Njengoba izinhlelo zikagesi ze-DC ezifana ne-photovoltaic (PV) kanye nezindawo zokugcina amandla emhlabeni wonke zisetshenziswa kabanzi emhlabeni jikelele, izingozi zokuphepha ezivela ekukhuphukeni kombani, ukushintshwa kwama-overvoltage, kanye nokunye ukuphazamiseka kukagesi kuyaqhubeka nokukhula. Umkhiqizo wethuIdivayisi Yokuvikela Ukwanda Kochungechunge lwe-RDU8DC (i-SPD), ihlinzeka ngobuchwepheshe bokuvikela obunembile be-DC kanye nokusebenza okuthembekile kakhulu ukuhlinzeka ngezixazululo zokuphepha kwe-overvoltage zobungcweti zezitshalo zamandla ze-PV, izinhlelo zokugcina amandla nokuningi.
Ukuqina kwe-voltage ezinhlelweni zamandla ze-DC kuthinta ngqo isikhathi sokuphila kwemishini kanye nokusebenza kahle kokukhiqizwa kwamandla. Ukushaqeka okukhulu okubangelwa ukufakelwa kombani kanye nokuguquguquka kwegridi kuphakathi kwezinto ezibangela umonakalo omkhulu we-PV inverter kanye nokubaleka kokushisa kwebhethri lokugcina amandla. I-RDU8DC Series SPD ilungiselelwe kakhulu izimo ze-DC, ibhekana nezindawo zobuhlungu zokuvikela ezingeni lobuchwepheshe:
◆Kulungiswe Ngokunembile Kuzinhlelo ze-DC:Yakhelwe ngqo izinhlelo zokusebenza ze-DC ezine-voltage ephezulu ye-1000VDC, ifanelana kahle nezidingo ze-voltage zamamojula e-PV kanye namaphakethe ebhethri lokugcina amandla.
◆Amandla Okuphatha Amanje Okukhuphuka Okuphezulu:Ingakwazi ukumelana nokushaywa kombani okukhulu kanye nokushintshashintsha kwegridi okuyinkimbinkimbi ukuze inciphise kakhulu amazinga okulimala kwemishini.
◆I-Voltage Ephansi Esele Yokuqinisekisa Ukuphepha:Nge-voltage eseleyo (Phezulu) ≤ 4.0kV, iqinisekisa ukuthi i-voltage eseceleni kwemishini ihlala ngaphakathi kwemingcele ephephile ngesikhathi semicimbi yokuqhuma.
Ngenxa yokusebenza kwayo kokuvikela kobungcweti,I-RDU8DC-B40 DC SPDsekuyinto ebalulekile yokuphepha kuzo zonke izimo eziningi ze-DC:
●Izimo Zesitshalo Samandla E-Photovoltaic: Ivikela amabhokisi okuhlanganisa e-PV kanye nama-inverter ezintambo, inciphisa umthelela wokwanda kwamandla ekusebenzeni kahle kokukhiqizwa kwamandla futhi yehlisa izindleko zokusebenza.
●Izimo Zesistimu Yokugcina Amandla:Ihlinzeka ngokuvikelwa kwe-overvoltage kuma-cabin ebhethri okugcina amandla kanye nama-converter e-PCS, inciphisa ingozi yokuphelelwa yisikhathi kokushisa kwebhethri futhi iqinisekise ukusebenza okuzinzile kohlelo.
●Izimo Zesiteshi Se-Telecom Base:Ivikela ama-rectifier e-DC namabhange ebhethri eziteshini eziyisisekelo, igcina ukusebenza kwenethiwekhi yokuxhumana okuqhubekayo ngesikhathi sezulu esibi kakhulu.
