Ikhabethe (ibhokisi) elixhunywe kugridi ye-PV liyingxenye ebalulekile yokuvikela amandla kumasistimu okukhiqiza amandla axhumeke kuchungechunge lwe-photovoltaic, axhuma isiguquli esixhunywe ngochungechunge kanye nesistimu yegridi yamandla.Ingxenye yokuvikela isekethe yamukela i-PV grid-connected circuit breaker kanye ne-pull ring isolation switch, kanye nokuvikelwa kombani kwesibili.Iphinde ibe nezinyathelo eziningi zokuvikela, okuhlanganisa ukulayishwa ngokweqile, i-overcurrent, i-short circuit, ukuvuza, i-overvoltage, i-undervoltage, ukuqinisekisa ukusebenza okuphephile nokusebenza ngempumelelo kwesistimu.Idivayisi ingabuye ifakwe umsebenzi wokuxhumana ngokuvumelana nezidingo zamakhasimende, ukufeza ukuqapha okukude nokuphathwa kwezinhlelo zokukhiqiza amandla e-photovoltaic, ukuthuthukisa izinga lobuhlakani bomkhiqizo.Izinga lokuvikela lilingana ne-IP65, efanayo ne-inverter exhunywe kuchungechunge, ehlangabezana nezimfuneko zokufakwa ngaphandle, okuhlanganisa ukungangeni kwamanzi, ukuvikela uthuli, ukumelana ne-UV, kanye nokumelana nokugqwala ngokumelene nesifutho sikasawoti.Isakhiwo sangaphakathi somkhiqizo silula futhi sicacile, sinezintambo ezihlanzekile nezinengqondo, ukwethembeka okuphezulu, nokugcinwa okulula, okuvumelana nezimo ezihlukahlukene ezinokhahlo.
Ikhabhinethi yokusabalalisa ye-PV iyingxenye ebalulekile yokuthuthukiswa kwamanje kwemboni ye-solar photovoltaic.Umkhiqizo awugcini nje ngokuhlangabezana nezidingo zemakethe kodwa futhi ukhuthaza umphakathi ekuqondeni kohlaza, ikhabhoni ephansi kanye nentuthuko esimeme.Njengebhizinisi elisezingeni eliphezulu elinobuhlakani obusha, ikhwalithi yomkhiqizo nezinga lesevisi, sizoqhubeka nokuhlinzeka ngemikhiqizo namasevisi asezingeni eliphezulu kubasebenzisi bethu futhi senze umnikelo wethu ofanele ekuthuthukisweni kwemboni.
Khetha i-photovoltaic-specific grid-connected circuit breaker;
Khetha iswishi yokuhlukanisa i-photovoltaic yohlobo oluthile lwendandatho ukuze usebenze ngokuphephile.
Izinga lokuvikela le-IP65, lingangeni manzi, lingangeni kuthuli, futhi likwazi ukumelana ne-UV;
Ukuhlolwa okuqinile kokushisa okuphezulu nokuphansi, okulungele izifunda ezihlukahlukene;
Ukufakwa okulula, izintambo zesistimu ezenziwe lula, nezintambo ezilula;
Izindlu zakhiwe ngezinto zensimbi ezisezingeni eliphezulu njengamashidi ensimbi agoqelwe ngokubanda.
