Abstract
The utility model discloses an angle ring structure for an end part of a 10kV oil-immersed transformer, and relates to the technical field of transformers. The structure comprises angle rings, a high-voltage coil, and a low-voltage coil, wherein end parts of the high-voltage and low-voltage coils are provided with the angle rings, and the angle rings are shaped like L. One side of each angle ring is plugged between the end parts of the high-voltage and low-voltage coils, and the other sides of the angle rings are exposed outside the end parts of the high-voltage and low-voltage coils and covers two end faces of the high-voltage coil. The structure provided by the utility model reduces the size of an end insulating structure, reduces the cost, greatly prolongs the service life of a transformer, and is stable in operation.
Description
Technical field
The utility model relates to transformer technology field, be specifically related to a kind of 10kV oil-filled transformer end and add square ring structure.
Background technology
10kV oil-filled transformer be in, the conventional a kind of static electric equipment of small enterprise, its simple structure, operational reliability is higher, is with rated load continuously-running 20～25 years under rated condition.Traditional 10kV oil-filled transformer does not adopt square ring when design, and overhang insulation physical dimension is large, and cost is high, has greatly increased operating cost.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to be to provide a kind of 10kV oil-filled transformer end to add square ring structure, has reduced overhang insulation physical dimension, and cost has improved the working life of transformer greatly, reliable.
To achieve these goals, the utility model is to realize by the following technical solutions: 10kV oil-filled transformer end adds square ring structure, comprise square ring, high-tension coil and low-voltage coil, high-tension coil and low-voltage coil end are provided with square ring, square ring is L-type, one side of square ring is plugged between high-tension coil and low-voltage coil end, and square ring another side is exposed at outside, end, covers high-tension coil both ends of the surface.
According to above-mentioned 10kV oil-filled transformer end, add square ring structure, wherein, described square ring is compound mylar square ring.
The beneficial effects of the utility model: reduced overhang insulation physical dimension, cost, has improved the working life of transformer greatly, reliable.
Accompanying drawing explanation
