Abstract
The invention relates to polyimide sintered film transposed conducting wires, in particular to a high-temperature resistant and corona resistant low-voltage coil winding wire for transformers, belonging to the technical field of coil winding wires. The invention is characterized in that the integrated film-transposed conducting wire is formed by adopting the following steps: winding the polyimide compound film around an oxygen-free copper flat-wire conductor to form single flat wires; arranging the single flat wires into two rows with the narrow edges contacting each other; adding intermediate sheathing paper between the two rows; forming whole-bunch wires via transposition; and winding the insulating layer of the aromatic polyamide paper for carrying out sintering to form integrated film transposed conducting wires. The invention has the advantages that the structure is compact and reasonable and the space occupied by the transformer is reduced; the insulation structure is stable, and has high heat resistance, radiation resistance and fire resistance; and the invention can improve the transformer resistance to short-circuit impact current, improve the running safety of the transformer and prolong the service life thereof.
Description
Technical field
The present invention relates to a kind of polyimides F-46 sintered film transposed conductor, specifically is the transformer reactance device low-voltage coil winding wire of a kind of high temperature resistant, high strength, anti-corona type, belongs to coil windings line technology field.
Background technology
Transformer, reactor are one of capital equipments of electric power system, play a part very importantly in electric power system, so accident and obstacle that they take place receive much attention.In recent years along with the progressively formation of China 500kV and above supergrid, the accident and the obstacle of 500kV and above transformer, reactor frequently take place, accident that coil took place and obstacle occupy the 1st, because of its coverage that causes wide, loss is serious, for this to 500kV and above transformer, reactor with the general requirement of winding wire is: insulation is stable, anti-short-circuit impact, mechanical structure intensity stabilization.Transposed conductor is as transformer, reactor low-voltage coil, and the lifting of its technical merit provides safeguard to the stable operation of electrical network.Traditional used insulating barrier of transposed conductor single line is the insulating varnish membrane structure, generally speaking, the tack performance of polyimides paint film is compared and is inferior to the acetal paint film, but the temperature resistant grade of acetal paint film has only the E level, must use the H level under some special operation conditions or the transposed conductor more than the H level improves its insulation level.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, the transposed conductor temperature resistant grade is brought up to the H level, improve the adhesive force between insulating barrier and the conductor, and can strengthen the polyimide sintered film transposed conductor of finished product overall mechanical strength thereby provide a kind of.
According to technical scheme provided by the invention, polyimide sintered film transposed conductor employing wrapped polyimide composite film layer outside oxygen-free copper lenticular wire conductor forms single lenticular wire, two row that single lenticular wire assortment becomes narrow limit to be in contact with one another, in the middle of two row in addition in the middle of lining paper, form whole bunch through transposition, outside whole bunch, twine aromatic polyamide paper insulation layer sintering and form the one film transposed conductor.
Compared with the prior art the utility model has the following advantages: the utility model compact conformation, reasonable, reduced the volume that takies transformer; Insulation system is stable, has very high heat resistant type, radiation resistance, and fire-retardant; Can improve transformer Short Circuit withstand impulse current ability, improve the safety in operation of transformer, and can increase the service life.
