Bitewe n’ikwirakwizwa rikomeye ry’amashanyarazi ya DC nka photovoltaic (PV) n’ibikoresho byo kubika ingufu, ingaruka z’umutekano ziterwa n’inkuba, guhindagurika kw’amashanyarazi, n’izindi ngorane z’amashanyarazi zikomeje kwiyongera ku isi. Ibicuruzwa byacuIgikoresho cyo kurinda cy’uruhererekane rwa RDU8DC (SPD), itanga ikoranabuhanga rihamye ryo kurinda DC n'imikorere yizewe cyane kugira ngo itange ibisubizo by'umwuga ku mutekano w'amashanyarazi arenze urugero ku nganda z'amashanyarazi za PV, uburyo bwo kubika ingufu n'ibindi.
Guhagarara k'amashanyarazi muri sisitemu z'amashanyarazi za DC bigira ingaruka ku buryo butaziguye ku gihe cy'ibikoresho no ku mikorere myiza y'amashanyarazi. Guhungabana kw'amashanyarazi guterwa no guhindagurika kw'amashanyarazi n'ihindagurika ry'urusobe rw'amashanyarazi ni bimwe mu bintu by'ingenzi bituma inverter ya PV yangirika ndetse n'uburyo bateri zibika ingufu zikoresha ubushyuhe. RDU8DC Series SPD yakozwe neza cyane ku bijyanye n'ibihe bya DC, ikemura ibibazo by'uburinzi ku rwego rwa tekiniki:
◆Byahinduwe neza na sisitemu za DC:Yagenewe byihariye porogaramu za DC zifite voltage nyinshi ya 1000VDC, ihuye neza n'ibisabwa kuri voltage ya module za PV na bateri zo kubika ingufu.
◆Ubushobozi bwo gucunga umuriro mwinshi:Ishobora kwihanganira inkuba zikomeye n'ihindagurika rikomeye ry'urusobe rw'amashanyarazi kugira ngo igabanye cyane igipimo cy'ibyangiritse ku bikoresho.
◆Umuvuduko muke w'ibisigaye mu rwego rwo kugenzura umutekano:Ikoresheje voltage isigaye (Hejuru) ≤ 4.0kV, ituma voltage yo ku ruhande rw'ibikoresho iguma mu buryo butekanye mu gihe cy'impanuka.
Kubera imikorere yayo mu kurinda umwuga,RDU8DC-B40 DC SPDByabaye ingenzi mu mutekano mu bihe byinshi bya DC:
●Imiterere y'inganda z'amashanyarazi zikoresha photovoltaic: Irinda udusanduku twa PV combiner na string inverters, ikagabanya ingaruka z'ubwiyongere bw'amashanyarazi ku mikorere myiza no kugabanya ikiguzi cy'imikorere.
●Imiterere ya sisitemu yo kubika ingufu:Itanga uburinzi bwa overvoltage ku byumba byo kubikamo bateri n'ibikoresho bya PCS, ikagabanya ibyago byo gutakaza ubushyuhe bwa bateri no kwemeza ko sisitemu ikora neza.
●Ibintu bya sitasiyo ya Telecom Base:Irinda DC rectifiers na bateri muri sitasiyo z'ibanze, ikomeza gukora neza kw'imiyoboro y'itumanaho mu gihe cy'ikirere kibi cyane.
