Abstract
The utility model provides a frequency converter cable, which comprises a cable core. Flame retardant glass fiber filling ropes are filled in gaps of the cable. A copper wire braid layer, an inner protective layer and a shielding layer are sequentially arranged outside the cable, and an outer protective layer is located on the outmost side. The cable core is formed by twisting a plurality of wire cores. Each wire core comprises a middle conductor, a fireproof mica tape and an insulated layer, wherein the fireproof mica tape and the insulated layer are sequentially disposed outside the conductor. A flame retardant coating adhesive tape layer and a plastic wrap tape layer are wound on the outside of the insulated layer. A copper wire braid separated screen layer is arranged on the outer side of the plastic wrap tape layer. The frequency converter cable is capable of reducing occurrence rate of higher harmonics, electromagnetic radiation and interference sources, and meanwhile has the advantages of being fireproof, environment-friendly and the like.
Description
Technical field
The utility model relates to the electric wire field, specifically is a kind of converter cable.
Background technology
Frequency conversion provides a kind of outstanding supply power mode as the new development of power electronic technology to electric power environmental, but thing followed electromagnetic radiation has also increased obstacle for the application of frequency conversion.Modern " green " frequency converter has good inhibitory effect to high order harmonic component; Thereby the radiation of minimizing high order harmonic component; And the electric power that it is exported through cable has become interference source; Electric power system load and other electric equipments that closes on produced disturb, especially to anti-tampering high density instrument of having relatively high expectations, Harmonic Interference problems such as computer control system are particularly outstanding.As cable, though radiation is littler than frequency converter, in above-mentioned occasion; Cable Electromagnetic Radiation also becomes main radiation source, thereby the research frequency conversion is used power cable, the generation of minimizing high order harmonic component; Reduce electromagnetic radiation, improve the frequency conversion speed-adjusting system electromagnetic environment and should introduce attention, use power cable so design suitable frequency conversion; The radiation and the pollution of harmonic wave be could effectively reduce, the loss and the heating of motor reduced.
Summary of the invention
The utility model technical problem to be solved provides a kind of effective converter cable of electromagnetic radiation that suppresses.
A kind of converter cable, it comprises cable core, in the slit of cable core, fills flame-proof glass fibre dimension gasket for packing, outside cable, sets gradually copper wire braid, sheath, screen, outermost is an oversheath.
Said cable core forms by some cores are stranded; Core comprises middle conductor and is successively set on conductor outer fire-resistant isinglass belt, insulating barrier; At insulating barrier wrapped fire-retardant gummed cloth belt in outside and plastic packets belt, be provided with copper wire braiding sub-shield in the plastic packets belt outside.
Screen is preferably by copper wire and reverse wrapped the dredging around screen of tightening of copper strips.
The utility model can reduce the generation of high order harmonic component, reduces electromagnetic radiation, reduces interference source.Dredging around screen is that copper wire+copper strips is wrapped, when taking place to puncture, plays drainage, is unlikely to life-threatening safety, can also avoid electric charge accumulation causing electric field to concentrate in time with the electric charge carrying-off, also serves as screen and uses.Sheath is the low smoke and zero halogen material, and is nonflammable when breaking out of fire, do not produce harmful substance, guarantees safety, and the assurance electric power system is supplied power normally.Skin is a silicone rubber jacket.Silicone rubber jacket has waterproof, anti-salt fog, and characteristics such as anticorrosion oil resistant are exactly breaking out of fire, and cable can not produce a large amount of dense smoke yet.In cable, add fire-resistant mica layer, made cable possess fire-resistant function, improved the security of operation of cable and various device.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
With reference to Fig. 1; The utility model control cable comprises cable core; Cable core forms by some cores are stranded; Said core comprises middle conductor 1 and is successively set on conductor outer fire-resistant isinglass belt 2, insulating barrier 3 that the wrapped second fire-retardant gummed cloth belt 4 and plastic packets belt 5 in insulating barrier 3 outsides is provided with copper wire braiding sub-shield 6 in plastic packets belt 5 outsides.In the slit of cable core, fill flame-proof glass fibre dimension gasket for packing 7, outside cable, set gradually copper wire braid 7, sheath 8, screen, this screen is that outermost is an oversheath 11 by copper wire 10 and copper strips 9 reverse wrapped dredging around screen of tightening.
The preparation technology of the utility model is: core is a wrapped fire-resistant isinglass belt 2 on conductor 1, and conductor adopts the 5th type of annealed copper wire or tin annealed copper wire.The fire-resistant isinglass belt 2 outer one deck XLPE insulating barriers 3 that extrude, fire-retardant gummed cloth belt 4 of the outer wrapped one deck of insulated wire cores and plastic packets belt 5, the outside is woven into copper wire braiding sub-shield 6 with copper wire again.Then by some core strandings; Fill and use flame-proof glass fibre dimension gasket for packing 7, the outside weaves one deck copper wire braid 7 again and does the turnkey layer, extrudes sheath then; Sheath is outward that outermost is an oversheath 11 by copper wire 10 and copper strips 9 reverse wrapped dredging around screen of tightening.
The utility model provides a kind of thinking and implementation method of converter cable; Concrete application approach is a lot; For those skilled in the art; Under the principle that does not break away from the utility model, can also make some improvement, these improve the protection range that also should be regarded as the utility model.
