Description
Technical field:
The utility model relates to a kind of winding conducting wire.Particularly a kind of dry reactor aluminium stranded conductor.
Background technology:
In the national grid project of transmitting and converting electricity, the winding of various types of reactors and High-Voltage Electrical Appliances must tolerate higher voltage, also will reduce the loss of electric energy simultaneously.
Coil for the dry reactor that uses in the national grid project of transmitting and converting electricity, tradition is used all is sub-thread multiple conducting wires and around forming, because the coil diameter of dry reactor is very big, the conductor length that needs reaches several kms, like this and around after coil in, the wrapped diameter difference in each the adjacent inboard of circle and the outside can arrive the width of 2 diameters of wire; After the coiling multilayer, the length of each root lead, resistance will differ bigger.The magnetic leakage of generation in service is logical, produces eddy current in lead, causes bigger electric energy loss, is unfavorable for energy savings.And owing to be subjected to aluminum conductor itself to exist impurity, defective to be difficult for the restriction of removing, the reactor of general aluminum conductor coiling only is used for the electrical network less than 66KV, is not suitable for superhigh pressure and ultra high voltage field.
The dry reactor coil that also has adopts by many round aluminum steels are stranded and forms the coiling of rectangle twisted wire, and it is stranded that this rectangle twisted wire adopts aluminium matter to justify bare wire, and skin is wrapped in interior dielectric film successively, the composite insulation structure of insulating barrier and external insulation film.When this insulation aluminium stranded conductor is used for reactor, be only applicable to common high-voltage fence; In service, because the single resistance phase of lead missionary society produces eddy current, thereby circulation forms loss in lead.In addition, the impurity defect that aluminium matter circle bare wire self exists is difficult to avoid, and causes discharge in high pressure easily, has accidents caused drawback.
Summary of the invention:
The utility model aims to provide a kind of dry reactor aluminium stranded conductor.Use the coil of the utility model coiling to replace copper material, be used for superhigh pressure and ultra high voltage field, and can effectively reduce the eddy current loss in the coil, save the energy with aluminium.
The technical solution of the utility model:
The utility model comprises the flat transposed conductor, thin dielectric film and composite insulation layer; The serve as reasons many transposition rectangle twisted wire of the dual layer arrangement that the zero defect sub-thread circle aluminum steel that has the insulation film lapping layer constitutes of described flat transposed conductor; Described thin dielectric film is the insulation film lapping layer; Described composite insulation layer is the compound nonwoven cloth lapping layer that has insulation film; Thin dielectric film is coated on flat transposed conductor outside, and composite insulation layer is coated on the thin dielectric film outside; As shown in Figure 1.
Thin dielectric film described in the utility model, composite insulation layer and the used insulation film of insulation film lapping layer can adopt polyester resin film or polyimide film.
Thin dielectric film described in the utility model, composite insulation layer and insulation film lapping layer can be the half-stack package coating of multi-layer insulation film;
Operation principles of the present utility model and good effect
1, because being the many zero defect sub-threads that have the insulation film lapping layer, flat transposed conductor of the present utility model justifies the transposition rectangle twisted wire of the dual layer arrangement of aluminum steel formation.The every round aluminum steel that constitutes the flat transposed conductor all passes through nondestructive inspection, is high-quality zero defect sub-thread circle aluminum steel, the safety when having guaranteed to be used for superhigh pressure and extra-high voltage grid.
2, because in the flat transposed conductor of the present utility model, the every wrapped round aluminum steel of film is in certain pitch, according to the position of same angular transformation in the flat transposed conductor, mutually strand and, the lenticular wire of dual layer arrangement, when the utility model is used for coil winding, the general employing stood around form, therefore, and in the coil after the coiling, the every wrapped round aluminum steel of film is constantly shifted one's position between internal layer and skin, remedied the wrapped round aluminum steel of each root film owing to be positioned at the difference of the formed length of coil different-diameter, made that the every wrapped round aluminum steel length of film is equal substantially, avoided and reduced owing to the different eddy current losses that produce of coil inside conductor length; After tested, the balanced ratio of resistance of the present utility model is less than 1.2%, compares the eddy current loss more than 70% that can reduce coil with the coil of ordinary lines coiling the in service of coil.
3, because flat transposed conductor of the present utility model adopts the zero defect sub-thread circle aluminum steel that has the insulation film lapping layer, all adopt insulation film wrapped to every round aluminum steel, make every round aluminum steel mutually insulated; And thin dielectric film is coated on flat transposed conductor outside, and composite insulation layer is coated on the thin dielectric film outside; Improved proof voltage grade of the present utility model; After tested more than the average withstand voltage 10000V of the utility model, more than the puncture voltage 26000V; Therefore, the utility model can enter superhigh pressure and ultra high voltage field.
4, the utility model adopts with aluminium and replaces copper material, makes the winding conducting wire of superhigh pressure and ultra high voltage field reactor and High-Voltage Electrical Appliances, has saved China's copper resource very in short supply, meets the national conditions of the rich aluminium of the poor copper of China.And the price of aluminium only is a copper 1/4, along with the application of this product, can reduce the construction cost of China's electrical network significantly, helps fast development of national economy.
In sum, the utility model is a kind of dry reactor aluminium stranded conductor.Use the coil of the utility model coiling to replace copper material, be used for superhigh pressure and ultra high voltage field, and can reduce the eddy current loss in the coil, save the energy with aluminium.
