Nhlamuselo ya Xikombiso
Swihlawulekiso
2. 1. Switirhisiwa swa ku lahlekeriwa ka le hansi na dizayini ya xivumbeko leyi hlayisaka eneji,ku hunguta swinene ku lahlekeriwa hi ku pfumala ndzhwalo/short-circuit na ku ndlandlamuxa vukorhokeri bya matirhiselo ya eneji.
2. 1. Hi dizayini leyi pfaleriweke hi ku helela na ku pfaleriwa, ku fikelela xiyimo xa lP68 xa nsirhelelo wa ndzhongho/mati/ntshuri, leswi hlanganisiweke na ti fins leti ti titimelaka ta ku tirha loku tiyeke eka tindhawu to tika.
2. 1. Ku vekiwa ehansi ka misava swi hunguta swinene mpfumawulo ( electromagnetic radiation.Switirhisiwa swa le henhla swi hlanganisa swinavetiso mabokisi ya rivoni lama nga na mintirho yo hangalasa matimba, ku ringanisela vuxongi na ku tirha.
2. 1. Miri lowukulu lowu lahliweke hiku hetiseka wu herisa ndzhawu yale henhla ka misava ntirho, .swinene eka tisenthara ta le madorobeni na tindhawu leti nga na ndhawu yo tala.
2. 1. Henhla ka LV switchgear leyi hlanganisiweke na misavaswihlawulekisi swa scape yi hunguta makhombo loko yi ri karhi yi ndlandlamuxa vuxongi bya le madorobeni.
Range ya ku tirhisiwa
Swi lulamerile eka swiyimo swo hambana swa ku vekiwa ka gezi leswi rharhanganeke, ku fana na makamara ya ku hangalasiwa ka gezi ehansi ka misava eka tindhawu ta le xikarhi ka madoroba, tindhawu ta le hansi eka tindhawu ta mabindzu, tindhawu to hangalasa gezi ehansi ka misava eka tithanele ta mimovha, na switirhisiwa swo seketela ku hangalasiwa ka gezi ehandle, tindhawu leti nga na swifaniso swo saseka, switichi swa switimela swa le hansi ka misava, tindhawu to paka ehansi ka misava, na swin’wana na swin’wana Swiendlakalo leswi hi ntolovelo swi na swilaveko swa le henhla swa mpfumawulo wa matirhelo ya switirhisiwa, ku tekiwa ka ndhawu na nsirhelelo wa swikepe.
