Into esetshenziswayo yekilasi II: into esetshenziswayo lapho ukuvikeleka kokushaqeka kukagesi kungancikile insulation eyisisekelo kuphela kodwa lapho kunikezwa khona izinyathelo zokuphepha ezengeziwe, njengokuthi double insulation noma reinforced insulation, akukho ukuhlinzekwa komhlaba ovikelayo noma ukuthembela ezimeni zokufakwa. QAPHELA 1 Isisetshenziswa esinjalo singaba ngolunye kulezi zinhlobo ezilandelayo:– into esetshenziswayo enendawo evalekile ehlala isikhathi eside neqhubekayo yezinto ezivalelayo ezimboza…
clearance: ibanga elifushane emoyeni phakathi kwezingxenye ezimbili ze-conductive noma phakathi kwengxenye ye-conductive kanye ne-indawo efinyelelekayo. Ukuhlanzeka kuwumqondo obaluleke kakhulu. Ukuze siqonde imvume, sidinga ukuphinda sikusho ukuthi akukho lutho oluvalwe ngokuphelele, futhi umoya ungaqhuba nogesi. Lapho i-voltage iphezulu kakhulu, i-current izoqhutshwa emoyeni. Ukushaywa kombani ngesikhathi sokuduma kwezulu kuyisibonelo esivamile sombani oshaya emoyeni. I-voltage yombani iphezulu kakhulu,…

isisekelo se-insulation: kanye ne-nbsp;i-insulation isetshenziswa ezingxenyeni eziphilayo ukuze kunikeze isivikelo esiyisisekelo ngokumelene nokushaqeka kukagesi Njengoba kukhonjisiwe esithombeni esingakwesokunxele ngezansi, isithombe sekhava engezansi yefeni, futhi isithombe esingakwesokudla isithombe esingenayo ikhava engezansi. Isikhumba socingo oluluhlaza nolunsundu ngaphakathi kwentambo yokuhlinzeka esithombeni esilungile singabhekwa njengokwahlukanisa okuyisisekelo. Ngesikhathi esifanayo, izikhumba zocingo ezimhlophe, ezibomvu nezimnyama ekushintsheni okuxhunywe kugobolondo elimnyama nazo zingahlulelwa…
