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…
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…
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…
We are discussing here the second structure of the PTC heating element, PTC heating element structure please refer to the explanation of its definition. How is the creepage distance of the functional insulation at the location of the red circle in Figure 1 determined? We all know that NOTE 1 of TABLE 18 section has…
Isigaba somthetho 8.1.1 sisho ukuthi uphenyo kufanele lusetshenziswe lapho into esetshenziswayo “isetshenziswa okuvamile”, kuyilapho isigatshana 8.1.5 sihlolwa ngaphambi kokufakwa. Imikhiqizo efana nalena, elethwa ngezingxenye ezimbalwa, ngokuvamile idinga ukufakwa endaweni. “Phila kanye ne-nbsp;izingxenye kanye ne-nbsp;ye kanye ne-nbsp;eyakhelwe ngaphakathi kanye ne-nbsp;imishini, kanye ne-nbsp;i-fixed ne-nbsp;imishini kanye ne-nbsp; kanye ne-nbsp;imishini kanye ne-nbsp;ilethiwe kanye ne-nbsp;ngaphakathi kanye ne-nbsp;hlukanisa futhi nbsp;amayunithi, kanye…
8.1.5 Live parts of built-in appliances, fixed appliances, and appliances delivered in separate units shall be protected by at least basic insulation before installation or assembly. Compliance is checked by inspection and the test in 8.1.1.Why is this requirement in place? I believe there are three types of hazards that require protection. The first is…
