Abstract
The utility model discloses a kind of novel 500kV auto-transformer common winding outlet structures, lift one's head including common winding, pressing ring, common winding, series coil, series coil static board, through-hole is offered on series coil static board, common winding is lifted one's head through the through-hole outlet on series coil static board.The structure design of the utility model can not carry out aperture or fluting to body pressing ring, reach and guarantee pressing ring integrality, improve transformer anti-short circuit capability.And the design scheme of the utility model is to open up through-hole on original series coil static board and realize, not only ensure that pressing ring intensity, but also reduce manufacturing process.
Description
Technical field
The utility model relates to a kind of novel 500kV auto-transformer common winding outlet structures, belong to the production of transformer class
Product manufacturing technology.
Background technique
With power network development, 500kV power grid becomes most important power grid.The anti-short circuit capability pair of 500kV auto-transformer
Power grid security plays an important role.The pressing ring intensity of transformer plays the role of its anti-coil axial direction short-circuit force conclusive.It passes
The design common winding head end outlet of system slackens pressing ring intensity by pressing ring aperture or pressing ring fluting outlet structure.
Utility model content
Against the above deficiency, the utility model provides a kind of novel 500kV auto-transformer that can increase pressing ring intensity
Common winding outlet structure.It is public using the 500kV auto-transformer of positive and negative tune switch that present design is suitable for tap switch
Coil outlet structure.
The utility model adopts the technical scheme that a kind of novel 500kV auto-transformer in order to solve problem above
Common winding outlet structure, including common winding, pressing ring, common winding are lifted one's head, series coil, series coil static board, it is special
Sign is, through-hole is offered on series coil static board, and common winding is lifted one's head to be gone out by the through-hole on series coil static board
Line.
The utility model has the advantages that the structure design of the utility model can not carry out aperture or fluting to body pressing ring, reach guarantee
Pressing ring integrality improves transformer anti-short circuit capability.And the design scheme of the utility model is in original series coil electrostatic
Through-hole is opened up on plate and is realized, not only ensure that pressing ring intensity, but also reduce manufacturing process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the utility model provides a kind of novel 500kV auto-transformer common winding outlet structure, packet
It includes common winding 1, pressing ring 2, common winding to lift one's head 3, series coil 4, series coil static board 5, on series coil static board 5
Through-hole 6 is offered, common winding lifts one's head 3 by 6 outlet of through-hole on series coil static board 5.
The above descriptions are merely preferred embodiments of the present invention, is not restricted to the utility model, for ability
For the technical staff in domain, various modifications and changes may be made to the present invention.It is all the spirit and principles of the utility model it
Interior, any modification, equivalent replacement, improvement and so on should be included within the scope of the claims of the utility model.
