Ngenxa yokusasazwa okukhulu kweenkqubo zamandla zeDC ezifana ne-photovoltaic (PV) kunye neendawo zokugcina amandla kwihlabathi liphela, iingozi zokhuseleko ezivela kumbane ogqithisileyo, ukutshintshwa kwe-overvoltages, kunye nezinye iingxaki zombane ziyaqhubeka nokunyuka. Imveliso yethuIsixhobo soKhuseleko soKhuphiswano lwe-RDU8DC (i-SPD), inikezela ngetekhnoloji yokukhusela i-DC echanekileyo kunye nokusebenza okuthembekileyo kakhulu ukubonelela ngezisombululo zokhuseleko oluphezulu lwe-voltage kwiiplanti zamandla ze-PV, iinkqubo zokugcina amandla nokunye.
Uzinzo lwevolthi kwiinkqubo zamandla zeDC luchaphazela ngokuthe ngqo ubomi bezixhobo kunye nokusebenza kakuhle kokuveliswa kombane. Ukuqhambuka kombane okubangelwa kukufakelwa kombane kunye nokuguquguquka kwegridi ziphakathi kwezinto eziphambili ezibangela umonakalo kwi-PV inverter kunye nokubaleka kobushushu bebhetri yokugcina amandla. I-RDU8DC Series SPD ilungiselelwe kakhulu iimeko zeDC, ijongana neendawo zokukhusela iintlungu kwinqanaba lobuchwephesha:
◆Ilungelelaniswe ngokuchanekileyo kwiiNkqubo zeDC:Yenzelwe ngokukodwa usetyenziso lwe-DC olune-voltage ephezulu ye-1000VDC, ihambelana ngokugqibeleleyo neemfuno ze-voltage zeemodyuli ze-PV kunye neepakethi zebhetri yokugcina amandla.
◆Umthamo wokuphatha ngoku ophezulu wokunyuka kwangoku:Iyakwazi ukumelana nombane onzima kunye nokuguquguquka kwegridi okuntsonkothileyo ukunciphisa kakhulu amazinga omonakalo kwizixhobo.
◆I-Voltage eseleyo ephantsi yoQinisekiso loKhuseleko:Nge-voltage eseleyo (Phezulu) ≤ 4.0kV, iqinisekisa ukuba i-voltage esecaleni kwesixhobo ihlala ngaphakathi kwemida ekhuselekileyo ngexesha leziganeko zokusasazeka.
Ngenxa yokusebenza kwayo ngobuchule ekukhuseleni,I-RDU8DC-B40 DC SPDiye yaba yinto ephambili yokhuseleko kwiimeko ezininzi ze-DC:
●Imifanekiso yeZityalo zoMbane zePhotovoltaic: Ikhusela iibhokisi zokudibanisa ze-PV kunye nee-string inverters, inciphisa impembelelo yokunyuka kwamandla ekusebenzeni kakuhle kokuveliswa kombane kwaye inciphisa iindleko zokusebenza.
●Imeko zeNkqubo yokugcina amandla:Ibonelela ngokhuseleko olugqithisileyo kwiikhabhini zebhetri zokugcina amandla kunye nee-PCS converters, inciphisa umngcipheko wokubaleka kobushushu bebhetri kwaye iqinisekise ukusebenza okuzinzileyo kwenkqubo.
●Imeko zeSitishi seTelecom Base:Ikhusela ii-rectifiers ze-DC kunye neebhanki zebhetri kwizikhululo zesiseko, igcina ukusebenza kwenethiwekhi yonxibelelwano rhoqo ngexesha lemozulu embi.
