Iyini ikhebula le-Photovoltaic?

I-conductor cross-section: ikhebula le-photovoltaic

Isingeniso somkhiqizo: Ubuchwepheshe bamandla elanga buzoba obunye bobuchwepheshe bamandla aluhlaza obuzayo.I-Solar noma i-photovoltaic (PV) isetshenziswa kakhulu e-China.Ngaphezu kokuthuthukiswa okusheshayo kwezitshalo zamandla e-photovoltaic ezisekelwa uhulumeni, abatshalizimali abazimele nabo bakhuthele ekwakheni amafektri futhi bahlela ukufaka ekukhiqizeni amamojula eSolar athengiswa emhlabeni wonke.Kodwa okwamanje, amazwe amaningi asesesigabeni sokufunda.Akungabazeki ukuthi ukuze zithole inzuzo engcono kakhulu, izinkampani embonini kudingeka zifunde emazweni nasezinkampanini ezineminyaka eminingi yokuhlangenwe nakho kwezicelo zamandla elanga.

Ukwakhiwa kwezitshalo zamandla e-photovoltaic engabizi futhi enenzuzo kumelela umgomo obaluleke kakhulu kanye nokuncintisana okuyinhloko kwabo bonke abakhiqizi belanga.Eqinisweni, inzuzo ayixhomekile kuphela ekusebenzeni kahle noma ekusebenzeni okuphezulu kwemodyuli yelanga ngokwayo, kodwa futhi incike ochungechungeni lwezingxenye ezibonakala zingenabo ubuhlobo obuqondile nemodyuli.Kodwa zonke lezi zingxenye (njengeizintambo ze-photovoltaic, Izixhumi ze-PV, futhiAmabhokisi okuhlangana kwe-PV) kufanele zikhethwe ngokwezinjongo zokutshala izimali zesikhathi eside zomenzi wethenda.Izinga eliphezulu lezingxenye ezikhethiwe lingavimbela uhlelo lwelanga ukuba lube nenzuzo ngenxa yezindleko eziphezulu zokulungisa nokugcinwa.

Isibonelo, abantu ngokuvamile ababheki uhlelo lwezintambo oluxhuma amamojula we-photovoltaic nama-inverters njengengxenye eyinhloko.Kodwa-ke, uma ikhebula elikhethekile lezicelo zelanga lingasetshenziswa, impilo yesevisi yalo lonke uhlelo izothinteka.Eqinisweni, amasistimu elanga avame ukusetshenziswa ngaphansi kwezimo ezinzima zemvelo, njengamazinga okushisa aphezulu kanye nemisebe ye-ultraviolet.EYurophu, usuku olunelanga luzokwenza ukuthi izinga lokushisa elisendaweni yesimiso sonozungezilanga lifinyelele ku-100 ° C. Njengamanje, izinto ezihlukahlukene esingazisebenzisa yi-PVC, i-rubber, i-TPE kanye nezinto ezisezingeni eliphezulu zokuxhumanisa, kodwa ngeshwa, ikhebula lenjoloba elinezinga lokushisa elilinganiselwe lika-90 ° C, ngisho nekhebula le-PVC elinokushisa elilinganiselwe lika-70 ° C Libuye lisetshenziswe ngaphandle.Ngokusobala, lokhu kuzothinta kakhulu impilo yesevisi yesistimu.Ukukhiqizwa kwentambo yelanga ye-HUBER + SUHNER kunomlando weminyaka engaphezu kwengu-20.Imishini yelanga esebenzisa lolu hlobo lwekhebula eYurophu nayo isisetshenziswe iminyaka engaphezu kwengu-20 futhi isesesimweni esihle sokusebenza.

Ingcindezi yendawo ezungezile: Kuzinhlelo zokusebenza ze-photovoltaic, izinto ezisetshenziswa ngaphandle kufanele zisekelwe ku-UV, i-ozone, izinguquko ezinzima zokushisa, nokuhlaselwa kwamakhemikhali.Ukusetshenziswa kwezinto ezisezingeni eliphansi ngaphansi kokucindezeleka okunjalo kwemvelo kuzobangela ukuthi i-cable sheath ibe ntekenteke futhi ingase ibole ngisho nokufakwa kwekhebula.Zonke lezi zimo zizokwandisa ngokuqondile ukulahlekelwa kwesistimu yekhebula, futhi ingozi yokunciphisa ikhebula nayo izokhula.Esikhathini esimaphakathi nesikhathi eside, amathuba okuba nomlilo noma ukulimala komuntu siqu nawo aphezulu.

Intambo yelanga ye-HUBER + SUHNER RADOX® iyikhebula le-electron beam cross-link elinezinga lokushisa elilinganiselwe elingu-120 ° C, elingamelana nesimo sezulu esibi kanye nokushaqeka kwemishini emishinini yayo.Ngokwendinganiso yamazwe ngamazwe ye-IEC216, intambo yelanga ye-RADOX®, ezindaweni ezingaphandle, impilo yayo yesevisi iphindwe izikhathi ezingu-8 kunezintambo zenjoloba futhi izikhathi ezingu-32 kunezintambo ze-PVC.Lezi zintambo nezingxenye azigcini nje ngokukwazi ukumelana nesimo sezulu esingcono kakhulu, ukumelana ne-UV nokumelana ne-ozone, kodwa futhi zikwazi ukumelana noshintsho olubanzi lokushisa (isibonelo: kusuka ku--40 ° C kuya ku-125 ° C).

Ukuze kubhekwane nengozi engaba khona ebangelwa izinga lokushisa eliphezulu, abakhiqizi bavame ukusebenzisa izintambo ezifakwe kabili zenjoloba ezifakwe ngaphakathi (isibonelo H07 RNF).Kodwa-ke, inguqulo evamile yalolu hlobo lwekhebula ivunyelwe kuphela ukuthi isetshenziswe ezindaweni ezinokushisa okuphezulu kokusebenza okungu-60 ° C. EYurophu, izinga lokushisa elingalinganiswa ophahleni liphezulu njenge-100 ° C. izinga lokushisa elilinganiselwe lekhebula lelanga le-RADOX® lingu-120 ° C (lingasetshenziswa amahora angu-20,000).Lesi silinganiso silingana neminyaka engu-18 yokusetshenziswa ekushiseni okuqhubekayo kwe-90 ° C;lapho izinga lokushisa lingaphansi kuka-90 ° C, impilo yayo yesevisi iba yinde.Ngokuvamile, impilo yesevisi yemishini yelanga kufanele ibe ngaphezu kweminyaka engama-20 kuya kwengama-30.Ngokusekelwe kulezi zizathu ezingenhla, kudingekile kakhulu ukusebenzisa izintambo ezikhethekile zelanga kanye nezingxenye ohlelweni lwelanga.Ukumelana nomthwalo wemishini Eqinisweni, ngesikhathi sokufakwa nokugcinwa, ikhebula lingahanjiswa onqenqemeni olubukhali lwesakhiwo sophahla, futhi ikhebula kufanele limelane nokucindezela, ukugoba, ukungezwani, umthwalo we-cross-tensile nomthelela onamandla.Uma amandla ejazi lekhebula enganele, ukuhlukaniswa kwekhebula kuzolimala kakhulu, okuzothinta impilo yesevisi yekhebula lonke, noma kubangele izinkinga ezifana neziyingi ezimfushane, umlilo, nokulimala komuntu siqu.I-cross-linked material enemisebe inamandla amakhulu okusebenza.Inqubo yokuxhumanisa ishintsha ukwakheka kwamakhemikhali e-polymer, futhi izinto ze-thermoplastic ze-fusible ziguqulwa zibe izinto ze-elastomer ezingenafusible.Imisebe ye-Cross-link ithuthukisa kakhulu izakhiwo ezishisayo, zemishini kanye nezamakhemikhali zezinto zokufakwa kwamakhebula.Njengemakethe yelanga elikhulu kunawo wonke emhlabeni, iJalimane ihlangabezane nazo zonke izinkinga ezihlobene nokukhetha ikhebula.Namuhla eJalimane, ngaphezu kuka-50% wezinto zokusebenza zisebenzisa izintambo ze-HUBER + SUHNER RADOX® ezinikelwe ezinhlelweni zelanga.
