Abstract
The utility model relates to a transformer electrostatic ring with a nesting structure, which belongs to the technical field of transformers. In the technical scheme, the transformer electrostatic ring comprises an inner electrostatic ring (1), an outer electrostatic ring (2), insulating spacers (3) between the inner electrostatic ring and the outer electrostatic ring and crepe paper, the insulating spacers and the crepe paper are arranged between the inner electrostatic ring and the outer electrostatic ring of the nesting structure, the outer electrostatic ring is provided with an opening (4), and an inner electrostatic ring outlet (5) exposes via the opening. The transformer electrostatic ring has the beneficial effects that: the radial size of the electrostatic ring is reduced, the working efficiency is increased, and the transformer electrostatic ring is suitable for use on ultrahigh-voltage high-capacity transformers.
Description
Technical field:
The utility model relates to a kind of transformer electrostatic ring of interior jacket structure, belongs to the transformer technology field.
Background technology:
In the transformer, in order to improve winding overhang or near the Electric Field Distribution of the inlet line segment, at winding overhang electrostatic ring is set, its effect is that the winding overhang non-uniform electric field is become even a little, to improve the dielectric strength of end.Electrostatic ring is made skeleton by the laminated paper circle, outsourcing conductive metal band, equipotential line and insulating barrier.But along with continuous advancement in technology, constantly succeeding in developing of new product, the voltage and the capacity of product are increasing, this just requires electrostatic ring radial than before increasing, when the radial size of electrostatic ring surpassed certain size, the lathe of existing coiling electrostatic ring insulation can not reach the coiling requirement, can only rely on the wrapping of manually insulating, this just need expend a lot of manpower and materials and time, and the big precision of wrapping difficulty is not high yet.
The utility model content:
The utility model purpose provides a kind of transformer electrostatic ring of interior jacket structure, has reduced the radial of electrostatic ring, increases work efficiency, and solves the problems referred to above that background technology exists.
The technical solution of the utility model is: the transformer electrostatic ring of interior jacket structure, comprise cross-over block, crimped paper between interior electrostatic ring, outer electrostatic ring, inside and outside electrostatic ring, cross-over block and crimped paper between inside and outside electrostatic ring is set between the interior electrostatic ring of interior jacket structure, the outer electrostatic ring, outer electrostatic ring is provided with opening, and interior electrostatic ring lifts one's head to come out by opening.
Interior electrostatic ring is lifted one's head, outer electrostatic ring is lifted one's head and is arranged side by side.
The utility model is by being divided into former radial big electrostatic ring inside and outside two little radial electrostatic rings, place cross-over block as heat dissipation channel between the inside and outside electrostatic ring, cross-over block is coated with PVA and adjacent elements cements and stretching electrostatic ring and lead, is having the cross-over block place firm inside and outside electrostatic ring colligation with crimped paper at last.
The beneficial effects of the utility model are: reduced the radial of electrostatic ring, increased work efficiency, the utility model suits to adopt on extra-high-voltage large-capacity transf.
Description of drawings:
Fig. 1 is the utility model example structure schematic diagram;
Among the figure: cross-over block 3, opening 4, interior electrostatic ring lift one's head 5 between interior electrostatic ring 1, outer electrostatic ring 2, inside and outside electrostatic ring, outer electrostatic ring lifts one's head 6.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The transformer electrostatic ring of interior jacket structure, comprise cross-over block 3, crimped paper between interior electrostatic ring 1, outer electrostatic ring 2, inside and outside electrostatic ring, cross-over block and crimped paper between inside and outside electrostatic ring is set between the interior electrostatic ring of interior jacket structure, the outer electrostatic ring, outer electrostatic ring is provided with opening 4, and interior electrostatic ring lifts one's head 5 to come out by opening.Interior electrostatic ring is lifted one's head, outer electrostatic ring is lifted one's head and 6 is arranged side by side.
Claims (2)
1. the transformer electrostatic ring of jacket structure in a kind, it is characterized in that comprising cross-over block (3), crimped paper between interior electrostatic ring (1), outer electrostatic ring (2), inside and outside electrostatic ring, cross-over block and crimped paper between inside and outside electrostatic ring is set between the interior electrostatic ring of interior jacket structure, the outer electrostatic ring, outer electrostatic ring is provided with opening (4), interior electrostatic ring lift one's head (5) come out by opening.
According to claim 1 described within the transformer electrostatic ring of jacket structure, in it is characterized in that electrostatic ring lift one's head, outer electrostatic ring lift one's head (6) be arranged side by side.
