Abstract
The invention discloses an intermediate-frequency low-consumption balance rubber sleeve cable for ships, which comprises a cable core in the middle of the cable. A filler is disposed in a gap in the cable core, an inner protective layer is arranged outside the cable core, a tinned copper wire braided shielding layer is braided outside the inner protective layer, and an outer protective layer is arranged outside the tinned copper wire braided shielding layer in an extruding mode. The cable core is formed by stranding a plurality of wire cores, and each wire core is formed by a middle conductor and an insulated layer wrapped on the outer surface of the conductor in an extruding mode. The intermediate-frequency low-consumption balance rubber sleeve cable for ships adopts tinned copper wire braiding and is capable of reducing effect of outside equipment and an electric field on the cable. Deviation between phases of the cable is small so that balance of each phase is guaranteed, Kelvin effect and proximity effect of the cable caused by imbalance are reduced, and meanwhile, the problem that pressure drop is large caused by resistance and reactance between cable cores is relieved.
Description
Technical field
The present invention relates to a kind of power cable, specifically is that being electrically connected of a kind of naval vessel intermediate frequency electric equipment and intermediate frequency power supply used cable.
Background technology
It is on the naval vessel, to provide power supply used a kind of cable as the intermediate frequency electric device that the naval vessel uses immediate frequency cable, and existing naval vessel cable is power frequency 50Hz, and conductor is common zinc-plated five types of conductors, and insulating material is common ethylene propylene diene rubber.The structure of the general immediate frequency cable that uses is extruded insulation and a lapped insulation shielding composition core on the single copper conductor on the naval vessel, and filler is set outside cable core then, and wrapped again formation lapping layer weaves the copper wire braid at last and extrudes oversheath.
Problem and shortcoming that prior art exists:
1) the intermediate frequency plant capacity is big, moment starting current big, existing naval vessel cable is a low-frequency cable, little with power under the situation of cross section, ampacity is less, may cause intermediate frequency equipment to be difficult to start, even can cause device damage.
2) conductor is common five types of conductors; The conductor twisting pitch is bigger, and the conductor resistance deviation is bigger between the every phase of multicore cable, and transmission current is unstable; The resistance between the core and the instability of impedance can cause the obvious of skin and proximity effect comparison that become between every phase, can cause the pressure drop of cable excessive.
3) common insulating material does not belong to low medium ethylene propylene diene rubber, can cause because the higher use that influences cable of dielectric loss of insulating material.
4) the increasing employing intermediate frequency of war products equipment, the existing immediate frequency cable that uses all is imported product, is unfavorable for national defense safety and national security from particularity, the confidentiality angle of naval's equipment.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of naval vessel that can better satisfy actual needs with intermediate frequency low consumption balance Plastic-sheathed Cable.
A kind of naval vessel of the present invention is with intermediate frequency low consumption balance Plastic-sheathed Cable; Comprise the cable core that cable is middle, the slit between cable core is provided with filler, and sheath is set outside cable core; Outside sheath, weave the tinned copper wire woven shield, outside the tinned copper wire woven shield, extrude outer jacket.
Said cable core has that the several wire core is stranded to form, and core then is made up of the conductor of centre and the insulating barrier that is extruded in the conductor outer surface.
The invention solves the excessive and every phase conductor resistance of numerical value such as pressure drop, electric capacity, inductance of existing shipboard cable and the problem of the disequilibrium between the insulation resistance; The braiding of employing tinned copper wire; Count >=80% can reduce the influence that external equipment and electric field cause cable.Deviation is less between the every phase of cable, has guaranteed the balance of every phase, has reduced cable because imbalance causes skin effect and proximity effect, simultaneously, can reduce because the excessive problem of pressure drop that resistance and reactance cause between the core.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1,
Fig. 2 is the structural representation of the embodiment of the invention 2.
Embodiment
As depicted in figs. 1 and 2; A kind of naval vessel of the present invention comprises the cable core that cable is middle with intermediate frequency low consumption balance Plastic-sheathed Cable, and said cable core is by three (Fig. 1) or four stranded forming of (Fig. 2) core; Core is then by the conductor 1 of centre and be extruded in the slit that the insulating barrier 2 of conductor 1 outer surface forms between cable core and be provided with filler 3; Sheath 4 is set outside cable core, and braiding tinned copper wire woven shield 5 extrudes outer jacket 6 outside tinned copper wire woven shield 5 outside sheath 4.
Characteristics of the present invention:
1, conductor adopts tinned conductor, monofilament deviation to guarantee at ± 0.001mm layer-stranding when stranded; Every layer of pitch multiple proportions is controlled in 12; Guarantee stranded compactness, the conductor distortion is little, simultaneously; Guarantee that every monofilament or synnema strand can not have welding or joint, guarantee every phase conductor resistance deviation≤1%.
2, the EPDM electro-insulating rubber material of dielectric loss≤0.02, insulation resistance>=5000 M Ω/km is adopted in insulation of the present invention, guarantees every phase insulation resistance deviation≤1%.
3, the three-layer co-extruded moisture balance extruder of insulating exruded employing import is extruded, and guarantees insulating exruded tight type, does not have steam to get into conductor, guarantees insulation eccentricity degree≤10%.
4, during stranding, the pitch multiple proportions is controlled in 10 times, guarantees the stranded tight non-loosening of core, guarantees between every phase balance each other.
5, adopt the tinned copper wire braiding behind the stranding, count >=80% can reduce the influence that external equipment and electric field cause cable.
6, above control mode can guarantee that deviation is less between every phase; Guaranteed the balance of every phase; Reduced cable because imbalance causes skin effect and proximity effect, simultaneously, can reduce since between the core because the excessive problem of pressure drop that resistance and reactance cause.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
