Isixhobo soKhuseleko lweSolar Surge Slocable

Uthini umgaqo wesixhobo sokukhusela ukunyuka kwelanga kunye nendlela yokukhetha umkhuseli ofanelekileyo welanga?

       Isixhobo sokukhusela iSolarluhlobo lwesixhobo sombane esibonelela ngokhuseleko lwezixhobo ezahlukeneyo zombane kunye neentambo zonxibelelwano.Xa i-peak yangoku okanye i-voltage yenziwa ngequbuliso kwisekethe yombane okanye isekethe yonxibelelwano ngenxa yokuphazamiseka kwangaphandle, ukukhuselwa kwe-pv surge kunokuqhuba kwaye kuthintele ngexesha elifutshane kakhulu, ukunqanda umonakalo wokutyanda kwezinye izixhobo kwisekethe. .Eli nqaku ligxininisa ukuba yintoni umgaqo womkhuseli welanga kunye nendlela yokukhetha umkhuseli ofanelekileyo wokutya.

Uthini umgaqo wesixhobo sokukhusela i-solar surge?

Izixhobo zokukhusela iSolar zikwabizwa ngokuba zizixhobo zokukhusela umbane.Ngokwemigangatho ye-IEC kazwelonke, zisetyenziswa ikakhulu ukunciphisa umbane ogqithisayo kunye nokuqukuqela okudlulayo kumgca.Umkhuseli wokunyuka kwelanga unempembelelo ekhuselekileyo yokukhusela kwizixhobo zombane, ithwala umbane olindelekileyo ngoku.Emva koxinzelelo oluphezulu lomkhuseli we-pv, ithatha ngokufanelekileyo i-frequency yamandla eqhubekayo eyenziwayo emva kokudlula kombane, kwaye iya kudlula kumgca wamandla kunye nomgca wokuhambisa umqondiso.I-overvoltage ekhawulezileyo okanye i-overcurrent icinezelwe ngaphakathi kombane onokuthi isixhobo kunye nomkhuseli bakwazi ukumelana, okanye umbane omkhulu ungeniswa emhlabeni ukukhusela izixhobo.

Isixhobo esiqhelekileyo sokukhusela ukushukuma kwelanga sihambisa umsinga ukusuka kwisokethi yamandla ukuya kwizixhobo ezininzi zombane neze-elektroniki eziplagiswe kwibhodi yamandla.Ukuba i-surge or spike ibangela ukuba i-voltage idlule kwinqanaba elamkelekileyo, i-SPD yelanga iya kudlulisela umbane ogqithiseleyo kumhlaba wokuphuma kwamandla.

Kwezona zixhobo ziqhelekileyo zokukhusela i-solar surge, kukho icandelo elibizwa ngokuba yi-metal oxide varistor, esetyenziselwa ukuhambisa i-voltage engaphezulu.I-MOV yenziwe ngamacandelo amathathu: Embindini kukho i-metal oxide material, kunye ne-semiconductors ezimbini zixhunyiwe kumbane kunye nomhlaba.

Ezi semiconductors zinokuchasana okuguquguqukayo okutshintsha kunye notshintsho kumbane.Xa i-voltage iphantsi kunexabiso elithile, ukuhamba kwee-electron kwi-semiconductor kuya kuvelisa ukuxhathisa okuphezulu kakhulu.Ngokuchasene noko, xa i-voltage idlula eli xabiso elithile, ukuhamba kwee-electron kuya kutshintsha kwaye ukuchasana kwe-semiconductor kuya kuncitshiswa kakhulu.

Unokukhetha njani isixhobo esifanelekileyo sokukhusela ilanga?

Xa uthenga isixhobo sokukhusela i-solar surge, ngokuqhelekileyo kufuneka ulumke kakhulu.Esona sizathu sesokuba imarike yangoku izaliswe ziimveliso ezingenazo naziphi na iziphumo.Eyona ndlela ingcono yokuthenga imveliso efanelekileyo kukuphanda imodeli ethile.Ngokuqinisekileyo, kufuneka uhlawule ngononophelo kumanqaku amaninzi asemgangathweni, kwaye kwangaxeshanye kufuneka uqonde ngcono umgangatho wokusebenza kwemveliso.

Xa ukhetha, kufuneka ukhangele ixabiso elihambelanayo.Phantsi kweemeko eziqhelekileyo, musa ukuba nezinto ezilindelekileyo kakhulu kwi-DC SPD enexabiso eliphantsi.Esona sizathu sikukuba ezi zixhobo zihlala zisebenzisa ii-MOV ezilula nezingabizi kakhulu, ngoko ke amandla azo anqongophele.Ngexesha lokusetyenziswa kwemihla ngemihla, emva kokuba i-spike enkulu okanye i-spike yenzeke, inkqubo yomsebenzisi ayiyi kukwazi ukukhusela inkqubo yomsebenzisi.

Ewe kunjalo, ixabiso eliphezulu le-dc surge protector solar ayithethi umgangatho olungileyo.Kubathengi abafuna ukukhetha oyena mkhuseli ofanelekileyo, kufuneka bajonge iimpawu ezihambelanayo.Oku kubaluleke kakhulu.

Eli nqaku ligxile kumgaqo-siseko wesixhobo sokukhusela i-solar surge kunye nendlela yokukhetha umkhuseli ofanelekileyo welanga.Ngezi zixhobo, wonke umntu kufuneka akwazi ukuqonda umgaqo we-solar DC SPD.Indima yabakhuseli botyando ibonakala, kodwa wonke umntu kufuneka anikele ingqalelo ekukhetheni ukuthenga ngomgangatho olungileyo.
