NEMA Connectors

NEMA connectors zvinoreva maplugs emagetsi nemidziyo inoshandiswa kuNorth America nedzimwe nyika dzinotevedza zviga zvakatarwa neNEMA (National Electrical Manufacturers Association).NEMA mazinga anoronga mapulagi uye zvigadziro zvinoenderana neamperage rating uye voltage rating.

Mhando dzeNEMA connectors

Kune mhando mbiri huru dzeNEMA zvibatanidza: yakatwasuka-blade kana isina-kukiya uye curved-blade kana twist-locking.Sezvinoratidzwa nezita racho, mashizha akatwasuka kana asina-kukiya majoini akagadzirwa kuti abudiswe kunze kwemidziyo zviri nyore, izvo, kana zviri nyore, zvinogonawo kureva kuti kubatana hakuna kuchengeteka.

NEMA 1

NEMA 1 maconnector ma-prong-prong plugs and receptacles asina pini yepasi, akayerwa pa125 V uye anonyanya kufarirwa kushandiswa kwemumba, senge mumidziyo yakangwara nemimwe midziyo midiki yemagetsi, nekuda kwecompact dhizaini uye kuwanikwa kwakakura.

NEMA 1 plugs zvakare inoenderana neatsva NEMA 5 plugs, ayo anoaita sarudzo yepamusoro yevagadziri.Zvimwe zvinonyanyozivikanwa zveNEMA 1 connector zvinosanganisira NEMA 1-15P, NEMA 1-20P, uye NEMA 1-30P.

NEMA 5

NEMA 5 maconnectors ndiwo matatu-chikamu maseketi ane kwaakarerekera kubatana, chinopisa chinongedzo, uye waya yekumisa.Iwo akatemerwa pa125V uye anowanzo shandiswa mumidziyo yeIT senge marouters, makomputa, uye network switch.NEMA 5-15P, iyo yakavakirwa vhezheni yeNEMA 1-15P, ndeimwe yeanonyanya kubatanidza anoshandiswa muUS.

NEMA 14

NEMA 14 zvinobatanidza zvikochekera zvina-waya zvine waya mbiri dzinopisa, waya isina kwayakarerekera, uye pini yepasi.Aya ane maamperage ratings kubva pa15 amps kusvika 60 amps uye voltage ratings ye125/250 volts.

NEMA 14-30 neNEMA 14-50 ndidzo dzinonyanyozivikanwa mhando dzemapulagi aya, anoshandiswa mumagadzirirwo asiri ekuvhara senge mumaomesa nemagetsi.Kufanana neNEMA 6-50, NEMA 14-50 majoini anoshandiswawo kuchaja mota dzemagetsi.

NEMA TT-30

NEMA Travel Trailer (inozivikanwa seRV 30) inowanzoshandiswa kutamisa simba kubva kumagetsi kuenda kuRV.Iyo ine yakatarisa yakafanana neNEMA 5, inoita kuti ienderane nezvose zviri zviviri NEMA 5-15R uye 5-20R midziyo.

Aya anowanzo kuwanikwa mumapaki eRV seyero yemotokari dzekuvaraidza.

Zvichakadaro, makiyi ekubatanidza ane makumi maviri nemana madiki, ayo anosanganisira NEMA L1 kusvika kuNEMA L23 pamwe neMidget Locking plugs kana ML.

Zvimwe zvinonyanya kuvharika zvinobatanidza NEMA L5, NEMA L6, NEMA L7, NEMA L14, NEMA L15, NEMA L21, neNEMA L22.

NEMA L5

NEMA L5 ma-connectors ma-pole-pole connectors ane pasi.Aya ane voltage rating ye125 volts, ichiita kuti ive yakakodzera kubhadharisa RV.Iyo NEMA L5-20 inowanzo shandiswa kugadziridza maindasitiri uko kudedera kungangoitika, semumisasa nemamarina.

NEMA L6

NEMA L6 ane mapango maviri, matatu-waya zvinongedzo zvisina kwazvakarerekera.Aya ma connector akaiswa pa 208 volts kana 240 volts uye anowanzo shandiswa majenareta (NEMA L6-30).

NEMA L7

NEMA L7 connectors ma-pole-pole connectors ane grounding uye anowanzo shandiswa pakuvheneka masisitimu (NEMA L7-20).

NEMA L14

NEMA L14 maconnectors ane mapango matatu, akaiswa pasi ane voltage rating ye125/250 volts, anowanzo shandiswa pamaodhiyo mahombe masisitimu pamwe chete nemajenareta madiki.

NEMA L-15

NEMA L-15 zvikochekeri zvina-mapango zvine wire pasi.Izvi zvigadziko zvinodzivirira mamiriro ekunze izvo zvinowanzoshandiswa kune zvinorema-basa rekutengesa zvikumbiro.

NEMA L21

NEMA L21 connectors ndiwo mana-pole connectors ane waya grounding yakarongwa pa120/208 volts.Izvi zvigadziko zvinodzivirirwa zvine chisimbiso chisina mvura chakakodzera kushandisa munzvimbo dzine unyoro.

NEMA L22

NEMA L22 connectors ine mana-pole configuration ine waya inodzika uye voltage reti ye277/480 volts.Izvi zvinowanzo shandiswa pamichina yeindasitiri uye tambo dzejenareta.

Sangano reNational Electrical Manufacturer's Association rakaronga gungano rekupa mazita kuti rigadzirise majoikiniki eNEMA.

Kodhi ine zvikamu zviviri: nhamba isati yasvika uye nhamba mushure medeshi.

Nhamba yekutanga inomiririra plug configuration, iyo inosanganisira voltage rating, nhamba yemapuranga, uye nhamba yewaya.Unground connectors ane nhamba imwechete yewaya nemapango nekuti haadi pini yekumisa.

Ona chati iri pazasi kuti utarise:

Zvichakadaro, nhamba yechipiri inomiririra chiyero chazvino.Mamiriro akaenzana 15 amps, 20 amps, 30 amps, 50 amps, uye 60 amps.

Kuisa izvi mumaonero, NEMA 5-15 connector i-pole-pole, two-waya connector ine voltage rating ye125 volts uye yazvino rating ye15 amps.

Kune vamwe vanobatanidza, gungano rezita richava nemamwe mavara pamberi penhamba yekutanga uye / kana mushure mechipiri nhamba.

Vara rekutanga, “L” rinongowanikwa mumakiyi ekubatanidza kuratidza kuti zvechokwadi imhando yekukiya.

Tsamba yechipiri, inogona kunge iri "P" kana "R" inoratidza kana chinongedzo chiri "Plug" kana "Receptacle".

Semuenzaniso, NEMA L5-30P ipulagi yekukiya ine mapango maviri, waya mbiri, chiyero chemazuva ano che125 volts, uye amperage ye30 amps.
