Abstract
The utility model discloses a three-dimensional coil iron core oil-immersed type transformer with a high-voltage coil lead being output in a concealed mode. The three-dimensional coil iron core oil-immersed type transformer comprises a high-voltage lead, the high-voltage lead is flatly laid on the surface of a high-voltage coil from the coil winding lead position and led out from an upper end face of the high-voltage coil, insulating gummed paper is arranged on the inner surface and the outer surface of the high-voltage lead, the high-voltage lead is distributed at the upper end of the high-voltage coil side by side, welding points of the high-voltage lead are arranged at the upper end of high-voltage coil, and the welding points are wrapped by insulating tapes. By means of the three-dimensional coil iron core oil-immersed type transformer, the high-voltage lead hardly occupies space on the outer surface of the coil, the distance between the coil and the tank wall is reduced, the size of an oil tank is further reduced, and cost is saved.
Description
Technical field
The utility model relates to a kind of three-dimensional winding iron core oil and invades the formula transformer, and the three-dimensional winding iron core oil of the specifically hidden outlet of a kind of high-tension coil lead-in wire is invaded the formula transformer.
Background technology
The three-dimensional winding iron core oil of transformer production manufacturer production is invaded the formula transformer now, high-voltage connection is all drawn from coil surface, as Fig. 1, in Fig. 1, the 11st, high-voltage connection, the 12nd, coil winding go out lead-in wire place, the 13rd, high-tension coil, the 14th, the pad wrap insulate place, the 17th of high-voltage connection, folder, the 18th, fuel tank tank wall.After drawing from high-tension coil 13 surfaces, high-voltage connection 11 carries out again the outside lead welding, draw from the cable guide of folder 17 after wrap insulate, the shortcoming of this outside lead is: will increase the distance of coil to fuel tank tank wall 18 during the design fuel tank, in order to lead-in wire is in safe range to the distance of tank wall, thereby increased the fuel tank volume, improved cost.
Summary of the invention
The problem that exists in order to overcome prior art, the purpose of this utility model is to provide the three-dimensional winding iron core oil of the hidden outlet of a kind of high-tension coil lead-in wire and invades the formula transformer, after adopting the utility model, high-voltage connection takes up room hardly at the coil outer surface, reduced the distance of coil to tank wall, thereby reduced the fuel tank volume, provided cost savings.
The purpose of this utility model is achieved through the following technical solutions:
The three-dimensional winding iron core oil of the hidden outlet of a kind of high-tension coil lead-in wire is invaded the formula transformer, comprises high-voltage connection, and it is characterized in that: this high-voltage connection goes out the lead-in wire place by coil winding and is tiled in the high-tension coil surface, and from the high-tension coil upper surface, draws; Be provided with the insulation gummed paper at the high-voltage connection surfaces externally and internally; High-voltage connection is arranged side by side in the high-tension coil upper end, and the pad of high-voltage connection is positioned at the upper end of high-tension coil, and at pad place wrap insulate band.
In the utility model, high-voltage connection passes from the high-tension coil surface, and from space, high-tension coil end, draws.Be equipped with three-layer insulated gummed paper at the high-voltage connection surfaces externally and internally.
The utility model has realized that a kind of brand-new three-dimensional winding iron core oil invades that the formula high-voltage lead of transformer is hidden goes out collimation method, pass through the utility model, avoid the horizontal space of coil, the coil outer surface without the lead-in wire outlet, but hidden from coil surface, passing, then draw from the end winding space, do not take the coil axial space.Can reduce the distance of coil to tank wall during the design fuel tank.
After adopting the hidden outlet of the utility model high-voltage connection, high-voltage connection takes up room hardly at the coil outer surface, with traditional lead-in wire, arranges and compares, and has reduced the distance of coil to tank wall, thereby has reduced the fuel tank volume, has saved the cost of wet goods material.

Embodiment
The three-dimensional winding iron core oil of the hidden outlet of a kind of high-tension coil lead-in wire described in the utility model is invaded the formula transformer, see Fig. 2 and Fig. 3, this transformer comprises high-voltage connection 1, this high-voltage connection goes out lead-in wire place 2 by coil winding and is tiled in high-tension coil 3 surfaces, pass from the high-tension coil surface, and from the cable guide of high-tension coil upper surface folder 7, draw; Be provided with three-layer insulated gummed paper 4 at the high-voltage connection surfaces externally and internally; High-voltage connection is arranged side by side in the high-tension coil upper end, and the pad 5 of high-voltage connection is positioned at the upper end of high-tension coil, and at pad place wrap insulate band 6.
The utility model has realized that a kind of brand-new three-dimensional winding iron core oil invades that the formula high-voltage lead of transformer is hidden goes out collimation method, pass through the utility model, avoid the horizontal space of coil, the coil outer surface without the lead-in wire outlet, but hidden from coil surface, passing, then draw from the end winding space, do not take the coil axial space.Can reduce the distance of coil to fuel tank tank wall 8 during the design fuel tank, thereby reduce the fuel tank volume, save the cost of wet goods material.
