Isikhokelo se-DC kunye ne-AC SPD Type 2 seeNkqubo zeLanga nezoMbane

Ndibone isiganeko esinye sokwanda kwemveliso sitshabalalisa iinyanga zemveliso, ngoko ke ndisoloko ndinyanga Isixhobo sokukhusela ukugquma njengento ephambili yoyilo, kungekhona into eyimfuneko.

Isikhokelo se-DC kunye ne-AC SPD Type 2 sichaza indlela Isixhobo sokukhusela ukugquma Izisombululo zikhusela iinkqubo zelanga nezombane kwi-overvoltage yexeshana, ziphucula ixesha lokusebenza, kwaye zinciphisa iindleko zokugcinwa kunye nokutshintshwa kwexesha elide.

Ukuba unomdla wokuhanjiswa okuqikelelweyo, umgangatho ozinzileyo, kunye nexabiso eliphantsi lobunini, ukuqonda ii-Type 2 SPDs yindawo ekrelekrele kakhulu onokuqala kuyo.

Yintoni isixhobo sokukhusela i-DC Surge

Ndihlala ndibona iingozi zeDC zinganakwa de izixhobo zingasebenzi, ngoko ke ndihlala ndiqala uphononongo lwenkqubo kwicala leDC.

A Isixhobo sokukhusela ukugquma kwe-DC ithintela umbane ogqithisileyo odlulayo kwiisekethe zeDC ngokujika amandla okuhamba ngokukhuselekileyo aye emhlabeni, ikhusela izixhobo ezixhunyiweyo ekonakalisweni.

Ndijonga ukhuseleko lwe-DC surge njengomaleko wokuqala wokuzikhusela kwiinkqubo zamandla elanga nakwimizi-mveliso. Iisekethe ze-DC zibonakala, zinde, kwaye zihlala zifakelwa ngaphandle. Oko kuzenza zibe sesichengeni kakhulu kwiintshukumo ezibangelwa ngumbane kunye neentshukumo ezitshintshayo. Isixhobo sokukhusela ukugquma Ifakwe kwicala le-DC isabela kwimizuzwana emincinci kwaye ibambe ii-voltage spikes eziyingozi ngaphambi kokuba zifikelele kwii-elektroniki ezibuthathaka.

Kwiifektri zokwenyani, ii-DC SPD zikhusela ii-inverters, izixhobo zombane ze-DC, iibhetri, kunye neesekethe zolawulo. Ngaphandle kwazo, ukunyuka okukodwa kunokubangela ukuphazamiseka kwe-insulation, ukungaphumeleli kwe-semiconductor, okanye ukuwohloka kokusebenza okusisigxina. Ndikubone oku kusenzeka kukhuseleko lwe-surge kwiifektri apho ixesha lokungasebenzi liguquka ngokukhawuleza libe lixesha lokugqibela lokuhanjiswa.

Uyilo oluhle lwe-DC SPD luhlala lujonga umgangatho womhlaba, ubude bentambo, kunye nendawo yokufakela. Andikaze ndiphathe ukhuseleko lwe-DC njengento ezimeleyo. Kufuneka lusebenze njengenxalenye yenkqubo yonke yomhlaba kunye nokubopha.

Uhlobo lwe-DC SPD 2 kwiinkqubo zelanga kunye namandla

Ndicebisa ii-Type 2 DC SPDs kwiindawo ezininzi zokusasazwa kwelanga kunye nombane.

Izixhobo ze-DC SPD Type 2 zenzelwe ukukhusela iinkqubo ze-DC kwimibane ebangelwa kukugqabhuka kunye nokutshintsha kwe-overvoltages kwiindawo zokufakelwa kwinqanaba lokusasazwa.

Kwiiprojekthi zam, ii-Type 2 DC SPDs zezona zisombululo zisetyenziswa kakhulu.

Ngokungafaniyo nezixhobo ze-Type 1, zilungiselelwe iibhodi zokusasaza, iibhokisi zokudibanisa, kunye nee-inverter inputs.

Ndikhetha ukhuseleko lwe-Type 2 kwi-solar yophahla, i-PV yorhwebo, kunye noninzi lwezicelo ze-SPD zemizi-mveliso. Zibonelela ngolungelelwano oluqinileyo phakathi kwenqanaba lokhuseleko kunye neendleko. Oku kubalulekile kubaphathi bokuthenga abafuna amaxabiso aqikelelweyo ngaphandle kokulahla ukuthembeka.

Ngokwamava, ii-Type 2 DC SPDs zinciphisa kakhulu iimpazamo ze-inverter eziphazamisayo kunye nokuvalwa okungachazwanga. Zikwandisa ubomi bezixhobo ngokunciphisa uxinzelelo lombane oluqokelelweyo. Oko kuthetha ngokuthe ngqo ukuba iindleko zokulungisa ziphantsi kunye nokuzinza okungcono kwenkqubo.

Ingcaciso yeeNqanaba zeVolthi zeDC SPD

Ndibona iimpazamo zokulinganisa i-voltage rhoqo kunayo nayiphi na enye impazamo yokukhetha i-SPD.

Uvavanyo lwe-voltage ye-DC SPD kufuneka ludlule kwi-voltage ephezulu yenkqubo ye-DC ukuze kuthintelwe ukungaphumeleli kwangaphambi kwexesha kunye nokulahleka kokhuseleko.

Andikhe ndikhethe i-SPD ngokusekelwe kwi-voltage eqhelekileyo yodwa. Ubushushu, iimeko zokusebenza, kunye nokwandiswa kwenkqubo zonke zichaphazela amanqanaba ombane okwenyani. Umzekelo, imozulu ebandayo inokutyhala i-voltage ye-PV evulekileyo ngaphaya kwamaxabiso e-nameplate.

Nantsi indlela endihlala ndiyifanisa ngayo imilinganiselo ye-voltage ye-DC:

Ukusebenzisa i-voltage rating efanelekileyo kuqinisekisa ukuba Isixhobo sokukhusela ukugquma isebenza ngokuthembekileyo ngokuhamba kwexesha endaweni yokusilela buthule emva kweziganeko ezimbalwa.

Uqwalaselo lwePole lwezixhobo zoKhuselo lweDC Surge

Ndisoloko ndiqinisekisa uqwalaselo lwepali ngaphambi kokuba ndivume nayiphi na i-DC SPD.

Uqwalaselo lwepali yesixhobo sokukhusela ukuvuza kwe-DC luchaza ukuba zingaphi ii-conductors ezikhuselekileyo kunye nendlela amandla okuvuza akhutshwa ngayo emhlabeni.

Uninzi lweenkqubo zelanga zisebenzisa ii-2P DC SPDs ukukhusela ii-conductors ezilungileyo nezingalunganga. Kwiinkqubo ezintsonkothileyo, iindlela ezahlukeneyo zokumisa umhlaba zinokufuna iipali ezongezelelweyo. Ukukhetha uqwalaselo olungalunganga kunokushiya inxalenye yenkqubo ingabonakali.

Kwiiprojekthi ze-SPD zoshishino, ndiqala ngokujonga kabini i-grounding topology kuqala. Oko kuthintela iingozi ezifihlakeleyo kwaye kuqinisekisa ukusebenza kokhuseleko rhoqo.

Yintoni isixhobo sokukhusela i-AC Surge

Ndiyithatha i-AC protection njengomaleko wesibini obalulekileyo wokhuseleko.

I-An Isixhobo sokukhusela ukugquma kwe-AC ithintela umbane ogqithisileyo odlulayo kwiintambo zombane ze-AC, ikhusela imithwalo kunye nezixhobo zokuhambisa ekonakaleni.

Ii-AC SPD zikhusela kwiintshukumo ezingena kwigridi okanye eziveliswa ngaphakathi ngokutshintsha izinto. Kwiinkqubo zelanga, zikhusela iziphumo ze-inverter, ii-switchboards, kunye nemithwalo esezantsi.

Ndisoloko ndidibanisa ii-AC kunye nee-DC SPDs kunye. Ukhuseleko oluzimeleyo alusebenzi kakuhle njengendlela yenkqubo edibeneyo.

I-AC SPD yeeNkqubo zeSigaba esinye kunye neSigaba esithathu

Ndilungisa ukhetho lwe-AC SPD ngokusekelwe kwi-topology yenkqubo.

Ii-AC SPD zikhethwa ngokwesimo sesigaba ukuqinisekisa ukhuseleko olulinganayo nolupheleleyo lokuntywila.

Iinkqubo zesigaba esinye zihlala zisebenzisa ulungelelwaniso olulula, ngelixa iinkqubo zesigaba sesithathu zifuna iindlela zokukhusela ezintsonkothileyo. Ndigxila kulungelelwaniso kunye nokusekwa komhlaba ukuze ndiphephe uxinzelelo olungalinganiyo ngexesha leziganeko zokusasazeka.

Le ndlela isebenza kakuhle kakhulu ekukhuseleni ukuxinana kwamanzi kwiifektri apho ulungelelwaniso lomthwalo kunye nokuqhubeka kwawo kubalulekile.

Uvavanyo lweVolji ye-AC SPD kunye noCwangciso

Ndisoloko ndifanisa ukulinganiswa kwe-AC voltage neemeko zokusebenza zokwenyani, kungekhona iilebhile kuphela.

Ukulinganiswa kwe-AC SPD voltage kunye noqwalaselo luchaza indlela ezithintelwa ngayo ngempumelelo ii-surges kwiinkqubo zokuhlala, zorhwebo, kunye nezoshishino.

Nantsi isalathiso esilula endisoloko ndisisebenzisa:

Uqwalaselo oluchanekileyo luqinisekisa ukuphambuka okuthembekileyo kokuvuza kwaye luthintela ukuguga kwe-SPD ngaphambi kwexesha.

Ukulungelelanisa i-AC kunye ne-DC SPD kwiiNkqubo zeSolar

Ndisoloko ndiyila ukhuseleko lokuhamba kwamanzi njengenkqubo edibeneyo.

Ukusebenzisa ii-AC kunye nee-DC SPDs kunye kudala ukhuseleko oluneeleya ezinciphisa i-residual voltage kwaye luphucula ukuthembeka kwenkqubo iyonke.

Ukulungelelanisa kuthetha ukubeka ii-DC SPDs kufutshane nee-PV arrays kunye nee-inverters, kunye nee-AC SPDs kwiindawo zokusasaza. Le ndlela enee-layered iqhelekile kuyilo lobuchwephesha lokuthintela ukusasazeka kwaye inika umngcipheko ophantsi wexesha elide.

Isiphelo

Khetha okulungileyo Isixhobo sokukhusela ukugquma icebo ngoku lokukhusela inkqubo yakho, ishedyuli yakho, kunye notyalo-mali lwakho lwexesha elide.
