The present utility model relates to a winding wire for an SF6 gas insulation transformer, that is, a PET film aluminum-clad combined conducting wire. The wire comprises an aluminum flat wire conductor, a PET thin film insulation layer of a single aluminum flat wire, a PET thin film insulation layer of an aluminum combined conducting wire; the PET thin film insulation layer of the single aluminum flat wire is formed by overlapping and wrapping a single layer of PET thin film belt outside the aluminum flat wire conductor; and the PET thin film insulation layer of the aluminum combined conducting wire is formed by overlapping and wrapping multiple layers of PET thin film belts outside the PET thin film insulation layer of the single aluminum flat wire. High leak-proof plastic films of high mechanical strength and insulation capability are adopted as insulation materials; and the manufactured PET film aluminum-clad combined conducting wire is high temperature resistant and voltage resistant, and has good mechanical strength and heat conductivity.
Description
Technical field
The utility model discloses SF
6The gas-insulated transformer winding wire specifically is used for SF
6PET film alclad composite conductor in the gas-insulated transformer belongs to the transformer technology field.
Background technology
At present, transformer is mainly to two aspect development: the one, and to the development of super-huge superhigh pressure aspect, another is to energy-saving, miniaturization, low noise, high impedance, explosion-proof type development.The former generally is used in large-scale power station or electric power and carries; The latter is mainly take middle-size and small-size product as main.Development of Urbanization along with China, big city population is more intensive, skyscraper stands in great numbers, power consumption sharply increases, number transformer is also in continuous increase, traditional large capacity oil-filled transformer oil mass is large, in case barrier catches fire for some reason, will consist of serious threat to skyscraper and people's the security of the lives and property.Therefore, people are to the research of not firing transformer with use also pay attention to day by day.Do not fire transformer different by its dielectric, be divided into silicon transformer, poured with epoxy resin transformer, multiple quick dielectric medium transformer and SF
6Gas-insulated transformer.At China SF
6Gas-insulated transformer is used also seldom at present, SF
6Gas-insulated transformer leans on import basically with winding wire, and is expensive.
