Transformers with alternately radially disposed first and second conductors
View Patent ↗A transformer may comprise a winding wrapped around a magnetic core, the winding having at least one winding portion extending between the magnetic core and the exterior of the winding in radial direction. The winding may comprise at least a first conductor and at least a second conductor, arranged radially adjacent to each other in each winding portion with the interposition of an insulating layer, wherein the first conductor is arranged radially inwardly with respect to the second conductor for part of each winding portion length, and radially outwardly with respect to the second conductor for another part of each winding portion length.
1. A transformer comprising:
a winding disposed as wrapped around a magnetic core,
the winding having at least one winding portion extending between a central core disposition and the exterior of the winding in a radial direction,
the winding comprising at least a first conductor and at least a second conductor and an insulating layer, the first and second conductors being arranged radially adjacent to each other in each winding portion with the interposition of the insulating layer,
the first conductor being arranged radially inwardly with respect to the second conductor for part of each winding portion length, and radially outwardly with respect to the second conductor for another part of each winding portion length,
the first conductor being passed at least in part from one side of the second conductor to the other side of the second conductor,
the second conductor being structurally continuous all along the length of each winding portion,
the second conductor comprising a substantially similar width along all the length of each winding portion, and
the first conductor comprising a first intermediate end and a second intermediate end; wherein the first intermediate end and the second intermediate end are conductively connected together by one or more discrete structural connectors in a region protruding beyond the width of the second conductor.
2. A transformer according to claim 1 , wherein the second intermediate end comprises a plurality of holes and the first intermediate end comprises a plurality of fasteners configured to be respectively each fitted into a corresponding one of the plurality of holes.
3. A transformer according to claim 1 , comprising a first socket welded to the first intermediate end and a second socket welded to the second intermediate end, each socket having a first leg, a second leg and one or more bight portions joining the first and second legs to each other.
4. A transformer according to claim 3 , wherein the first and the second sockets are made of Aluminum or Copper.
