Lehoatata, le nang le khanya ea letsatsi le khanyang selemo ho pota le sebaka se seholo se bulehileng, se nkoa e le se seng sa libaka tse ntle ka ho fetisisa bakeng sa ho tsetela mererong ea ho boloka matla a letsatsi le matla. Mahlaseli a letsatsi a selemo le selemo libakeng tse ngata tsa lehoatata a ka feta 2000W/m², e leng se etsang hore e be morafo oa khauta bakeng sa ho hlahisa matla a ka nchafatsoang. Leha ho le joalo, melemo ena e tla le mathata a bohlokoa a tikoloho - ho fetoha ha mocheso o feteletseng, sefefo se matla sa lehlabathe, ho pepesehela mahlaseli a kotsi a mahlaseli a kotsi le mongobo ka linako tse ling.
Lithapo tsa photovoltaic tsa lehoatata li entsoe ka mokhoa o khethehileng ho mamella maemo ana a thata. Ho fapana le likhoele tse tloaelehileng tsa PV, li na le lisebelisoa tse ntlafalitsoeng le lisebelisoa tsa sheath ho netefatsa ts'ebetso e bolokehileng le e tsitsitseng libakeng tse hole le tse matsutla tsa lehoatata.
I. Mathata a Lithapo tsa PV Mafelong a Lehoatata
1. Mahlaseli a phahameng a UV
Mahoatata a fumana khanya ea letsatsi e sa khaotseng, e otlolohileng e nang le maru a fokolang kapa moriti. Ho fapana le libaka tse futhumetseng, mahlaseli a kotsi a UV mahoatateng a lula a phahame selemo ho pota. Ho pepeseha ha nako e telele ho ka etsa hore sheath ea cable e senyehe, e be brittle, kapa e petsohe, e leng se lebisang ho hloleheng ha insulation le likotsi tse kang li-circuits tse khutšoane kapa esita le mollo.
2. Phetoho e Feteletseng ea Mocheso
Lehoatata le ka ba le ho fetoha ha mocheso oa 40°C kapa ho feta ka letsatsi le le leng - ho tloha ho mocheso oa +50 ° C litlhōrōng tsa motšehare ho ea ho mocheso o batang bosiu. Litšisinyeho tsena tsa mocheso li etsa hore lisebelisoa tsa cable li atolosoe khafetsa le konteraka, li beha khatello ho insulation le sheath. Hangata lithapo tse tloaelehileng li hlōleha tlas'a khatello e joalo ea cyclical.
3. Mocheso o Kopantsoeng, Mongobo, le Abrasion
Lithapo tsa lehoatateng ha li tobane le mocheso le ho omella feela empa li boetse li talimana le meea e matla, likaroloana tsa lehlabathe le hlabang, le pula e nang ka linako tse ling kapa mongobo o mongata. Khoholeho ea lehlabathe e ka senya thepa ea polymer, e lebisang ho petsoha kapa ho phunya. Ho feta moo, lehlabathe le letle le ka kenella lihokelong kapa mabokoseng a li-terminal, la eketsa ho hanyetsa motlakase le ho baka kutu.
II. Moralo o Khethehileng oa Lithapo tsa Lehoatata tsa PV
1. Kaho e Hanyetsang UV
Lithapo tsa lehoatata tsa PV li sebelisa XLPO e tsoetseng pele (polyolefin e amanang le sefapano) bakeng sa sheath le XLPE (polyethylene e kopantsoeng le sefapano) bakeng sa ho kenya letsoho. Lisebelisoa tsena li lekoa tlas'a maemo a machaba a kangEN 50618leIEC 62930, tse akarelletsang botsofali ba letsatsi le etsisoang. Phello: nako e telele ea bophelo ba cable le ho fokotsa ho senyeha ha thepa tlas'a letsatsi le sa khaotseng la lehoatata.
2. Mamello e Bophara ea Mocheso
Ho fihlela litlhoko tsa phetoho ea maemo a leholimo a lehoatata, likhoele tsena li sebetsa ka ts'epo maemong a fapaneng a mocheso:
-40°C ho ea +90°C (e tsoelang pele)le ho fihlela+120°C (boima ba nako e khutšoane). Ho feto-fetoha ha maemo ho thibela mokhathala oa mocheso le ho netefatsa phetisetso e tsitsitseng ea matla esita le ka liphetoho tse potlakileng tsa mocheso.
3. Matla a Matla a Mechini
Li-conductors ke mehala ea koporo kapa ea aluminium e holehiloeng hantle, e kopantsoeng le likhetla tsa XLPO tse ntlafalitsoeng ka mochini. Lithapo tsena li khona ho etsa liteko tse matla le ho lelefatsa ha lehlabathe, tse li thusang hore li khone ho mamella ho khongoa ke lehlabathe, ho hahloa ke moea le khatello ea ho e kenya libakeng tse telele.
4. Tiiso e Phahameng ka ho Fetisisa e sa Keneng Metsing le e Thibelang Lerōle
Le hoja mahoatata a atisa ho omella, ho phahama ha mongobo, lipula tsa tšohanyetso, kapa ho hoama ho ka senya botšepehi ba tsamaiso. Lithapo tsa lehoatata tsa PV li sebelisa lisebelisoa tse phahameng tsa XLPE tse sa keneleng metsi hammoho leLihokelo tse lekantsoeng ka IP68, lumellana leAD8 litekanyetso tsa ho thibela metsi. Sena se tiisa tšireletso e nepahetseng libakeng tse lerōle kapa tse mongobo, ho fokotsa nako le ho lelefatsa nako ea lisebelisoa - haholo-holo libakeng tse hole, tseo ho leng thata ho li hlokomela.
III. Mehopolo ea ho Kena bakeng sa Lithapo tsa Lehoatata tsa PV
Mapolasing a maholo a letsatsi, likhoele tse behiloeng ka kotloloho mobung oa lehoatata li tobana le likotsi tse kang:
-
Ho pepeseha ha mocheso o phahameng
-
Lehlabathe le hlabang
-
Ho bokellana ha mongobo
-
Tšenyo ea litoeba kapa lisebelisoa tsa tlhokomelo
Ho fokotsa tsena, ho kgothaletswa hophahamisa mehala ho tloha fatsheho sebelisa lisebelisoa tsa cable tse hlophisitsoeng. Leha ho le joalo, meea e matla ea lehoatata e ka etsa hore lithapo tse sa sirelelitsoeng li thekesele, li thothomele kapa li tsube libakeng tse nchocho. Ka hona,Li-clamps tsa tšepe tse sa hloekang tse hanyetsanang le UVli bohlokoa ho tiisa likhoele ka mokhoa o sireletsehileng le ho thibela ho senyeha.
Qetello
Lithapo tsa lehoatata tsa photovoltaic ha li felle feela lithapo - ke mokokotlo oa phetisetso ea matla e tsitsitseng, e sebetsang hantle haholo maemong a mang a leholimo a thata ka ho fetesisa a Lefatše. Ka ts'ireletso ea UV e matlafalitsoeng, mamello e pharalletseng ea mocheso, ho thibela metsi ho feta, le ho tšoarella ha mochini, likhoele tsena li entsoe ka sepheo sa ho tsamaisoa ha nako e telele lits'ebetsong tsa letsatsi lehoatateng.
Haeba u rera ho kenya letsatsi libakeng tsa lehoatata,ho khetha thapo e nepahetseng ho bohlokoa bakeng sa polokeho ea sistimi ea hau, ts'ebetso le bophelo bo bolelele.
