Isihloko: Indima Ebalulekile Ka-Ama-RCBOekuqinisekiseni ukuphepha kukagesi
ukwethula:
Ama-Residual current breaker (RCBOs) anokuvikelwa kokulayisha ngokweqileyizinto ezibalulekile ezidlala indima ebalulekile ekuvimbeleni izingozi zikagesi nokuqinisekisa ukuphepha kwabantu nempahla. Kulesi sihloko, sizohlola indlela yokusebenza kanye nokubaluleka kwama-RCBO, sihlole imisebenzi yawo, izinzuzo zawo, kanye negalelo lawo elibalulekile ekuphepheni kukagesi.
Funda ngama-RCBO:
Ama-RCBOyimishini yokushintsha kagesi eyenzelwe ukuvikela amasekethe kagesi ezinhlotsheni ezahlukene zamaphutha, okuhlanganisa ukuvuza kanye nokulayisha ngokweqile. Ihlanganisa imisebenzi yedivayisi yamanje esele (i-RCD) kanye ne-i-miniature circuit breaker (MCB), okwenza kube lula futhi kube lula ukusebenza. Ama-RCBO ahlinzeka ngokuvikelwa okuphelele ezingozini zikagesi ngokuhlinzeka ngokuvikelwa kwamanje okusele kanye nokuvikelwa kokulayisha ngokweqile kuyunithi eyodwa.
Isivikelo samanje esisele:
Omunye wemisebenzi eyinhloko ye-I-RCBOiwukuthola nokuphazamisa ukugeleza kwamanje lapho kutholakala ukuvuza emhlabeni. Lokhu kutholwa kwenziwa nge-transformer yamanje ebucayi eqapha njalo ukugeleza kwamanje kusifunda. Uma kutholakala umehluko phakathi kwamanje angenayo kanye nogesi obuyayo (ongathathi hlangothi), i-RCBO izokhubeka, iphazamise amandla kusifunda futhi ivimbele ingozi yokushaqeka kukagesi okuyingozi.
Ukuvikelwa komthwalo oweqile:
Ngaphezu kokuvikelwa kwamanje okusele,I-RCBOfuthi inomsebenzi wokuvikela ukunqwabelana ngokweqile. Ibona ukugeleza kwamandla kagesi ngokweqile kusekethe (ngokuvamile okubangelwa yithuluzi likagesi elinephutha noma isekethe elifushane) bese iphendula ngokuvula isekethe ukuvimbela ukushisa ngokweqile kanye nengozi yomlilo engaba khona. Ngokukhawulela ukugeleza kwamandla kagesi kumazinga aphephile, ama-RCBO asiza ekugcineni ubuqotho besistimu kagesi, evikela imishini nalabo abayisebenzisayo.
Izinzuzo eziyingqayizivele ze-RCBO:
1. Ukulula nokusebenza kahle kwesikhala:
Ukuhlanganisa ukuvikelwa kwamandla kagesi asele kanye nokusetshenziswa ngokweqile kwe-overload kuyunithi eyodwa kwenza kube lula kakhulu ukufakwa kukagesi. Ngokungafani nezinhlelo zendabuko ezidinga ama-RCD nama-MCB ahlukene, ama-RCBO avumela ukusethwa okuncane kakhulu, okunciphisa isikhala esidingekayo sama-switchboard nama-switchboard. Lokhu kuhlanganiswa akugcini nje ngokuthuthukisa ukulula, kodwa futhi kwenza ukulungiswa nokuxazulula izinkinga kube lula.
2. Ukuphepha okuthuthukisiwe:
Ama-RCBO anikeza izinga eliphezulu lokuvikela kunezinye ezizimele. Lawa madivayisi ahlanganisa ukuvuza komhlaba kanye nokuvikelwa kokuthwala ngokweqile ukuqinisekisa ukuvikelwa okuphelele ezingozini zikagesi. Amandla okukhubeka ngokusheshaI-RCBOkusiza ukunciphisa ubude kanye nobukhulu bemiphumela yokushaqeka.
3. Ukuguquguquka:
Ukuguquguquka kanye nokuzivumelanisa nezimo kweI-RCBOinegalelo ekusetshenzisweni kwayo kabanzi ezinhlotsheni ezahlukene zokusebenza. Kusukela ezakhiweni zokuhlala nezebhizinisi kuya ezindaweni zezimboni, ama-RCBO ayizingxenye ezibalulekile zezinhlelo zokuphepha kagesi. Avikela amaphutha wamandla asele kanye nogesi oweqile, okwenza afaneleke ezinhlobonhlobo eziningi zokufakwa kukagesi, okuhlanganisa amasekethe anika amandla izibani, izinto zikagesi kanye nemishini.
Ekuphetheni:
Enkathini lapho ugesi usuyingxenye ebalulekile yempilo yethu, ukuphepha kukagesi kubaluleke kakhulu.Ama-RCBOukuhlinzeka ngendlela ethembekile yokuvikela amaphutha wamanje asele kanye nokulayisha ngokweqile, ukuvimbela izingozi zikagesi ezingabangela ukulimala komuntu, ukulimala kwempahla noma ngisho nokufa. Ngokusebenza kwayo okuphelele, ukulula kanye nokuguquguquka, ama-RCBO afakazelwe ukuthi ayingxenye ebalulekile ezinhlelweni zikagesi kanye nokuphepha okubalulekile ezindaweni zokuhlala nezentengiselwano. Ngokuqaphela ukubaluleka kwama-RCBO nokuwafaka ekufakweni kukagesi, singaqinisekisa ikusasa eliphephile neliphephile kubo bonke.
