UNGALUFAKA KANJANI UHLELO LAKHO LE-SOLAR PV

Uma uxhumaI-Slocableuhlelo lwe-solar pv, indlela ekahle kakhulu yokwengeza isiqiniseko ukusebenzisaMC4 amafuse or ama-solar circuit breakers.Ukusetshenziswa okufanele kwamafuse nama-circuit breaker kubalulekile ukugcina ukuphepha.Ama-Fuse nama-circuit breaker asetshenziselwa ukuvikela izintambo ekushiseni ngokweqile futhi futhi zivikele wonke amadivayisi axhunywe ohlelweni ekuqhumeni amalangabi noma ekulimaleni uma ukujikeleza okufushane kwenzeka.Isibonelo esihle ibhethri le-asidi eliholayo elingu-12V.Uma iDemo kwakheka kusiguquli se-AC/DC njengesibonelo, i-fuse phakathi kwayo nebhethri izovimbela ukuqhuma okungenzeka kwebhethri futhi izosika isekethe ngokushesha ngokwanele ukuvimbela izintambo ukuthi zingagqashuki amalangabi noma zishise ngendlela eyingozi.Kulesi simo, ibhethri, izintambo, nesiguquli se-AC/DC kuzovalwa ngokuvikelekile i-fuse.Azidingeki ukuze isistimu isebenze kahle, kodwa sihlala siphakamisa ukuthi kusetshenziswe amafuse noma ama-circuit breaker ngezinjongo zokuphepha.Kunezindawo ezintathu ezihlukene esiphakamisa ukuthi kufakwe ama-fuse noma ama-breaker: okokuqala, phakathi kwesilawuli sokushaja nebhange lebhethri, okwesibili, phakathi kwesilawuli sokushaja namaphaneli elanga, kanti okwesithathu kuzoba phakathi kwebhange lebhethri kanye ne-inverter.

Ukuze uthole usayizi we-fuse odingekayo phakathi kwesilawuli sokushaja nebhange lebhethri umane uqondanise isilinganiso se-amperage kusilawuli sokushaja.

I-fuse yesibili phakathi kwamaphaneli akho elanga nesilawuli sokushaja ihluke ngandlela thile ukuyiqonda.Usayizi wale fuse uncike ekutheni mangaki amaphaneli elanga onawo nokuthi axhumeke kanjani (uchungechunge, ukuhambisana, noma uchungechunge/ukuhambisana).Uma amaphaneli exhunywe ochungechungeni, i-voltage yephaneli ngayinye yengezwa kodwa i-amperage ihlala ifana.Isibonelo, uma unamaphaneli amane angu-100W axhunywe ochungechungeni, ngalinye likhiqiza ama-volts angu-20 nama-amps angu-5, inani eliphelele lingaba ama-volts angu-80 nama-amps angu-5.Sibe sesithatha isamba se-amperage bese siyiphindaphinda ngesici sokuphepha esingu-25% (5A x 1.25) esisinika isilinganiso se-fuse esingu-6.25A noma esingu-10A uma sihlanganisa.Uma unoxhumo oluhambisanayo, lapho i-amperage yamaphaneli yengezwa khona kodwa amandla kagesi ahlala engashintshile, kuzodingeka uhlanganise i-amperage yephaneli ngayinye bese sengeza umthetho womkhakha wama-25% ukuze uthole usayizi wefuse.Isibonelo, uma ubunamaphaneli amane angu-100W axhunywe kuxhumano olufanayo, iphaneli ngayinye ikhiqiza cishe ama-Amps angu-5, ngakho-ke sizosebenzisa lesi sibalo (4 * 5 * 1.25) = 28.75 Amps, ngakho-ke kulesi sibonelo singancoma ifuse engu-30 Amp. .

Amaphaneli elanga ezohwebo anamawathi angaphezu kuka-50 anezintambo eziyi-gauge ezingu-10 futhi angakwazi ukuphatha ama-currents afinyelela kuma-amps angu-30.Uma lawa maphaneli exhunywe ochungechungeni, okwamanje ngeke kwande, ngakho-ke intambo ayidingi ukuhlanganiswa.Uma uxhuma amaphaneli ngokuhambisana, akunjalo, ngoba uma uxhumeke ngokufana, imisinga yesistimu ihlanganisa.Isibonelo, uma unamaphaneli angu-4, ngalinye linganikeza kufika ku-15A wamanje, isifunda esifushane kuphaneli eyodwa izobangela wonke ama-60 A wamanje ukuthi ageleze kuphaneli ye-short-circuited.Lokhu kuzodala ukuthi izintambo eziholela kuphaneli zeqe kude ama-amps angama-30, okungase kubangele ukuthi izintambo ezimbili zibambe umlilo.Uma kuyiphaneli ehambisanayo, iphaneli ngayinye idinga ifuse engu-30 amp.Uma iphaneli yakho ingaphansi kwama-watts angu-50 futhi usebenzisa intambo ye-gauge engu-12 kuphela, udinga i-fuse engu-20 amp.

I-fuse yokugcina esiyiphakamisa ohlelweni kungaba uma usebenzisa i-inverter.Ukufaka izintambo nokuhlanganisa kusuka kubhethri kuya ku-inverter ye-AC/DC kubalulekile ngoba yilapho amandla aphezulu angageleza khona.Le fuse izoba phakathi kwe-inverter yakho nebhange lebhethri.Usayizi wefuse uvamise ukushiwo kumanuwali futhi ama-inverter amaningi kungenzeka abe nama-fuse/ama-circuit breaker akhelwe ngaphakathi ezinhlangothini ze-input and output (AC) zedivayisi.Umthetho wesithupha esiwusebenzisa lapha kungaba “Ama-Watts Aqhubekayo / Amandla Webhethri izikhathi ezingu-1.25, isibonelo isiguquli esivamile esingu-1000W 12V sidonsa cishe ama-amps angu-83 aqhubekayo futhi sizongeza isici sokuphepha esingu-25% esiphuma ku-105 Amps, ukuze ingaphakamisa i-fuse engu-150A.

Lesi isingeniso esifushane nesifinyezo sokuhlanganisa isistimu yakho.Kukhona ezinye izici ezibalulekile njengosayizi/ubude bekhebula kanye nezinhlobo ze-fuse/breaker.Ungakwazithumela i-imeyiliukuze uthole ulwazi olwengeziwe mayelana nemikhiqizo yelanga!Uma uthatha isikhathi sakho futhi usebenzisa inhlanganisela efanele yezingxenye ezilinganiselwe, isistimu kufanele isebenze kahle futhi uzolala kangcono wazi ukuthi uyiklame ukuze iphephe futhi ithembeke.
