Nekushandiswa kukuru kwemagetsi eDC pasi rose akadai se photovoltaic (PV) nenzvimbo dzekuchengetera simba, njodzi dzekuchengetedza dzinobva mukukwira kwemheni, ma voltage anochinja, uye mamwe matambudziko emagetsi ari kuramba achikwira. Chigadzirwa cheduRDU8DC Series Surge Protective Device (SPD), ichipa tekinoroji chaiyo yekudzivirira DC uye mashandiro akavimbika zvikuru ekupa mhinduro dzehunyanzvi dzekuchengetedza overvoltage kumaPV power plants, masisitimu ekuchengetera simba nezvimwewo.
Kugadzikana kwevoltage mumasisitimu emagetsi eDC kunokanganisa zvakanyanya hupenyu hwemichina uye kushanda zvakanaka kwemagetsi. Kuvhunduka kwemagetsi kunokonzerwa nekupinza kwemheni uye kushanduka kwegrid ndezvimwe zvezvinhu zvikuru zvinokonzera kukuvara kwePV inverter uye kuchengetedzwa kwesimba remabhatiri. RDU8DC Series SPD yakanyatsogadziriswa kuti ishandiswe zvakanaka mumamiriro ezvinhu eDC, ichigadzirisa marwadzo ekudzivirira padanho rehunyanzvi:
◆Yakanyatsogadziriswa kuti ienderane neDC Systems:Yakagadzirirwa zvakananga maapplication e1000VDC ane voltage yepamusoro, inonyatsoenderana nezvinodiwa zvevoltage zvePV modules uye mabheteri ekuchengetedza simba.
◆Kukwanisa Kubata Kwepamusoro Kwekukwira Kwemazuva Ano:Inogona kutsungirira kurohwa nemheni zvakanyanya uye kushanduka-shanduka kwegrid kuti ideredze zvakanyanya kukuvara kwemidziyo.
◆Voltage Yakaderera Yekuvimbisa Kuchengetedzeka:Nemagetsi akasara (Kukwira) ≤ 4.0kV, inoita kuti magetsi ari padivi pemidziyo arambe ari mukati memiganhu yakachengeteka panguva yekukwira kwemagetsi.
Nekuda kwekushanda kwayo kwehunyanzvi pakudzivirira,RDU8DC-B40 DC SPDrave chinhu chakakosha chekuchengetedza mune dzakawanda DC mamiriro:
●Mamiriro ePlant yemagetsi ePhotovoltaic: Inodzivirira mabhokisi ePV combiner nema string inverters, ichideredza kukanganiswa kwesimba remagetsi pakushanda zvakanaka kwemagetsi uye ichideredza mari yekushanda.
●Mamiriro eSisitimu Yekuchengetera Simba:Inopa dziviriro yemagetsi akawanda kumakabhini emabhatiri ekuchengetera simba uye maPCS converters, ichideredza njodzi yekurasa simba rebhatiri uye ichivimbisa kushanda kwakasimba kwesystem.
●Mamiriro eTelecom Base Station:Inodzivirira maDC rectifiers nemabhengi emabhatiri muzviteshi zvepasi, ichichengetedza kushanda kwenetwork yekutaurirana nguva dzose munguva yemamiriro ekunze akaipisisa.
