Description
Technical field
The utility model relates to cable, particularly relates in one and presses intelligent frequency-conversion cable.
Background technology
At present, along with the development of electric power, electronic technology and computer technology, medium voltage converter cable is used more and more in machine-building, metallurgy, mine, railway, industry etc., simultaneously along with frequency conversion equipment is constantly to high-tech, high-performance future development, the function of its complexity is to the higher requirement of matching used cable proposition with it.Traditional frequency-changing cable outside three insulated wire cores and three zero line cores, sets gradually lapping layer, metal screen layer and outer jacket form; form the structure (i.e. 3+3 structure) that three large cores add the symmetrical stranding of three little cores; pulse voltage when making cable can stand highly frequent frequency conversion, plays a good protection to frequency conversion.But traditional 3+3 complex structure, the outside diameter of cable is large, the especially medium voltage converter cable of 3kv-35kv.In addition, according to the 3+3 construction of cable, must on 1+6 cabler stranding, and heavy in section medium voltage converter cable 1+6 equipment can not meet the demands, and becomes production. art more complicated.
In addition, some cable enterprises add light inlet pricker unit and come monitoring and measuring information and feedback information better in frequency-changing cable, as Chinese patent " frequency-changing cable " (publication number: CN202549451U, publication date is on November 21st, 2012) in disclose a kind of optical fiber composite waterproof frequency-changing cable adding warning, temperature survey and frequency feedback and signal transfer functions, which employs 3+3 mechanism, at the outer wrapped metal screen layer of core and armour.For midium voltage cable, because pulse voltage during frequency conversion is high, simple copper strips repeats wrappedly to play protective effect completely to frequency converter, and adopts the structure of 3+3, then comparatively large, the production technology more complicated of its molding cable external diameter.
Utility model content
For solving above-mentioned the problems of the prior art, the utility model provides and a kind ofly can meet the pulse high-voltage shielding frequency converter under high voltages, in time frequency, signal can be transmitted and feedback in time again, and external diameter is less, the simple middle pressure intelligent frequency-conversion cable of structure.
The technical solution adopted in the utility model is for pressing intelligent frequency-conversion cable in open one: comprise cable core, be coated on the protective layer of described cable core periphery, be filled in the filler between described cable core and described protective layer, wherein, described cable core forms by three core unit are stranded, it is by separator that each described core unit comprises, metal screen layer, insulation screen, insulating barrier and conductor shield are formed from being in turn coated on conductor wire core outside to inside, described metal screen layer is wound around by copper wire and copper strips and is formed, described protective layer is coated with wrapped belt from inside to outside successively, armour, restrictive coating, described armour adds copper strips winding by copper wire and forms, the center position of described cable core is provided with fiber unit.
Further, described conductor shield employing can not exfoliated semiconductive material.
Further, described insulating barrier adopts cross-linking polyethylene materials.
Further, described insulation screen adopts peelable or can not exfoliated semiconductive material.
Further, described separator adopts polythene material.
Further, described filler adopts flame-retardant polypropelene material.
Further, described restrictive coating adopts halogen-free anti-flaming polyolefin material.
By above-mentioned technical scheme, the beneficial effects of the utility model are:
1. by the outer wrapped metal screen layer of conductor wire core and at the outer wrapped armour of cable core, middle pressure intelligent frequency-conversion cable of the present utility model can meet the pulse high-voltage under high pressure shielding frequency converter;
2. arrange fiber unit by the center position at cable core, frequency, signal can transmit and feedback by middle pressure intelligent frequency-conversion cable of the present utility model in time in time;
3. the external diameter of middle pressure intelligent frequency-conversion cable of the present utility model relatively will little and structure simple, thus will be widely used in machine-building, mine, metallurgy industry.

Conductor wire core 1; Conductor shield 2; Insulating barrier 3; Insulation screen 4; Metal screen layer 5; Separator 6; Filler 7; Wrapped belt 8; Armour 9; Restrictive coating 10; Fiber unit 11.
Embodiment
By reference to the accompanying drawings and embodiment will further illustrate the technical solution of the utility model.
As shown in Figure 1, middle pressure intelligent frequency-conversion cable of the present utility model comprises cable core, be coated on the protective layer of described cable core periphery, be filled in filler 7 between described cable core and described protective layer, wherein, described cable core forms by three core unit are stranded, each described core unit is made up of from being in turn coated on outside to inside on conductor wire core 1 separator 6, metal screen layer 5, insulation screen 4, insulating barrier 3 and conductor shield 2, and described metal screen layer 5 is wound around by copper wire and copper strips and is formed; Described protective layer is coated with wrapped belt 8, armour 9, restrictive coating 10 from inside to outside successively, and described armour 9 adds copper strips winding by copper wire and forms.
Preferably, described conductor shield 2 employing can not exfoliated semiconductive material.
Preferably, described insulating barrier 3 adopts cross-linking polyethylene materials.
Preferably, described insulation screen 4 adopts peelable or can not exfoliated semiconductive material.
Preferably, described separator 6 adopts polythene material.
Preferably, described filler 7 adopts flame-retardant polypropelene material.
Preferably, described restrictive coating 10 adopts halogen-free anti-flaming polyolefin material.
Based on said structure; by being wound around copper wire and copper strips outward at core and the metal screen layer proof voltage impact formed is strong; the impulse electric field produced when can shield height frequency conversion under high voltage completely effectively; play a protective role to frequency converter, more traditional 3+3 structure external diameter will reduce more than 10% simultaneously.The separator extruded outside metal screen layer is used for metal screen layer isolation and protection.In addition, by being wound around one deck armour (screen) at formed body external application copper wire and copper strips, magnetic field is shielded, thus reduce the harmful effect in magnetic field.The fiber unit being arranged on cable core center additionally provide various state is monitored, frequency feedback, temperature survey, Signal transmissions and warning etc. function.Thus, by above-mentioned described technical scheme, the structure of frequency-changing cable of the present utility model is comparatively simple.
