Isigaba sesi-3 – Iqondwa kanjani incazelo yegama elithi “clearance”

Byforest

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,…

Isigaba sesi-3 – Iqondwa kanjani incazelo “yokwakhiwa kwekilasi II”

Ukugcizelelwa lapha kuyingxenye yokwakhiwa kwento esebenza ngogesi, engahlangabezana nezidingo zokufakwa okuphindwe kabili noma ukufakwa okuqinisiwe. Ngakho-ke, into esetshenziswayo Yekilasi I futhi izoqukatha ukwakhiwa Kwekilasi II .Isibonelo: Ihhavini eboniswe emfanekisweni ongezansi isebenzisa igobolondo lensimbi kanye nephini lokushintsha lepulasitiki. Uma umsebenzisi ethinta inkinobho yokushintsha, ifindo lenziwe ngezinto ezivikelayo futhi alikwazi ukumiswa. Ukuvikela ngokumelene nokushaqeka kukagesi kungancika kuphela…

Isigaba sesi-3 – Iqondwa kanjani incazelo “yensiza yeklasi II”

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…

umshini kagesi wesigaba I: umshini lapho ukuvikeleka kokushaqeka kukagesi kungancikile ekufakeni izinto eziyisisekelo kuphela kodwa okuhlanganisa nesexwayiso sokuphepha esengeziwe, ngokuthi izingxenye ezifinyelelekayo eziqhutshwayo zixhunywe ku-conductor yomhlaba ovikelayo kuzintambo ezingaguquki zokufakwa ngaleyo ndlela. ukuthi izingxenye ezifinyelelekayo azikwazi ukuba bukhoma uma kwenzeka ukwehluleka kokufakwa okuyisisekeloQAPHELA Lokhu kunikezwa kuhlanganisa i-conductor yomhlaba evikelayo entanjeni yokuhlinzeka. Isibonelo: Ngokuyisisekelo, izinto ezisetshenziswayo…
