Detailed Description
Example 1
As shown in fig. 1, the spliced aluminum winding is formed by sequentially connecting circular prefabricated ceramic aluminum wire turns 1 end to end in a single spiral direction. Each ring-shaped prefabricated ceramic aluminum wire turn 1 has two turns. When the connection is carried out, the ceramic film layer on the surface layer of the annular prefabricated ceramic aluminum wire turns 1 is stripped, and then the two annular prefabricated ceramic aluminum wire turns 1 are connected end to end on the circular transformer insulating cylinder in a welding or other conventional aluminum wire butt joint mode to form a winding. The annular prefabricated ceramic aluminum wire coil 1 is formed by performing thermoelectric chemical oxidation treatment on an aluminum conducting wire which is bent into an annular shape in advance. The thermoelectric chemical oxidation is a prior art, and specifically, refer to a method disclosed in patent CN2022104775920, in which an aluminum lead pre-bent into a circular ring shape is placed into a cylindrical electrode containing an electrolyte, and the aluminum lead and the cylindrical electrode are respectively connected to a thermoelectric oxidation power supply, so that the surface of the aluminum lead is subjected to thermoelectric oxidation to generate a ceramic film.
Example 2
The difference between this embodiment and embodiment 1 is that the prefabricated ceramic aluminum wire turns used are elliptical ring-shaped prefabricated ceramic aluminum wire turns, the cross section of the insulating cylinder is elliptical, and the assembled aluminum winding is an elliptical aluminum winding.
Example 3
The difference between the embodiment and the embodiment 1 is that the prefabricated ceramic aluminum wire turns used are polygonal annular prefabricated ceramic aluminum wire turns, the cross section of the insulating cylinder is polygonal, and the assembled aluminum winding is a polygonal aluminum winding.
Example 4
As shown in fig. 2, a spliced aluminum winding is different from the embodiment 1 in that a circular ring-shaped prefabricated ceramic aluminum wire turn 1 is used as a single-turn wire turn, and an insulating sheath 2 is sleeved on an inter-turn welding position. The insulating sheath 2 is a silica gel sheath. When inter-turn welding is carried out, the insulating sheath 2 is firstly sleeved on the annular prefabricated ceramic aluminum wire turn 1, and after welding, the insulating sheath 2 is moved to a welding position to wrap the welding position.
