Izindaba Zomkhiqizo

Idatha ye-HD11N Ukushintsha Ummese imele ingxenye ebalulekile ezinhlelweni zikagesi zesimanje ze-photovoltaic (PV), eziklanyelwe ngokuqondile ukusebenza okuphephile nokuthembekile ekusetshenzisweni kwamandla avuselelekayo. Njengedivayisi ezinikele yokunqamula, le swishi yommese iqinisekisa amandla okuzihlukanisa avikelekile kuyilapho ithobela izidingo eziqinile zokusebenza zokusatshalaliswa kwe-DC ne-AC ekufakweni kwamandla elanga. Ubunjiniyela bayo bugxile ekuqineni nasekuphepheni, okuyenza ifaneleke ukucushwa okuhlukahlukene kwe-PV yezimboni nezohwebo.

I-MCB I-Isolator Switch, ikakhulukazi uchungechunge lwe-BYG1-125, izakhi ezibalulekile zesistimu yokusabalalisa amandla yesimanje. Idizayinelwe ukunikeza ukuhlukaniswa kwesekethe okuphephile nokucacile, idivayisi ihlanganisa ukuvikelwa kwe-miniature circuit breaker (MCB) namandla ahlanzekile okunqanyulwa kwesihlukanisi. Njengephuzu lokulawula elibalulekile, likwazi ukunqamula ngokuphelele amandla kuma-circuits aphansi ngesikhathi sokulungiswa, ukulungiswa noma ukuvalwa kwezimo eziphuthumayo, ngaleyo ndlela kuqinisekiswe ukuphepha kwabasebenzi kanye nemishini. Ukwakhiwa kwayo okumazombezombe kanye nezindinganiso eziqinile zikagesi kuyenza ibe yinto ebaluleke kakhulu ezikhungweni zezentengiselwano nezimboni.

Uchungechunge lwe-BYW1 lumelele ukuqhubekela phambili okukhulu kubuchwepheshe bokuvikela ugesi. Idizayinelwe amagridi e-AC 50Hz, lesi sihlukanisi somoya esihlakaniphile emhlabeni wonke (ACB) silinganiselwe kufika ku-690V futhi sinamandla okubamba afika ku-6300A. Njengetshe legumbi lokusatshalaliswa kwamandla aphephile, ivikela ngokuthembekile ingqalasizinda ebalulekile ezimbonini zezimboni, izakhiwo zezentengiselwano, nezindawo ezinkulu ekufekeni kukagesi okuyinhlekelele.

Ukufakwa kukagesi kwesimanje kudinga izixazululo zokuphepha ezididiyelwe, futhi uchungechunge lwe-BY02L-63 luletha ukuvikeleka okubalulekile. Le Residual Current Circuit Breaker (RCBO) ihlanganisa i-overcurrent, short-circuit, kanye nokuvikela ukuvuza komhlaba ngaphakathi kwedivayisi eyodwa ehlangene. Ilinganiswe kumthamo wokuphuka okungu-3kA, ivikela amasistimu ezindawo zokuhlala, ezentengiselwano, nezimboni ezingozini zokushaqeka kukagesi kanye nezingozi zomlilo ezibangelwa amaphutha okushisa. Ngokuzwela kumaza asele ayingozi (ngokuvamile angu-30mA), inqamula ngokushesha amasekhethi lapho kwenzeka ukungalingani okusongela ukuphila, inikeze ukuvikelwa kwabasebenzi okubalulekile.

Uchungechunge lwe-BY08DC 1+2-12.5 lumelela intuthuko ebalulekile ekuvikelweni kwesistimu ye-photovoltaic. Le divayisi ekhethekile ye-Dc Surge Protective Device (SPD) iletha ukuvikelwa kokuhlinzwa kwe-T1+T2 okubalulekile okuklanyelwe amabhokisi okuhlanganisa ilanga nama-inverter. Isebenzisa ubuchwepheshe be-high-energy metal oxide varistor (MOV), inikeza ukuzivikela okuqinile ekushayweni kombani (10/350μs) kanye nokushintshashintsha kwezinto ezidlulayo (8/20μs). Ngamandla okukhipha asukela ku-20kA kuya ku-40kA isigxobo ngasinye, le SPD iqinisekisa ukuthi imishini ye-DC ebalulekile ihlala ivikelekile ekulimazeni okulimazayo kagesi kuwo wonke umjikelezo wayo wokuphila.

Uchungechunge lwe-BY04L-63 lumelela intuthuko ebalulekile ekuphepheni kukagesi, okuhlanganisa imisebenzi ebalulekile yokuvikela kudivayisi eyodwa. Le Residual Current Circuit Breaker (RCBO) inikeza ukuvikeleka okuphelele ngokumelene nezingozi ezintathu ezinkulu: i-overcurrent, i-short-circuit, kanye nama-residual currents ayingozi (ukuvuza komhlaba). Idizayinelwe ukwethembeka, ivikela ngempumelelo kokubili izisebenzi ekushayweni kukagesi nasekufakweni ezingozini zomlilo ezibangelwa amaphutha okufaka ugesi noma amandla amaningi, okuyenza ibe yisisekelo ezinhlelweni zikagesi zesimanje.
