Abstract
The invention relates to a three-phase alternating current power cable. The three-phase alternating current power cable consists of a zero line conductor (1), a rubber skeleton (2), a zero line insulating layer (3), a phase line conductor (4) and a phase line insulating layer (5); three phase lines are arranged in an equilateral triangle shape, a zero line is arranged at the central part, the distances between among the three phase lines and the distances between the three phase lines to the relative zero line are equal, three-phase alternating current alternating waveforms are the same, a magnetic field is closed inside the cable, electromagnetic waves are not leaked, the line loss is low, and the damages such as power grid waveform distortion and three-phase voltage unbalance can also be inhibited at the same time; and due to the fact that isolation for the rubber skeleton is arranged between every cable core, the damage that the conductor insulating layer is damaged under the effect of external force is reduced. The three-phase alternating current power cable can be widely applied to electric power systems such as factories, offices and residential areas, so that the alternating circuit electromagnetic interface is reduced, the three-phase power supply phase angle is balanced, the utilization rate of the system is improved, and the purposes of energy saving and safe operation are reached.
Description
Technical field
The invention belongs to electric power facility category, relate to a kind of cable, be related specifically to a kind of three-phase ac power cable。
Background technology
Traditional three-phase ac power cable is that three phase lines and a zero line are directly arranged stranded shape all-in-one-piece toroidal cores, and does not meet alternating current circuit waveform alternating rule, and line loss is relatively big, interference damage is big, simultaneously opposing exterior mechanical infringement ability。High-power impact load, the widely using of rectification frequency modulation equipment is developed rapidly with society's industry, the harm such as the line voltage causing system fluctuates, flickering, wave distortion, have a strong impact on power equipment, the safety of electric equipment and three-phase imbalance, idle power consumption increase, and the interference etc. of the facilities such as communication is endangered by power circuit, therefore in electrical network, the magnetic field balance of power circuit is most important to improving power supply quality, raising the whole network economic benefit and safety。Due to the stranded loop configuration arrangement of 4 cores of conventional power cable, 3 phase phase lines each other and relatively distance between zero line not etc., the unbalanced shortcoming of three-phase magnetic loop, cause cable run leakage field phenomenon, other weak electric signals such as communication are produced interference, and increases the situation of line loss;Additionally, due to conventional power cable core directly arranges stranded, between core, be not provided with physical separation, be easy under external force produce insulation damages and short-circuit。The invention provides a kind of ac power cable, the arrangement architecture of its 3 phase phase line be equilateral triangle, and centre arranges zero line, between 3 phases and the distance of relative zero line equal, 3 cross streams magnetic fields can close inside cable, will not produce electromagnetic exposure phenomenon;Between each core, rubber skeleton is set, core insulating barrier is played a protective role。
Summary of the invention
One three-phase ac power cable of the present invention, main neutral conductor (1), rubber skeleton (2), zero line insulating barrier (3), phase conductor (4), phase line insulating layer (5) form;It is characterized in that: neutral conductor (1) is arranged on middle, surface parcel zero line insulating barrier (3), the arranged outside rubber skeleton (2) of zero line insulating barrier (3), the outside of rubber skeleton (2) is that equilateral triangle arranges three phase conductor (4), surface parcel phase line insulating layer (5) of every phase conductor (4) forms wire harness, wraps up belting layer (6), inner restrictive coating (7), armor (8), external sheath layer (9) successively on wire harness surface。
Described neutral conductor (1) and phase conductor (4) structure adopt one of solid conductor, stranded conductor and flexible conductor, material selection annealed copper wire, aluminum and aluminium alloy one therein。
It is the fan shape of 120 degree that described phase conductor (4) is squeezed into angle。
Described rubber skeleton (2) is a rubber tube surface is 120 degree of longitudinally laying three slat gums partitions。
One three-phase ac power cable of the present invention, three phase lines are that equilateral triangle is arranged, centre arranges zero line, the distance of three phase lines each other and relatively zero line is equal, consistent with three-phase alternating current alternation waveform, magnetic field closes inside cable, No leakage electromagnetic wave, line loss is low, waveform distortion of the power supply network, imbalance of three-phase voltage etc. can also be suppressed to endanger simultaneously;Owing to all there being the isolation of rubber skeleton between each core, reduce the harm because damaging insulating layer of conductor under External Force Acting。The present invention can extensively send out in power systems such as being applied to factory, office, residential block, reduces alternating current circuit electromagnetic interference, balance three phase mains phase angle, improves system interest rate, reaches energy-conservation and safe operation purpose。
