Izixhumi ze-NEMA

Izixhumi ze-NEMA zibhekisela kumapulaki namandla asetshenziswa eNyakatho Melika nakwamanye amazwe alandela izindinganiso ezibekwe yi-NEMA (National Electrical Manufacturers Association).Izindinganiso ze-NEMA zihlukanisa amapulaki nezinto zokudonsa ngokuya ngesilinganiso se-amperage kanye nesilinganiso sikagesi.

Izinhlobo zezixhumi ze-NEMA

Kunezinhlobo ezimbili eziyinhloko zezixhumi ze-NEMA: i-straight-blade noma engakhiyi kanye ne-curved-blade noma i-twist-locking.Njengoba igama liphakamisa, ama-blade aqondile noma izixhumi ezingakhiyi ziklanyelwe ukuthi zikhishwe ezitsheni kalula, okuthi, nakuba zilula, zingasho nokuthi uxhumano aluvikelekile.

I-NEMA 1

Izixhumi ze-NEMA 1 zingamapulagi ane-prong ezimbili kanye nezinsiza ezingenalo iphini eliphansi, zilinganiselwe ku-125 V futhi zidumile ngokusetshenziswa kwasendlini, njengakuzinto zikagesi ezihlakaniphile nezinye izinto zikagesi ezincane, ngenxa yokwakheka kwazo okuhlangene nokutholakala okubanzi.

Amapulagi e-NEMA 1 nawo ayahambisana namapulaki e-NEMA 5 amasha, awenza abe yinketho ephezulu kubakhiqizi.Ezinye izixhumi ezivame kakhulu ze-NEMA 1 zifaka i-NEMA 1-15P, i-NEMA 1-20P, ne-NEMA 1-30P.

I-NEMA 5

Izixhumi ze-NEMA 5 ziyiziyingi zezigaba ezintathu ezinoxhumo olungathathi hlangothi, uxhumano olushisayo, kanye nokugxiliswa kwentambo.Zikalwe ku-125V futhi zivame ukusetshenziswa kumishini ye-IT njengamarutha, amakhompyutha, namaswishi enethiwekhi.I-NEMA 5-15P, inguqulo esekelwe phansi ye-NEMA 1-15P, ingenye yezixhumi ezivame ukusetshenziswa e-US.

I-NEMA 14

Izixhumi ze-NEMA 14 ziyizixhumi ezinezintambo ezine ezinezintambo ezimbili ezishisayo, intambo emaphakathi, nephinikhodi ephansi.Lezi zinezilinganiso ze-amperage ezisukela ku-15 amps kuya ku-60 amps kanye nezilinganiso zamandla kagesi angu-125/250 volts.

I-NEMA 14-30 kanye ne-NEMA 14-50 wuhlobo oluvame kakhulu lwalawa mapulagi, asetshenziswa kuzilungiselelo ezingakhiyiwe njengakomisa okomisa kanye nebanga likagesi.Njenge-NEMA 6-50, izixhumi ze-NEMA 14-50 nazo zisetshenziselwa ukushaja izimoto zikagesi.

I-NEMA TT-30

I-NEMA Travel Trailer (eyaziwa ngokuthi i-RV 30) ivamise ukusetshenziselwa ukudlulisa amandla ukusuka emthonjeni wamandla ukuya ku-RV.Inomumo ofanayo nowe-NEMA 5, okuyenza ihambisane nazo zombili izinsiza ze-NEMA 5-15R kanye ne-5-20R.

Lezi zivame ukutholakala emapaki e-RV njengezinga lezimoto zokungcebeleka.

Ngaleso sikhathi, izixhumi zokukhiya zinezinhlobo ezincane ezingu-24, ezihlanganisa i-NEMA L1 kufika ku-NEMA L23 kanye namapulagi okukhiya iMidget noma i-ML.

Ezinye izixhumi ezivame kakhulu zokukhiya i-NEMA L5, NEMA L6, NEMA L7, NEMA L14, NEMA L15, NEMA L21, ne-NEMA L22.

I-NEMA L5

Izixhumi ze-NEMA L5 ziyizixhumi ezinezigxobo ezimbili ezinesisekelo.Lawa anesilinganiso sikagesi esingu-125 volts, okuwenza afanelekele ukushajwa kwe-RV.I-NEMA L5-20 ivamise ukusetshenziselwa izilungiselelo zezimboni lapho ukudlidliza kungenzeka kwenzeke, njengasezindaweni zokukhempa nama-marinas.

I-NEMA L6

I-NEMA L6 iyizigxobo ezimbili, izixhumi ezinezintambo ezintathu ngaphandle koxhumano olumaphakathi.Lezi zixhumi zilinganiselwe ku-208 volts noma 240 volts futhi ngokuvamile zisetshenziselwa amajeneretha (NEMA L6-30).

I-NEMA L7

Izixhumi ze-NEMA L7 ziyizixhumi ezinezigxobo ezimbili ezinesisekelo futhi zivame ukusetshenziselwa izinhlelo zokukhanyisa (NEMA L7-20).

I-NEMA L14

Izixhumi ze-NEMA L14 zinezigxobo ezintathu, izixhumi ezisekelwe phansi ezinesilinganiso sikagesi esingu-125/250 volts, ngokuvamile zisetshenziswa ezinhlelweni ezinkulu zomsindo kanye nakumajeneretha amancane.

I-NEMA L-15

I-NEMA L-15 izixhumi ezinezigxobo ezine ezinesisekelo socingo.Lezi yizinto zokuthwala ezimelana nesimo sezulu ezivame ukusetshenziselwa izinhlelo zokusebenza zokuthengisa ezisindayo.

I-NEMA L21

Izixhumi ze-NEMA L21 ziyizixhumi ezinezigxobo ezinezisekelo ezinezintambo ezilinganiselwe ku-120/208 volts.Lezi yizinto zokudonsa ezikwazi ukumelana nokuphazamiseka ezinophawu olungangeni manzi ezifanele ukusetshenziswa ezindaweni eziswakeme.

I-NEMA L22

Izixhumi ze-NEMA L22 zinokucushwa kwezigxobo ezine ezinezintambo eziphansi kanye nesilinganiso sikagesi esingu-277/480 volts.Lezi zivame ukusetshenziswa emishinini yezimboni kanye nezintambo ze-generator.

I-National Electrical Manufacturer's Association isungule umhlangano wokuqamba amagama ukuze kufane izixhumi ze-NEMA.

Ikhodi inezingxenye ezimbili: inombolo ngaphambi kodeshi nenombolo ngemva kodeshi.

Inombolo yokuqala imelela ukucushwa kwepulaki, okuhlanganisa isilinganiso sikagesi, inani lezigxobo, nenani lezintambo.Izixhumi ezingagxiliwe zinenani elifanayo lezintambo nezigxobo ngenxa yokuthi azidingi iphinikhodi.

Bheka ishadi elingezansi ukuze uthole inkomba:

Ngaleso sikhathi, inombolo yesibili imelela isilinganiso samanje.Ama-ampeges ajwayelekile angama-amps angu-15, ama-amps angu-20, ama-amps angu-30, angu-50 nama-amps angu-60.

Ukubeka lokhu kumbono ofanele, isixhumi se-NEMA 5-15 siyizigxobo ezimbili, isixhumi esinezintambo ezimbili esinesilinganiso sikagesi esingu-125 volts kanye nesilinganiso samanje esingu-15 amps.

Kwezinye izixhumi, ukuqamba amagama kuzoba nezinhlamvu ezengeziwe ngaphambi kwenombolo yokuqala kanye/noma ngemva kwenombolo yesibili.

Uhlamvu lokuqala, “L” lutholakala kuphela kuzixhumi zokukhiya ukukhombisa ukuthi luhlobo lokukhiya ngempela.

Uhlamvu lwesibili, olungase lube “P” noma “R” lubonisa ukuthi isixhumi “siyipulagi” noma “Isithako”.

Isibonelo, i-NEMA L5-30P iyipulaki yokukhiya enezigxobo ezimbili, izintambo ezimbili, isilinganiso samanje esingu-125 volts, kanye ne-amperage yama-amps angu-30.
