OIL-FILLED TRANSFORMER SWITCHING FRAME

摘要

An oil-filled transformer switching frame is disclosed which includes at least one longitudinal channel element that is essentially formed by a wall that is curved in a U-shaped manner, for receiving in its inner region stranded conductors of an oil tank of an oil transformer. The wall of the channel element can include a first layer of mechanically strong, planar insulating material and a second layer of mechanically strong, planar insulating material that is adjacent to and fundamentally parallel to said first layer, the first layer and the second layer being connected to and spaced apart by a third layer of a mechanically strong, corrugated insulating material having hollow spaces that can be flooded with a fluid by way of lateral edges.

1. An oil-filled transformer switching frame, comprising:
at least one longitudinal channel element that is essentially formed by a wall that is curved in a U-shaped manner, said channel element being configured for receiving stranded conductors of an oil tank of an oil transformer in an inner region of said channel element, said inner region being defined by the wall; a first layer of the wall of the channel element being formed of mechanically strong, planar insulating material; a second layer of the wall of the channel element being formed of mechanically strong, planar insulating material that is adjacent to and fundamentally parallel to said first layer; and a third layer, said first layer and said second layer being connected to and spaced apart by the third layer of a mechanically strong, corrugated insulating material that is arranged between said first layer and said second layer, wherein the third layer includes lateral edges and is corrugated such that the hollow spaces are formed by the corrugated shape that can be flooded with a fluid by way of the lateral edges.
