UkuqondaIyunithi yabathengi: Inxalenye Ebalulekileyo Kwinkqubo Yombane
Igama elithi “iyunithi yokutsala umbane” lidla ngokukhankanywa kwihlabathi leenkqubo zombane, kodwa abantu abaninzi basenokungayiqondi ngokupheleleyo into eliyithethayo okanye indlela elisebenza ngayo. Iyunithi yokutsala umbane, eyaziwa ngokuba yiphaneli yokusasaza okanye ibhokisi yefuse, licandelo elibalulekileyo ekufakweni kombane kwiindawo zokuhlala nakwiindawo zorhwebo. Lisebenza njengeziko lokusasaza umbane, liqinisekisa ukuba umbane uhanjiswa ngokukhuselekileyo nangokufanelekileyo kwiisekethe ngazinye kulo lonke isakhiwo.
Yintoni iyunithi yokusetyenziswa?
Embindini wayo, iyunithi yokusasaza umbane yindawo ebiyelweyo egcina ii-circuit breakers, ii-fuses, kunye nezinye izixhobo zokukhusela. Umsebenzi wayo oyintloko kukusasaza umbane ukusuka kumthombo oyintloko wamandla ukuya kwiisekethe ezahlukeneyo kunye nokubonelela ngokhuseleko lokugqithisa kunye nolwe-short-circuit. Iyunithi yokusasaza umbane idla ngokuba kufutshane nendawo apho umthombo wamandla ungena khona kwisakhiwo ukuze kube lula ukugcinwa nokuhlolwa.
IZINTO EZISETYENZISWAYO
Iyunithi eqhelekileyo yabathengi inamacandelo aliqela abalulekileyo:
1. Iswitshi ephambili: Le yiswitshi ephambili elawula umbane kwisakhiwo sonke. Ivumela umsebenzisi ukuba aqhawule umbane ngenxa yokhuseleko ngexesha lokulungiswa okanye imeko kaxakeka.
2. Iziphuli-mbane zesekethe: Ezi zixhobo zithintela ngokuzenzekelayo ukuhamba kombane xa kukho i-overload okanye i-short circuit, zithintela iingozi ezinokubakho ezifana nemililo yombane. Isekethe nganye kwisakhiwo iqhagamshelwe kwi-circuit breaker ethile ukuze iyiqhawule xa kukho impazamo.
3. I-RCD (Isixhobo sangoku esisele): I-RCD sisixhobo sokhuseleko esinqumla umbane ukuba sibona ukungalingani kwamandla, okunokubonisa impazamo okanye ukuvuza. Oku kubaluleke kakhulu ukuthintela ukutshayiswa ngumbane.
4. Ibha yeBhasi: Le yimpahla eqhuba umbane esetyenziselwa ukusasaza umbane kwii-circuit breakers ezahlukeneyo ngaphakathi kweyunithi yombane. Isebenza njengendawo ephambili yokusasaza umbane.
5. Ukuvalwa: Iyunithi yamandla ifakwe kwindawo ekhuselayo, edla ngokwenziwa ngentsimbi okanye ngeplastiki. Indawo evaliweyo ayikhuseli nje kuphela izinto zangaphakathi, kodwa ikwathintela ukudibana ngengozi nezinto eziphilayo, ngaloo ndlela iqinisekisa ukhuseleko.
Ukubaluleka kweeYunithi zaBathengi
Iyunithi yokusasaza umbane idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko nokusebenza kakuhle kweenkqubo zombane. Ivumela ulawulo olungcono lokunikezelwa kombane kwiindawo ezahlukeneyo zesakhiwo ngokubonelela ngendawo yokusasaza ephakathi. Oku kubaluleke kakhulu kwiindawo zokuhlala zanamhlanje nezorhwebo apho kusetyenziswa izixhobo zombane ezininzi kunye nezixhobo ngaxeshanye.
Ukongeza, ii-circuit breakers kunye nezixhobo zamandla ombane ezisele (ii-RCD) zifakelwe ngaphakathi kwi-PDU ukunciphisa iingozi zombane ukuze kubekho ukhuseleko olongezelelekileyo. Ukugcinwa rhoqo kunye nokuhlolwa kwe-PDU kubalulekile ukuqinisekisa ukuba zonke izinto zisebenza ngokufanelekileyo kwaye inkqubo iyahambelana nemigangatho yamandla ombane yangoku.
Phucula iyunithi yakho yabathengi
Njengoko ubuchwepheshe buhambela phambili kwaye imfuno yombane ikhula, abaninimzi abaninzi kunye namashishini banokufumanisa ukuba iiyunithi zabo zokusasaza umbane ezikhoyo azisakwazi ukuqhubeka. Ukuphucula ukuya kwiyunithi yokusasaza umbane yanamhlanje kunokubonelela ngeenzuzo ezininzi, kubandakanya ukhuseleko oluphuculweyo, amandla ombane anyukileyo, kunye nokusebenza kakuhle kwamandla. Kucetyiswa ukuba udibane nosombane ofanelekileyo ukuze uvavanye inkqubo yakho yangoku kwaye umisele ukuba uphuculo luyimfuneko na.
Isishwankathelo
Ngamafutshane, i-PDU yinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane kwaye yintliziyo yokusasazwa kwamandla kwisakhiwo. Ukuqonda izinto zayo kunye nemisebenzi yayo kubalulekile kuye nabani na obandakanyekayo ekufakweni okanye ekugcinweni kombane. Ngokulawula ngokufanelekileyo i-PDU kunye nokubeka phambili ukhuseleko kunye nokusebenza kakuhle, sinokuqinisekisa ukuba inkqubo yombane isebenza kakuhle nangokukhuselekileyo. Nokuba ungumnikazi wendlu, umnini weshishini, okanye unjingalwazi wombane, ukuqonda ukubaluleka kwe-PDU kubalulekile ekugcineni imeko-bume yombane ekhuselekileyo nesebenzayo.
