Umhlahlandlela Womsebenzi Nokufakwa Kwebhokisi Lokusabalalisa

UkuqondaIyunithi Yabathengi: Ingxenye Eyinhloko Ohlelweni Lukagesi

Igama elithi “iyunithi yokudonsa amandla” livame ukukhulunywa ngalo emhlabeni wezinhlelo zikagesi, kodwa abantu abaningi bangase bangaqondi ngokugcwele ukuthi lisho ukuthini noma ukuthi lisebenza kanjani. Iyunithi yokudonsa amandla, eyaziwa nangokuthi iphaneli yokusabalalisa noma ibhokisi le-fuse, iyisici esibalulekile ekufakweni kukagesi kwezindlu nezentengiselwano. Isebenza njengesikhungo sokusabalalisa, iqinisekisa ukuthi ugesi ulethwa ngokuphephile nangokufanele kumasekethe ngamanye kulo lonke isakhiwo.

Iyini iyunithi yokusebenzisa?

Enhliziyweni yayo, iyunithi yokusabalalisa amandla iyindawo ebiyelwe egcina ama-circuit breaker, ama-fuse, namanye amadivayisi okuvikela. Umsebenzi wayo oyinhloko ukusabalalisa amandla avela emthonjeni wamandla oyinhloko aye kumasekethe ahlukene futhi inikeze ukuvikelwa kokulayisha ngokweqile kanye ne-short-circuit. Iyunithi yokusabalalisa amandla ivame ukuba seduze nendawo lapho umthombo wamandla ungena khona esakhiweni ukuze kube lula ukulungisa nokuhlola.

IZINGXENYE ZAMAYUNITHI OKUSEBENZISA

Iyunithi yabathengi ejwayelekile iqukethe izingxenye eziningana ezibalulekile:

1. Iswishi eyinhloko: Lena yiswishi eyinhloko elawula ukunikezwa kukagesi esakhiweni sonke. Ivumela umsebenzisi ukuthi anqamule ukunikezwa kukagesi ngenxa yokuphepha ngesikhathi sokulungiswa noma isimo esiphuthumayo.

2. Ama-circuit breaker: Lawa madivayisi anqamula ngokuzenzakalelayo ukuhamba kukagesi uma kwenzeka ukugcwala ngokweqile noma i-short circuit, okuvimbela izingozi ezingaba khona njengemililo kagesi. I-circuit ngayinye esakhiweni ixhunywe ku-circuit breaker ethile ukuze iyinqamule uma kwenzeka iphutha.

3. I-RCD (Idivayisi Yamanje Esele): I-RCD iyithuluzi lokuphepha elinqamula ugesi uma libona ukungalingani kwamandla kagesi, okungase kubonise iphutha noma ukuvuza. Lokhu kubaluleke kakhulu ukuvimbela ukushaqeka kukagesi.

4. Ibha Yebhasi: Lena yinto ehambisa ugesi esetshenziselwa ukusabalalisa ugesi kuma-circuit breaker ahlukahlukene ngaphakathi kweyunithi kagesi. Isebenza njengendawo ephakathi yokusabalalisa ugesi.

5. Ukuvala: Iyunithi yamandla ifakwe endaweni evalekile evikelayo, evame ukwenziwa ngensimbi noma ngepulasitiki. Indawo evalekile ayivikeli nje kuphela izingxenye zangaphakathi, kodwa futhi ivimbela ukuthintana ngengozi nezingxenye eziphilayo, ngaleyo ndlela iqinisekise ukuphepha.

Ukubaluleka Kwamayunithi Abathengi

Iyunithi yokusabalalisa ugesi idlala indima ebalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kwezinhlelo zikagesi. Ivumela ukuphathwa okungcono kokunikezwa kukagesi ezindaweni ezahlukene zesakhiwo ngokuhlinzeka ngendawo yokusabalalisa ephakathi. Lokhu kubaluleke kakhulu ezindaweni zokuhlala zesimanje nezebhizinisi lapho kusetshenziswa khona amadivayisi kagesi amaningi kanye nezinto zikagesi ngasikhathi sinye.

Ngaphezu kwalokho, kufakwa ama-circuit breaker kanye namadivayisi wamanje asele (ama-RCD) ngaphakathi kwe-PDU ukuze kuncishiswe izingozi zikagesi ukuze kuqinisekiswe ukuphepha okwengeziwe. Ukugcinwa nokuhlolwa njalo kwe-PDU kubalulekile ukuqinisekisa ukuthi zonke izingxenye zisebenza kahle nokuthi uhlelo luhambisana nezindinganiso zikagesi zamanje.

Thuthukisa iyunithi yakho yabathengi

Njengoba ubuchwepheshe buthuthuka futhi isidingo sikagesi sikhula, abanikazi bezindlu namabhizinisi amaningi bangase bathole ukuthi amayunithi abo okusabalalisa ugesi akhona awasakwazi ukuqhubeka. Ukuthuthukela kuyunithi yokusabalalisa ugesi yesimanje kunganikeza izinzuzo eziningi, okuhlanganisa ukuphepha okuthuthukisiwe, umthamo wesekethe owandisiwe, kanye nokusebenza kahle kwamandla okukhulu. Kunconywa ukuthi uthintane nochwepheshe kagesi ofanelekayo ukuze ahlole uhlelo lwakho lwamanje futhi anqume ukuthi ukuthuthukiswa kuyadingeka yini.

Ngokufigqiwe

Ngamafuphi, i-PDU iyisici esibalulekile sanoma yiluphi uhlelo lukagesi futhi iyinhliziyo yokusatshalaliswa kwamandla ngaphakathi kwesakhiwo. Ukuqonda izingxenye zayo nemisebenzi kubalulekile kunoma ubani ohilelekile ekufakweni noma ekulungisweni kukagesi. Ngokuphatha kahle i-PDU nokubeka phambili ukuphepha nokusebenza kahle, singaqinisekisa ukuthi uhlelo lukagesi lusebenza kahle nangokuphepha. Kungakhathaliseki ukuthi ungumnikazi wendlu, umnikazi webhizinisi, noma uchwepheshe kagesi, ukuqaphela ukubaluleka kwe-PDU kuyisihluthulelo sokugcina indawo kagesi ephephile nesebenza kahle.
