1. Teko ea Tensile ke Eng ka Lithapong tsa PV?
Teko ea tensile ke mokhoa o sebelisoang ho lekanya bokhoni ba thepa kapa karolo ea ho hanaho hula matlaho fihlela ho hloleha. Tabeng ea lithapo tsa photovoltaic, ke eona e etsang qeto ea hore na likarolo tsa mochine—tse kang insulation, sheath le conductor—li ka mamella hakae pele li robeha kapa li holofala.
Tekong ea matla, sampole ea thapo e tlanngoe lipheletsong ka bobeli ebe e huloa ka thoko ho sebelisoa amochini o hlahlobang bokahohleka lebelo le laoloang. Litekanyo li nkeloa:
-
Matla a ho roba(e lekantsoe ka Newtons kapa MPa),
-
Elongation nakong ya khefu(e otlolla bokae pele e hloleha), le
-
Matla a tšepe(khatello e phahameng eo thepa e ka e mamellang).
Liteko tsa tensile li etsoa kamekhahlelo ka bomongea thapo (insulation le sheath) le ka linako tse ling kopano e feletseng, ho itšetlehile ka litlhoko tse tloaelehileng.
2. Ke Hobane'ng ha U Etsa Teko ea Tensile ho Li-Cables tsa Photovoltaic?
Teko ea tensile ha se feela mokhoa oa laboratori - e amana ka kotloloho le ts'ebetso ea cable ea lefats'e ea nnete.
Mabaka a Bohlokoa Lithapo tsa PV li Hloka Teko ea Tensile:
-
Khatello ea ho kenya:Nakong ea likhoele, ho hula le ho kobeha, lithapo li pepesehela tsitsipano e ka bakang tšenyo e ka hare haeba matla a sa lekana.
-
Mathata a tikoloho:Khatello ea moea, moroalo oa lehloa, ho sisinyeha ha mechine (mohlala, ho tsoa ho li-trackers), kapa khoholeho ea lehlabathe e ka ba le matla ha nako e ntse e ea.
-
Tiisetso ea polokeho:Lithapo tse tlas'a tsitsipano tse petsohang, tse arohaneng, kapa tse lahleheloang ke conductivity li ka baka tahlehelo ea matla kapa esita le liphoso tsa arc.
-
Ho lumellana le ho tšepahala:Merero ea maemo a ts'ebeliso, khoebo le tikoloho e fetelletseng e hloka thepa ea mochini e netefalitsoeng ho fihlela maemo a lefats'e.
Ka bokhuts'oane, liteko tsa tensile li netefatsa hore thapo e khona ho mamellakhatello ea kelello ntle le ho hloleha, ho fokotsa likotsi le ho ntlafatsa botsitso ba nako e telele.
3. Maemo a Indasteri a Laolang Teko ea PV Cable Tensile
Lithapo tsa photovoltaic li tlameha ho lumellana le litekanyetso tse thata tsa machaba tse hlalosang litlhoko tse fokolang tsa ho tsitsisa likarolo tse fapaneng tsa thapo.
Maemo a Bohlokwa a kenyeletsa:
-
IEC 62930:E totobatsa matla a ho tiea le bolelele ba ho kenya letsoho le lisebelisoa tsa sheathing pele le ka mor'a ho tsofala.
-
EN 50618:Tekanyetso ea Europe bakeng sa likhoele tsa PV, e hlokang liteko bakeng sa ho tiea ha mochini, ho kenyelletsa le matla a thata a li-sheath le insulation.
-
TÜV 2PfG 1169/08.2007:E shebana le likhoele tsa lits'ebetso tsa PV tse nang le litekanyetso tsa motlakase ho fihla ho 1.8 kV DC, ho kenyeletsoa litlhoko tse qaqileng tsa liteko tsa tensile le elongation.
-
UL 4703 (bakeng sa mmaraka oa US):E boetse e kenyelletsa liteko tsa matla a tsitsipano nakong ea tlhahlobo ea lisebelisoa.
Tekanyetso ka 'ngoe e hlalosa:
-
Matla a fokolang a matla(mohlala, ≥12.5 MPa bakeng sa ho kenngoa ha XLPE),
-
Elongation nakong ya khefu(mohlala, ≥125% kapa ho feta ho latela thepa),
-
Maemo a teko ea botsofali(mohlala, botsofali ba ontong ka 120°C bakeng sa lihora tse 240), le
-
Mekhoa ea teko(bolelele ba mohlala, lebelo, maemo a tikoloho).
Litekanyetso tsena li netefatsa hore likhoele li tšoarella ka ho lekana ho fihlela litlhoko tsa lisebelisoa tsa letsatsi lefatšeng ka bophara.
4. Lisebelisuoa tsa Cable le Sebopeho li Amang Tšebetso ea Tensile joang
Ha se likhoele tsohle tsa PV tse entsoeng li lekana. Thesebopeho sa thepalemoralo oa cablephetha karolo e kgolo tabeng ya ho fumana matla a ho tsikitlanya.
Tšusumetso ea Lintho:
-
XLPE (Polyethylene e Khokahantsoeng):E fana ka matla a phahameng a tensile le botsitso ba mocheso, tse sebelisoang hangata ho likhoele tse lekantsoeng tsa EN 50618.
-
PVC:E theko e tlase, empa e na le matla a tlase a mochini — ha a ratehe haholo lits'ebetsong tsa PV tsa kantle kapa tsa maemo a holimo.
-
TPE / LSZH:Likhetho tse se nang mosi o tlase, tse se nang halogen tse leka-lekaneng ho feto-fetoha ha maemo le ts'ebetso e itekanetseng ea ho tsitsisa.
Tšusumetso ea Mokhanni:
-
Koporo e Tinngoeng:E eketsa ho hanyetsa kutu 'me e ntlafatsa tlamahano ea mochini le insulation.
-
Stranded vs. Solid:Li-conductors tse senyehileng li ntlafatsa ho tenyetseha le ho fokotsa kotsi ea ho robeha tlas'a tsitsipano e pheta-phetoang.
Moralo oa Sebopeho:
-
Matlafatso ea Sheath:Lithapo tse ling tsa PV li kenyelletsa likhoele tsa aramid kapa meralo ea sheath e habeli bakeng sa khanyetso e eketsehileng.
-
Multi-core vs. Single-core:Lithapo tsa li-multi-core hangata li na le boits'oaro bo rarahaneng ba mochini empa li ka rua molemo ho li-filler tse matlafalitsoeng.
Khetho ea thepa ea boleng bo holimo le moralo o ntlafalitsoeng oa sebopeho li matlafatsa bokhoni ba cable ho feta litekong tse thata le ho sebetsa tlasa maemo a masimong.
