Ndi kufalikira kwakukulu kwa magetsi a DC padziko lonse lapansi monga photovoltaic (PV) ndi malo osungira mphamvu, zoopsa zachitetezo kuchokera ku mphezi, ma overvoltage osinthasintha, ndi zovuta zina zamagetsi zikupitirira kukwera.Chipangizo Choteteza cha RDU8DC Series Surge (SPD), kupereka ukadaulo wolondola woteteza DC komanso magwiridwe antchito odalirika kwambiri kuti apereke mayankho aukadaulo oteteza ku overvoltage pamakina opangira magetsi a PV, makina osungira mphamvu ndi zina zambiri.
Kukhazikika kwa magetsi m'makina amphamvu a DC kumakhudza mwachindunji moyo wa zida komanso momwe magetsi amagwirira ntchito. Kugwedezeka kwamphamvu komwe kumachitika chifukwa cha kulowetsedwa kwa mphezi ndi kusinthasintha kwa gridi ndi zina mwa zinthu zomwe zimayambitsa kuwonongeka kwa inverter ya PV komanso kutayika kwa kutentha kwa batri yosungira mphamvu. RDU8DC Series SPD yakonzedwa bwino kwambiri kuti igwirizane ndi zochitika za DC, pothana ndi ululu woteteza pamlingo waukadaulo:
◆Yosinthidwa Moyenera Kuti Igwirizane ndi Machitidwe a DC:Yopangidwira makamaka ntchito za 1000VDC high-voltage DC, imagwirizana bwino ndi zofunikira za ma voltage a ma PV modules ndi ma batri osungira mphamvu.
◆Kutha Kugwira Ntchito Kwambiri Pakali pano:Imatha kupirira kugunda kwamphamvu kwa mphezi ndi kusinthasintha kwa ma gridi kuti ichepetse kwambiri kuwonongeka kwa zida.
◆Voltage Yotsika Yotsalira Yotsimikizira Chitetezo:Ndi mphamvu yamagetsi yotsalira (Kukwera) ≤ 4.0kV, imatsimikizira kuti mphamvu yamagetsi ya mbali ya chipangizocho imakhalabe mkati mwa malire otetezeka panthawi yamavuto.
Chifukwa cha ntchito yake yoteteza mwaukadaulo,RDU8DC-B40 DC SPDchakhala chinthu chofunikira kwambiri pachitetezo m'magawo angapo a DC:
●Zochitika za Plant Power Plant: Imateteza mabokosi ophatikiza a PV ndi ma inverter a zingwe, kuchepetsa mphamvu ya kukwera kwa magetsi pakugwiritsa ntchito bwino magetsi ndikuchepetsa ndalama zogwirira ntchito.
●Zochitika za Machitidwe Osungira Mphamvu:Amapereka chitetezo champhamvu kwambiri m'mabatire osungira mphamvu ndi ma PCS converters, kuchepetsa chiopsezo cha kutentha kwa batire komanso kuonetsetsa kuti makinawo akugwira ntchito bwino.
●Zochitika za Siteshoni ya Telecom Base:Amateteza ma DC rectifiers ndi mabatire m'malo oyambira, kusunga ntchito yolumikizirana nthawi zonse panthawi yamvula.
