Oil flow guide member for oil-cooled electrical equipment - has wedge-formed tongue to produce equal oil flow in all radial flow channels

摘要

The guide member has a downwardly-directed wedge-formed tongue, the side of which facing away from the winding makes good contact with the surface of the insulating cylinder facing the winding. The other surface of the tongue, the surface facing the winding, will have a downwardly increasing distance from the winding. This causes the upwardly-directed oil flow between the winding and the insulating cylinder to have an increasingly more narrow flow path during its upward movement. The oil flow is therefore forced to move partly in a radial direction in between the discs or the layers in the winding.
