Njengoko sisazi, kukho imigangatho yobugcisa emininzi yokulinganisa iiklasi zeendawo ezivaliweyo zombane kunye nokuba zixhathisa kangakanani ukuphepha izinto ezithile.Ukulinganisa kwe-NEMA kunye nokulinganisa kwe-IP zindlela ezimbini ezahlukeneyo zokuchaza idigri zokukhusela kwizinto ezifana namanzi kunye nothuli, nangona basebenzisa iindlela ezahlukeneyo zokuvavanya kunye neeparitha ukuchaza iintlobo zabo zokuvala.Zombini ziyimilinganiselo efanayo, kodwa zisenomohluko othile.
Umbono we-NEMA ubhekiselele kuMbutho weSizwe waBavelisi boMbane (NEMA) owona mbutho mkhulu worhwebo wabenzi bezixhobo zombane eWashington DC, eUnited States.Ipapasha idlula imigangatho engama-700, izikhokelo, kunye namaphepha obugcisa.IMarjory yemigangatho zezo zibiyelweyo zombane, iimotor kunye nocingo lwemagnethi, iiplagi zeAC, kunye nezixhobo.Ngapha koko, iziqhagamshelo ze-NEMA azikho nje kuphela kuMntla Merika kodwa zikwasetyenziswa nangamanye amazwe.Inqaku le-NEMA ngumbutho ongabandakanyeki ekuvunyweni nasekuqinisekiseni iimveliso.Amanqaku e-NEMA abonisa ukukwazi kwendawo ebiyelweyo ukukwazi ukumelana neemeko ezithile zokusingqongileyo ukuqinisekisa ukhuseleko, ukuhambelana, kunye nokusebenza kweemveliso zombane.Iireyithingi aziqhelekanga zisetyenziswa kwizixhobo eziphathwayo kwaye zisetyenziswa okokuqala kwiindawo ezivaliweyo.Umzekelo, ukukala kwe-NEMA kuya kufakwa kwibhokisi yombane esisigxina exhonywe ngaphandle, okanye kwindawo ebiyelweyo esisigxina esetyenziselwa ukubeka indawo yofikelelo engenazingcingo.Uninzi lweendawo ezivaliweyo zinikwe ireyithingi yokusetyenziswa kwimeko-bume yangaphandle ibandakanya umlinganiselo we-NEMA 4.Amanqanaba asuka kwi-NEMA 1 ukuya kwi-NEMA 13. Iireyithingi ze-NEMA (Isihlomelo I) zineemfuno ezahlukeneyo ezingqongqo zokuhambelana nokukhuselwa kumkhenkce wangaphandle, izinto ezidliwayo, ukuntywiliselwa kwe-oyile, uthuli, amanzi, njl njl. Ezi mfuno zovavanyo azifane zisetyenziswe izixhobo eziphathwayo xa kuthelekiswa ezisisigxina.
I-International Electrotechnical Commission (IEC) ngumbutho wemigangatho yamazwe ngamazwe olungiselela kwaye upapashe imigangatho yamazwe ngamazwe yombane, i-elektroniki, kunye nobuchwepheshe obunxulumeneyo.Imigangatho ye-IEC ibandakanya uluhlu olukhulu lobugcisa obuvela kumbane, ukuhanjiswa, kunye negalelo kwizixhobo zeofisi kunye nezixhobo zasekhaya, ii-semiconductors, iibhetri, namandla elanga, njl. njl. amacandelo ahambelana nemigangatho yamazwe ngamazwe.Omnye wemigangatho esebenzayo ebizwa ngokuba yiKhowudi yoKhuseleko lokuNgena (IP) ichazwa ngumgangatho we-IEC 60529 ohlela kwaye ulinganise inqanaba lokhuseleko olubonelelwa ngoomatshini kunye nezivalo zombane ngokuchasene nokungena, uthuli, ukudibana ngengozi, kunye namanzi.Iqulathe amanani anemivo emibini.Idijithi yokuqala ibonisa inqanaba lokhuseleko olunikezelwa yi-enclosure ngokuchasene nokufikelela kwiindawo ezinobungozi ezifana neendawo ezihambayo, kunye nokutshintsha.Kwakhona, ukufikelela kwezinto eziqinileyo kuya kuboniswa njengomgangatho ukusuka ku-0 ukuya ku-6. Idijithi yesibini ibonisa inqanaba lokhuseleko olunikezelwa yi-enclosure ngokuchasene nokungena okuyingozi kwamanzi okuya kuqinisekiswa kwinqanaba ukusuka ku-0 ukuya ku-8. Ukuba kukho Akukho mfuneko ichazwe kuyo nayiphi na kwezi ndawo, unobumba X uya kutshintshwa ngenani elingqinelanayo.
Ngokusekelwe kolu lwazi lungentla, siyazi ukuba i-NEMA kunye ne-IP ziyimilinganiselo yokhuseleko oluvalelekileyo.Ukwahlula phakathi kokulinganisa kwe-NEMA kunye nokulinganisa kwe-IP apho yangaphambili ibandakanya ukukhuselwa komkhenkce wangaphandle, izinto ezidliwayo, ukuntywiliselwa kweoli, uthuli, kunye namanzi, ngelixa ukugqibela kubandakanya ukukhuselwa kothuli namanzi.Kuthetha ukuba i-NEMA igubungela ngakumbi imigangatho yokhuseleko eyongezelelweyo efana nezixhobo zomhlwa kwi-IP.Ngamanye amazwi, akukho kuguqulwa ngokuthe ngqo phakathi kwabo.Imigangatho ye-NEMA yanelisekile okanye igqithile kwiireyithingi ze-IP.Ngakolunye uhlangothi, ukulinganisa kwe-IP akuhambelani nemigangatho ye-NEMA, kuba i-NEMA ibandakanya iimpawu ezongezelelweyo zemveliso kunye novavanyo olungabonelelwanga yinkqubo yokukala ye-IP.Kwinkalo yesicelo, i-NEMA ibonelelwa ngokubanzi kwizicelo zemizi-mveliso kwaye isetyenziswa ikakhulu eMntla Melika, ngelixa iireyithingi ze-IP zinokugubungela iqela lezicelo kwihlabathi jikelele.
Ngamafutshane, kukho ulungelelwaniso phakathi kohlengahlengiso lwe-NEMA kunye neereyithingi ze-IP.Nangona kunjalo, oku kuyinkxalabo kuthuli namanzi.Nangona kunokwenzeka ukuthelekisa ezi mvavanyo zimbini, uthelekiso luhambelana kuphela nokhuseleko olunikezelwa eluthulini kunye nokufuma.Abanye abavelisi bezixhobo eziphathwayo baya kubandakanya ukalisho lwe-NEMA kwiinkcukacha zabo, kwaye kubalulekile ukuqonda ukuba inkcazo ye-NEMA inxibelelana njani nemilinganiselo yayo ye-IP.
