Description
Technical field
The utility model relates to a kind of crossover sub of cable link, particularly relates to a kind of crossover sub for being connected between the linear induction motor armature winding on the magnetic-levitation train and the power cable.
Background technology
Linear electric motors are a kind of New-type electric machines, are applied in recent years replacing on the magnetic-levitation train traditional electric rotating machine as power source.Because linear electric motors length is longer, and the electric motor primary winding need be installed on the magnetic-levitation train, therefore need limit motor weight, the wire rod of armature winding changed to aluminium by traditional copper material, can alleviate like this 2/3rds winding weight, and can reduce cost.But, because the linear electric motors power cable is copper material, and armature winding is aluminium, thereby when motor was installed, copper material and aluminium directly were welded to connect, and caused joint to have the defectives such as heatproof is low, intensity difference, heating is serious under large current conditions, postwelding splice insulation wrapping is of low quality, and, copper aluminium welding technique is loaded down with trivial details, and is not easy to operate, and welding quality is very unstable.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of copper material and aluminium can avoided directly to weld, and easy and simple to handle, the crossover sub of the linear electric motors cable link that strength of joint is high, heatproof is high, switching performance is reliable and stable.
For solving the problems of the technologies described above, the utility model adopts a kind of like this crossover sub of linear electric motors cable link, be used for being connected between linear electric motor primary winding and the power cable, this crossover sub comprises the aluminium jointing of being made by aluminium and the copper material jointing of being made by copper material, the upper end of described aluminium jointing is used for connecting the lead-out wire of linear electric motor primary winding, and the shape of this aluminium jointing upper end and the shape of described linear electric motor primary winding leading-out wire are suitable; The lower end of described copper material jointing is used for connecting power cable, and the shape of this copper material jointing lower end and the shape of described power cable are suitable; The copper-aluminium transition section that the lower end of described aluminium jointing forms by explosive welding (EW) is fixedly connected with the upper end of described copper material jointing and is integral.
As a kind of preferred implementation of the present utility model, the cross sectional shape of the top and bottom of described aluminium jointing is rectangle, and the area of section of lower end is greater than the area of section of upper end; The cross sectional shape of the upper end of described copper material jointing is rectangle, and being shaped as of the lower end of copper material jointing has the cylindrical of endoporus; The cross sectional shape of described copper-aluminium transition section is rectangle, and the area of section of this copper-aluminium transition section equates with the top surface area of described copper material jointing upper end and the base area of described aluminium jointing lower end.
After adopting said structure, because the aluminium jointing of crossover sub links to each other with the aluminium lead-out wire of linear electric motor primary winding, the copper material jointing of crossover sub links to each other with the copper material power cable, therefore, in the linear electric motors installation process, only carry out welding or crimping between aluminium-aluminium, the copper-copper, avoided the direct welding between the copper and aluminium in the prior art, thereby greatly improved the quality of connection between power cable and the armature winding, guarantee stability and the reliability of large electric current lower contact, greatly reduced conductor joint heating seriously and the possibility of weld cracking.In addition, when mounted, the conductor wire core of power cable can be concentrated in the endoporus that inserts copper material jointing lower end, thereby avoided the loose drawback with puncturing insulation of core, simplify the insulating wrapping of joint weld, guarantee the insulation quality of joint.
