Ka ntshetsopele e potlakileng ya lefatshe ka bophara ya ditsamaiso tsa tlhahiso ya motlakase wa photovoltaic (PV), dithapo tsa photovoltaic (dithapo tsa PV)—jwalo ka dikarolo tsa bohlokwa tse hokahanyang di-module tsa PV, di-inverter, le mabokose a kopanyo—di bapala karolo ya bohlokwa polokehong yohle le bophelong ba tshebeletso ya setsi sa motlakase wa letsatsi. Ha di bapiswa le dithapo tsa motlakase tse tlwaelehileng, dithapo tsa photovoltaic di na le meralo e ikgethang haholo ya meaho le dikgetho tsa thepa ya cable.
1. Cable ea Photovoltaic ke eng?
Thapo ea photovoltaic, e tsejoang hape e le thapo ea letsatsi kapa thapo e ikhethileng ea PV, e sebelisoa haholo-holo litsing tsa motlakase tsa letsatsi, lits'ebetsong tsa photovoltaic tse ajoang, le lits'ebetsong tsa PV tse marulelong. Mefuta e tloaelehileng e kenyelletsa PV1-F le H1Z2Z2-K, tse lumellanang le maemo a machaba a kang EN 50618 le IEC 62930.
Kaha dithapo tsa PV di dula di pepesetswa dibakeng tse kantle, di tlameha ho sebetsa ka botshepehi tlasa dithempereichara tse phahameng, mahlasedi a matla a ultraviolet, dithempereichara tse tlase, mongobo le ho pepesehela ozone. Ka lebaka leo, ditlhoko tsa tsona bakeng sa thepa ya ho kwahela le thepa ya ho kwahela dithapo di phahame haholo ho feta tsa dithapo tse tlwaelehileng. Dibopeho tse tlwaelehileng di kenyeletsa ho hanyetsa dithempereichara tse phahameng le tse tlase, ho hanyetsa botsofadi ba UV bo botle, ho hanyetsa mafome ka dikhemikhale, ho dieha ha malakabe, botsoalle ba tikoloho, le bophelo ba tshebeletso bo rerilweng ba dilemo tse 25 kapa ho feta.
2. Liphephetso tsa Thepa ea Cable ho Litšebeliso tsa Photovoltaic
Litšebelisong tsa lefats'e la sebele, likhoele tsa photovoltaic hangata li kenngoa ka ho toba kantle. Mohlala, libakeng tsa Europe, mocheso o potolohileng oa litsamaiso tsa PV o ka atamela 100°C tlas'a maemo a letsatsi. Ka nako e ts'oanang, likhoele li pepesetsoa mahlaseli a UV a nako e telele, ho feto-fetoha ha mocheso oa motšehare le bosiu, le khatello ea mechine.
Tlas'a maemo a joalo, likhoele tsa PVC tse tloaelehileng kapa likhoele tsa rabara tse tloaelehileng li ke ke tsa boloka ts'ebetso e tsitsitseng ea nako e telele. Esita le likhoele tsa rabara tse lekantsoeng bakeng sa ts'ebetso ea 90°C kapa likhoele tsa PVC tse lekantsoeng bakeng sa 70°C li kotsing ea ho tsofala ha insulation, ho petsoha ha sheath, le ho senyeha ha ts'ebetso ka potlako ha li sebelisoa lits'ebetsong tsa photovoltaic tsa kantle, e leng se khutsufatsang bophelo ba ts'ebeletso ea sistimi haholo.
3. Tshebetso ya Motheo ya Dikheibole tsa Photovoltaic: Disebediswa tse Ikgethang tsa ho Sireletsa le ho Sireletsa
Melemo ea bohlokoa ea ts'ebetso ea likhoele tsa photovoltaic e nkiloe haholo-holo ho tsoa metsoakong ea tsona ea ho thibela mocheso e ikhethileng ea PV le metsoako ea sheathing. Sistimi e ka sehloohong ea thepa e sebelisoang kajeno ke polyolefin e kopantsoeng ke mahlaseli, hangata e thehiloeng ho polyethylene ea boleng bo holimo (PE) kapa polyolefin tse ling.
Ka ho bonesoa ha mahlaseli a elektronike, liketane tsa limolek'hule tsa thepa li feta ho hokahanngoa, ho fetola sebopeho ho tloha ho thermoplastic ho ea ho thermoset. Ts'ebetso ena e eketsa haholo ho hanyetsa mocheso, ho hanyetsa botsofali, le ts'ebetso ea mechini. Lisebelisoa tsa polyolefin tse hokahaneng ka mahlaseli li lumella likhoele tsa photovoltaic ho sebetsa ka ho tsoelang pele ho 90–120°C, ha ka nako e ts'oanang li fana ka ho tenyetseha ho hoholo ha mocheso o tlase, ho hanyetsa UV, ho hanyetsa ozone, le ho hanyetsa ho petsoha ha khatello ea tikoloho. Ho phaella moo, lisebelisoa tsena ha li na halogen ebile li lumellana le tikoloho.
4. Papiso ea Sebopeho le Thepa: Likhoele tsa Photovoltaic khahlanong le Likhoele tse Tloaelehileng
4.1 Sebopeho le Lisebelisoa tse Tloaelehileng tsa Likhoele tsa Photovoltaic
Mokhanni: Mokhanni oa koporo ea annealed kapa mokhanni oa koporo ea makotikoti, o kopanyang motlakase o phahameng le ho hanyetsa mafome
Lera la ho Sireletsa: Motsoako oa ho Sireletsa oa polyolefin o hokahaneng le mahlaseli (thepa ea ho Sireletsa e ikhethileng ka cable ea PV)
Sekoahelo sa Sheath: Motsoako oa polyolefin o kopantsoeng ka mahlaseli, o fanang ka tšireletso ea kantle ea nako e telele
4.2 Sebopeho le Lisebelisoa tse Tloaelehileng tsa Likhoele tse Tloaelehileng
Mokhanni: Mokhanni oa koporo kapa mokhanni oa koporo ea makotikoti
Lera la ho kenya lintho ka hare: Motsoako oa ho kenya lintho ka hare oa PVC kapaXLPE (polyethylene e hokahaneng)motsoako oa ho thibela mocheso
Lera la Selateng:PVCmotsoako oa ho koahela
5. Liphapang tsa Tshebetso tsa Motheo tse Bakiloeng ke Khetho ea Lintho
Ho ya ka pono ya mokhanni, dithapo tsa photovoltaic le dithapo tse tlwaelehileng di tshwana haholo. Dipharologanyo tsa motheo di teng kgethong ya thepa ya ho kwahela le thepa ya ho kwahela.
Metswako ya ho kwahela ka PVC le ya ho kwahela ka PVC e sebediswang ka hara dithapo tse tlwaelehileng e loketse haholo bakeng sa dibaka tsa ka tlung kapa tse bobebe, e fanang ka kganyetso e fokolang mochesong, ho pepesehela UV le botsofali. Ka lehlakoreng le leng, metswako ya ho kwahela ka polyolefin e hokahaneng le mahlaseli le ya ho kwahela ka dithapo tsa photovoltaic e ntshetswa pele ka ho kgetheha bakeng sa tshebetso ya kantle ya nako e telele mme e ka boloka tshebetso e tsitsitseng ya motlakase le ya mechini tlasa maemo a feteletseng a tikoloho.
Ka hona, le hoja ho nkela dikhoele tsa setso sebaka ka dikhoele tsa photovoltaic ho ka fokotsa ditjeo tsa pele, ho eketsa haholo dikotsi tsa tlhokomelo mme ho kgutsufatsa bophelo bohle ba tshebeletso ya sistimi ya photovoltaic.
6. Qetello: Khetho ea Thepa e Khetholla Tšepo ea Nako e Telele ea Mekhoa ea PV
Likhoele tsa photovoltaic ha se lintho tse bonolo tse ka nkeloang sebaka ke likhoele tse tloaelehileng, empa ke lihlahisoa tse khethehileng tsa cable tse etselitsoeng ka ho khetheha lits'ebetso tsa photovoltaic. Ho tšepahala ha tsona nako e telele ho itšetlehile haholo ka khetho ea thepa ea ho thibela likhoele tsa PV tse sebetsang hantle le thepa ea ho thiba, haholo-holo ts'ebeliso e nepahetseng ea litsamaiso tsa thepa ea polyolefin tse hokahaneng le mahlaseli.
Bakeng sa baqapi ba sistimi ea PV, ba kenyang, le bafani ba thepa ea cable, kutloisiso e felletseng ea liphapang tsa boemo ba thepa lipakeng tsa likhoele tsa photovoltaic le likhoele tse tloaelehileng ke ea bohlokoa ho netefatsa ts'ebetso e sireletsehileng, e tsitsitseng le ea nako e telele ea limela tsa motlakase tsa photovoltaic.
