Abstract
The utility model discloses a pressure-resisting power cable for an inverter, which comprises three alloy conductors with fan-shaped sections. A conductor shielding layer and an insulation layer are sequentially coated outside each alloy conductor. A Y-shaped pressure-resisting core which is extruded and molded by a thermoplastic elastomer material is provided. The three alloy conductors coated with the insulation layers are distributed outside the pressure-resisting core to together form a cable core. A wrapping layer, a shielding layer and a sheath layer are sequentially coated outside the cable core. The pressure-resisting power cable for an inverter is simple in structure; as the Y-shaped pressure-resisting core is arranged in the cable core, capacity of external extrusion resistance of the cable can be improved; and in addition, the cable has the advantages of resisting strong voltage surge, withstanding the frequency-converting pulse voltage, having strong capacity of effectively eliminating electromagnetic interference, reducing noise of the inverter motor and ensuring stability of the system.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of resistance to compression type frequency converter and uses power cable.
Background technology:
The insulating material that general frequency-changing cable adopts mainly is hard ethylene-propylene rubber and crosslinked polyethylene, and the electric property of the two is very superior, has equipment energy-conservation to pursue, and reduces equipment attrition, prolongs equipment life.The use of frequency conversion equipment is increasing to the demand of supporting with it private cable (calling frequency-changing cable in the following text), and specification requirement is also increasingly high.Because mostly the place mainly laid of frequency-changing cable be in the cabin, make frequency-changing cable to lay the space less, require the external diameter, weight, bending radius etc. of cable on the basis of guaranteed performance as far as possible little.
Original frequency-changing cable cable core often is squeezed, bending makes the cable core fracture, and electric power transfer is interrupted, and needs often to change.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of resistance to compression type frequency converter and uses power cable, under frequency-changing control system, makes service cable or major loop and connects usefulness, and anti-extraneous extrusion performance is superior, effectively protects cable core injury-free.
The technical scheme of the utility model is following:
Resistance to compression type frequency converter is used power cable; It is characterized in that: comprise that the cross section is three fan-shaped alloy conductors; Described three alloy conductors all are enclosed with conductor shield, insulating barrier outward successively; The resistance to compression core that the Y shape of thermoplastic elastic material extrusion moulding is arranged, the outside that three alloy conductors that are enclosed with insulating barrier are distributed in the resistance to compression core constitutes cable core jointly, and the cable core outside is enclosed with lapping layer, screen, restrictive coating successively.
Described resistance to compression type frequency converter is used power cable, it is characterized in that: it is crosslinked polyethylene that described insulating barrier adopts material.
The utility model has the advantages that:
The utility model is simple in structure; Between cable core, be provided with the resistance to compression core of Y shape; Improved the anti-extraneous extrusion capability of cable; This outer cable also has stronger proof voltage impact, the pulse voltage in the time of standing frequency conversion, and it is strong effectively to eliminate electromagnetic interference capability, reduces the advantage that the variable-frequency motor noise guarantees the stability of a system.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
Resistance to compression type frequency converter is used power cable; Comprise that the cross section is three fan-shaped alloy conductors 1; All be enclosed with conductor shield 2, insulating barrier 3 successively outside three alloy conductors 1, the resistance to compression core 4 of the Y shape of thermoplastic elastic material extrusion moulding is arranged, when receiving extraneous extruding; Can not wear and tear each other between the insulating barrier 3 of conductor and break; The phenomenon that disconnected core can not occur, the outside that three alloy conductors 1 that are enclosed with insulating barrier 4 are distributed in resistance to compression core 4 constitutes cable core jointly, and the cable core outside is enclosed with lapping layer 5, screen 6, restrictive coating 7 successively.
It is crosslinked polyethylene that insulating barrier 3 adopts material.
