We know that clause 29.3.2 and clause 21.2 are two separate clauses and they are not very much related, which means that the product being assessed needs to fulfill both clauses if applicable.A reinforced insulation system consisting of three separate layers of insulating material or what could be considered a double insulation system, Each layer…
safety extra-low voltage: voltage not exceeding 42 V between conductors and between conductors and earth, the no-load voltage not exceeding 50 V When safety extra-low voltage is obtained from the supply mains, it is to be through a safety isolating transformer or a convertor with separate windings, the insulation of which complies with double insulation…
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…
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…
ukufakwa okuqinisiwe: ukufakwa okukodwa okufakwe ezingxenyeni ezibukhoma, okunikeza izinga elithile lokuvikela ekushayweni kukagesi okulingana nokufakwa kabili ngaphansi kwezimo ezishiwo kuleli zinga.Njengoba kukhonjisiwe ezithombeni ezimbili ezingezansi, isithombe esingakwesokunxele yisithombe sangemuva sesiqandisi. Ibhodi lesifunda ngaphakathi lingabonakala nge-grille yensimbi esithombeni kwesokunxele, futhi isithombe sangaphakathi isithombe esifanele. Kunezingxenye ezibukhoma ku-PCB, futhi umsebenzisi angakwazi ukuthinta i-grille. Umoya ophakathi kwegebe le-grille…
double insulation: isistimu yokuhlukanisa ehlanganisa kokubili ukufakwa okuyisisekelo kanye nokufakwa okungeziwe Incazelo iwukwenza lula kuphela incazelo yokugquma okuyisisekelo kanye nokwahlukanisa okungeziwe ezingeni, kusetshenziswa igama elilodwa ukuchaza amagama amabili. Njengoba kukhonjisiwe emfanekisweni ongezansi, intambo yokunikezela inezingqimba ezimbili zokuvala, umgodla wocingo ongaphakathi kanye nomgodla wocingo omnyama ongaphandle, ochazwa ngokuthi ukufakwa kabili. Njengoba kukhonjisiwe ezithombeni ezimbili ezilandelayo(ifeni), umgodla…
i-supplementary insulation: i-insulation ezimele isetshenziswa ngaphezu kokufakwa okuyisisekelo, ukuze kuhlinzekwe ukuvikeleka ekushaqekeni kukagesi uma kwenzeka ukwehluleka kokufakwa kwesisekelo I-insulation engaphandle kwe-insulation eyisisekelo futhi ezimele ku-insulation eyisisekelo, futhi ngokuvamile ifinyeleleka kumsebenzisi. I-supplementary insulation, njengoba negama lisho, ingeziwe, futhi ibhekisela ekufakeni okungeziwe ekufakeni okuyisisekelo. Lokhu kuhilela isimiso esiyisisekelo saleli zinga, okungukuthi isimiso sokuvikela okuphindwe kabili. Kunoma iyiphi…
Kukhona inothi kuthebula 17 kanye nethebula 18 njengokuthi “Kuma-voltage okusebenza kanye ne-gt; 10 V kanye ≤ 630 V, uma i-voltage ingacaciswanga kuthebula, amanani amabanga ahamba phambili angatholwa ngokufaka phakathi.”. Uma i-voltage yokusebenza ingelona inani elisohlwini lwetafula, ngakho-ke ngokuvamile sidinga ukubala ukuze sithole inani elilinganiselwe, ukuze kube lula, ngilungise ithebula le-excel, abahloli bangabuza ngokuqondile ithebula ukuze…
