Put the armature winding on roll and secondary windings, and insert roll formation magnetic circuit at least two
Magnetic core forms, as being made up of two U-shaped magnetic cores or a U-shaped magnetic core and an I shape magnetic core.
In correlation technique, the commonly used structure of transformator is armature winding, the coaxial level of secondary windings
Proximally it is arranged in the both sides of an insulator, and typically armature winding and secondary windings level phase
Closely it is configured in the same arm of U-shaped magnetic core, this coiling magnetic core arm and another magnetic core arm, and two
Connecting portion between arm constitutes magnetic loop required during transformator work.
Specifically, as it is shown in figure 1, transformator 100 includes U-shaped magnetic core 102 and U-shaped magnetic core
104, armature winding 106 is wrapped on a sidewall of U-shaped magnetic core 104, and secondary windings 108 twines
It is wound on a sidewall of U-shaped magnetic core 102, and is wound with armature winding on U-shaped magnetic core 104
The sidewall of 106 is relative with the sidewall being wound with secondary windings 108 on U-shaped magnetic core 102.Meanwhile,
Owing to armature winding 106 and secondary windings 108 are that coaxial level proximally configures, therefore to
Realize the good coupling between armature winding 106 and secondary windings 108, it is necessary to armature winding 106
The radial direction number of turn increase, and axially the number of turn reduces, the radial windings that the most whole armature winding 106 is formed
The number of plies is many, and axial winding length is short；Similarly, it is desired to the radial direction number of turn of secondary windings 108 increases,
And axially the number of turn reduces, the radial windings number of plies that the most whole secondary windings 108 is formed is many, axial winding
Length is short, thus easily causes the problem that transformator heat radiation is bad.Additionally due to the radial windings number of plies is relatively
Many, the wire rod of more consumption is therefore needed when identical winding turns, material cost is relatively big, and
The radial direction number of plies of armature winding 106 and secondary windings 108 is many, also increases the entirety of transformator 100
Size.
Therefore, how to guarantee that the degree of coupling between the armature winding in transformator and secondary windings is constant
Under premise, reduce the production cost of transformator, optimize the skill that transformator radiating effect becomes urgently to be resolved hurrily
Art problem.
Summary of the invention
It is contemplated that at least solve one of technical problem present in prior art or correlation technique.
To this end, it is an object of the invention to propose a kind of armature winding and secondary windings in axial and footpath
