Abstract
The invention discloses a three-core insulating sheath metal shielding power cable. The three-core insulating sheath metal shielding power cable comprises power cable cores, monitoring cable cores, a metal shielding layer and a polytetrafluoroethylene outer sheath layer, wherein each power cable core is formed by extruding a flame-retardant silicon rubber insulating layer on an aluminum alloy stranded conductor; each monitoring cable core is formed by extruding a flame-retardant silicon rubber insulating layer on four copper core stranded conductors; a connecting plane is processed on each power cable core; three power cable cores are connected with a hollow triangular fiber core; three monitoring cable cores are arranged at intervals on the outer sides of the three power cable cores, and are coated into cable cores through the metal shielding layer; intervals in the cable cores are filled with a ceramic powder filler; the polytetrafluoroethylene outer sheath layer is formed outside the cable cores. The three-core insulating sheath metal shielding power cable is simple in structural design, has stable performance, and can meet the performance requirements of a flame-retardant cable under a high-temperature-resistant condition. Moreover, the cable is soft and is easy to pave, the weight requirement on the cable is low, relative movement among the cables is not produced, and a signal monitoring function is realized.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of three core insulation sheath metallic shielded power cables.
Background technology
Development along with frequency drive technology processed, requirement to frequency variable ratio drive system is more and more higher, especially to adopting the modern converter technique of IGBT semiconductor of quick switching, although pulse frequency is high or more they generate an electromagnetic field to surrounding environment only in millisecond the break time.For keeping the normal work of frequency converter not to be subject to electromagnetic interference, therefore connect cable between frequency converter and three phase alternating current motor and will there is interference free performance, lower effective capacitance and lower transfer impedance, also needing has good electromagnetic compatibility, the characteristic of resistance to sparking energy and high temperature flame-proof, and require lighter to the weight of cable, between cable core, do not produce relative shift, there is the function of signal monitoring.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of three core insulation sheath metallic shielded power cables.
The solution of the present invention is as follows: a kind of three core insulation sheath metallic shielded power cables, comprise power core, monitoring core, metal screen layer and polytetrafluoroethylene external sheath layer, described power core is to be extruded on aluminium alloy stranded conductor and to be formed by flame-proof silicon rubber insulating barrier; Described monitoring core is by flame-proof silicon rubber insulating barrier, to extrude four copper core stranded conductors to form; Described power core is processed with connection plane, and three power cores are connected with hollow triangle fibre core; Three monitoring cores are arranged on interval outside three power cores, by metal screen layer, are coated as cable core; Ceramic powder filled thing is filled up at interval in described cable core; Described cable core is outside equipped with polytetrafluoroethylene external sheath layer.
Described metal screen layer adopts proof copper-wire braided and copper strips is wrapped combines.
Beneficial effect of the present invention: structural design of the present invention is simple, stable performance, can meet under high temperature resistant condition and the performance requirement of flame retardant cable, and cable softness is easy to lay, electromagnetic compatibility, resistance to sparking can be good, and the weight ratio of cable is lighter, between cable core, do not produce relative shift, there is good signal monitoring function.

Wherein: 1, power core; 2, aluminium alloy stranded conductor; 3, flame-proof silicon rubber insulating barrier; 4, ceramic powder filled thing; 5, monitoring core; 6, metal screen layer; 7, polytetrafluoroethylene external sheath layer; 8, fibre core; 9, copper core stranded conductor.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of three core insulation sheath metallic shielded power cables, comprise power core 1, monitoring core 5, metal screen layer 6 and polytetrafluoroethylene external sheath layer 7, described power core 1 is to be extruded on aluminium alloy stranded conductor 2 and to be formed by flame-proof silicon rubber insulating barrier 3; Described monitoring core 5 is by flame-proof silicon rubber insulating barrier 3, to extrude four copper core stranded conductors 9 to form; Described power core is processed with connection plane, and three power cores 1 are connected with hollow triangle fibre core 8, and fibre core adopts hollow triangle structure, guaranteed the steadiness connecting, prevented from being shifted in moving process, and boring structure, structure is light, and whole cable diameter is reduced; Three monitoring cores 5 are arranged on three power cores, 1 interval, outside, by metal screen layer 6, are coated as cable core; Ceramic powder filled thing 4 is filled up at interval in described cable core, fire-retardant, high temperature resistant; Described cable core is outside equipped with polytetrafluoroethylene external sheath layer 7.
Described metal screen layer 6 adopts proof copper-wire braideds and copper strips is wrapped combines.
The conductor of power core 1 forms by aluminium alloy conductor is stranded, easily lay, insulating barrier all adopts flame-proof silicon rubber material, silastic material heat resisting temperature is high, there is flame-retarding characteristic, and the pliability that improved cable, and there is flame-retarding characteristic, metal screen layer 6 can effectively suppress the electromagnetic interference on inside and outside boundary, in addition the structural behaviour of the symmetrical core band shielding of 3+3 is best, adopt symmetrical shielded type cable also can reduce the electromagnetic radiation of drive system, and reduce the shaft current of motor and the bearing wear causing thus.Polytetrafluoroethylene external sheath layer 7, plays a protective role to cable, heat insulation, oxygen barrier effect; And monitoring core 5 is of value to the performance of tracking and testing cable, practical and convenient.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
