Isigaba sesi-3 – Iqondwa kanjani incazelo “yensiza yekilasi 0”
QAPHELA izinto zikagesi zeSigaba 0 zinendawo ebiyelwe yezinto ezivalelayo ezingase zakhe ingxenye noma yonke into eyisisekelo, noma indawo ebiyelwe yensimbi ehlukaniswa nezingxenye ezibukhoma ngokufakwa okufanele. Uma into esetshenziswayo evalekile yezinto ezivikelayo inenhlinzeko yezingxenye zangaphakathi ze- earthing, ibhekwa njengento esetshenziswayo yekilasi I noma isisetshenziswa sekilasi 0I.
Lolu hlobo lukagesi alunaso isisetshenziswa somhlaba esivikelayo, futhi ngesikhathi esifanayo, ungqimba olulodwa kuphela lokufakwa kwe-insulation olugoqa izingxenye ezibukhoma, noma ungqimba lokuvala lusetshenziselwa ukwehlukanisa umsebenzisi ezingxenyeni ezibukhoma. Amazwe amaningi awazamukeli izinto zikagesi zeClass 0. Amazwe athile kuphela anamandla kagesi aphambili (i-voltage elinganiselwe) engu-100V njenge-Japan ne-120V njenge-United States ne-Mexico amukela izinto zikagesi ze-Class 0. Kudingekile ukusho lapha ukuthi ukuze kuzuzwe amandla afanayo okufaka (isibonelo, i-heater yegumbi ene-input yamandla elinganiselwe ye-3000W), i-voltage ephansi elinganiselwe, kuzoba mkhulu ukusebenza okuhambisanayo. Ngokuphambene nalokho, uma i-voltage elinganiselwe iphezulu, ukufakwa okuhambisanayo kwamanje kuzoba phansi. Endabeni yamanje ephezulu, ukushisa kwezingxenye eziphethe okwamanje kumkhiqizo kuzoba nzima kakhulu, futhi amathuba ahambisanayo omlilo azoba mkhulu, ngakho-ke izidingo zokuvikela umlilo zizoba nzima kakhulu. Endabeni ye-voltage ephansi yamanje kanye nephezulu, ukushisisa kwezingxenye eziphethe njengamanje akukona okungathí sina, kodwa ngenxa ye-voltage ephezulu, amathuba okuqhekeka kwe-insulation kuba mkhulu, futhi izidingo ezihambisanayo zokushaqeka kukagesi ziqine kakhulu. Kungakho uchungechunge lwamazinga e-IEC 60335 lunezidingo eziphakeme kangaka zokuvikela ukushaqeka kukagesi. Ababhali abakhulu bezinga le-IEC 60335 bangochwepheshe abavela emazweni ane-voltage elinganiselwe engu-220-240V, kuyilapho uchungechunge lwamazinga e-US UL lunezidingo eziqinile nakakhulu zokuvikela umlilo. Imvamisa, alukho umshini onjalo lapho zonke izingxenye ezibukhoma zivikelwe ngokufakwa okuyisisekelo kuphela. Kuvamile ukuthi izilinganiso eziningi zokuvikela ngokumelene nokushaqeka kukagesi zisengakwazi ukuhlangabezana nezidingo ze-insulation ephindwe kabili noma ukufakwa okuqinisiwe. Yebo, kukhona futhi ukufakwa okuyisisekelo kanye nezakhiwo zokuvikela phansi. Isimo esivamile ukuthi kunongqimba olulodwa kuphela lwe-wire sheath entanjeni yokuhlinzeka, futhi izinga lokuvikela ledivayisi linqunywa ukuvaleka okuyisisekelo kwentambo yokuhlinzeka, okungukuthi, izinga eliphansi lokuvikela lekilasi 0.
Izithombe ezimbili ezilandelayo zikhombisa ulwazi lwentambo yokuhlinzeka yemishini yeklasi 0. Enye ikhombisa umdwebo wohlelo kanti enye ikhombisa intambo yokunikezela enepulaki.
