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 for the PET film alclad composite conductor in SF6 gas-insulated transformer, belong to transformer technology field.
Background technology
At present, transformer is mainly to two aspect development: one is to the development of super-huge superhigh pressure aspect, and another is to energy-saving, miniaturization, low noise, high impedance, explosion-proof type development.The former is generally used in large-scale power station or electric power conveying; The latter is mainly based on middle-size and small-size product.Along with the Development of Urbanization of 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 Copacity oil-filled transformer oil mass is large, once catch fire because of fault, forms serious threat by the security of the lives and property of skyscraper and people.Therefore, people are to the investigation and application also pay attention to day by day not firing transformer.Do not fire transformer different by its dielectric, be divided into silicon transformer, poured with epoxy resin transformer, multiple quick dielectric medium transformer and SF6 gas-insulated transformer.Also apply at present seldom at China SF6 gas-insulated transformer, SF6 gas-insulated transformer winding wire leans on import substantially, expensive.
Summary of the invention
The object of the invention is to overcome the deficiency existed in prior art, thus a kind of high temperature resistant, proof voltage, mechanical strength are good, heat conductivity is good SF6 gas-insulated transformer winding wire-PET film alclad composite conductor is provided.
According to technical scheme provided by the invention, described SF6 gas-insulated transformer winding wire-PET film alclad composite conductor, comprises flat aluminium wire conductor, the PET film insulating barrier of single flat aluminium wire, the PET film insulating barrier of aluminium composite conductor; By the overlapping wrapped PET film insulating barrier being configured to single flat aluminium wire of single-layer PET film strip outside described flat aluminium wire conductor; Again by the overlapping wrapped PET film insulating barrier forming aluminium composite conductor of multilayer PET film strip outside the PET film insulating barrier of described single flat aluminium wire.
The width of described flat aluminium wire conductor is 9.95mm ~ 10.05mm, and thickness is 2.96 ~ 3.02mm.
The thickness of described PET film band is 0.045 ~ 0.055mm.
The PET film insulating barrier of described single flat aluminium wire, the PET film insulating barrier of described aluminium composite conductor form by PET film band is overlapping wrapped; Its overlapping wrapped lap width is 2mm ~ 4mm.
The thickness of the PET film insulating barrier of described single flat aluminium wire is 0.21 ~ 0.29mm; The thickness of the PET film insulating barrier of aluminium composite conductor is 0.82 ~ 0.94mm.
The present invention adopts the plastic film with the high seal of very high mechanical properties and insulating capacity as insulating material; The PET film alclad composite conductor made is high temperature resistant, proof voltage, mechanical strength are good, heat conductivity is good.
Accompanying drawing explanation
Fig. 1 is cross sectional representation of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, the present invention is formed primarily of parts such as the PET film insulating barrier 2 of flat aluminium wire conductor 1, single flat aluminium wire, the PET film insulating barriers 3 of aluminium composite conductor.
Between high-low pressure winding, winding over the ground between the dielectric strength of main insulation depend mainly on the dielectric strength of SF6 gas, and the uniformity degree of dependence of SF6 to electric field is very high, therefore strictly to control the electric field strength in gas, adopt the plastic film with the high seal of very high mechanical properties and insulating capacity as insulating material.
During production, flat aluminium wire conductor 1 is shaping through extrusion equipment by specification, by the overlapping wrapped PET film insulating barrier 2 being configured to single flat aluminium wire of single-layer PET film strip outside described flat aluminium wire conductor 1; Again by the overlapping wrapped PET film insulating barrier 3 forming aluminium composite conductor of multilayer PET film strip outside the PET film insulating barrier 2 of described single flat aluminium wire.
The width of described flat aluminium wire conductor 1 is 9.95mm ~ 10.05mm, and thickness is 2.96 ~ 3.02mm.
The thickness of described PET film band is 0.045 ~ 0.055mm.
The PET film insulating barrier 2 of described single flat aluminium wire, the PET film insulating barrier 3 of described aluminium composite conductor form by PET film band is overlapping wrapped; Its overlapping wrapped lap width is 2mm ~ 4mm.
The thickness of the PET film insulating barrier 2 of described single flat aluminium wire is 0.21 ~ 0.29mm; The thickness of the PET film insulating barrier 3 of aluminium composite conductor is 0.82 ~ 0.94mm.
The present invention can be used for SF6 gas-insulated transformer winding wire, and PET film alclad composite conductor is high temperature resistant, proof voltage, mechanical strength are good, heat conductivity is good.
