Description
Technical field
The present invention relates to transformer manufacturing territory, particularly relate to the outlet structure of a kind of Transformer Winding end electrostatic ring.
Background technology
Electric power transformer insulated is power transformer, particularly the important component part of superhigh tension power transformer, and it is not
But marginal to the separate unit power-carrying of transformator and operational reliability tool, and to the economic indicator of transformator also, tool
Have a major impact.Transformator overhang insulation is again ingredient important in major insulation, owing to the electric field pole at this is uneven, and institute
With at high-voltage product mesohigh winding in order to improve the impulse voltage distributions of wire turn end and adjacent all line segments, moreover it is possible to make winding terminal
Portion's electric fields uniform uses end to add electrostatic ring mode to meet requirement.Electrostatic ring makes main insulating structure except improving Analysis of End Electric Field
Outside having reduced, also the turn-to-turn Potential distribution of first line segment (particularly Continuous winding) is had greatly improved.Therefore, quiet
The outlet of electricity 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 are all at end non-uniform electric field, and it is two the least in gap, same position again,
The process giving welding brings difficulty with insulating wrapping, does not the most note making product there is potential safety hazard.
Summary of the invention
For solving above-mentioned technical problem, the invention provides the outlet structure of a kind of Transformer Winding end electrostatic ring, carry
High electrostatic ring outlet and the operability of welding position insulating wrapping, eliminate safe hidden trouble, and makes product more safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: the outlet of a kind of Transformer Winding end electrostatic ring
Structure, it includes Transformer Winding body；Described Transformer Winding body includes wire turn and electrostatic ring；Along circle on described electrostatic ring
The evenly distributed multiple cross-over blocks of circumferential direction；The position on the described electrostatic ring right side of a cross-over block wherein arranges electrostatic ring
Outlet；Described 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 the cross-over block between point is provided with the cross-over block breach for wearing electrostatic ring outlet.
The width of described cross-over block breach is 35-45mm, and thickness is 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 by quiet
Staggering completely with the position welded in the position of electricity ring outlet, facilitates welding of outlet and wire turn, and raising outlet and welding position are exhausted
The operability of edge wrapping, eliminates safe hidden trouble, and improves product quality, it is ensured that the reliability service of product.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the outlet structure of a kind of Transformer Winding end electrostatic ring of embodiment；
Fig. 2 is the schematic diagram of the outlet structure of existing Transformer Winding end electrostatic ring.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention done and retouch the most in detail
Stating, this embodiment is only used for explaining the present invention, does not constitute protection scope of the present invention and limits.

Block 4；The position on the described electrostatic ring right side of a cross-over block 4 wherein arranges electrostatic ring outlet 5；Described 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
The bottom of 4 is provided with the cross-over block breach 7 for wearing electrostatic ring outlet；The width of described cross-over block breach 7 is 40mm,
Thickness is 4mm.
The outlet structure of a kind of Transformer Winding end electrostatic ring of the present embodiment, moves one grade by wire turn pad backward,
Allow the position of electrostatic ring outlet and wire turn pad not on same shelves, electrostatic ring outlet head is stretched and wraps insulation through absolutely
The breach of edge cushion block, then weld 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
Staggering completely in the position of welding, facilitates welding of outlet and wire turn, raising outlet and the operability of welding position insulating wrapping,
Eliminate safe hidden trouble, improve product quality, it is ensured that the reliability service of product.
As in figure 2 it is shown, be the outlet structure of existing Transformer Winding end electrostatic ring, its electrostatic ring outlet and pad
Between two identical cross-over blocks, gap is little, it has not been convenient to welding and insulating wrapping operate.
Above-described embodiment should not in any way limit the present invention, and the mode of all employing equivalents or equivalency transform obtains
Technical scheme all fall within protection scope of the present invention.
