Abstract

The invention relates to a flat transposed aluminum conductor with a cooling channel. The flat transposed aluminum conductor comprises a flat transposed aluminum conductor core, cooling channel soft copper pipes, a film insulating layer and a composite insulating layer, wherein the flat transposed aluminum conductor core is sequentially wrapped by the film insulating layer and the composite insulating layer. The flat transposed aluminum conductor core is formed by a plurality of defect-free single-stranded round aluminum wires with insulating film taped coverings, namely the flat transposed aluminum conductor core is a multi-layer arrangement disposed rectangular stranded wire. The cooling channel soft copper pipes are multiple soft copper pipes with insulating film taped coverings, the lengths of the soft copper pipes are the same as the lengths of the round aluminum wires, the diameters of the soft copper pipes are the same as the diameters of the single-stranded round aluminum wires in the flat transposed aluminum conductor core, and the soft copper pipes are transversely arranged in the middle of the flat transposed aluminum conductor core to serve as the channel of cooling liquid. The film insulating layer is an insulating film taped covering. The composite insulating layer is a composite non-woven fabric taped covering with an insulating film. According to the flat transposed aluminum conductor, the cooling liquid can carry out circulating cooling in the cooling channel soft copper pipes inside the flat transposed aluminum conductor to directly cool the winding wires, and the flat transposed aluminum conductor is safe and reliable.

Description

technical field

[0001] The invention relates to a winding wire, in particular to a flat transposition aluminum conductor with a cooling channel. Background technique

[0002] At present, ordinary flat transposed aluminum conductors have been successfully applied in ultra-high voltage and ultra-high voltage grid reactors, and have been operating well; but in the operation of the grid, reactors and transformers are often in full load and overload operation. It is easy to cause the temperature rise of the winding in the reactor and the transformer to be too high; especially the high voltage and high current impact caused by various disasters in the power grid can easily cause the reactor and the transformer to reach a very high temperature instantly, which affects the power supply efficiency of the power grid and safe.

[0003] Therefore, on the basis of existing technologies, how to continuously develop new products to meet the needs of the market, so as to ensure that the pr...
