Isixhobo Sokukhusela Ukunyuka (i-SPD): Ukhuseleko Olubalulekileyo Kwiinkqubo Zombane Zanamhlanje

Kwihlabathi lanamhlanje elinombane okhulayo nodibeneyo, iinkqubo zombane zihlala zijongene neengozi ezifanaumbane uyabetha, ukujikeleza okutshintshileyo, kunye nombane odlulayo odlulayoOku kunyuka kwamandla ombane ngequbuliso kunokubangela umonakalo omkhulu kwizixhobo zombane, kuphazamise ukusebenza, kwaye kukhokelele kwixesha elibi kakhulu lokungasebenzi. Kulapho keIzixhobo zoKhuselo lokuGqibela (i-SPD)badlale indima ebalulekileyo.

Yintoni i-SPD?

A Isixhobo sokukhusela ukugqabhuka (I-SPD)yenzelwe ukubakhusela iinkqubo zombane kunye nezixhobo kwi-overvoltages zexesha elifutshanengokujika amandla agqithisileyo okuphuma kwamanzi ajikeleze umhlaba ngokukhuselekileyo. Xa kuvela ukunyuka kwamanzi, i-SPD isabela ngoko nangoko, inciphise i-voltage ukuya kwinqanaba elikhuselekileyo kwaye ithintele umonakalo kwizixhobo ezixhunyiweyo.

Kutheni ii-SPD zibalulekile?

Ii-SPD zibalulekile ekuqinisekiseni ukuba:

• Ukukhuselwa kwezixhobo: Ukukhusela izixhobo zombane neze-elektroniki ezibuthathaka kwii-voltage spikes
• Ukuthembeka kwenkqubo: Ukunciphisa ixesha lokungasebenzi elibangelwa kukusilela okunxulumene nokunyuka okukhulu
• Uqinisekiso loKhuselekoUkuthintela iingozi ezinokubakho ezifana nokwaphuka kwe-insulation okanye iingozi zomlilo
• Ukusebenza kakuhle kweendleko: Ukunciphisa iindleko zokulungisa nezokutshintsha

Ngamaxesha okuphendula alinganiswa kwiii-nanoseconds, ii-SPD zisebenza njengomgca wokhuselo okhawulezayo nothembekileyo kwiinkqubo zombane.

Imizekelo yeSicelo esiQhelekileyo

Ii-SPD zisetyenziswa kakhulu kumashishini ahlukeneyo nakwiindawo ezingqongileyo, kuquka:

• Izakhiwo zoshishino kunye nezityalo zokuvelisa
• Izakhiwo zorhwebo kunye neeofisi
• Iinkqubo zombane zokuhlala
• Amaziko edatha kunye neenkqubo zonxibelelwano
• Iinkqubo zamandla avuselelekayo ezifana nokufakelwa kwamandla elanga (PV)
• Iinethiwekhi zokusasazwa kwamandla

ZombiniIinkqubo ze-AC kunye ne-DCzifuna ukhuseleko lokugaleleka, ingakumbi kwiindawo ezichatshazelwe ngumbane okanye imisebenzi yokutshintsha rhoqo.

Izisombululo ze-SPD zoMbane zeMutai

Njengomvelisi oqeqeshiweyo wezixhobo zombane ezisebenzisa umbane ophantsi,Iqela loMbane laseMutaiinikeza uluhlu olupheleleyo lweIzixhobo zoKhuseleko lokuGqibela kwe-AC kunye ne-DC, yenzelwe ukubonelela ngokhuseleko oluthembekileyo nolusebenzayo kwiintlobo ngeentlobo zezicelo.

Uthotho lwe-AC SPD

UMutai'sI-AC SPDiimveliso zifanelekileIinkqubo ze-220V/380V, enika ukhuseleko oluqinileyo kwimisinga yokuphuma kwamanzi ebangelwa ngumbane okanye ukuphazamiseka kwegridi.

Iimpawu eziphambili ziquka:

• Umsinga wokukhupha ophezulu (Imax)ixhomekeke ku100kA (8/20μs)
• Umsinga wokukhupha oqhelekileyo (ngaphakathi)ixhomekeke ku60kA (8/20μs)
• Inqanaba lokhuseleko eliphantsi (Phezulu)ukusuka1.5kV ukuya kwi-2.5kV
• Ixesha lokuphendula ngokukhawulezaengaphantsi kwe20ns
• Umsinga wokuvuza ophantsiukuphucula uzinzo lwenkqubo

Ezi SPD zilungele ukukhuselaiiphaneli zokusasaza, iikhabhinethi zombane, kunye neenkqubo zamandla ezakhiwo.

Uthotho lwe-DC SPD

UMutai'sI-DC SPDiimveliso zenzelwe ngokukodwaIinkqubo zeDC, ngakumbi kwiusetyenziso lwe-solar photovoltaic (PV)kunye nezinye iinkqubo zamandla avuselelekayo.

Iimpawu eziphambili ziquka:

• Umbane osebenzayo oqhubekayo ophezulu (Uc)ixhomekeke kuDC1500V
• Umsinga wokukhupha oqhelekileyo (ngaphakathi) of 20kA (8/20μs)
• Umsinga wokukhupha ophezulu (Imax) of 40kA (8/20μs)
• Inqanaba lokhuseleko (Phezulu)≤3.2kV
• Ixesha lokuphendula elikhawulezayo kakhulu of 25ns
• Iyahambelana neUfakelo lwesitimela se-DINukuze kube lula ukudibanisa

Ezi zixhobo zikhusela ngokufanelekileyoIinkqubo ze-PV, iinkqubo zokusasazwa kwe-DC, kunye nofakelo lokugcina amandlaukusuka ekunyukeni okwethutyana.

Ukhuseleko Oluthembekileyo Onokuluthemba

Ngoyilo oluphambili, izinto ezikumgangatho ophezulu, kunye nemigangatho yokuvelisa engqongqo, iimveliso ze-SPD zikaMutai Electric zibonelelaukusebenza okuzinzileyo, impendulo ekhawulezayo, kunye nokuthembeka kwexesha elideNokuba kukwiindawo zoshishino okanye kwiinkqubo zamandla avuselelekayo, ii-SPD zethu zinceda ekuqinisekiseni ukubaukusebenza okuqhubekayo kunye nokhuseleko lwezixhobo.
