Muchidimbu, photovoltaic cable inobatsira zvikuru. Ndeyekutumira, kubatanidza, uye kutonga masisitimu emagetsi. Yakavimbika, idiki, uye yakachipa. Simba rayo rekufambisa rakagadzikana. Zviri nyore kuisa nekuchengetedza. Kushandiswa kwaro kunoshanda uye kwakachengeteka kupfuura PVC waya nekuda kwenzvimbo yayo uye kutapurirana kwemagetsi.
14. Chengetedzo
Photovoltaic cables haifaniri kuiswa pamusoro. Vanogona kuva, kana simbi yesimbi yakawedzerwa.
Photovoltaic cables haafaniri kunge ari mumvura kwenguva yakareba. Dzinofanirwawo kuchengetedzwa kunze kwenzvimbo dzine hunyoro nekuda kwezvikonzero zvebasa.
3) Photovoltaic cables haifaniri kuvigwa zvakananga muvhu.
4) Shandisa zvakakosha photovoltaic connectors ye photovoltaic cables. Nyanzvi dzemagetsi dzinofanirwa kudziisa.
15. Zvinodiwa:
Low-voltage DC transmission tambo mu solar system dzine zvakasiyana zvinodiwa. Dzinosiyana nekushandiswa kwechikamu uye zvinodiwa zvehunyanzvi. Zvinhu zvinofanirwa kutariswa ndezvekuvharisa tambo, kudzivirira kupisa, uye kuramba kwemoto. Zvakare, kuchembera kwakanyanya uye waya dhayamita.
DC tambo dzinowanzoiswa kunze. Dzinofanirwa kuve humbowo hunopesana nehunyoro, zuva, kutonhora, uye UV. Naizvozvo, tambo dzeDC mune dzakagoverwa photovoltaic masisitimu dzinoshandisa tambo dzakakosha. Ivo vane photovoltaic certification.
Mhando iyi yekubatanidza tambo inoshandisa kaviri-layer insulation sheath. Iyo ine yakanakisa kuramba UV, mvura, ozone, asidhi, uye munyu. Iyo ine zvakare yakakura-yese-mamiriro ekunze kugona uye kupfeka kuramba.
Funga nezvemagetsi eDC uye zvinobuda zvePV mapaneru. Iyo inowanzoshandiswa PV DC tambo ndeye PV1-F1 * 4mm2, PV1-F1 * 6mm2, nezvimwe.
16. Sarudzo:
Iwo tambo dzinoshandiswa mune yakaderera-voltage DC chikamu che solar system. Vane zvakasiyana zvinodiwa. Izvi zvinodaro nekuda kwekusiyana kwenzvimbo dzekushandisa. Zvakare, izvo zvinodiwa zvehunyanzvi zvekubatanidza zvikamu zvakasiyana. Unofanira kufunga zvinhu zvishomanana. Izvi ndezvi: cable insulation, kupisa kupisa, moto kuramba, kuchembera, uye waya dhayamita.
Zvinodiwa chaizvo ndezvizvi:
Iyo tambo pakati pe solar cell modules inowanzobatanidzwa zvakananga. Ivo vanoshandisa tambo yakasungirirwa kune module's junction box. Kana urefu husina kukwana, tambo yakakosha yekuwedzera inogona kushandiswa.
Tambo ine zvirevo zvitatu. Izvo ndezvemamodules emhando dzakasiyana dzesimba. Ivo vane mhiri-chikamu nzvimbo ye2.5m㎡, 4.0m㎡, uye 6.0m㎡.
Iyi mhando yetambo inoshandisa kaviri-layer insulation sheath. Inopikisa ultraviolet mwaranzi, mvura, ozone, asidhi, uye munyu. Inoshanda zvakanaka mumamiriro ekunze ese uye haipfeki.
Iyo tambo inobatanidza bhatiri kune inverter. Inoda akawanda-strand akapfava waya dzakapfuura iyo UL bvunzo. Waya dzinofanirwa kubatanidzwa sepedyo sezvinobvira. Kusarudza tambo pfupi uye dzakakora kunogona kucheka kurasikirwa kwehurongwa. Inogonawo kuvandudza kushanda uye kuvimbika.
Iyo tambo inobatanidza bhatiri array kune controller kana DC junction bhokisi. Inofanira kushandisa UL-yakaedzwa, yakawanda-strand yakapfava waya. Nharaunda yewaya yepakati-chikamu inoteera array's yakanyanya kubuda ikozvino.
Iyo DC tambo nzvimbo inoiswa zvichienderana nemisimboti iyi. Aya tambo anobatanidza solar cell modules, mabhatiri, uye AC mitoro. Yavo yakayerwa ikozvino ndeye 1.25 nguva yavo yakawanda yekushanda ikozvino. Iwo tambo dzinoenda pakati pe solar arrays, mapoka ebhatiri, uye inverters. Iyo tambo yakayerwa ikozvino ndeye 1.5 times yayo max kushanda ikozvino.
17. Kusarudzwa kwe photovoltaic cables:
Muzviitiko zvakawanda, tambo dzeDC dziri mu photovoltaic magetsi zviteshi ndezvekushandisa kwenguva refu kunze. Mamiriro ekuvaka anoderedza kushandiswa kwezvibatanidza. Iwo anonyanya kushandiswa kubatanidza tambo. Cable conductor zvinhu zvinogona kukamurwa kuita copper core uye aluminium musimboti.
Copper core cables ane akawanda antioxidants kupfuura aluminium. Izvo zvakare zvinogara kwenguva refu, zvakanyanya kugadzikana, uye zvine mashoma voltage kudonha uye kurasikirwa kwemagetsi. Mukuvaka, cores yemhangura inoshanduka. Vanobvumira kubhenda kudiki, saka zviri nyore kutendeuka uye shinda. Copper cores inodzivisa kuneta. Hazviputsika nyore mushure mekukotama. Saka, wiring iri nyore. Panguva imwecheteyo, mhangura yemhangura yakasimba uye inogona kumira kushushikana kwakanyanya. Izvi zvinoita kuti kuvaka kuve nyore uye kunoita kuti michina ishandiswe.
Aluminium core cables akasiyana. Ivo vanojaira kune oxidation panguva yekuiswa nekuda kwealuminum's chemical properties. Izvi zvinoitika nekuda kwekukambaira, chivakwa chealuminium chinogona kukonzera kukundikana nyore.
Naizvozvo, aluminium core cables dzakachipa. Asi, kuitira kuchengetedza uye kushanda kwakasimba, shandisa copper core cables mumapurogiramu e photovoltaic.
