Ihuza rya NEMA ryerekeza ku mashanyarazi n'amashanyarazi akoreshwa muri Amerika ya Ruguru no mu bindi bihugu bikurikiza ibipimo byashyizweho na NEMA (Ishyirahamwe ry’inganda zikoresha amashanyarazi).Ibipimo bya NEMA bitondekanya amacomeka hamwe niyakirwa ukurikije igipimo cya amperage hamwe na voltage.
Ubwoko bwa NEMA
Hariho ubwoko bubiri bwingenzi bwihuza NEMA: kugororoka-kugororotse cyangwa kudafunga no kugorora-gukata cyangwa kugoreka.Nkuko izina ribigaragaza, ibyuma bigororotse cyangwa umuhuza udafunze byashizweho kugirango bikurwe mubyakiriwe byoroshye, ibyo, nubwo byoroshye, bishobora kandi gusobanura ko guhuza umutekano bidafite umutekano.
NEMA 1
Ihuza rya NEMA 1 ni ibyuma bibiri-byakira kandi byakira bidafite pin hasi, bipimirwa kuri 125 V kandi bizwi cyane kubikoresha murugo, nko mubikoresho byubwenge nibindi bikoresho bito bya elegitoronike, kubera igishushanyo mbonera cyabyo kandi kiboneka henshi.
Amacomeka ya NEMA 1 nayo arahujwe namashanyarazi mashya ya NEMA 5, bigatuma bahitamo neza kubabikora.Bimwe mubisanzwe NEMA 1 ihuza cyane harimo NEMA 1-15P, NEMA 1-20P, na NEMA 1-30P.
NEMA 5
NEMA 5 ihuza ni ibice bitatu byumuzunguruko ufite aho ubogamiye, ihuza ishyushye, hamwe ninsinga.Bapimwe kuri 125V kandi bikunze gukoreshwa mubikoresho bya IT nka router, mudasobwa, hamwe na enterineti.NEMA 5-15P, verisiyo ishingiye kuri NEMA 1-15P, numwe mubahuza bakunze gukoreshwa muri Amerika.
NEMA 14
NEMA 14 ihuza ni insinga enye zifite insinga ebyiri zishyushye, insinga zidafite aho zibogamiye, hamwe nubutaka.Izi zifite amanota ya amperage kuva kuri 15 amps kugeza kuri 60 amps hamwe na voltage ya 125/250 volt.
NEMA 14-30 na NEMA 14-50 nubwoko busanzwe bwibi byuma, bikoreshwa muburyo budafunze nko mu byuma n'amashanyarazi.Kimwe na NEMA 6-50, NEMA 14-50 ihuza nayo ikoreshwa mukwishyuza ibinyabiziga byamashanyarazi.
NEMA TT-30
Urugendo rwa NEMA (ruzwi nka RV 30) rusanzwe rukoreshwa mu kwimura ingufu ziva mumashanyarazi zikagera kuri RV.Ifite icyerekezo kimwe na NEMA 5, ituma ihuza na NEMA 5-15R na 5-20R yakira.
Ibi bikunze kuboneka muri parike ya RV nkibipimo byimodoka zidagadura.
Hagati aho, gufunga abahuza bifite subtypes 24, zirimo NEMA L1 kugeza kuri NEMA L23 kimwe na Midget Locking plug cyangwa ML.
Bimwe mubihuza bifunga cyane ni NEMA L5, NEMA L6, NEMA L7, NEMA L14, NEMA L15, NEMA L21, na NEMA L22.
NEMA L5
NEMA L5 ihuza ni pole ebyiri ihuza hamwe nubutaka.Izi zifite voltage ya volt 125, bigatuma ikwiranye na RV.NEMA L5-20 isanzwe ikoreshwa mubikorwa byinganda aho ihindagurika rishobora kubaho, nko mubigo na marine.
NEMA L6
NEMA L6 ni pole ebyiri, ihuza insinga eshatu zidafite aho zibogamiye.Ihuza ryapimwe kuri 208 volt cyangwa 240 volt kandi bikunze gukoreshwa kuri generator (NEMA L6-30).
NEMA L7
Ihuza rya NEMA L7 ni ibice bibiri bihuza hamwe nubutaka kandi bikoreshwa muburyo bwo gucana (NEMA L7-20).
NEMA L14
Ihuza rya NEMA L14 ni pole eshatu, ihuza hasi ifite voltage ya 125/250 volt, mubisanzwe ikoreshwa kuri sisitemu nini y'amajwi kimwe no kuri generator nto.
NEMA L-15
NEMA L-15 ni umuhuza wa pole enye ufite insinga.Ibi nibihe byihanganira ikirere byakunze gukoreshwa mubikorwa byubucuruzi biremereye.
NEMA L21
NEMA L21 ihuza ni bine-pole ihuza hamwe na insinga zometse kuri volt 120/208.Ibi nibishobora kwihanganira tamper hamwe na kashe yamazi ikwiranye nogukoresha ahantu hatose.
NEMA L22
Ihuza rya NEMA L22 rifite ibice bine bya pole hamwe nubutaka bwumurongo hamwe na voltage ya 277/480 volt.Ibi bikunze gukoreshwa kumashini zinganda ninsinga za generator.
Ishyirahamwe ry’abakora amashanyarazi mu gihugu ryateguye amasezerano yo kwita izina kugira ngo uhuze NEMA.
Kode ifite ibice bibiri: umubare mbere yumurongo numubare nyuma yumurongo.
Umubare wambere ugereranya amacomeka, arimo igipimo cya voltage, umubare winkingi, numubare winsinga.Ihuza ridafite aho rihuriye rifite insinga ninkingi zingana kuko zidasaba pin.
Reba imbonerahamwe ikurikira kugirango ubone ibisobanuro:
Hagati aho, umubare wa kabiri ugereranya urutonde rwubu.Amperage isanzwe ni 15 amps, 20 amps, 30 amps, 50 amps, na 60 amps.
Kugirango ubishyire mubikorwa, umuhuza wa NEMA 5-15 ni pole ebyiri, umuyoboro winsinga ebyiri hamwe na voltage ya volt 125 hamwe nubu 15 amps.
Kuri bamwe bahuza, amazina yo kwita izina azagira inyuguti zinyongera mbere yumubare wambere na / cyangwa nyuma yumubare wa kabiri.
Inyuguti ya mbere, “L” iboneka gusa muguhuza abahuza kugirango yerekane ko mubyukuri ari ubwoko bwo gufunga.
Inyuguti ya kabiri, ishobora kuba “P” cyangwa “R” yerekana niba umuhuza ari “Gucomeka” cyangwa “Kwakira”.
Kurugero, NEMA L5-30P nigikoresho gifunga gifite inkingi ebyiri, insinga ebyiri, igipimo cyubu cya volt 125, hamwe na amperage ya 30 amps.
