L-shaped it is long while and connection L-shaped short side and two connection sides during long L-shaped, kink 13 respectively with the first cornerite portion 11 and second
The long side connection of L-shaped in cornerite portion 12.
Kink 13 is also L-shaped structure, including:Orthogonal first end and the second end.By L-shaped accommodating chamber parcel around
Two adjacent angles in group, therefore the first end length of kink 13 and the second end length, determine and are provided with corner wrapping device 1
Insulation distance between winding 15 and adjacent winding 15.Can be according to different electric insulation requirements or different insulation distances
It is required that, determine the first end length and the second end length of kink 13.
In the embodiment of the present invention, the winding 15 of transformer is regular rectangular parallelepiped structure, when corner wrapping device 1 is arranged at transformation
When on the winding 15 of device, the first plane of winding 15 is closed in the first cornerite portion 11, and the second cornerite portion 12 closes on the second of winding 15
Plane, the first plane is relative with the second plane, and is parallel to each other, so the first cornerite portion 11 and the second cornerite portion 12 are mutually flat
OK.
The first end of kink 13 is mutually perpendicular to the second end, and kink 13 is perpendicular to the first cornerite portion 11, bending
Portion 13 is perpendicular to the second cornerite portion 12.
Kink 13, the first cornerite portion 11 and the second cornerite portion 12 form a L-shaped accommodating chamber, are wrapped up by L-shaped accommodating chamber
Two adjacent angles in the winding 15 of transformer, and corner wrapping device 1 is insulating materials support, and cornerite is provided with so as to ensure that
Insulation distance between the winding 15 of device 1 and adjacent winding 15 is larger so that have between the winding 15 of adjacent transformer
There is preferable insulation effect.
With continued reference to Fig. 4, there is provided a kind of transformer, the transformer bag for the another aspect of the foundation embodiment of the present invention
Include:Insulation spacer 16 and multiple windings 15, and the corner wrapping device 1 that above-described embodiment is provided;
