Iiyunithi yabathengiyenye yezona zinto zibalulekileyo kulo naluphi na ukufakelwa kombane kwisakhiwo sokuhlala okanye sorhwebo. Igcina iswitshi ephambili, iifusi kunye nee-circuit breakers kwaye ilawula ukusasazwa kombane kuyo yonke indawo. Kweli nqaku, siza kujonga nzulu ukubaluleka kweeyunithi zabathengi kwaye sixoxe ngemisebenzi kunye neempawu zazo.
Eyona njongo iphambili yeyunithi yababhalisileyo kukukhusela isekethe ekugqithiseni kakhulu nakwisekethe emfutshane. Isebenza njengomqobo wokhuseleko phakathi kwamandla angenayo kwigridi kunye nezixhobo ezahlukeneyo ngaphakathi kwesakhiwo. Ngaphandle kwezixhobo zombane, umngcipheko weengozi zombane ezifana nomlilo kunye nokutshayiswa kombane uyanda kakhulu.
Izixhobo zabathengi ziza ngeentlobo ezahlukeneyo kunye nobukhulu obuhlukeneyo ngokuxhomekeke kwiimfuno ezithile zokufakelwa kombane. Uhlobo oluqhelekileyo lubizwa ngokuba yibhokisi yefuse yendabuko, apho uthotho lweefuse lukhusela isekethe nganye. Nangona kunjalo, izixhobo zabathengi zanamhlanje ngoku zixhotyiswe kakhulu ngee-circuit breakers, ezisebenza kakuhle kwaye zibonelela ngokhuseleko olungcono.
Omnye wemisebenzi ephambili yeyunithi yababhalisileyo yiswitshi enkulu. Le switshi ikuvumela ukuba ucime umbane kuyo yonke indawo xa kukho imeko engxamisekileyo okanye xa kufuneka umsebenzi wokulungisa. Iswitshi ephambili kufuneka ifikeleleke lula, ngoko ke ihlala ikwindawo ebonakalayo nefikelelekayo lula, njengakwindawo yokungena okanye kwigumbi lombane.
Ngaphakathi kwiyunithi yabathengi, kukho iisekethe ezahlukeneyo ezisasaza umbane kwiindawo ezahlukeneyo zesakhiwo. Ezi sekethe zikhuselwe zii-fuses okanye ii-circuit breakers ezenzelwe ukuvula isekethe ngokuzenzekelayo xa kukho i-overload okanye i-short circuit. Olu phawu luthintela ukonakala kwezixhobo kunye nezixhobo ezidityaniswe nesekethe, luqinisekisa ukhuseleko lwabangaphakathi.
Olunye uphawu olubalulekileyo lwezixhobo zanamhlanje zabathengi sisixhobo samandla asele (RCD). I-RCD sisixhobo sokhuseleko esibona ngokukhawuleza naluphi na ukungalingani kumbane wombane, njengaxa umntu echukumisa ucingo oluphilayo ngengozi. Emva koko siya kuyicima ngokuzenzekelayo umbane, sithintele ukutshayiswa kombane kwaye sinokusindisa ubomi. Ii-RCD ziye zaba yimfuneko kwiindawo ezininzi zokufakelwa kombane, ngakumbi kwiindawo ezinamanzi afana neekhitshi kunye namagumbi okuhlambela.
Kwiminyaka yakutshanje, izixhobo zabathengi nazo ziye zatshintsha zaza zaquka ezinye izinto, ezinje ngokukhusela ukugqobhoza.Izixhobo zokukhusela ukuqubha (ii-SPD)nceda ekukhuseleni izixhobo kwii-voltage spikes ezibangelwa kukubethwa ngumbane okanye ukunyuka kwamandla. Ngokufaka ii-SPD kwizixhobo zabathengi, ungakhusela izixhobo zakho ze-elektroniki ezixabisekileyo ezifana noomabonwakude, iikhompyutha kunye nezixhobo zasekhaya kumonakalo onokwenzeka.
Ngamafutshane, izixhobo zombane ziyinxalenye ebalulekileyo yalo naluphi na ukufakelwa kombane. Ziqinisekisa ukusasazwa kombane ngokukhuselekileyo kulo lonke isakhiwo, zikhusela iisekethe kunye nabantu ngaphakathi kwesakhiwo. Xa ukhetha isixhobo somthengi, kubalulekile ukukhetha esihlangabezana neemfuno ezithile zenkqubo yakho yombane kwaye sihambelana nemigangatho yokhuseleko efanelekileyo. Ukugcinwa rhoqo kunye nokuhlolwa rhoqo kweeyunithi zabathengi nako kubalulekile ukuqinisekisa ukusebenza kwazo okuqhubekayo kunye nokhuseleko.
