Abstract
The utility model relates to a film sintering transposition wire which is applicable to the film sintering transposition wires of stator winding wires used for traction electric machines of high-speed railways. The inner layer is formed by dividing the odd number of film sintering copper flat wires into two lines and weaving, and is externally wrapped by at least three layers of NOMEX aramid fiber insulation paper. The utility model has the advantages that: the film sintering transposition wire has high insulation strength and high-temperature resistance, coils are free of maintenance for life, and the film sintering transposition wire is a novel energy-saving environmentally-friendly winding wire, and has very strong practicality and very high popularization and application values.
Description
Technical field
The utility model relates to a kind of film sintered transposed conductor that is applicable to the high-speed railway traction electric machine with the stator winding line.
Background technology
The high-speed railway traction electric machine with the stator winding line because the running up of train, its winding conducting wire should have good temperature resistance energy, the high requirement of dielectric strength, but what its insulating material of present lead had can not satisfy above-mentioned requirements, the cost that has environmental-protecting performance too high, that have is not all right, and range of application all is subjected to certain limitation.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of film sintered transposed conductor, and this transposed conductor can satisfy the high-speed railway traction electric machine and use with the stator winding line.
The technical solution of the utility model is: internal layer of the present utility model is that the film sintered copper strap wire of odd number root is worked out in two separate ranks, at least three layers of NOMEX aramid fiber of internal layer outsourcing insulating paper.
Described film sintered copper strap wire is the polyimides F46 laminated film of half-stack package one deck 0.13mm～0.15mm on the bare copper flat wire.
The thickness of described polyimides F46 laminated film is 0.038mm.
The utility model has the advantages that: the utlity model has the advantage of dielectric strength height, high temperature resistant, coil maintenance-free, is a kind of novel energy-saving environment-friendly type winding wire, has very strong practicality and very high application value.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that bare copper flat wire, 2 is that polyimides F46 film, 3 is NOMEX aramid fiber insulating paper among the figure.
Embodiment
Internal layer of the present utility model is that the film sintered copper strap wire of odd number root is worked out in two separate ranks, at least three layers of NOMEX aramid fiber of internal layer outsourcing insulating paper 3.
Described film sintered copper strap wire is the polyimides F46 laminated film 2 of half-stack package one deck 0.13mm～0.15mm on the bare copper flat wire 1.
Through overtesting, the thickness of polyimides F46 laminated film 2 of the present utility model is preferably 0.038mm.
The polyimides F46 laminated film 2 of the utility model 50% stacked package one deck 0.038mm on the bare copper flat wire of producing with extrusion molding 1 is through 400 ℃ of left and right sides high frequency sintering, take-up after the water cooling.Again the film sintered copper strap wire of odd number root is replaced in two separate ranks, the NOMEX aramid fiber insulating paper 3 of outsourcing more than three layers, concrete insulation thickness is decided according to actual conditions.
