Kwihlabathi lobunjineli bombane kunye nokufakelwa, kubalulekile ukuqonda izinto eziqinisekisa ukhuseleko kunye nokusebenza kakuhle. Phakathi kwezi zinto,Iintambo ze-NEMAkwaye iitreyi zekhebula ze-NEMA zidlala indima ebalulekileyo. Eli nqaku liza kuhlola ukuba ziyintoni iintambo ze-NEMA kunye nokubaluleka kweetreyi zekhebula ze-NEMA ekufakweni nasekulawulweni kwazo.
I-NEMA imele iNational Electrical Manufacturers Association (NEMA), enoxanduva lokumisela imigangatho yezixhobo zombane eMelika. Iintambo ze-NEMA zenzelwe ukuhlangabezana nemigangatho ethile yokusebenza kunye nokhuseleko ebekwe yintlangano. Ezi ntambo zihlala zisetyenziswa kwiindlela ezahlukeneyo zokusebenza, kubandakanya nezakhiwo zoshishino, zorhwebo, kunye neendawo zokuhlala.
Iintambo ze-NEMAZibonakala ngokwakhiwa kwazo okuqinileyo kwaye zihlala ziqulathe ii-conductors ezininzi ezigqunywe ngezinto ezihlala ixesha elide. Zenzelwe ukumelana neemeko ezinzima zokusingqongileyo kwaye zilungele ukusetyenziswa ngaphandle okanye kwiindawo apho ukuchatshazelwa kukufuma, iikhemikhali, okanye amaqondo obushushu aphezulu kuyingxaki. Iindidi zekhebula ze-NEMA eziqhelekileyo ziquka i-NEMA 1, i-NEMA 5, kunye ne-NEMA 6, nganye yenzelwe iimfuno ezahlukeneyo ze-voltage kunye nokusingqongileyo.
Xa ufaka iintambo ze-NEMA, kubalulekile ukusebenzisa iitreyi zentambo ze-NEMA.Iitreyi zekhebulayinkqubo yenkxaso ebonelela ngendlela yeentambo, ezigcina zihlelekile, zikhuselekile, kwaye kulula ukuzigcina zicocekile. Iitreyi zeentambo ze-NEMA zenzelwe ukuhlangabezana neemfuno ezikhethekileyo zeentambo ze-NEMA, ukuqinisekisa ukuba imigangatho yokhuseleko iyafezekiswa kwaye ulawulo lweentambo olusebenzayo luyafezekiswa.
Iitreyi zekhebula ze-NEMA ziza ngezixhobo ezahlukeneyo, kuquka intsimbi, i-aluminium, kunye ne-fiberglass, nganye kuzo inika izibonelelo ezahlukeneyo ngokuxhomekeke kwisicelo. Umzekelo, iitreyi zentsimbi zaziwa ngamandla azo kunye nokuqina kwazo, nto leyo eyenza ukuba zilungele ukusetyenziswa kakhulu, ngelixa iitreyi ze-aluminium zilula kwaye azinamhlwa, nto leyo eyenza ukuba zifaneleke kwiindawo apho ukufuma kuyinto exhalabisayo.
Iingenelo zokusebenzisa itreyi yekhebula ye-NEMA
1. **Ulungiselelo**: Iitreyi zekhebula ze-NEMA zinceda ukugcina iintambo zihlelekile, zinciphisa umngcipheko wokuxinana kunye nomonakalo. Olu hlobo lolungiselelo lubalulekile kwiindawo ezinzima zokufakelwa iintambo ezininzi.
2. **Ukhuseleko**: Ngokubonelela ngomqobo obonakalayo, iitreyi zekhebula zikhusela iintambo ze-NEMA kwiingozi zokusingqongileyo, umonakalo woomatshini, kunye nokudibana ngengozi okunokubangela ukungasebenzi kakuhle kombane okanye iingozi zokhuseleko.
3. **Kulula ukuzilungisa**: Iintambo zicwangciswe kakuhle kwiitreyi, nto leyo eyenza ukulungiswa nokusombulula iingxaki kube lula. Iingcali ziyakwazi ukubona nokusebenzela iintambo ezithile ngokukhawuleza ngaphandle kokufuna ukuphanda phakathi kwezinto ezingafunekiyo.
4. **Ukuthobela**: Ukusebenzisa itreyi yekhebula ye-NEMA kuqinisekisa ukuba ukufakelwa kuyahambelana neekhowudi zombane zasekuhlaleni nezesizwe, ezidla ngokufuna iindlela ezithile zolawulo lwekhebula ukuphucula ukhuseleko.
5. **Ukuguquguquka**: Iitreyi zekhebula ze-NEMA zinokuguqulwa okanye zandiswe ngokulula njengoko kufuneka indawo itshintshe. Oku kuhlengahlengiswa kubaluleke kakhulu kwiindawo zoshishino apho izixhobo kunye noyilo lutshintsha rhoqo.
Iintambo ze-NEMA kunye ne-NEMAiitreyi zekhebulaziyinxalenye ebalulekileyo yokufakelwa kombane wanamhlanje. Iintambo ze-NEMA zibonelela ngamandla afunekayo kunye noqhagamshelo ngelixa zilandela imigangatho yokhuseleko engqongqo. Okwangoku, iitreyi zentambo ze-NEMA zibonelela ngesisombululo esithembekileyo sokuhlela nokukhusela ezi ntambo, ukuqinisekisa ukuthotyelwa kwemithetho, kunye nokwenza lula ukugcinwa kwazo. Ukuqonda ubudlelwane phakathi kwezi zinto zimbini kubalulekile kuye nabani na obandakanyeka kubunjineli bombane, ukufakelwa, okanye ukugcinwa, njengoko kunceda ukuphucula ukhuseleko kunye nokusebenza kakuhle kweenkqubo zombane.
