>>> Isishwankathelo seMveliso
Ikhabhathi yokusasazwa kwamandla eXL ithatha amacandelo amatsha ayilwe ekhaya. Iqokobhe layo lenziwe ngeepleyiti zentsimbi ezigobileyo, ezinesakhiwo esibambeneyo, ukugcinwa okufanelekileyo, kunye nokudibanisa okuguquguqukayo kwezicwangciso zesekethe. Ukongeza kwi-air circuit breakers kunye ne-fuses yokukhusela isiphaluka, ikhabhinethi yokusabalalisa iyakwazi ukuxhotyiswa kunye neefowuni kunye ne-thermal relays. Umnyango wangaphambili webhokisi unokuxhotyiswa ngamaqhosha okusebenza kunye nezibane zesalathisi. Xa ukutshintshwa kommese kufunwa, isibambo saso sokusebenza sifakwe kwindawo ephezulu yekholamu ekunene phambi kwebhokisi, engasetyenziselwa ukutshintsha izixhobo zombane. Ikhabhinethi inomnyango ngaphambili, kwaye xa umnyango uvuliwe, zonke izixhobo ezingaphakathi kwekhabhinethi zibonakaliswe, ziququzelele ukugcinwa nokulungiswa. Umnyango wangaphambili uvula umnyango osekhohlo ovulekileyo, oxhotyiswe ngezixhobo zokulinganisa ezifana ne-voltmeters kunye ne-ammeters, kunye nokusebenza kombane kunye nezixhobo zomqondiso. Isixhobo sokuhambisa amandla esinesakhiwo esilula, ukusebenza okuthembekileyo, kunye neendleko eziphantsi. Ilungele ukusetyenziswa kwizakhiwo zoshishino kunye nezoluntu kwi-AC frequency 50Hz, i-voltage 500V kunye ne-IT engaphantsi kweenkqubo ze-IT, iinkqubo ze-TN-C, iinkqubo ze-TT (ezaziwa ngaphambili njengezigaba ezintathu zocingo, izigaba ezintathu zeenkqubo zombane ezine-four) zamandla kunye nokusabalalisa ukukhanya. Ikwafaneleka ukwenza iikhabhathi ezahlukeneyo zokuqalisa iimoto, ezibandakanya iikhabhathi ezigcweleyo zokuqalisa i-voltage, iikhabhathi ezipheleleyo zolawulo lwedijithali ezithambileyo, iikhabhathi zokuqalisa i-auto-transformer, iikhabhathi zokuqalisa i-star-delta, iikhabhathi zokuqalisa ngesantya semoto ezininzi, njl.
Le mveliso ihambelana nemigangatho esebenzayo: I-IEC60439-1 "i-Low-voltage Switchgear kunye ne-Controlgear Assemblies" kunye ne-GB / T 7251.12 "I-Low-voltage Switchgear kunye ne-Controlgear Assemblies - Icandelo 1: Ii-Assemblies ezivavanyiweyo zohlobo kunye ne-Partial Type-Ted Tested". Inqanaba lokhuseleko yi-IP30.
