Abstract
The utility model discloses parallel photovoltaic cable of two compound cores of easy tear type optic fibre has photovoltaic cable body, photovoltaic cable body includes and is equipped with temperature measurement optical fiber between two parallel arrangement's the transmission heart yearn by two parallel arrangement's transmission heart yearn, and temperature measurement optical fiber passes through the easy tear connector and is connected with two transmission heart yearns, the transmission heart yearn has a core wire conductor, core wire conductor from inside to outside in proper order the cladding have insulating layer, easy tear layer and restrictive coating, the utility model discloses electric energy that can a plurality of solar cell panel of simultaneous transmission, effective electrical energy conversion is rateed highly, again simple to operate to through the temperature measurement optical fiber temperature variation, can accurately fix a position the position that the cable probably takes place the short circuit, play early warning function.
Description
Technical field
The utility model is related to photovoltaic cable, more particularly, to 1.8KV voltages and following solar energy photovoltaic system, is used for
Transmission electric energy photovoltaic cable parallel with compound two cores of a kind of easy tearing mode optical fiber of thermometric.
Background technology
Two core cable is once cable can all generate heat before short circuit or open circuit, and temperature is apparently higher than normality temperature, and existing at present
, without temperature-measuring optical fiber, cable once breaks down and cannot quickly find, and can not reach for some single-core cables and two core photovoltaic cables
To the effect for giving warning in advance.
The content of the invention
The purpose of this utility model is aiming at disadvantage mentioned above and is improved, there is provided a kind of simple installation, improves solar energy
Installation effect of system, is placed by temperature-measuring optical fiber, can carry out the easy of on-line monitoring to the ruuning situation of photovoltaic cable
The tearing mode optical fiber parallel photovoltaic cable of compound two cores.
The easy tearing mode optical fiber of the utility model parallel photovoltaic cable of compound two cores, it is characterised in that：With photovoltaic cable sheet
Body, the photovoltaic cable body include two transmission heart yearns arranged in parallel, are provided between two transmission heart yearns arranged in parallel
Temperature-measuring optical fiber, temperature-measuring optical fiber are connected with two transmission heart yearns by easily tear connector, and the transmission heart yearn has cored wire conductor,
Cored wire conductor is coated with insulating barrier, easy tearing layer and restrictive coating from inside to outside successively.
The cored wire conductor is formed using the tin plating soft copper conductor strands of no more than 0.3mm.
The insulating barrier and restrictive coating are made using 125 degree of low smoke, zero halogen polyolefin insulation material, and its thickness is not less than
0.5mm。
The easy tearing layer is made using talcum powder.
The use range of the temperature-measuring optical fiber is at -60 DEG C～150 DEG C.
The utility model can be high with the electric energy of the multiple solar panels of simultaneous transmission, effective energy conversion rate, installs again
It is convenient, and by temperature-measuring optical fiber temperature change, can the position that may be short-circuited of precise positioning cable, play forewarning function.
Description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1- transmits heart yearn, and 2- temperature-measuring optical fibers, 3- easily tear connector, and 4- cored wire conductors, 5- insulating barriers, 6- easily tear
Parting, 7- restrictive coatings.
Specific embodiment
Referring to Fig. 1, the easy tearing mode optical fiber of the utility model parallel photovoltaic cable of compound two cores, with photovoltaic cable body,
The photovoltaic cable body includes two transmission heart yearns 1 arranged in parallel, is provided with survey between two transmission heart yearns arranged in parallel
Warm optical fiber 2, temperature-measuring optical fiber are connected with two transmission heart yearns by easily tear connector 3, and the transmission heart yearn has cored wire conductor
4, cored wire conductor is coated with insulating barrier 5, easy tearing layer 6 and restrictive coating 7 from inside to outside successively；The cored wire conductor is adopted and is not more than
The tin plating soft copper conductor strands of 0.3mm are formed, and softness increases, it is adaptable to the less place of bending radius, effectively prevents from leading
Body is aoxidized, and significantly extends the service life of cable；The insulating barrier and restrictive coating adopt 125 degree of low smoke, zero halogen polyolefin
Insulation Material is made, and its thickness is not less than 0.5mm, with good insulaion resistance performance and ultraviolet-resistant performance；And have very wide
Use temperature（- 40 DEG C～120 DEG C）, cable life can be made to reach 25 years；The easy tearing layer is made using talcum powder, mainly
Composition is the aqueous magnesium silicate of talcum, and molecular formula is Mg3 [Si4O10] (OH) 2, with lubricity, it is anti-stick, help stream, fire resistance,
Acid-resisting, insulating properties, fusing point be high, chemically torpescence, covering power be good, softness, good luster, the absorption affinity excellent physics such as by force
Performance, can make insulating barrier and restrictive coating adhesion；The use range of the temperature-measuring optical fiber at -60 DEG C～150 DEG C, abrasion-resistant,
Corrosion-resistant, not hydrophilic, not oleophylic, can be used in extensive chemical environment for a long time.
