the ground of layer screen part.
Between layer, be full of dielectric in support of high strength tubulose and insulating bag.
The utility model has the advantages that: overcome existing dry-type high-voltage wall bushing insulating bag around the easily sliding problem of shielding, coming off of layer, reduced insulating material, improved anti-short circuit capability, the fail safe of wall bushing is improved.
For structure of the present utility model, feature and effect thereof are had further understanding, enumerate specific embodiment now and be described with reference to the accompanying drawings as follows:
Description of drawings
Fig. 1 is the structural representation of existing high-voltage wall bushing.
Fig. 2 is the structural representation of high-voltage wall bushing of the present utility model.
Embodiment
As shown in Figure 2.A kind of high-voltage wall bushing provided by the utility model is by Primary Conductor 3, the voltage equalizing ball 2 of being located at Primary Conductor 3 two ends and binding post 1 and be paperwrapped in Primary Conductor 3 outer insulating bags is constituted around layer 4 and insulation oversheath 6, flange 7, wherein:
This Primary Conductor 3 has the back taper structure, hold insulating bag around layer 4 outside it, insulating bag is provided with the double-strength pipe shape and supports 5 outside layer 4, and the outside of tubular support 5 is insulation oversheath 6, flange 7 is fixed on the insulation oversheath 6, and shields in the part on the ground of insulating bag around layer 4.
This Primary Conductor 3 with back taper structure is that solid conductor also can be a tubular shape conductor; This back taper structure can be made with metal material, also can make with nonmetallic materials; And this back taper structure and Primary Conductor can be integrated or splits.
It is one whole that the high strength tubulose supports 5, also can be that segmentation connects; It is nonmetal at insulating bag around the high-pressure section of layer 4 that the high strength tubulose supports 5.
Can be metal or nonmetallic at insulating bag around the ground of layer 4 screen part.
Between layer 4, be full of dielectric in support 5 of high strength tubulose and insulating bag.
