Abstract
The invention provides a large-capacity breakdown-type cable, which comprises a phase core and a neutral core, wherein each phase core is twisted together to form a cable core; a grounding layer is wrapped outside the neutral core of the cable; the cable core is separated from the neutral core which is provided with the grounding layer; and through the technical scheme, the current carrying capacity of each cable core can be greatly improved, and the transmission capacity and the power supply quality of the cable can be improved.
Description
Technical field
The present invention relates to a kind of cable, especially a kind of large-capacity breakdown-type cable.
Background technology
At present, at the structure of taking Fig. 1, Fig. 2 usually of laying of big volume transport cable more than the 1KV.Big volume transport cable is as shown in Figure 1 concentrated laying structure, though cable core is concentrated, lays conveniently, and each core radiating condition is relatively poor, and current-carrying capacity of cable is lower; Big volume transport cable laying structure arranged side by side as shown in Figure 2, each core radiating condition of cable is better, but core lays comparatively trouble, and because the core symmetry is relatively poor, the ampacity imbalance that can cause each phase line, the effective transmittability and the power supply quality of reduction cable.
Summary of the invention
The present invention is for solving in the prior art, big volume transport cable laying structure radiating effect is poor, current-carrying capacity of cable is low, perhaps because core symmetry difference causes technical problems such as each phase line current-carrying imbalance, a kind of large-capacity breakdown-type cable simple and reasonable for structure is provided, the ampacity of each core of cable be can improve greatly, cable transmission ability and power supply quality promoted.
The present invention is for achieving the above object, and the technical scheme that is adopted provides a kind of large-capacity breakdown-type cable, comprises phase core, neutral core; Described each phase core twists together the formation cable core; Described neutral core is wrapped with ground plane; Described cable core splits mutually with the neutral core that is enclosed with ground plane.
Further, the described ground plane that is wrapped in outside the neutral core is a linear structure, and the ground plane of described linear structure is wrapped in outside the neutral core.
Further, described each phase core is outside equipped with sheath, is outside equipped with sheath at the ground plane that wraps up neutral core.
Further, described sheath is a tooth-shape structure.
Further, be provided with fixture outside the described cable core.
Further, described cable core fixture is a woven wire.
The present invention compared with prior art, its effect is actively and significantly.Twist together the formation cable core by each phase core, guaranteed the equilibrium of each phase line ampacity of cable cable; The neutral core of cable is split with cable core, improved the ampacity of phase core and neutral core greatly; Ground plane is wrapped in outside the neutral core, has played excellent shielding effect; Each phase core and neutral core all are provided with the profile of tooth protective sleeve outward, have increased the area of dissipation of cable, have improved the transmittability of cable.
Description of drawings
Fig. 1 is the concentrated laying structure schematic diagram of the big volume transport cable of prior art;
Fig. 2 is the laying structure schematic diagram arranged side by side of the big volume transport cable of prior art;
Fig. 3 is the structural representation of large-capacity breakdown-type cable of the present invention.
Embodiment
The present invention is described further below in conjunction with accompanying drawing.
The concentrated laying structure of big volume transport cable as shown in Figure 1, this structure comprise phase core 1, neutral core 2, ground connection core 3 and cable protective sleeve 4; Because each phase core 1 of cable, neutral core 2 and ground connection core 3 all twist together, so the cable radiating effect is poor, ampacity is low.
Big volume transport cable as shown in Figure 2 lay mechanism side by side, this structure is laid phase core 1, neutral core 2 and ground connection core 3 side by side; Though the cable radiating effect is better than structure shown in Figure 1 like this, core lays trouble, and because each phase core symmetry is relatively poor, can cause the unbalanced of isopen ampacity not, reduces the cable transmission ability.
Be illustrated in figure 3 as the structural representation of large-capacity breakdown-type cable of the present invention.In the technical program, each phase core 1 is twisted together the formation cable core; Neutral core 2 is split with cable core; Neutral core 2 is wrapped with ground plane 6; Ground plane 6 can be copper wire, and is wrapped in neutral core 2 outsides; Each the phase core 1 and neutral core 2 outsides all are provided with sheath 5, and sheath 5 is a tooth-shape structure; The cable core that phase core 1 is twisted into is outside equipped with fixture 7, and fixture 7 can be woven wire, by the effect of fixedly tightening up of fixture 7, tightens up each phase core 1 of cable fixing.
Each phase core 1 twists together, and has guaranteed the equilibrium of each phase line ampacity of cable; With splitting of neutral core 2 and cable core, can improve the ampacity of phase core 1 and neutral core 2 greatly; The ground plane 6 of neutral core 2 outer wrapping has also played excellent shielding effect; The profile of tooth sheath 5 that each phase core 1 and neutral core 2 are outer has increased the area of dissipation of cable, has improved the transmittability of cable.
