The multi-core photovoltaic flexible cable used for the microinverter comprises a plurality of conductors, insulation layers and sheaths. The conductors wrapped by the insulation layers are mutually stranded to form cable cores wrapped by the sheaths which are irradiation-crosslinking low-smoke zero-halogen polyolefin sheaths. Compared with the prior art, the multi-core photovoltaic flexible cable for the photovoltaic microinverter has the advantages of good insulation, sunlight resistance, ozone resistance, acid and alkali resistance, high flame retardancy and the like as the sheaths are made of irradiation-crosslinking low-smoke zero-halogen polyolefin.
Description
Technical field
The utility model relates to the little inverter of a kind of photovoltaic multicore photovoltaic flexible cable.
Background technology
Electric power is the backbone of modern industrial society.In visible future, electricity also is one of leading role of green science and technology.Electric energy is easy to be converted into the energy of other form, and therefore the purposes of electricity is quite extensive.The figure that electricity is arranged in the fields such as for example, traffic, heating, illumination, communication, calculating.
In order to obtain electric power, people have built various power plants and have generated electricity, for example: thermal power generation, hydroelectric power generation, wind power generation etc.At present, thermal power generation is topmost generation mode.But thermal power generation mainly is to utilize fossil fuels such as coal, oil.Can produce gases such as sulfur dioxide, nitrogen dioxide after coal, the oil combustion, these gases can cause acid rain, contaminated environment.In addition, fossil fuel is non-renewable resources, therefore need tap a new source of energy to satisfy human wants.
Solar energy refers to the emittance of sunlight.Its aboundresources both can freely use, and need not transportation again, and environment is not had any pollution yet, was a kind of clean energy resource.Therefore, solar energy is one of desirable energy of generating electricity of human use.For this reason, people have developed a kind of solar module that can utilize solar energy to generate electricity, this solar module be a kind of have encapsulation and inner connect, can provide separately direct current output, indivisible minimum solar battery group attaches together and puts.Some described solar module series, parallel are connected the back just can form the needed voltage of people or electric current.But what described solar module was exported is direct current, and employed electricity is alternating current in the daily life, therefore needs to use the miniature inverter of photovoltaic that direct current is converted into alternating current.Miniature inverter can be realized MPPT maximum power point tracking in the panel level, has the advantage that surmounts central inverter.Can be optimized by the power output to each solar module like this, make whole power output maximize.At present, use the cable on little inverter to adopt polyvinyl chloride as insulating sleeve.But, this material non-refractory, the heat that is produced by high temperature easily in the course of processing is scalded distortion.And this material contains halogen, can discharge hydrogen chloride and other toxic gas in combustion process, thus contaminated environment.
In view of the above problems, be necessary to provide a kind of cable for little inverter, to address the above problem.
The utility model content
At the deficiencies in the prior art, the technical problem that the utility model solves provides the little inverter of a kind of photovoltaic with multicore photovoltaic flexible cable, and the little inverter of this photovoltaic has good insulating, anti-daylight, anti-ozone, acid and alkali-resistance, high flame retardant, advantage such as nontoxic with multicore photovoltaic flexible cable.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
The little inverter of a kind of photovoltaic multicore photovoltaic flexible cable, be used for miniature inverter, the insulating barrier and the sheath that comprise some conductors, the described conductor of coating, the described mutual stranded formation cable core of some conductors that is coated with insulating barrier respectively, the outside of described cable core is coated with described sheath, and described sheath is the irradiated crosslinking low-smoke and halogen-free polyolefin jacket.
Further, described insulating barrier is the irradiated crosslinking low-smoke and halogen-free polyolefin insulation layer.
Further, described conductor is by mutual stranded formation of some leads.
Further, described lead is copper wire.
Further, described conductor is three.
The beneficial effects of the utility model are: compared to prior art, because described sheath adopts the irradiated crosslinking low-smoke and halogen-free polyolefin to make, thereby makes the little inverter of the utility model photovoltaic have advantages such as good insulating, anti-daylight, anti-ozone, acid and alkali-resistance, high flame retardant with multicore photovoltaic flexible cable.
Description of drawings
Fig. 1 is the little inverter of the utility model photovoltaic multicore photovoltaic soft cable structure schematic diagram.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments the utility model is described in detail.
See also shown in Figure 1ly, the little inverter of the utility model photovoltaic is used for the miniature inverter of photovoltaic with multicore photovoltaic flexible cable 100, comprises some conductors 10, insulating barrier 20 and sheath 30, and the outside of every conductor 10 is coated with described insulating barrier 20.Described conductor 10 is by some leads 11 stranded forming, thereby can improve the pliability of described conductor 10.In the present embodiment, described conductor 10 is three, and described lead 11 is copper wire, but the quantity of described conductor 10 is unrestricted, and the quantity of described conductor 10 can be set as the case may be flexibly.Some conductor 10 mutual stranded formation cable cores that are coated with described insulating barrier 20, the outside of described cable core is coated with described sheath 30.Described insulating barrier 20 and described sheath 30 adopt the irradiated crosslinking low-smoke and halogen-free polyolefin to make, and described irradiated crosslinking low-smoke and halogen-free polyolefin has advantages such as good insulating, anti-daylight, anti-ozone, acid and alkali-resistance, high flame retardant.
Compared to prior art, because described insulating barrier 20 and described sheath 30 adopt the irradiated crosslinking low-smoke and halogen-free polyolefin to make, thereby make the little inverter of the utility model photovoltaic have advantages such as good insulating, anti-daylight, anti-ozone, acid and alkali-resistance, high flame retardant with multicore photovoltaic flexible cable 100.
It may be noted that especially that for the person of ordinary skill of the art that does changes at equivalence of the present utility model under instruction of the present utility model, must be included in the scope that the utility model claim advocates.
