Ezweni lobunjiniyela kagesi kanye nokufakwa, kubalulekile ukuqonda izingxenye eziqinisekisa ukuphepha nokusebenza kahle. Phakathi kwalezi zingxenye,Izintambo ze-NEMAkanye namathreyi ekhebula e-NEMA adlala indima ebalulekile. Lesi sihloko sizohlola ukuthi ziyini izintambo ze-NEMA kanye nokubaluleka kwamathreyi ekhebula e-NEMA ekufakweni nasekuphathweni kwawo.
I-NEMA imele i-National Electrical Manufacturers Association (NEMA), enesibopho sokubeka izindinganiso zemishini kagesi e-United States. Izintambo ze-NEMA zenzelwe ukuhlangabezana nezindinganiso ezithile zokusebenza nokuphepha ezibekwe yinhlangano. Lezi zintambo zivame ukusetshenziswa ezinhlotsheni ezahlukene zokusebenza, kufaka phakathi izindawo zezimboni, zezentengiselwano, kanye nezindawo zokuhlala.
Izintambo ze-NEMAZibonakala ngokwakhiwa kwazo okuqinile futhi ngokuvamile ziqukethe ama-conductor amaningi afakwe izinto eziqinile. Zenzelwe ukumelana nezimo zemvelo ezinzima futhi zilungele ukusetshenziswa ngaphandle noma ezindaweni lapho ukuchayeka kumswakama, amakhemikhali, noma amazinga okushisa aphezulu kuyinkinga. Izinhlobo zekhebula ezivamile ze-NEMA zifaka phakathi i-NEMA 1, i-NEMA 5, kanye ne-NEMA 6, ngayinye eyenzelwe izidingo ezahlukene ze-voltage kanye nezemvelo.
Uma ufaka izintambo ze-NEMA, kubalulekile ukusebenzisa amathreyi ekhebula le-NEMA.Amathreyi ekhebulaziyisistimu yokusekela ehlinzeka ngendlela yezintambo, ezigcina zihlelekile, ziphephile, futhi zinakekelwa kalula. Amathreyi ekhebula e-NEMA aklanyelwe ukuhlangabezana nezidingo ezihlukile zezintambo ze-NEMA, ukuqinisekisa ukuthi amazinga okuphepha ayahlangatshezwana nokuthi ukuphathwa kwekhebula okuphumelelayo kuyafezwa.
Amathreyi ekhebula le-NEMA afika ngezinto ezahlukahlukene, okuhlanganisa insimbi, i-aluminium, ne-fiberglass, ngayinye enikeza izinzuzo ezahlukene kuye ngokuthi isetshenziswa kanjani. Isibonelo, amathreyi ensimbi aziwa ngamandla awo nokuqina kwawo, okwenza afaneleke kakhulu ekusetshenzisweni okunzima, kuyilapho amathreyi e-aluminium elula futhi engagqwali, okwenza afanelekele izindawo lapho umswakama uyinkinga khona.
Izinzuzo zokusebenzisa ithreyi yekhebula le-NEMA
1. **Ukuhlela**: Amathreyi ekhebula le-NEMA asiza ukugcina izintambo zihlelekile, kunciphisa ingozi yokuxakeka nokulimala. Lolu hlobo lokuhlela lubalulekile ekufakweni okuyinkimbinkimbi ngezintambo eziningi.
2. **Isivikelo**: Ngokuhlinzeka ngesithiyo esingokoqobo, amathreyi ekhebula avikela izintambo ze-NEMA ezingozini zemvelo, ekulimaleni kwemishini, kanye nokuxhumana ngengozi okungabangela ukwehluleka kukagesi noma izingozi zokuphepha.
3. **Kulula ukuzinakekela**: Amakhebula ahlelwe kahle emathileyi, okwenza ukulungiswa nokuxazulula izinkinga kube lula. Ochwepheshe bangabona futhi basebenze ngokushesha kumakhebula athile ngaphandle kokudinga ukuphenya imfucuza.
4. **Ukuthobela**: Ukusebenzisa ithreyi yekhebula le-NEMA kuqinisekisa ukuthi ukufakwa kuhambisana nemithetho kagesi yendawo neyezwe, evame ukudinga imikhuba ethile yokuphathwa kwekhebula ukuze kuthuthukiswe ukuphepha.
5. **Ukuguquguquka**: Amathreyi ekhebula le-NEMA angashintshwa kalula noma anwetshwe njengoba izidingo zesikhungo zishintsha. Lokhu kuvumelana nezimo kubaluleke kakhulu ezindaweni zezimboni lapho imishini kanye nezakhiwo kushintsha khona njalo.
Izintambo ze-NEMA kanye ne-NEMAamathreyi ekhebulaziyingxenye ebalulekile yokufakwa kukagesi kwesimanje. Izintambo ze-NEMA zinikeza amandla adingekayo kanye nokuxhumeka ngenkathi zilandela izindinganiso zokuphepha eziqinile. Okwamanje, amathreyi ezintambo ze-NEMA ahlinzeka ngesisombululo esithembekile sokuhlela nokuvikela lezi zintambo, ukuqinisekisa ukuthobela imithetho, kanye nokwenza lula ukulungiswa. Ukuqonda ubudlelwano phakathi kwalezi zinto ezimbili kubalulekile kunoma ubani ohilelekile kubunjiniyela bukagesi, ukufakwa, noma ukulungiswa, njengoba kusiza ukuthuthukisa ukuphepha nokusebenza kahle kwezinhlelo zikagesi.
