Kuyiniiyunithi yabathengi?
Iyini iyunithi yabathengi? Eyaziwa nangokuthi ibhokisi le-fuse, iyunithi yabathengi idlala indima ebalulekile endaweni yakho, inesibopho sokulawula ukuphakelwa kukagesi ekhaya lakho.
Ukuqonda Iyunithi Yabathengi: Ingxenye Eyinhloko Yesistimu Kagesi
Igama elithi “ibhokisi lamadrowa” livame ukukhulunywa ngalo emhlabeni wezinhlelo zikagesi, kodwa abantu abaningi bangase bangayiqondi ngokugcwele incazelo yalo kanye nomsebenzi walo.Ibhokisi lamadrowa, elaziwa nangokuthi i-switchboard noma ibhokisi le-fuse, liyingxenye ebalulekile ekufakweni kukagesi ezindaweni zokuhlala nezokuhweba.Isebenza njengesikhungo esiyinhloko sokuphathwa nokusabalalisa ugesi esakhiweni sonke, iqinisekisa ukusetshenziswa kukagesi okuphephile nokuphumelelayo.
Umklamo oyinhloko weyunithi yokusabalalisa amandla (i-PDU) ukuvikela amasekethe kagesi ngaphakathi kwesakhiwo. Ifaka ama-circuit breaker noma ama-fuse akhelwe ngaphakathi njengamadivayisi okuphepha, okuvimbela ukugcwala ngokweqile kanye namasekethe amafushane angabangela imililo kagesi noma alimaze imishini. Uma kwenzeka iphutha, i-PDU ivala ugesi ngokuzenzakalelayo, idlala indima ebalulekile ekuvikeleni impilo kanye nempahla.
Omunye wemisebenzi eyinhloko yeyunithi yokusabalalisa amandla (i-PDU) ukusabalalisa amandla okusetshenziswa kwezinsiza kumasekethe ngamanye ngaphakathi kwesakhiwo.Isekethe ngayinye inikezelwe endaweni noma kudivayisi ethile, njengokukhanyisa, ukushisa, noma izindawo zokufaka ugesi. Lokhu kuhlukaniswa akugcini nje ngokuthuthukisa ukuphepha kodwa futhi kuvumela ukuphathwa okungcono kwemithwalo yamandla. Isibonelo, uma isekethe igcwele ngokweqile, yileyo sekethe kuphela ezokhubeka, kuyilapho isekethe esele izoqhubeka nokusebenza ngokujwayelekile.
Izinhlelo zokusatshalaliswa kwamandla zesimanje zimelela ukuthuthuka okukhulu kunezo zendabuko. Ukwethulwa kwamadivayisi wamanje asele (ama-RCD) kushintshe ukuphepha kukagesi. Ama-RCD aklanyelwe ukubona ukungalingani kwamanje okungase kubonise iphutha, njengokushaqeka kukagesi ngengozi. Uma esetholakele, ama-RCD anqamula ngokushesha ukuphakelwa kukagesi, okunciphisa kakhulu ingozi yokushaqeka kukagesi. Ngenxa yalokho, imithetho eminingi yokwakha manje idinga ukufakwa kwama-RCD ezinhlelweni zokusatshalaliswa kukagesi, ikakhulukazi ezindaweni ezinobungozi obukhulu njengezindlu zangasese namakhishi.
Esinye isici esibalulekile se-PDU ukuhambisana kwayo nezindinganiso kanye nemithethonqubo kagesi. Emazweni amaningi, ukufakwa kukagesi kumele kuhambisane nemininingwane ethile ukuqinisekisa ukuphepha nokuthembeka. Ama-PDU kumele afakwe ngochwepheshe bakagesi abaqeqeshiwe abajwayelene nale mithethonqubo futhi baqinisekise ukuthi ukwakheka kwawo kuhlangabezana nezidingo zikagesi zesakhiwo. Ukuhlolwa njalo nokugcinwa kwe-PDU nakho kubalulekile ukuqinisekisa ukusebenza okuphephile okuqhubekayo.
Uma ucabanga ukufaka noma ukuthuthukisa iyunithi yokusabalalisa amandla (i-PDU), kufanele kucatshangelwe izici eziningana. Usayizi weyunithi kufanele uhambisane nezidingo zomthwalo kagesi wendlu. Izindlu ezinkulu ezinemishini eminingi zingadinga i-PDU eqinile kakhulu enezisekelo eziningi, kuyilapho izindlu ezincane zingadinga iyunithi eyisisekelo kuphela. Ngaphezu kwalokho, indawo ye-PDU ibalulekile; kufanele ifinyeleleke kalula ukuze ilungiswe futhi ivalwe ngokushesha.
Ekugcineni, i-PDU iyisici esibalulekile sanoma yiluphi uhlelo lukagesi, okuqinisekisa ukusatshalaliswa kwamandla okuphephile, okusebenzayo, nokulawulwayo. Ukuqonda umsebenzi wayo kanye nokubaluleka kwayo kungasiza abanikazi bezindlu kanye nabaphathi bezindawo ukuthi benze izinqumo ezinolwazi mayelana nemishini yabo kagesi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ama-PDU kulindeleke ukuthi abone ezinye izinto ezintsha, athuthukise indima yawo ekukhuthazeni ukuphepha nokusebenza kahle kukagesi empilweni yansuku zonke. Kungakhathaliseki ukuthi wakha ikhaya elisha noma uthuthukisa uhlelo lukagesi olukhona, ukuqinisekisa ukuthi i-PDU yakho ibuyekeziwe futhi ihambisana nezindinganiso zamanje kubalulekile ekuphepheni nasempilweni yabo bonke abahlala kuyo.
