Principle of the present invention:
(1) temperature rise determines safe current capacity
Electrician's rule speech: the transmission current that (25 ℃) are no more than maximum safety temperature at certain environment temperature is called ampacity, has another name called " safe current ".But the safe current capacity of all size cable depends on the temperature rise of respective conductors, the 70 ℃ of PVC insulated electric conductors of take are example, and its safe current is as table 1 (the scape technology of passing away part) and table 2 (electrician's specification table 16-3).
Table 2 70CPVC insulated conductor tube seat safe current capacities chart (extraction)
By table 1 and table 2, can be found out, critical current density is 18A/mm
2～18.75Amm
2; The temperature rise of multiple conducting wires is greater than the temperature rise of a small amount of wire in same conduit in same conduit, thus the safe current capacity of wire because of temperature rise different.So the height of improvement conductor of the present invention and insulator structure is led in energy-saving cable:
1) the circular hollow insulator made from ambroin is placed separately between two stranded conductors, because hollow insulator easily dispels the heat, can promote ampacity, the insulating material of saving of work and time, and then minimizing again consumption;
2) the T shape hollow insulator made from ambroin is placed separately between two stranded conductors, can omit once stranded operation, strengthens again aeration-cooling effect, promotes ampacity, saves insulating material consumption;
3) strands conductor and T shape hollow insulator, or strands conductor and circular hollow insulator and T shape hollow insulator be spaced, and is looped around edge of circular hollow screw body week, is conducive to ventilate, and reduced temperature rise, thereby improved ampacity;
4) strands conductor and T shape hollow insulator, or strands conductor and circular hollow insulator and T shape hollow insulator are arranged at interval, and be overlapped into the high cable heart yearn of trapezoidal or fan-shaped multicore, when cause is twisted into circle, with the wheat of gum, draw stranded high cable heart yearn is rolled into one, therefore heart space just need to not set off with hollow screw body therein, both strengthened aeration-cooling effect, increase ampacity, saved again insulating material;
5) stranded conductor and circular hollow insulator or T shape hollow insulator are directly stranded, therefore do not need stranded conductor fixed mount punching (having used conductor fixed mount in the patent that is 201110318158X at application number), save man-hour, remove from again the operation in stranded conductor embedded conductor fixed mount;
(2) wire of application critical current density is led the conductor of energy-saving cable as height
From table 1, learn 1.0mm
2safe current be 18A, be also critical current density.Thereby the invention reside in the ampacity saving copper material resource that improves conductor, and then reach the object of carbon reduction, therefore high cable conductor adopts the wire of critical current density, after insulation, with parallel way and binding post, follow respectively, just can reach the effect that height is led ampacity.
(3) expand the function of kelvin effect
As everyone knows, when electric charge transmits in conductor, its current density is unequal distribution shape, and the current density that more approaches conductor week edge is larger, otherwise less.Although different with regard to excuse between Ohm's law, faraday's rule or kelvin effect three, if digest, realize wherein reason or have new discovery: temperature rise determines ampacity, and rated temperature-rise is directly proportional to ampacity; The girth of conductor is directly proportional to ampacity, if area is constant, its ampacity increases because of conductor girth, otherwise if girth is constant, area reduces, and its ampacity is still constant.
For example,, with critical current density 1.0mm
2/ 18A is example: known 1.0mm
2 the girth of conductor is 3.545mm, modern by 1.0mm
2wire be divided into 7 equal portions, the diameter of every wire is
again by 7
conductor be twisted into one; Or 6
conductor be twisted into one, of its center is copper-clad aluminum conductor or the copper covered steel wire of same core circle.Both girths are 4.024mm (d π n/2) equally; But with regard to conductor area speech, the former is 1.0mm
2and the latter is 0.86mm
2.By above-mentioned 1.0mm
2and 0.86mm
2sample, respectively get one section and do respectively temperature rise test (setting 65 ℃ of temperature rises), after 4 hours, when temperature stabilization is during at 65 ℃ ± 1 ℃, both ampacitys are all 20A.So, known in above-mentioned case:
1) 1.0mm
2or 0.86mm
2when identical temperature rise, its ampacity is all 20A, but 0.86mm on area
2compare 1.0mm
2little, so proof " girth is constant, and its ampacity of area reducing is constant ";
2) known single 1.0mm
2 the girth of conductor is 3.545mm, but 7
stranded, one of its center is copper-clad aluminum conductor or copper covered steel wire, and the girth of this stranded conductor is 4.024mm, compares 1.0mm
2girth increased 0.474mm, so ampacity also increased 2A, so provable " if conductor area is constant, increase ampacity increase because of conductor girth ".
Again for example: with regard to traditional electric wire 6mm
2with high cable 3mm
2for example: when identical temperature rise, its ampacity is all 50A.6mm
2traditional electric wire normally with single
copper cash is conductor, and girth is 8.67mm (d π); High cable be by
copper cash forms, and its girth is 14.08mm (d π n/2), than traditional wire conductor Zhou Chang great.So, known in above-mentioned case:
1) due to traditional electric wire, fail fully to apply the function of critical current density, be limited by again the constraint of kelvin effect, therefore fail to give full play to the due ampacity of conductor area;
2) so can prove, application critical current density can expand kelvin effect, also promotes ampacity, relative also saving copper material simultaneously.
So the present invention adopt by many conductors, be stranded in same core circle or non-same core circle heart yearn week as height, lead the conductor of energy-saving cable along making stranded conductor, thereby increased its girth for the long-pending conductor of same cross-sectional, the ampacity of unit are has been increased, and then make copper material give full play to guide functions, saved copper material, useful to energy-conserving and environment-protective.
3. beneficial effect
Adopt technical scheme provided by the invention, the known techniques having with habit is compared, and has following remarkable result:
(1) stranded conductor is made on the week edge that the present invention adopts multiple conducting wires to be stranded in same core circle or non-same core circle heart yearn, and conductor area is minimized, and kelvin effect maximizes, and has promoted the ampacity of conductor area, can save copper material approximately 50%～70%;
(2) the circular hollow insulator that the present invention makes with ambroin is placed separately between two stranded conductors, has both insulated aeration-cooling, promotes ampacity, the insulating material of saving of work and time, and then minimizing again consumption;
(3) the T shape hollow insulator that the present invention makes with ambroin is placed separately between two stranded conductors, can omit once stranded operation, again can be aeration-cooling, promote ampacity, and save insulating material consumption;
(4) strands conductor and T shape hollow insulator in the present invention, or strands conductor and circular hollow insulator and T shape hollow insulator are arranged at interval, be looped around edge of circular hollow screw body week, both saved insulating material, be conducive to again ventilate, reduce temperature rise, thereby improved ampacity;
(5) strands conductor and T shape hollow insulator in the present invention, or strands conductor and circular hollow insulator and T shape hollow insulator are spaced, and be overlapped into the high cable heart yearn of trapezoidal or fan-shaped multicore, when cause is twisted into circle, with the wheat of gum, draw stranded high cable heart yearn is rolled into one, remove from office except when cable core is in prison in process, often because wheat drawstring is loose, must shut down the drawback of repairing, simultaneously, heart space just need to not set off with hollow screw body therein, both strengthened aeration-cooling effect, increase ampacity, save again insulating material,
(6) the present invention has saved insulating material use amount in a large number, makes height lead energy-saving cable lightweight, easily construction carrying;
(7) central part at its two ends is provided with groove ring along being provided with groove the week of hollow channels doublet of the present invention, and be conducive to stranded conductor and embed groove, then pressing and making stranded conductor be bending at groove ring place through terminal, thereby firm difficult drop-off.
