Description
Technical field
The utility model belongs to electrical power distribution field technical field of electric wires and cables, and in particular to a kind of novel conductive wire.
Background technique
With the rapid economic development in our country, the obvious quickening of process of modernization, the continuous expansion of city size and
The fast development of new countryside construction, electricity needs rapid growth.It is anxious and due to the imbalance of energy source distribution and the western and eastern's development
It need to solve that the energy is high-power, bottleneck problem of long distance delivery.Although the construction parts of super-pressure alleviate this contradiction, by
It is formed on the limitation of traditional steel-cored aluminium strand bearing capacity, transmission line of electricity can't bear to bear the demand of the quick dilatation of transmission capacity, electricity
Power transmission becomes " bottleneck " of electric power industry development.
The common steel-cored aluminium strand of ACSR, defect: being unable to hot operation, limits the capacity of conducting wire, and current-carrying capacity is limited;Steel core
Weight, thermal expansion coefficient is big, and hot arc sag is big;Energy conservation is needed by big conducting wire, and conducting wire itself is very heavy, needs higher steel tower, engineering at
This height.
Carbon-fibre wire use carbon fibre composite intensity is high, light-weight, small characteristic of expanding with heat and contract with cold, instead of general
Steel core in admittance line is as load core material.Carbon fibre composite used is round bar type structure, can be coarse to fine, can be
Single (U.S. CTC or Europe Nexans) or multiply (found steel processed or American South line in east), the increasing in carbon fiber composite material core
Strong fiber can also include glass fibre and similar reinforcing fiber in addition to carbon fiber, basis material include thermoplastic plastic or
Thermosetting resin.Because carbon fibre composite load core intensity is high, carbon-fibre wire generally makees conducting medium using soft aluminium of annealing,
Aluminium alloy or duralumin can also be used.Carbon-fibre wire, energy-saving and emission-reduction, the common steel-cored aluminium strand of current density ratio increase by 30%,
Line loss reduces 30%, and associated with line loss is that carbon dioxide caused by power generation can reduce 30%.Its defect: wire stylet is used
Glass and carbon-fiber composite material are done, and the modular ratio steel core of load core is much smaller, form biggish ice formation arc sag, Great span and
Big conducting wire is because be self-possessed, or because of icing, the load of windage etc forms big arc sag, and pylon is caused to increase or increase electricity
Tower reduces tower away from engineering cost increases;The voltage endurance capability of load core is insufficient, and when radial pressure, easily division damage need to use valuableness
Dedicated fitting;When bending, load core especially carbon fiber load core is easy to lose because of remaining stress;Composite wood
Material is exposed to environment, and service life is affected by environment larger, the especially serious destruction of aquation and oxygenolysis to composite core.
Carbon-fibre wire had been widely recognized and applies in past ten years, and carbon fiber load core has minimum
Thermal expansion coefficient, so its hot arc sag very little more than hot inflection point, the running temperature of current-carrying can achieve 200 DEG C,
Its current-carrying capacity is also much better than conventional wires, light-weight because its intensity is high, corrosion-resistant equal good characteristics, gradually now
Begin with the trend instead of traditional steel-cored aluminium strand.
However, the hot inflection temperature of its carbon fiber load core is greater than 70 DEG C, therefore in the temperature hereinafter, the elongation of conducting wire
It is still determined by aluminum stranded conductor, there are biggish hot arc sags.Carbon-fibre wire is compared to conventional wires, complicated construction technique and peace
Need special fitting when dress, in certain project costs, construction and fitting cost can account for the one third of project cost
More than.Meanwhile the risk of construction is larger, carbon fiber load core is easy to break, in the construction process, if encountering wedge angle, load core meeting
By excessive axial force, it may occur that damage, if load core is only by partial injury, wire fracture may postpone some months even
Several years, seriously threaten the safety and reliability of power grid." lantern " problem occurred in construction is also the one of carbon-fibre wire
Big drawback.Carbon-fibre wire is because without carrying out overtension pretreatment, and arc sag changes greatly after construction and installation, and at random not
It is predictable, it is a major challenge to the later maintenance after construction.With the project implementation of high pressure extra-high voltage and some DC terms purposes
Pilot, carbon-fibre wire develops towards more heavy in section target always, and more heavy in section conducting wire, the bending of strengthening core are always
One big problem.
The aluminum matrix composite of ceramic fibre enhancing is also used successfully to substitution steel core as compound wire by Minnesota Mining and Manufacturing Company
Load core (ACCR conducting wire).Such conducting wire generally uses the small mandrel structure of multiply, and necessity to realize plug and conducting wire is soft
Property.Because the elongation strain of ceramic fibre is extremely limited, though ceramic fibre conducting wire using the small round wires of multiply, with carbon-fibre wire class
Seemingly, when meeting with sharp bend, it is still easy to damage broken string, causes huge security risk.
