Yintoni iiyunithi yabathengi?
Yintoni iyunithi yabathengi? Enye indlela eyaziwa ngokuba yibhokisi yefuse, iyunithi yabathengi idlala indima ebalulekileyo kwipropati yakho, inoxanduva lokulawula umbane wekhaya lakho.
Ukuqonda iCandelo laBathengi: Icandelo eliPhambili leNkqubo yoMbane
Igama elithi “ibhokisi yeedrowa” lidla ngokukhankanywa kwihlabathi leenkqubo zombane, kodwa abantu abaninzi basenokungayiqondi ngokupheleleyo intsingiselo kunye nomsebenzi walo.Ibhokisi yeedrowa, ekwaziwa ngokuba yi-switchboard okanye i-fuse box, yinxalenye ebalulekileyo ekufakweni kombane kwiindawo zokuhlala nakwiindawo zorhwebo.Isebenza njengesikhungo esiphambili solawulo nokusasazwa kombane kwisakhiwo sonke, iqinisekisa ukusetyenziswa kombane ngokukhuselekileyo nangokufanelekileyo.
Uyilo oluphambili lweyunithi yokusasazwa kwamandla (i-PDU) kukukhusela iisekethe zombane ngaphakathi kwesakhiwo. Iquka izaphuli zesekethe ezakhelwe ngaphakathi okanye iifusi njengezixhobo zokhuseleko, zithintela ukugqithiswa kakhulu kunye neesekethe ezimfutshane ezinokubangela imililo yombane okanye zonakalise izixhobo. Kwimeko yempazamo, i-PDU iyazicima ngokuzenzekelayo umbane, idlala indima ebalulekileyo ekukhuseleni ubomi kunye nepropathi.
Omnye wemisebenzi ephambili yeyunithi yokusasaza umbane (i-PDU) kukusasaza umbane kwiisekethe nganye ngaphakathi kwesakhiwo.Isekethe nganye inikezelwe kwindawo ethile okanye isixhobo, njengokukhanyisa, ukufudumeza, okanye iindawo zokufaka umbane. Olu hluhlu aluphuculi nje kuphela ukhuseleko kodwa lukwavumela ulawulo olungcono lwemithwalo yamandla. Umzekelo, ukuba isekethe igcwele kakhulu, yisekethe leyo kuphela eya kukhubeka, ngelixa iisekethe eziseleyo ziya kuqhubeka nokusebenza ngendlela eqhelekileyo.
Iinkqubo zokusasazwa kwamandla zanamhlanje zimele uphuculo olukhulu kunezo zemveli. Ukungeniswa kwezixhobo zamandla ezisele (ii-RCD) kutshintshe ukhuseleko lombane. Ii-RCD zenzelwe ukubona ukungalingani kwamandla anokubonisa ingxaki, njengokutshayiswa kombane ngengozi. Nje ukuba zifunyenwe, ii-RCD ziqhawula umbane ngokukhawuleza, nto leyo enciphisa kakhulu umngcipheko wokutshayiswa kombane. Ngenxa yoko, imithetho emininzi yokwakha ngoku ifuna ukufakwa kwee-RCD kwiinkqubo zokusasazwa kombane, ngakumbi kwiindawo ezinomngcipheko ophezulu ezifana namagumbi okuhlambela kunye neekhitshi.
Enye into ebalulekileyo kwi-PDU kukuthobela kwayo imigangatho nemigaqo yombane. Kumazwe amaninzi, ukufakelwa kombane kufuneka kulandele iinkcukacha ezithile ukuqinisekisa ukhuseleko nokuthembeka. Ii-PDU kufuneka zifakwe ngoosombane abafanelekileyo abaqhelene nale migaqo kwaye baqinisekise ukuba ulwakhiwo lwazo luyahlangabezana neemfuno zombane zesakhiwo. Ukuhlolwa rhoqo kunye nokugcinwa kwe-PDU kubalulekile ukuqinisekisa ukusebenza ngokukhuselekileyo okuqhubekayo.
Xa ucinga ngokufaka okanye ukuphucula iyunithi yokuhambisa umbane (i-PDU), kufuneka kuqwalaselwe izinto ezininzi. Ubungakanani beyunithi bufanele buhambelane neemfuno zomthwalo wombane wendlu. Amakhaya amakhulu anezixhobo ezininzi anokufuna i-PDU eqinileyo eneesekethe ezininzi, ngelixa amakhaya amancinci anokufuna iyunithi esisiseko kuphela. Ngaphezu koko, indawo ye-PDU ibalulekile; kufuneka ifikeleleke lula xa ilungiswa kwaye ivalwe ngokukhawuleza.
Ekugqibeleni, i-PDU yinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane, iqinisekisa ukusasazwa kwamandla okukhuselekileyo, okusebenzayo, nokulawulwayo. Ukuqonda umsebenzi wayo kunye nokubaluleka kwayo kunokunceda abanini bezindlu kunye nabaphathi bepropathi ukuba benze izigqibo ezinolwazi malunga nezixhobo zabo zombane. Njengoko iteknoloji iqhubeka ihambela phambili, kulindeleke ukuba ii-PDU zibone ezinye izinto ezintsha, ziphucule indima yazo ekukhuthazeni ukhuseleko lombane kunye nokusebenza kakuhle kubomi bemihla ngemihla. Nokuba wakha ikhaya elitsha okanye uphucula inkqubo yombane ekhoyo, ukuqinisekisa ukuba i-PDU yakho ihlaziyiwe kwaye ihambelana nemigangatho yangoku kubalulekile kukhuseleko kunye nempilo yabo bonke abahlali.
