Technical field
The utility model relates to a kind of electromagnetic wire application technology, and particularly a kind of wrapped round aluminum steel of film that is used for superhigh pressure, ultra high voltage, big electric current dry reactor winding is made the winding wire of multilayer transposition.
Background technology
At present, at national grid, in superhigh pressure and the extra-high voltage electric transmission and transformation engineering, the winding of various types of reactors and electrical equipment must tolerate high voltage and bigger electric current.Also to reduce the loss of electric energy simultaneously.
The dry reactor coil that uses in the electrical network, tradition is used all be the many wrapped round aluminum steels of sub-thread film and around.Because the coil diameter of dry reactor is very big, the number of turn is a lot, needs the length of lead to reach several kms.Like this multiple conducting wires and around coil in, the lead in the inboard and outside of each circle differs the width of two multiple conducting wires diameters on coil diameter.After the coiling multilayer, it is bigger that the length of every lead and resistance will differ.The leakage flux of generation in service like this will produce circulation " eddy current " in lead, cause bigger electric energy loss, and the reactor of general aluminum conductor coiling only is used for the electrical network less than 66KV, can not be used for superhigh pressure and ultra high voltage field.
The dry reactor coil that has adopts many round aluminium bare wires to be twisted into rectangle, and skin wraps up inner insulating layer, insulating barrier and composite membrane external insulation layer structure successively.The reactor of this lead coiling is only applicable to common high-voltage fence, and still can produce circulation in the lead that is in operation and cause eddy current loss.
Therefore, the winding wire that provides a kind of simple in structure, dependable performance, the wrapped round aluminum steel of film safe in utilization to do the multilayer transposition is one of these those skilled in the art problem that should address.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of superhigh pressure, ultra high voltage of being used for is provided, and simple in structure, the dependable performance of transformer and reactor, the wrapped round aluminum steel of film safe in utilization are made the winding wire of multilayer transposition.
The technical scheme that the utility model adopted is for achieving the above object: the wrapped round aluminum steel of a kind of film is made the winding wire of multilayer transposition, and it is characterized in that: this winding wire comprises the wrapped round aluminium multilayer transposition line of film, thin dielectric film and composite insulation layer; The wrapped round aluminium multilayer transposition line of described film is that the many zero defect sub-thread circle aluminum steels that have the insulation film lapping layer constitute the rectangle transposed conductor that multilayer is arranged; Described thin dielectric film is the insulation film lapping layer, and thin dielectric film is coated on the wrapped round aluminium transposition line of plural layers outside; Described composite insulation layer is the compound nonwoven cloth lapping layer that has insulation film, and composite insulation layer is coated on the thin dielectric film outside.

Operation principle of the present utility model and beneficial effect:
(1) owing to multilayer transposition aluminum conductor of the present utility model, is many and has the insulation film lapping layer, the rectangle transposed conductor that the multilayer that zero defect sub-thread circle aluminum steel is formed is arranged.The every round aluminum steel that constitutes transposed conductor all detects through nondestructive inspection, is high-quality sub-thread circle aluminum steel, the safety when having guaranteed to be used for superhigh pressure and extra-high voltage grid.
(2) in the utility model multilayer transposition aluminum conductor, the every wrapped round aluminum steel of film is in the pitch of regulation, according to the position of same angular transformation in transposed conductor, and the rectangle transposed conductor of formation multilayer arrangement. during with multilayer transposition aluminum conductor coiling reactor winding, the general employing stood around mode, therefore, in the reactor winding after the coiling, every wrapped round aluminum steel of film is constantly shifted one's position between the internal layer of transposed conductor and skin, remedied the wrapped round aluminum steel of each root film owing to be positioned at the formed length variation of diverse location of coil diameter, make that the every wrapped round aluminum steel of film length in coil is equal substantially, avoid and reduced since coil in the every different generation of conductor length eddy current loss. after tested, the resistance balance rate of the utility model multilayer transposition aluminum conductor is less than 1.2%, in the reactor operation test, compare the eddy current loss more than 70% that can reduce coil with the reactor of plain conductor coiling.
(3) the utility model multilayer transposition aluminum conductor is to adopt the many zero defect sub-thread circle aluminum steels that have the insulation film lapping layer, is combined into the multilayer transposed conductor through transposition, wherein every round aluminum steel mutually insulated.Coat thin dielectric film in the transposed conductor outside, composite insulation layer is coated on the thin dielectric film outside, has improved this product proof voltage grade.More than the average proof voltage 10000V of the utility model multilayer transposition aluminum conductor, more than the puncture voltage 26000V, be applicable to superhigh pressure and ultra high voltage field after tested.
(4) the utility model has been realized replacing copper material with aluminium, make superhigh pressure and the reactor in ultra high voltage field and the winding conducting wire of High-Voltage Electrical Appliances, saved China's copper resource very in short supply, and the price of aluminium only is 1/4 of a copper price, make rational use of resources, can reduce the construction cost of electrical network significantly.
In a word, the utility model is simple in structure, and is reasonable in design, safe in utilization, is widely used.
