Description
Technical field
The utility model relates to the technical field of cable, specifically a kind of new forms of energy cable, particularly relates to a kind of cable utilizing wind energy.
Background technology
In recent years, along with rising steadily of the traditional energy such as coal, oil price, people turn to hope the development of new forms of energy day by day, and these new forms of energy comprise solar energy, wind energy, biomass energy, geothermal energy and oceanic energy etc.
Wind-powered electricity generation industry development obtains like a raging fire, has expedited the emergence of the demand to cable for wind power generation.Due to the bad environments of wind power generation, blower fan is longer for service life, and cable constantly rotates with blower fan, also very high to the performance requirement of cable, dependence on import always now, expensive, existing wind energy cable in use simultaneously, severe due to environment for use, easily causes bending disconnected core event often to occur, tension and bending resistance poor.
Summary of the invention
The purpose of this utility model is the wind energy cable providing a kind of improvement, and it can overcome wind energy cable dependence on import in prior art, price is higher, bending disconnected core, the some shortcomings of tension and bending resistance difference.
To achieve these goals, the technical solution of the utility model is: a kind of wind energy cable, it is characterized in that: described wind energy cable is made up of surrounding layer and inner core, inner core is made up of four cable cores, be provided with the first high temperature resistant slippage band between cable core and surrounding layer, between cable core and slippage band, between adjacent cable core, be extruded with packed layer.
During use, wind energy cable described in the utility model adds the flexibility of conductor, like this, electric cable for coal mining machine in use wind energy cable is convenient to bending flexible, make the power put on wind energy cable, can be cushioned because of the flexibility of the elasticity of rubber bedding core and wind energy cable, thus fundamentally be solved the difficult problem that wind energy cable bends disconnected core.The Relative sliding arranging increase wind energy cable of slippage band, enables wind energy cable when stressed, obtain certain buffering, thus increases the useful life of wind energy cable.When cross-sectional area of conductor is constant, be the intensity improving wind energy cable conductor, we add not only soft but also have the fiber material of higher-strength in the conductor, and adopt the structure that tangles again, thus improve tension and the bending resistance of conductor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Label in accompanying drawing is expressed as follows: 1 sheath, 2 first high temperature resistant slippage bands, 3 packed layers, 4 second high temperature resistant slippage bands, 5 insulating barriers, 6 conductors and high strength fibre band.
A kind of wind energy cable described in the utility model, its difference with the prior art is: described wind energy cable is made up of surrounding layer and inner core, inner core is made up of four cable cores, the first high temperature resistant slippage band is provided with between cable core and surrounding layer, be extruded with packed layer between cable core and the first high temperature resistant slippage band, between adjacent cable core, packed layer adopts chlorinated polyethylene sheath material.Surrounding layer adopts chlorinated polyethylene sheath, chloroprene rubber sheath or chlorosulfonated polyethylene sheath to make, and the thickness of surrounding layer is 1.4-7.7mm.
Described cable core is wrapped up successively by conductor, insulating barrier and the second high temperature resistant slippage band and forming, and is surrounded with high strength fibre band between conductor and insulating barrier.
Conductor adopts the 5th kind or the 6th kind of zinc-plated soft copper conductor in GB/T 3956, lay configuration adopts and twists pattern again, described multiple strand pattern can reduce the line diameter of wind energy cable conductor, increase single line radical, add not only soft but also have the fiber material of higher-strength in conductor simultaneously, thus flexibility and the intensity of wind energy cable conductor can be increased.Insulating barrier adopts ethylene-propylene rubber or silicon rubber to make, and the thickness of insulating barrier is 0.8-3.0mm.
In enforcement, due to the bad environments of wind power generation, and cable constantly rotates with blower fan, therefore has special requirement to the construction of cable, considers emphatically following problem during design.(1) flexibility of structure.In order to reach the flexibility of the construction of cable, the 5th kind or the 6th kind of zinc-plated soft copper conductor that we select GB/T 3956 to specify, and strand structure is optimized design, to guarantee the softness of cable.(2) environment for use of cable.Due to the environment for use very severe of cable, so for insulated part, insulation adopts ethylene-propylene rubber or silicon rubber, has excellent resistance to ozone and heat aging property; And for outermost sheath, adopt haloflex, neoprene or chlorosulfonated polyethylene, there is oil resistance and cold tolerance.
Advantage of the present utility model is as follows:
1. increase the flexibility of wind energy cable
(1) increase the flexibility of wind energy cable conductor: under the condition that cross-sectional area of conductor is constant, reduce the line diameter of wind energy cable conductor, increase single line radical, and employing twists pattern again, thus flexibility and the intensity of wind energy cable conductor can be increased.
(2) flexibility of wind energy cable is increased: for increasing the flexibility of wind energy cable, at the rubber bedding core that the placement cross section, center of wind energy cable stranding is larger, adopt less laying up pitch simultaneously, like this, electric cable for coal mining machine in use wind energy cable is convenient to bending flexible, make the power put on wind energy cable, can be cushioned because of the flexibility of the elasticity of rubber bedding core and wind energy cable, thus fundamentally solve the difficult problem that wind energy cable bends disconnected core.
2. increase the Relative sliding of wind energy cable
First at the outer high temperature resistant slip band of wrapped one deck of single wind energy cable, then the high temperature resistant slip band of wrapped one deck again when the overall twisted synthesizing cable of wind energy cable, increase the Relative sliding of wind energy cable, enable wind energy cable when stressed, obtain certain buffering, thus increase the useful life of wind energy cable.
3. increase the intensity of wind energy cable conductor
When cross-sectional area of conductor is constant, be the intensity improving electric cable for coal mining machine wind energy cable conductor, we add not only soft but also have the fiber material of higher-strength in the conductor, and adopt the structure that tangles again, thus improve tension and the bending resistance of conductor.
