I-National Electrical Manufacturers Association (NEMA) ngumbutho owaziwa ngegalelo lawo ekulinganiseni ukuveliswa kunye nokusetyenziswa kwezixhobo zombane.Omnye weyona misebenzi inefuthe kakhulu ye-NEMA luhlelo lweNEMA oluvalekileyo, iseti ebanzi yemigangatho ehlela iindawo ezivaliweyo ngokusekelwe kumandla azo okumelana neemeko ezahlukeneyo zokusingqongileyo.Olunye ulinganiso olunjalo ngumgangatho we-NEMA 4, esiza kuphonononga kuwo kweli nqaku.
Ukuchaza iNEMA 4 ebiyelweyo
Indawo ebiyelweyo ye-NEMA 4 yindlu eyomeleleyo nengenwa yimozulu yezixhobo zombane eyenzelwe ukukhusela kwizinto eziyingozi ezifana nothuli, imvula, ikhephu, ikhephu, kunye namanzi ajongwe ngombhobho.Ezi zivalo zenzelwe ikakhulu ukusetyenziswa ngaphakathi okanye ngaphandle, zibonelela ngokhuseleko olumandla kwiinkqubo zombane kwiindawo ezahlukeneyo ezinzima.
Izinto eziluncedo zokuSebenzisa i-NEMA 4 ebiyelweyo
Inzuzo ephambili ye-NEMA 4 evaliweyo yinqanaba labo eliphezulu lokukhusela kuluhlu lwezinto ezisingqongileyo.Ezi zivalo ezomeleleyo ziluthuli kwaye zingenamanzi, zikhusela amacandelo ombane ekonakalisweni ngenxa yezinto zangaphandle okanye ukungena kwamanzi.Ukongeza, iindawo ezivaliweyo ze-NEMA 4 zinokumelana nokwakheka komkhenkce wangaphandle kwaye zomelele ngokwaneleyo ukuxhathisa iimpembelelo zomzimba, zibonelela ngoxolo lwengqondo kubasebenzi kwiimeko ezinzima.
Usetyenziso oluQhelekileyo lwe-NEMA 4 ebiyelweyo
Iindawo ezivaliweyo ze-NEMA 4 zisetyenziswa kakhulu kwimizi-mveliso eyahlukeneyo, urhwebo, kunye nesetingi zangaphandle.Ezi ndawo zivaliweyo zifanelekile kwiindawo eziphantsi kweemeko zemozulu ezimandundu okanye iindawo apho izixhobo kufuneka zihlanjululwe rhoqo, njengemizi-mveliso yokutya neyeziselo.Ukongezelela, zixhaphake kwiindawo zokuvelisa, iinkqubo zokulawula izithuthi, iindawo zokwakha, kunye nezinye izicelo zangaphandle apho ukhuseleko kwiingozi zokusingqongileyo kubalulekile.
Ukuthelekisa iindawo ezibiyelweyo ze-NEMA 4 kunye nolunye uqikelelo lwe-NEMA
Ngelixa izivalo ze-NEMA 4 zibonelela ngokhuseleko olugqwesileyo, kubalulekile ukuqonda ukuba zithelekiseka njani nezinye iireyithingi ze-NEMA.Umzekelo, ngelixa indawo ebiyelweyo ye-NEMA 3 ibonelela ngokhuseleko emvuleni, kwisikhindi nakwikhephu, ayikuqinisekisi ukhuseleko kumanzi ajongwe ngumbhobho, uphawu oluhambelana ne-NEMA 4. Nangona kunjalo, ukuba ufuna indawo ebiyelweyo ekhusela kwizinto ezidlayo, ungaqwalasela indawo ebiyelweyo ye-NEMA 4X, ebonelela ngayo yonke into eyenziwa yi-NEMA 4, kunye nokuxhathisa umhlwa.
Ukukhetha iNEMA 4 Eyeyona ibiyelweyo yeProjekthi yakho
Indawo evaliweyo ye-NEMA 4 ixhomekeke kwiimfuno ezithile zeprojekthi yakho.Imiba ekufuneka iqwalaselwe ibandakanya ubume bemeko engqongileyo (ngaphakathi okanye ngaphandle), ukuba sesichengeni kwiingozi ezinokubakho (uthuli, amanzi, impembelelo), kunye nobukhulu kunye nodidi lwezixhobo zombane eziza kugcinwa.Ukukhetha izinto eziphathekayo nako kudlala indima ebalulekileyo, kunye nokhetho olufana nentsimbi yekhabhoni, intsimbi engatyiwa, kunye nepolycarbonate, nganye ibonelela ngeenzuzo ezahlukeneyo.
I-Case Study: Ukusetyenziswa ngokuyimpumelelo kweNEMA 4 Ebiyelweyo
Cinga ngeprojekthi yokwakha yangaphandle echanabeke kwiimvula ezinkulu nothuli.Iinkqubo zokulawula umbane zeprojekthi zazifuna ukukhuselwa kwezi zinto.Isisombululo sasiyindawo evaliweyo ye-NEMA 4, eyakhusela ngempumelelo amacandelo ombane, ukuthintela ukwehla kokusebenza kunye nomonakalo wezixhobo.
Imibuzo Ebuzwa Rhoqo malunga neNEMA 4 ebiyelweyo
Eli candelo lingabandakanya imibuzo eqhelekileyo malunga neendawo ezivaliweyo ze-NEMA 4, ezifana nokwakhiwa kwazo, ukugcinwa kwazo, ukufaneleka kweendawo ezahlukeneyo, nokunye.
Isiphelo: Kutheni i-NEMA 4 Enclosure iluKhetho Olugqwesileyo lweeNdawo eziQolileyo
Iindawo ezivaliweyo ze-NEMA 4 zibonelela ngenqanaba eliphezulu lokhuseleko lwamalungu ombane kwiindawo ezinomngeni.Ukukwazi kwabo ukuxhathisa uthuli, amanzi, kunye neempembelelo zomzimba kubenza babe lolona khetho lubalaseleyo kwiinkqubo ezininzi zangaphakathi nangaphandle.Ngokuqonda iimfuno zakho ezithile kunye nendlela indawo ebiyelweyo ye-NEMA 4 enokuthi ihlangabezane nazo, unokuqinisekisa ubude obude besixhobo sakho sombane kunye nokusebenza kakuhle.
Gxininisa ibinzana elingundoqo: "NEMA 4 Enclosure"
Inkcazo yeMeta: “Jonga kwiimpawu kunye nokusetyenziswa kwendawo ebiyelweyo ye-NEMA 4 kwisikhokelo sethu esibanzi.Funda indlela le ndlu yomelele, nengenamozulu ikhusela izixhobo zombane kwiindawo ezahlukeneyo, iqinisekisa ubomi obude kunye nokusebenza kakuhle.”
