Ibhokisi lokuhlanganisa elixhunywe kwigridi ye-PV
Uhlolojikelele Lomkhiqizo
Ibhokisi lokuhlanganisa elixhunywe kugridi ye-photovoltaic lihlanganisa okokufaka kwe-DC kufika kwezingu-24 zezingxenye zamaseli e-photovoltaic ochungechungeni kube umphumela owodwa noma eminingi, okuphumayo ngakunye kufakwe amafuse, izibambisi zombani, nama-breaker circuit.Lokhu kwenza kube lula ukufaka izintambo zamakhabhinethi okusabalalisa e-DC nama-inverter, okuhlinzeka ngokuvikeleka embanini, kumasekhethi amafushane, nasekubekwe phansi.Ibhokisi lokuhlangana litholakala ngezinhlobo ezimbili: ezihlakaniphile nezingahlakaniphile.Ibhokisi lokuhlangana lokuvikela umbani elihlakaniphile lineyunithi yokuqapha yamanje ngaphakathi kwalo engaqapha okokufaka kwamanje kochungechunge lweseli ngalinye le-photovoltaic kanye nengqikithi yamandla kagesi okukhiphayo, kanye nezinga lokushisa elingaphakathi kwebhokisi, isimo sokubopha umbani, kanye nesimo. we-circuit breaker.
Isakhiwo sangaphakathi sedivayisi silula futhi sicacile, sinezintambo ezihlanzekile nezinengqondo.Idivayisi inokwethenjelwa okuphezulu futhi kulula ukuyinakekela.Ingafakwa ngaphandle odongeni, futhi ingakwazi ukuzivumelanisa nezimo ezihlukahlukene ezinokhahlo.Ngaphezu kwezingxenye ezibalulekile ezibalulekile, ezinye zingenziwa ngokwezifiso ngokuya ngezidingo zomsebenzisi.
Izici zomkhiqizo
★Ibanga lokuvikela lebhokisi lesihlanganisi lifinyelela ku-IP65, futhi lifakwe izinto ezingangeni manzi, zingangenwa uthuli, zingagqwali, nezifutho ngosawoti, zihlangabezana nezidingo zokufakwa ngaphandle:
★Ingakwazi ukuxhuma ngesikhathi esisodwa izintambo zebhethri ezingu-24:
★Isigxobo ngasinye esihle nesibi sochungechunge lwebhethri endleleni ngayinye ifakwe i-photovoltaic fuse ezinikele ukuvikela uchungechunge lwezingxenye kumaphutha.Isisekelo se-fuse kanye ne-fuse kubhanqiwe ukuze kusetshenziswe, kunciphisa izindleko zokunakekela umnikazi futhi kuvikela ngempumelelo ukuphepha komuntu siqu kwabasebenzi bokulungisa:
★Ngokusebenzisa i-photovoltaic ezinikele evikela amandla kagesi aphezulu, amatheminali alungile futhi angalungile ebha yebhasi ngemva kokuhlangana angavikelwa emhlabathini, futhi i-voltage eqhubekayo yokusebenza (Uc) ingafinyelela ku-1000VDC:
★Imojula yamandla ebhokisini lesihlanganisi ingaxhuma ku-voltage ephezulu ye-photovoltaic engu-1000DCV:
★Imojula yokulawula yebhokisi lesihlanganisi isebenzisa izinto ezithembekile ze-Honeywell Hall (izinzwa ze-DC CT) ukuze iqoqe idatha ku-voltage yamanje neyebhasi yentambo ngayinye ye-photovoltaic, iqaphe futhi ithole ama-alamu namaphutha endawo, futhi ikale izinga lokushisa ngaphakathi kwebhokisi lesihlanganisi, njengoba kanye nokubona isimo samadivayisi okuvikela umbani nama-breaker circuit okukhiphayo njll:
★Inekhono lokuxhumana le-serial RS485/MODBUS-RTU:
★Kunokuvikelwa kombani kuzo zonke izingxenye zesixhumi esibonakalayo zangaphandle:
★Ingathola ukulandwa kwepharamitha kumadivayisi okuqapha wendawo ukuze kuhlaziywe futhi kucutshungulwe:
★Ukunikezwa kwamandla okusebenzayo kwebhokisi lokuhlangana kungakhethwa ku-220VAC/DC yangaphandle noma ukunikezwa kwamandla okuhlinzekwa yibhokisi lokuhlangana ngokwalo.Uma ukunikezwa kwamandla okuhlinzekwa yibhokisi lokuhlangana ngokwalo kusetshenziswa, asikho isidingo sezintambo ezihlukene zokunikezwa kwamandla kusayithi:
