Byforest August 26, 2024August 31, 2024

ukwakhiwa kwesigaba III: ingxenye yesisetshenziswa esivikela ukushaqeka kukagesi sincike ekuphepheni kwamandla kagesi aphansi kakhulu nalapho ama-voltage aphezulu kunalawo okuphepha kwamandla kagesi aphansi kakhulu angakhiqizi.Qaphela ukwahlukanisa okuyisisekelo kungase kudingeke ngaphezu kokuphakelwa kwa-SELV. Bheka ku-8.1.4.QAPHELA 2 Uma ingxenye eyinhloko yomshini isebenza e-SELV futhi ilethwa kanye neyunithi yokuphakelwa kukagesi ekhiphekayo khona-ke le ngxenye eyinhloko yale ngxenye eyinhloko ibhekwa…

Isigaba sesi-3 – Iqondwa kanjani incazelo “yokwakhiwa kwekilasi II”
Byforest August 17, 2024August 31, 2024

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 yekilasi I”
Byforest August 14, 2024September 5, 2024

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…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“functional insulation”
Byforest August 7, 2024August 31, 2024

i-functional insulation: ukwahlukanisa phakathi kwezingxenye ze-conductive zamandla ahlukene okudingeka kuphela ekusebenzeni kahle komshini. I-insulation esebenzayo isethwe ngenxa yezidingo zokusebenza zomshini. Emikhiqizweni kagesi, kufanele kube nezingxenye ze-conductive ezinamandla ahlukene (ama-voltage ahlukene). Uma i-voltage yawo wonke ama-conductor anamandla emkhiqizweni iyafana, into esetshenziswayo ayikwazi ukusebenza. Khona-ke, kukhona ukufakwa okusebenzayo phakathi kwezingxenye ezahlukene ze-conductive. Uma sicabanga ukuthi i-voltage elinganiselwe…
