Abstract: A transformer cooling system is described. The transformer cooling system includes a dry transformer and a housing for the dry transformer. The dry transformer includes a core including a leg. Additionally, the dry transformer includes a winding body arranged around the leg. Further, a cooling channel extending in a direction of a longitudinal axis of the winding body is provided. Additionally, the transformer cooling system includes a heat exchanger adapted to dissipate heat from the housing. Further, the transformer cooling system includes a flow generating device arranged in the housing for providing a cooling flow in the cooling channel. The flow generating device is connected to the heat exchanger.

Abstract: A transformer is disclosed. The transformer includes a first coil including a first stack of wire disks stacked in a first direction; an exterior barrier arranged to form a first air gap between outer sides of the wire disks of the first stack of wire disks and the exterior barrier; an interior barrier arranged to form a second air gap between inner sides of the wire disks of the first stack of wire disks and the interior barrier; a wind generator arranged to generate an air flow in the first direction; a core in the form of a cylinder that is surrounded by the first coil; and an air guiding plate fixed to one of the exterior barrier and the interior barrier, to guide the air flow in a second direction along first stack gaps between the wire disks of the first stack of wire disks. The transformer effectively improves the heat dissipation of the coil and thus allows a smaller transformer in size.
