Iindaba zeMveliso

Umfanekiso we-HD11N Knife Tshintsha imele icandelo elibalulekileyo kwiinkqubo zombane ze-photovoltaic (PV) zanamhlanje, ezenzelwe ngokukodwa ukusebenza okukhuselekileyo nokuthembekileyo kwizicelo zamandla avuselelekayo. Njengesixhobo esizinikeleyo sokuqhawula uqhagamshelo, olu tshintsho lwemela luqinisekisa ubunakho obukhuselekileyo bokwahlulwa ngelixa ubambelela kwiimfuno zokusebenza ezingqongqo ze-DC kunye nonikezelo lwe-AC kufakelo lwamandla elanga. Ubunjineli bayo bugxininise ekomeleleni nasekukhuselekeni, okwenza ukuba ilungele ukucwangciswa kwePV yamashishini kunye nezorhwebo.

MCB Ukutshintsha kwe-Isolator, ngakumbi uchungechunge lwe-BYG1-125, zizinto ezibalulekileyo kwiinkqubo zanamhlanje zokuhambisa amandla. Eyilwe ukubonelela ngokukhuselekileyo kunye nokucacileyo kweesekethe zodwa, isixhobo sidibanisa ukukhuselwa kwe-miniature circuit breaker (MCB) kunye nezakhono ezicocekileyo zokuqhawula i-isolator. Njengendawo yokulawula ebalulekileyo, iyakwazi ukunqumla ngokupheleleyo umbane kwiisekethe ezisezantsi ngexesha lokugcinwa, ukulungiswa okanye ukuvala ngokukhawuleza, ngaloo ndlela kuqinisekiswe ukhuseleko lwabasebenzi kunye nezixhobo. Ulwakhiwo lwayo olumagingxigingxi kunye nemigangatho engqongqo yombane iyenza ibe yinto ebaluleke kakhulu kwizibonelelo zorhwebo nezoshishino.

Uthotho lwe-BYW1 lumele ukutsibela phambili kwitekhnoloji yokhuseleko lombane. Yenzelwe iigridi ze-AC 50Hz, le ndawo ikrelekrele i-air circuit breaker (ACB) ilinganiswe ukuya kuthi ga kwi-690V kwaye inamandla okuphatha ngoku ukuya kwi-6300A. Njengelitye lembombo losasazo olukhuselekileyo lwamandla, ikhusela ngokuthembekileyo iziseko ezingundoqo kwizityalo zoshishino, iindawo zorhwebo, kunye nezixhobo ezinkulu ukusuka kwintlekele yokusilela kombane.

Ufakelo lombane lwangoku lufuna izisombululo ezidibeneyo zokhuseleko, kwaye uchungechunge lwe-BY02L-63 lunikezela ukhuseleko olubalulekileyo. Le Residual Current Circuit Breaker (RCBO) idibanisa i-overcurrent, i-short-circuit, kunye nokukhuselwa kokuvuza komhlaba ngaphakathi kwesixhobo esisodwa esidibeneyo. Inikwe umlinganiselo we-3kA yokophuka, ikhusela indawo yokuhlala, yorhwebo, kunye neenkqubo zoshishino kwiingozi zokothuka kombane kunye nemingcipheko yomlilo ebangelwa ziziphene zokugquma. Ngobuntununtunu kwimisinga yentsalela eyingozi (ngokuqhelekileyo i-30mA), iqhawula ngoko nangoko iisekethe xa kusenzeka ukungalingani okusongela ubomi, ibonelela ngokhuseleko lwabasebenzi olusisiseko.

Uluhlu lwe-BY08DC 1 + 2-12.5 lubonisa ukuqhubela phambili okubonakalayo ekukhuselweni kwenkqubo ye-photovoltaic. Esi sixhobo sikhethekileyo se-Dc Surge Protective Device (SPD) sinikezela ngokhuseleko oluyimfuneko lwe-T1 + T2 olulungiselelwe ngokukodwa iibhokisi ze-solar ezidibanisayo kunye nee-inverters. Ukusebenzisa iteknoloji ye-metal oxide varistor (MOV) ene-energy ephezulu, ibonelela ngokhuseleko oluluqilima ekubetheni kombane (10/350μs) kunye nokutshintsha okudlulayo (8/20μs). Ngokukhupha amandla asusela kwi-20kA ukuya kwi-40kA ngepali nganye, le SPD iqinisekisa ukuba izixhobo ze-DC ezibalulekileyo zihlala zikhuselwe ekonakalisweni kokunyuka kwamandla ombane kuwo wonke umjikelo wayo wokusebenza.

Uluhlu lwe-BY04L-63 lubonisa ukuqhubela phambili okubalulekileyo kukhuseleko lombane, ukudibanisa imisebenzi ebalulekileyo yokukhusela kwisixhobo esinye. Le Residual Current Circuit Breaker (RCBO) ibonelela ngokhuseleko olubanzi kwiingozi ezintathu ezinkulu: i-overcurrent, i-short-circuit, kunye nemisinga eseleyo eyingozi (ukuvuza komhlaba). Idizayinelwe ukuthembeka, ikhusela ngokufanelekileyo abasebenzi bobabini kumothuko wombane kunye nofakelo kwiingozi zomlilo ezibangwa ziziphene zokugquma okanye ukugqithiswa kwamandla ombane, oko kuyenza ibe sisiseko kwiinkqubo zombane zanamhlanje.
