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…
QAPHELA izinto zikagesi zeSigaba 0 zinendawo ebiyelwe yezinto ezivalelayo ezingase zakhe ingxenye noma yonke into eyisisekelo, noma indawo ebiyelwe yensimbi ehlukaniswa nezingxenye ezibukhoma ngokufakwa okufanele. Uma into esetshenziswayo evalekile yezinto ezivikelayo inenhlinzeko yezingxenye zangaphakathi ze- earthing, ibhekwa njengento esetshenziswayo yekilasi I noma isisetshenziswa sekilasi 0I.Lolu hlobo lukagesi alunaso isisetshenziswa somhlaba esivikelayo, futhi ngesikhathi esifanayo, ungqimba…
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…
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…
functional insulation as well as other insulation exists on circuit boards. Typically, the surface environment of a circuit board is determined to be either Pollution degree 3 or pollution degree 2.If the circuit board is mounted in an electrical box and sealed with a solid sealant, the sealing will look as follows: What should be…
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…
