Umahluko phakathi koKuqhushumba-Ubungqina bezibane kunye nezibane eziqhelekileyo

Izinto zokukhanyisa ezingenakugqabhuka ziludidi lwezibane eziyilwe ngeempawu zokukhusela ugqabhuko-dubulo, iphawulwe nge “Eks” uphawu. Ezi zixhobo zineempawu ezithile zokutywinwa kunye nemilinganiselo eyongezelelweyo yokukhusela kwisakhiwo sabo, njengoko kugunyaziswe yimigangatho yesizwe. Ngokungafaniyo nezibane ezingaqhushumbayo, babambelela kwiimfuno ezininzi ezizodwa:

1. Uluhlu olungaqhambukayo, IBanga, kunye neQela lobushushu: Ezi zichazwa ngokwemigangatho yelizwe.

2. Iindidi zoKhuseleko olungaqhambukayo:

Kukho iindidi ezintlanu eziphambili – ingatshi, ukwanda kokhuseleko, uxinzelelo oluhle, engatshisi, kunye nothuli-ubungqina bokudubula. Ziyakwazi nokuba yindibaniselwano yezi ntlobo okanye zibe yimbumba okanye uhlobo olulodwa.

3. Ukukhuselwa koMbane woMbane:

Ihlelwe ngokweendidi ezintathu - I, II, kunye III. Injongo kukuthintela ukutshitshiswa kombane kwiindawo ezifikelelekayo okanye ii-conductor kwiindawo ezahlukeneyo ezinokubakho, enokuthi ivuthe qhuma imixube.

Uhlobo I: Ngokusekelwe kwisiseko sokugquma, iindawo zokuqhuba eziqhele ukuba zingaphili kwaye zifikeleleke ziqhagamshelwe kumqhubi womhlaba okhuselayo kwi-wiring esisigxina..

Uhlobo II: Isebenzisa ukugquma kabini okanye okongeziweyo njengemilinganiselo yokhuseleko, ngaphandle isiseko.

Uhlobo III: Isebenza kumbane okhuselekileyo ongagqithiyo kwi-50V kwaye ayivelisi amandla ombane aphezulu.

Uhlobo 0: Ithembele kuphela kukhuselo olusisiseko.

Uninzi lwezixhobo zokukhanyisa ezikhusela uqhushumbo ziwela phantsi koHlobo loku-I, nabambalwa abaluHlobo lwe-II okanye lwe-III, ezifana nezibane zeplastiki ezikhusela uqhushumbo zonke okanye iitotshi ezinobungqina bokudubula.

4. Inqanaba loKhuseleko lweNdawo:

Iindlela ezahlukeneyo zokukhusela kwi-enclosure zisetyenziselwa ukuthintela ukungena kothuli, izinto eziqinileyo, kunye namanzi, nto leyo enokukhokelela kwintlantsi, ixesha elifutshane, okanye ukuphazamisa ukugquma kombane. Iphawulwe ngu “IP” ilandelwa ngamasuntswana amabini, idijithi yokuqala imele ukhuseleko kuqhagamshelwano, izinto eziqinileyo, okanye uthuli (ukusuka kwi 0-6), okwesibini kuchasene namanzi (ukusuka kwi 0-8). Njengezixhobo ezitywiniweyo, izibane ezingagqabhukiyo zinenqanaba ubuncinane 4 ukukhusela uthuli.

5. Izinto eziphathekayo zoMphezulu oFakayo:

Izibane zangaphakathi ezikhusela ugqabhuko-dubulo zinokuxhonywa kwiindawo eziqhelekileyo ezinokutsha njengeendonga zomthi kunye nesilingi.. Le migangatho mayingagqithi kwisefu ubushushu ngenxa yezixhobo zokukhanya.

Ngokusekelwe ekubeni zinokuxhonywa ngokuthe ngqo kwizinto eziqhelekileyo ezinokutsha, zahlulwe zaba ziindidi ezimbini.

Isishwankathelo – “Zahluke njani izibane ezingagqabhukiyo kwizibane eziqhelekileyo?”: Izibane eziqhelekileyo zisetyenziswa kwiindawo ezingenabungozi ngaphandle ezinokutsha iigesi okanye uthuli. Ngokungafaniyo nezibane ezingenakugqabhuka, abanamabanga kunye neentlobo ezinobungqina bokudubula. Izibane eziqhelekileyo zisebenza ikakhulu kwiinjongo zokukhanyisa, ngelixa izibane ezikhusela uqhushumbo zingaboneleli nje kuphela kodwa zikwabonelela ngokhuseleko lokudubula, ukuqinisekisa ukhuseleko lwabasebenzi kunye nokuthintela umonakalo wepropathi.
