Description
Technical field
The present invention relates to transformer manufacturing domain, more particularly to a kind of outlet structure of Transformer Winding end electrostatic ring.
Background technology
Electric power transformer insulated is power transformer, particularly the important component of superhigh tension power transformer, and it is not
But it is marginal to separate unit power-carrying and the operational reliability tool of transformer, and to the economic indicator of transformer, tool
Have a major impact.Transformer overhang insulation is part important in major insulation again, because the electric field pole at this is uneven, institute
To improve the impulse voltage distributions of wire turn end and adjacent all line segments in high-voltage product mesohigh winding, moreover it is possible to make winding terminal
Portion's electric fields uniform adds electrostatic ring mode to meet to require using end.Electrostatic ring makes main insulating structure except that can improve Analysis of End Electric Field
Outside having reduced, also the turn-to-turn Potential distribution of first line segment (particularly Continuous winding) is greatly improved.Therefore, it is quiet
The outlet of electric ring must weld together with first wire turn, can be only achieved expected effect.But due to electrostatic as shown in Figure 2
The outlet of ring and the welding position of wire turn all in end non-uniform electric field, and it two again it is very small in same position gap,
Processing to welding brings difficulty with insulating wrapping, does not pay attention to slightly product will being made potential safety hazard to be present.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of outlet structure of Transformer Winding end electrostatic ring, carry
High electrostatic ring outlet and the operability of welding position insulating wrapping, eliminate safe hidden trouble, make product more safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is：A kind of outlet of Transformer Winding end electrostatic ring
Structure, it includes Transformer Winding body；The Transformer Winding body includes wire turn and electrostatic ring；Along circle on the electrostatic ring
The evenly distributed multiple cross-over blocks of circumferential direction；The electrostatic ring wherein the right side of a cross-over block position set electrostatic ring
Outlet；The wire turn is provided with wire turn pad in the position in the left side of same dielectric cushion block；Electrostatic ring outlet and wire turn welding
The bottom of cross-over block between point is provided with the cross-over block breach for wearing electrostatic ring outlet.
The width of the cross-over block breach is 35-45mm, thickness 3-5mm.
Beneficial effects of the present invention：The outlet structure of a kind of Transformer Winding end electrostatic ring of the present invention, by will be quiet
The position of electric ring outlet is staggered completely with the position welded, and facilitates outlet and the welding of wire turn, improves outlet and welding position is exhausted
The operability of edge wrapping, eliminates safe hidden trouble, and improves product quality, it is ensured that the reliability service of product.

Block 4；The position on the electrostatic ring right side of a cross-over block 4 wherein sets electrostatic ring outlet 5；The wire turn 2 is identical
The position in the left side of cross-over block 4 is provided with wire turn pad 6；Cross-over block between electrostatic ring outlet 5 and wire turn pad 6
4 bottom is provided with the cross-over block breach 7 for wearing electrostatic ring outlet；The width of the cross-over block breach 7 is 40mm,
Thickness is 4mm.
A kind of outlet structure of Transformer Winding end electrostatic ring of the present embodiment, one grade is moved by wire turn pad backward,
The position of electrostatic ring outlet and wire turn pad is allowed not on same shelves, electrostatic ring outlet head is stretched to wrap and insulated through exhausted
The breach of edge cushion block, then welded with wire turn.
A kind of outlet structure of the Transformer Winding end electrostatic ring of the present embodiment, by by the position of electrostatic ring outlet with
The position of welding is staggered completely, facilitates outlet and the welding of wire turn, improves the operability of outlet and welding position insulating wrapping,
Eliminate safe hidden trouble, improve product quality, it is ensured that the reliability service of product.
As shown in Fig. 2 be the outlet structure of existing Transformer Winding end electrostatic ring, its electrostatic ring outlet and pad
Between two cross-over blocks of identical, gap is small, it has not been convenient to welding and insulating wrapping operation.
Above-described embodiment should not in any way limit the present invention, all to be obtained by the way of equivalent substitution or equivalency transform
Technical scheme all fall within protection scope of the present invention.
