Technical field
The utility model relates to a kind of coil and machine body structure of transformer, relates in particular to the aluminum foil winding and the machine body structure of amorphous alloy dry-type distribution transformer.
Background technology
The device body of transformer is made up of coil and two big parts unshakable in one's determination, and copper material is a main raw material(s) of making transformer coil.The Copper Product in China resource is very in short supply, relies on import for a long time, just can satisfy the demands.In recent years, international copper valency soared, and the material cost of transformer is risen significantly.
Amorphous alloy dry-type distribution transformer (doing change hereinafter to be referred as amorphous) is the extremely low energy-efficient product of a kind of no-load loss that is widely used.The copper valency rises steadily has influenced the dried cost performance that becomes of amorphous, has also restricted amorphous to a certain extent and has done applying of becoming.
Aluminium is the excellence conductor that electric conductivity is only second to copper, and the mass density of aluminium is little, not as good as 1/3rd of copper.The bauxite resource of China is quite abundant, does not need import.
Existing homemade amorphous is done the low-voltage coil that becomes and nearly all is made into Copper Foil or copper conductor.If replace Copper Foil or copper conductor to make low-voltage coil with aluminium foil, under the identical prerequisite of properties of product, can reduce material cost about 10%.So not only can optimize amorphous and do the cost performance that becomes, and can reduce the rise of copper valency, reduce country's copper resource consumption in short supply the dried influence that becomes this of amorphous.
Summary of the invention
The purpose of this utility model is in order to overcome existing technical deficiency, to provide a kind of and can obviously reduce material cost, and has the aluminum foil winding and the machine body structure of the amorphous alloy dry-type distribution transformer of good energy-saving effect.
The technical solution adopted in the utility model is for achieving the above object: a kind of aluminum foil winding of amorphous alloy dry-type distribution transformer and machine body structure, comprise the three-phase amorphous alloy core, be sleeved on high-voltage coil and low-voltage coil on the core limb, be located at the upper clamping piece of high-voltage coil and low-voltage coil upper end, also comprise the insulation framework that is sleeved on the core limb and somely be fixed on aluminum bronze transition joint on the upper clamping piece by insulated conductor folder or insulator.The electric conducting material of described low-voltage coil is aluminium foil and directly is wound on the insulation framework, the head of described low-voltage coil, end are fixedlyed connected with the aluminum bronze transition joint respectively, and described high-tension coil is copper conductor coiling and with epoxy resin enclosed coil and be sleeved on the outside of low-voltage coil.
The aluminum foil winding of above-mentioned amorphous alloy dry-type distribution transformer and machine body structure, wherein, described insulation framework is the rectangle cylindrical shell with the core limb cross-sections match.
The aluminum foil winding of above-mentioned amorphous alloy dry-type distribution transformer and machine body structure, wherein, described aluminum bronze transition joint is totally six and arrange with the homoaxial form of high-voltage coil and low-voltage coil of two of every phases, every aluminum bronze transition joint is made of integrally welded copper bar and aluminium row, and the head of described low-voltage coil, terminal row with the aluminium of aluminum bronze transition joint are respectively welded.
The aluminum foil winding of above-mentioned amorphous alloy dry-type distribution transformer and machine body structure, wherein, described insulated conductor folder is between the copper bar and upper clamping piece on transition joint top.
The utility model has the advantages that no-load loss is low, no-load current is little, has good energy-saving effect; The solid compact and reasonable of machine body structure, the mechanical Strength for Winding height, the impact that can bear short circuit current is simultaneously because the protective action of insulation framework, can eliminate the influence of the coil that electric power the produced extruding amorphous alloy core of short circuit current, have constant good magnetic performance to guarantee iron core.In addition, this programme has also that the cost of material is low, and is in light weight, reduces the copper valency and goes up to the dried advantages such as influence that become this of amorphous.
