NEMA Izihlanganisi

Izixhumi ze-NEMA zibhekisela kwiiplagi zamandla kunye nezixhobo ezisetyenziswa eNyakatho Melika nakwamanye amazwe alandela imigangatho ebekwe yi-NEMA (i-National Electrical Manufacturers Association).Imigangatho ye-NEMA ihlela iiplagi kunye nezixhobo ngokomlinganiselo we-amperage kunye nomlinganiselo wombane.

Iindidi zezihlanganisi ze-NEMA

Kukho iindidi ezimbini eziphambili zezihlanganisi ze-NEMA: i-blade ethe tye okanye engatshixwayo kunye ne-curved-blade okanye i-twist-locking.Njengoko igama libonisa, iiblade ezithe tye okanye iziqhagamshelo ezingavaliyo zenzelwe ukutsalwa ngaphandle kwezixhobo ngokulula, ezithi, ngelixa zifanelekile, zinokuthetha ukuba unxibelelwano alukhuselekanga.

I-NEMA 1

Iziqhagamshelo ze-NEMA 1 ziiplagi ezine-prong ezimbini kunye nezixhobo ezingenayo isikhonkwane somhlaba, zilinganiswe kwi-125 V kwaye zithandwa kusetyenziso lwasekhaya, njengezixhobo ezikrelekrele kunye nezinye izixhobo zombane ezincinci, ngenxa yoyilo lwazo olubambene kunye nokufumaneka ngokubanzi.

Iiplagi ze-NEMA 1 nazo ziyahambelana neeplagi ezintsha ze-NEMA 5, ezenza zibe lolona khetho luphezulu kubenzi.Ezinye zezona zixhaphakileyo isidibanisi se-NEMA 1 ziquka i-NEMA 1-15P, i-NEMA 1-20P, kunye ne-NEMA 1-30P.

NEMA 5

Izixhumi ze-NEMA ezi-5 zizijikelezo zesigaba sesithathu kunye noxhumo olungathathi hlangothi, uxhulumaniso olushushu, kunye nesiseko socingo.Zilinganiswe kwi-125V kwaye zisetyenziswa ngokuqhelekileyo kwizixhobo ze-IT ezifana neerotha, iikhomputha, kunye nokutshintsha kwenethiwekhi.I-NEMA 5-15P, inguqulo esekelwe kwi-NEMA 1-15P, yenye yezona ziqhagamshelo eziqhelekileyo ezisetyenziswa e-US.

I-NEMA 14

Izihlanganisi ze-NEMA 14 ziziqhagamshelo ezineengcingo ezineengcingo ezishushu ezimbini, intambo engathathi hlangothi, kunye nephini lomhlaba.Ezi zinemilinganiselo ye-amperage ukusuka kwi-15 amps ukuya kwi-60 amps kunye nemilinganiselo yombane we-125/250 volts.

I-NEMA 14-30 kunye ne-NEMA 14-50 zezona ntlobo zixhaphakileyo kwezi plagi, ezisetyenziswa kwiindawo ezingavaliyo ezifana nezomisi kunye noluhlu lombane.Njenge-NEMA 6-50, izihlanganisi ze-NEMA 14-50 nazo zisetyenziselwa ukubiza izithuthi zombane.

I-NEMA TT-30

I-NEMA Travel Trailer (eyaziwa ngokuba yi-RV 30) iqhele ukusetyenziselwa ukudlulisa amandla ukusuka kumthombo wamandla ukuya kwiRV.Ine-orientation efanayo ne-NEMA 5, eyenza ukuba ihambelane nazo zombini izixhobo ze-NEMA 5-15R kunye ne-5-20R.

Ezi ziqhele ukufunyanwa kwiipaki zeRV njengomgangatho wezithuthi zokuzonwabisa.

Okwangoku, iziqhagamshelo zokutshixa zinee-subtypes ezingama-24, ezibandakanya i-NEMA L1 ukuya kuthi ga kwi-NEMA L23 kunye ne-Midget Locking plugs okanye iML.

Ezinye zezona ziqhagamshelo ziqhelekileyo zokutshixa yi-NEMA L5, NEMA L6, NEMA L7, NEMA L14, NEMA L15, NEMA L21, kunye neNEMA L22.

I-NEMA L5

Izihlanganisi ze-NEMA L5 ziziqhagamshelo ezineepali ezimbini ezinesiseko.Ezi zine-voltage rating ye-125 volts, ezenza zilungele ukutshaja kweRV.I-NEMA L5-20 iqhele ukusetyenziselwa iisetingi zemizi-mveliso apho ukungcangcazela kunokwenzeka ukuba kwenzeke, njengakwiinkampu kunye nee-marinas.

I-NEMA L6

I-NEMA L6 zipali ezimbini, izixhumi zocingo ezintathu ngaphandle koxhumo olungathathi hlangothi.Ezi ziqhagamshelo zilinganiswe nokuba yi-208 volts okanye i-240 volts kwaye ziqhele ukusetyenziswa kwiijeneretha (NEMA L6-30).

I-NEMA L7

Izixhumi ze-NEMA L7 zidibanisa iipali ezimbini ezinesiseko kwaye ziqhele ukusetyenziswa kwiinkqubo zokukhanyisa (NEMA L7-20).

I-NEMA L14

Izihlanganisi ze-NEMA L14 zineepali ezintathu, izihlanganisi ezisekelwe phantsi ezinomlinganiselo wombane we-125/250 volts, zidla ngokusetyenziswa kwiinkqubo ezinkulu zeaudio kunye nakwiijenereyitha ezincinci.

I-NEMA L-15

I-NEMA L-15 ziziqhagamshelo ezineepali ezine ezinesiseko socingo.Ezi zizixhobo ezixhathisa imozulu ezidla ngokusetyenziswa kwizicelo zorhwebo ezinzima.

NEMA L21

Izihlanganisi ze-NEMA L21 ziziqhagamshelo eziziipali ezine ezinocingo olusezantsi olubekwe kwi-120/208 volts.Ezi zizixhobo zokuhombisa ezinganyangekiyo ezinetywina elingangeni manzi ezifanelekileyo ukusetyenziswa kwindawo ezifumileyo.

NEMA L22

Izixhumi ze-NEMA L22 zinezithinteli ezine-pole kunye ne-wire grounding kunye ne-voltage rating ye-277/480 volts.Ezi zihlala zisetyenziswa koomatshini boshishino kunye neentambo zejeneretha.

Umbutho weSizwe waBavelisi boMbane uyile ingqungquthela ethiywa kwamagama ukulungelelanisa iziqhagamshelo zeNEMA.

Ikhowudi inamacandelo amabini: inani eliphambi kodwi kunye nenombolo emva kodwi.

Inombolo yokuqala imele ukucwangciswa kweplagi, ebandakanya ukulinganiswa kombane, inani leepali, kunye nenani leengcingo.Izihlanganisi ezingasekelwanga emhlabeni zinenani elifanayo leengcingo kunye neepali kuba azifuni iphini lokumisa.

Jonga le tshathi ingezantsi ngereferensi:

Okwangoku, inani lesibini limele umlinganiselo wangoku.Iiampeges eziqhelekileyo ziyi-15 amps, 20 amps, 30 amps, 50 amps, kunye ne-60 amps.

Ukubeka oku kumbono, i-NEMA 5-15 ikhonkco i-pole-pole, i-wire-wire connector ene-voltage ye-voltage ye-125 volts kunye ne-15 amps yangoku.

Kwezinye izihlanganisi, ingqungquthela yamagama iya kuba noonobumba abongezelelweyo phambi kwenombolo yokuqala kunye / okanye emva kwenombolo yesibini.

Unobumba wokuqala, “L” ufumaneka kuphela kwizihlanganisi zokutshixa ukubonisa ukuba ngenene luhlobo lokutshixa.

Unobumba wesibini, onokuba ngu-“P” okanye “R” ubonisa ukuba isiqhagamshelanisi yi-“Plag” okanye “I-Receptacle”.

Ngokomzekelo, i-NEMA L5-30P iplagi yokukhiya enezibonda ezimbini, iingcingo ezimbini, ukulinganiswa kwangoku kwe-volts ye-125, kunye ne-amperage ye-30 amps.
