Abstract
The utility model relates to a transformer 500kV pin configuration belongs to transformer equipment technical field. Technical scheme is: contain oil tank wall (1), square ring (2), 500kV go between (4) and ring flange (7), the opening part of oil tank wall (1) is equipped with 500kV lead wire (4), trompil department inboard fixed square ring (2) of oil tank wall (1), the trompil department outside mounting flange dish (7) of oil tank wall (1), ring flange (7) and oil tank wall (1) contact side are equipped with the blind hole of fixed square ring (2), the internal diameter lateral root portion of ring flange (7) just is equipped with fillet R near the arris of square ring (2), fillet R >= 45 degrees. The beneficial effects of the utility model are that: at the fixed ring flange that is equipped with the fillet in the trompil department outside of oil tank wall, improve ring flange root electric field, replace traditional coupling and electrostatic ring, simple structure, preparation, simple to operate practice thrift the cost.
Description
Technical field
The utility model relates to a kind of transformer 500kV pin configuration, and especially 500kV level transformer 500kV pin configuration, belongs to technical field of transformer equipment.
Background technology
With reference to accompanying drawing 2, conventional 500kV level transformer 500kV pin configuration comprises oil tank wall, square ring, electrostatic ring, 500kV lead-in wire, pipe joint and nut, weld square ring inside oil tank wall, oil tank wall outside weldings pipe joint, pipe joint forms wedge angle at oil tank wall tapping, when 500kV lead-in wire passes through, sharp corner can produce high electric field strength, and having to increases electrostatic ring and square ring to improve the electric field of sharp corner, the 500kV pin configuration of this routine, complex structure, cost is high.
Utility model content
The utility model object is to provide a kind of transformer 500kV pin configuration, is fixed with the ring flange of fillet outside the tapping of oil tank wall, improves ring flange root electric field, replaces traditional pipe joint and electrostatic ring, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of transformer 500kV pin configuration, comprise oil tank wall, square ring, 500kV lead-in wire and ring flange, the opening part of oil tank wall is provided with 500kV lead-in wire, square ring is fixed inside the tapping of oil tank wall, fixed flange outside the tapping of oil tank wall, ring flange and oil tank wall contact side are provided with the blind hole of fixing square ring, the internal side diameter root of ring flange and arris near square ring is provided with fillet R, fillet R >=45 degree.
The internal side diameter root of described ring flange and be 45 degree near the fillet R of the arris of square ring.
The internal side diameter root of ring flange and fillet R on the arris of square ring, can improve the electric field of ring flange root.
The beneficial effects of the utility model are: the ring flange being fixed with fillet outside the tapping of oil tank wall, improve ring flange root electric field, replace traditional pipe joint and electrostatic ring, and structure is simple, make, easy for installation, cost-saving.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is background technology structural representation;
In figure: oil tank wall 1, square ring 2, electrostatic ring 3,500kV lead-in wire 4, pipe joint 5, nut 6, ring flange 7.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of transformer 500kV pin configuration, comprise oil tank wall 1, square ring 2,500kV lead-in wire 4 and ring flange 7, the opening part of oil tank wall 1 is provided with 500kV lead-in wire 4, fix square ring 2 inside the tapping of oil tank wall 1, fixed flange 7 outside the tapping of oil tank wall 1, ring flange 7 and oil tank wall 1 contact side are provided with the blind hole of fixing square ring 2, the internal side diameter root of ring flange 7 and arris near square ring 2 is provided with fillet R, fillet R >=45 degree.
In the present embodiment, transformer is 500kV level transformer, the internal side diameter root of ring flange 7 and fillet R on the arris of square ring 2 is 45 degree, can improve the electric field of ring flange 7 root.
Compared with traditional 500kV level transformer 500kV pin configuration, eliminate electrostatic ring 3, pipe joint 5 and nut 6, structure is simple, makes, easy for installation, cost-saving.
