CN205318886U - Magnetic suspension three -core flat cable - Google Patents

Abstract

The utility model discloses a magnetic suspension three -core flat cable, this cable are the flat structure, and the cable center is equipped with two looks sinle silks that tie for, and a plurality of ground wire core conductor of parallel configuration round outside the looks sinle silk, ground wire core conductor wind the band around the package outward, crowd the package sheath outward around the band. The utility model discloses the utensil makes the cable suspension through the electro -magnet, does not contact with the external world to play the effect of shock insulation, protection of cables meets an urgent need when the earthquake.

Description

A kind of magnetic levitation three core flat cable

Technical field

The utility model relates to electric wire field, especially a kind of magnetic levitation three core flat cable.

Background technology

For earthquake prone areas, the cable being embedded in underground is given a shock for a long time, it is easy to fault occurs.

Triple core cable in prior art, usual structure is all that be extruded with the circular core of insulation by three stranded, or three fan-shaped cores are stranded. Triple core cable core comprises the identical third-class core in three conductor cross sections or two 2+1 cores that conductor cross section is big, a conductor cross section is little, lacks corresponding isolation measure.

Practical novel content

The utility model is overcome the shortcoming that prior art exists, it provides a kind of safe and reliable, isolating affection is good, it may also be useful to life-span length magnetic levitation three core flat cable.

For solving above technical problem, a kind of magnetic levitation three core flat cable described in the utility model, this cable is flat shape structure, cable center is provided with two phase cores arranged side by side, outside phase core, some wire core conductors are enclosed in arrangement one side by side, the outer wrapped twining package tape of wire core conductor, extrudes sheath, is intervally distributed with some electro-magnet in sheath outside twining package tape.

Described phase core is by phase conductor and wrapped forms at the outer twining package tape of phase conductor.

Described phase conductor is stranded and become by some monofilament.

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.

The useful effect of the utility model is: by electro-magnet, cable is suspended, and not with extraneous contact, thus plays the effect every shake, the emergency protection cable when earthquake.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further elaborated:

As shown in Figure 1, a kind of magnetic levitation three core flat cable described in the utility model, this cable is flat shape structure, cable center is provided with two phase cores 1 arranged side by side, at an outer arrangement side by side circle some wire core conductors 4 of phase core 1, the outer wrapped twining package tape 3 of wire core conductor, extrudes sheath, is intervally distributed with some electro-magnet 5 in sheath outside twining package tape. Described phase core is by phase conductor 2 and wrapped forms at the outer twining package tape 3 of phase conductor 2; Described phase conductor 2 is stranded and become by some monofilament 6; 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.

Being embedded with the magnetic pole contrary with electro-magnet magnetic in cable around cable, during earthquake, electro-magnet is energized, and makes cable produce to suspend, and avoids and extraneous physical contact, thus greatly slow down and shake the damage to cable.

Above-mentioned is only preferred implementation of the present utility model; it is noted that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also making some improvement and adjustment, these improve and adjustment also should be considered as protection domain of the present utility model.
