It must can be contracted through the respective lead of the manhole and Long Circle through hole to the air line distance the mounting hole
Subtract, and maximum can reduce above-mentioned relative to the increased insulation distance length of prior art, draw so as to reduce lead and tap
Line can reduce size of the fuel tank in its width to the electrical distance of the ironwares such as folder, so as to reduce the volume of fuel tank
With weight, and then reduce the volume and weight of transformer to a certain extent, and then be easy to the transhipment and installation of transformer.
The quantity of the Long Circle through hole and manhole is respectively one, and described manhole is located at the Long Circle
On the length direction of through hole.
The quantity of the mounting hole is one, and the mounting hole is through hole.
Described mounting hole, Long Circle through hole and manhole distribution triangular in shape.
Described fixed plate uses insulating board.
The span that the stepped portions are higher by the height of fixed plate corresponding side in the part of fixed plate corresponding side is
5mm-10mm。
Compared with prior art, the utility model has the advantage of：
Oil-filled transformer lead's insulation support described in the utility model includes the fixed plate that its one end carries stage portion,
And from the side, fixed plate of the end with stage portion is integrally T-shaped, and lead and tap are drawn in the use of T stage stage structure
The circuit journey broken line type that shown air line distance is converted in the utility model from the prior art of climbing of line climbs circuit journey, so that
The electrical distance of lead and tap lead to ironwares such as folders can be reduced, i.e., can reduce size of the fuel tank in its width,
So as to reduce the volume and weight of fuel tank, and then reduce the volume and weight of transformer to a certain extent, and then be easy to transformation
The transhipment and installation of device, and the production cost of transformer can also be reduced to a certain extent.
As can be seen here, the utility model compared with prior art, with substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
