Abstract
The invention discloses a magnetic levitation type three-core flat cable. The cable is of a flat structure. Two phase wire cores in parallel are arranged in the center of the cable. A circle of multiple ground wire core conductors are arranged in parallel outside the phase wire cores. The ground wire core conductors are wrapped with a warping tape. A sheath is extruded outside the warping tape. According to the magnetic levitation type three-core flat cable, the cable is levitated through an electromagnet and is not in contact with the outside, so that a seismic insulation effect is achieved and the cable is protected in emergency during earthquake.
Description
Technical field
The present invention relates to electric wire field, especially a kind of magnetic suspension three core flat cable.
Background technology
For earthquake prone areas, the cable being embedded in underground is given a shock for a long time, easily breaks down.
Three-core cable in prior art, usual structure is all that three to be extruded with the circular core of insulation stranded, or three segment conductor-cores are stranded.Three-core cable core comprises the identical third-class core of three cross-sectional area of conductor or two 2+1 cores that cross-sectional area of conductor is large, a cross-sectional area of conductor is little, lacks corresponding isolation measure.
Summary of the invention
The present invention overcomes the shortcoming that prior art exists, and provide a kind of safe and reliable, isolating affection is good, long service life magnetic suspension three core flat cable.
For solving above technical problem, a kind of magnetic suspension three core flat cable of the present invention, this cable is squashed structure, cable center is provided with two phase cores arranged side by side, some wire core conductors are enclosed at the outer laid out in parallel one of phase core, the outer wrapped twining package tape of wire core conductor, extrudes sheath outside twining package tape, is intervally distributed with some electromagnet in sheath.
Described phase core is by phase conductor and wrappedly form at the outer twining package tape of phase conductor.
Described phase conductor forms by some monofilament are stranded.
The described equidistant gap arrangement of wire core conductor or be covered with at phase core peripheral, its diameter is identical with the filament diameter of formation phase conductor.
Described wire core conductor is solid naked round conductor or the filled circles conductor for extruding insulation.
Beneficial effect of the present invention is: by electromagnet, cable is suspended, and not with extraneous contact, thus plays the effect of shock insulation, the emergency protection cable when earthquake.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, a kind of magnetic suspension three core flat cable of the present invention, this cable is squashed structure, cable center is provided with two phase cores 1 arranged side by side, some wire core conductors 4 are enclosed at the outer laid out in parallel one of phase core 1, the outer wrapped twining package tape 3 of wire core conductor, extrudes sheath outside twining package tape, is intervally distributed with some electromagnet 5 in sheath.Described phase core is by phase conductor 2 and wrappedly form at the outer twining package tape 3 of phase conductor 2; Described phase conductor 2 forms by some monofilament 6 are stranded; The described equidistant gap arrangement of wire core conductor 4 or be covered with at phase core peripheral, its diameter is identical with monofilament 6 diameter of formation phase conductor; Described wire core conductor 4 is solid naked round conductor or the filled circles conductor for extruding insulation.
Be embedded with the magnetic pole contrary with electromagnet magnetic in cable around cable, during earthquake, electromagnet is energized, and cable is produced and suspends, avoid and extraneous physical contact, thus greatly slow down the damage of vibrations to cable.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improve and adjustment also should be considered as protection scope of the present invention.
