Abstract
The invention relates to a winding wire (PET film and aluminum combined wire) for an SF6 gas insulated transformer, which comprises aluminum flat wire conductors, PET film insulated layers of individual aluminum flat wires, PET film insulated layers of aluminum combined wires; individual PET film bands outside the aluminum flat wire conductors are overlapped and wound to form the PET film insulated layers of the individual aluminum flat wires; and a plurality of layers of PET film band outside the PET film insulated layers of the individual aluminum flat wires are overlapped and wound to form the PET film insulated layers of the aluminum combined wires. According to the invention, plastic films with very high mechanical intensity, insulation capacity and high sealing performance serve as an insulation material, and the PET film and aluminum combined wire made of the insulation material is anti-high temperature, voltage resistant and good in mechanical intensity and heat conduction performance.
Description
Technical field
The invention discloses SF6 gas-insulated transformer winding wire, specifically be used for the PET film alclad composite conductor of SF6 gas-insulated transformer, belong 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.It is different by its dielectric not fire transformer, is divided into silicon transformer, poured with epoxy resin transformer, multiple quick dielectric medium transformer and SF6 gas-insulated transformer.Use also seldom at present at China SF6 gas-insulated transformer, the SF6 gas-insulated transformer leans on import basically with winding wire, and is expensive.
Summary of the invention
The object of the invention is to overcome the deficiency that exists in the prior art, thereby provide a kind of high temperature resistant, proof voltage, mechanical strength is good, heat conductivity is good SF6 gas-insulated transformer with winding wire-PET film alclad composite conductor.
According to technical scheme provided by the invention, described SF6 gas-insulated transformer comprises the PET thin dielectric film of flat aluminium wire conductor, single flat aluminium wire, the PET thin dielectric film of aluminium composite conductor with winding wire-PET film alclad composite conductor; Described flat aluminium wire conductor outside is by the overlapping wrapped PET thin dielectric film that constitutes single flat aluminium wire of single-layer PET film strip; The PET thin dielectric film outside of described single flat aluminium wire is again by the overlapping wrapped PET thin dielectric film that consists of the aluminium composite conductor of multilayer PET film strip.
The width of described flat aluminium wire conductor is 9.95mm～10.05mm, and thickness is 2.96 ~ 3.02mm.
