01 Umgaqo Wokusebenza weeFusi Eziphumayo
Umgaqo oyintloko wokusebenza kwee-fuse eziphumayo kukusebenzisa i-overcurrent ukufudumeza nokunyibilikisa i-fuse element, ngaloo ndlela kwaphula i-circuit kwaye kukhusela izixhobo zombane ekonakalisweni.
Xa kwenzeka i-overload okanye i-short circuit kwi-circuit, i-fault current ibangela ukuba i-fuse ishushu ngokukhawuleza. Yakufika kwinqanaba lokunyibilika, iyanyibilika kwaye i-fuse tube iwele ngokuzenzekelayo, nto leyo evumela abasebenzi bokulungisa ukuba babone indawo ye-fault.
Olu yilo aluboneleli nje kuphela ngemisebenzi yokukhusela ethembekileyo, kodwa lukwayenza indawo apho kukho iziphene ibonakale kwangoko, nto leyo enciphisa kakhulu ixesha lokusombulula iingxaki nokugcinwa kwazo, kwaye iphucula ukuthembeka kwenkqubo yamandla.
02 Iimpawu zoBugcisa eziphambili
Iifusi zanamhlanje eziphumayo zineempawu ezininzi ezibalaseleyo. Zisebenzisa izixhobo zefusi eziqhuba umbane kakhulu, zisabela ngokukhawuleza, kwaye zinokunyibilika ngokukhawuleza xa kukho i-short circuit okanye i-overload.
I-fuse ephumayo ineempawu ezichanekileyo zokuphuka, ihambelana nemigangatho ye-IEC, kwaye iqinisekisa ukusebenza okuthembekileyo. Uyilo lwayo lwesakhiwo lwenza ityhubhu ye-fuse iwele ngokuzenzekelayo emva kokuphuka, nto leyo edala indawo ecacileyo yokuqhawula ukuze kuchongwe lula indawo yempazamo.
Le ndawo ivalekileyo yenziwe ngezinto zokukhusela eziqinileyo nezimelana nemozulu enamandla, ezifanelekileyo kwiindawo zangaphandle ezinzima. Kulula ukuyifaka, kwaye uyilo lwayo lobukhulu obuncinci luyasebenza kwiimeko ezahlukeneyo zokusasazwa kwamandla. Ibrakethi yokufaka ehamba nayo yenza lula inkqubo yokwakha kwaye inciphise iindleko zokulungisa.
03 Isicelo seTekhnoloji eNtsha
Kwiminyaka yakutshanje, itekhnoloji yeefusi eziphumayo iye yaphuculwa rhoqo. Ifusi ephumayo ye-mechanical interlock enelungelo lobunikazi yiHaosheng Electric Power iqinisekisa ukuba ityhubhu yefusi iyajikeleza kwaye iwe ngaphandle kokuwa emhlabeni ize yaphuke.
Ilungelo elilodwa lomenzi wefuse ephumayo efunyenwe yiHebao Electric linendlela entsha yokutsala, enciphisa ubunzima kubasebenzi xa besebenzisa intonga egqunyiweyo ukutsala ityhubhu yefuse, nto leyo ephucula ukulula nokusebenza kwayo.
"I-"intelligent drop-out fuse" eyaqaliswa yiZhejiang idibanisa ukugqithisa, i-short circuit, imisebenzi ye-alamu yobushushu obuphezulu kunye nokukwazi ukudlulisa idatha ngaphandle kweengcingo, ifezekisa ukwenziwa kwedijithali kwimeko yokusebenza kunye nokubonelela ngolwazi lokusebenza kwezixhobo ngexesha langempela kwi-smart grid.
04 Iziganeko eziqhelekileyo zokusetyenziswa
Iifusi eziphumayo zidlala indima ebalulekileyo kwiigridi zamandla zasemaphandleni, zisetyenziswa kwimigca yokusasaza ye-12kV ukukhusela izixhobo ezifana neetransformers kunye namasebe omgca.
Kwinethiwekhi zokusasazwa kwezixeko, zifanelekile kwiiyunithi eziphambili zeringi zangaphandle, iibhokisi zamasebe kunye nezinye iimeko, nto leyo ephucula ukuthembeka kokunikezelwa kombane. Kwicandelo lokusetyenziswa kombane kwimizi-mveliso, zibonelela ngokhuseleko lokugqithisela kunye nokhuseleko lwesekethe emfutshane kwimizi-mveliso, imigodi kunye nezinye iindawo.
Xa isetyenziswa kunye nesithinteli sombane, i-drop-out fuse inokwenza inkqubo yokuzikhusela enamaleko: ngexesha lokubetha kombane, isithinteli sombane sibamba i-overvoltage; ukuba umsinga wempazamo uyaqhubeka emva kokuba isithinteli sombane singasebenzi, i-fuse iya kuyihlukanisa inxalenye eyonakeleyo ukuthintela iimpazamo zokuwa.
05 Iingcebiso Zokukhetha Nokugcina
Xa ukhetha i-fuse ephumayo, khetha kuqala i-voltage efanelekileyo kunye ne-current ngokusekelwe kwiimfuno zokwenyani.
Kufuneka kuqwalaselwe isiqinisekiso semveliso ukuqinisekisa ukuba iimveliso ziyahambelana nemigangatho yesizwe kunye nemigangatho yoshishino, efana nomgangatho we-IEC 60282-1 10. Khetha ababoneleli abaneziqinisekiso zenkonzo elungileyo emva kokuthengisa ukuqinisekisa ukusetyenziswa ixesha elide ngaphandle kokukhathazeka 1.
Ngokuphathelele ukugcinwa, uyilo lwe-drop-out lunceda indawo yempazamo kwaye lunciphise ixesha lokucinywa kombane. Hlola rhoqo imeko ye-fuse, ingakumbi emva kwemozulu embi, ukuqinisekisa ukusebenza kwayo okuqhelekileyo. Kwii-fuse ezikrelekrele ze-drop-out, kubalulekile nokuba uqaphele ukuba umsebenzi wazo wokudlulisa idatha uqhelekile na.
