Isihloko: Ukuqonda Ukubaluleka Kwe-Ama-Residual Current Breakers anesivikelo sokulayisha ngokweqile (I-RCBO)
ukwethula:
A i-residual current circuit breaker (RCBO) enesivikelo sokulayisha ngokweqilekuyingxenye ebalulekile yesistimu kagesi. Badlala indima ebalulekile ekuvikeleni ukufakwa kukagesi kanye nabantu abakusebenzisayo.I-RCBOihlanganisa imisebenzi emibili ebalulekile: ukuvikelwa kwamanje okusele kanye nokuvikelwa kokudlula ngokweqile. Kulesi sihloko sebhulogi, sizohlola ukuthi kungani ama-RCBO ebalulekile, lokho akwenzayo, kanye nezinzuzo azinikezayo. Ake sihlole umhlaba wama-RCBO nokuthi kungani eyingxenye ebalulekile yokuphepha kukagesi.
1. KuyiniI-RCBO?
I-RCBO, nomaI-Residual Current Breaker ene-Overload Protection, iyidivayisi esebenza ngezindlela eziningi eyenzelwe ukuvikela amaphutha kagesi. Ihlanganisa imisebenzi ye-standard circuit breaker kanye nedivayisi yamanje eseleyo (i-RCD) ibe yiyunithi eyodwa. Inhloso eyinhloko yaleI-RCBOiwukuthola ukungalingani kukagesi okubangelwa ukuvuza kwamanzi futhi kuhlinzeke ngokuvikelwa kokudlula ngokweqile noma kwe-short circuit.
2. Ama-RCBO asebenza kanjani?
I-RCBO iqapha njalo ugesi ogeleza ngesekethe. Ilinganisa ugesi ongenayo nophumayo ngesekethe bese iwuqhathanisa ukuqinisekisa ukuthi akukho ukungalingani okungajwayelekile. Uma kutholwa ukungalingani, okubonisa ugesi ovuzayo, i-RCBO izokhubeka ngokushesha, inqamule ugesi kuma-mains. Lesi senzo sesikhashana sisiza ukuvimbela ukushaqeka kukagesi noma izingozi zomlilo.
Ngaphezu kwalokho,Ama-RCBOhlinzeka ngokuvikelwa kokulayisha ngokweqile ngokuqapha umthwalo ophelele kusekethe. Uma ugesi udlula isilinganiso esinqunyiwe isikhathi eside, i-RCBO iyakhubeka, inqamule ugesi ukuze kuvinjelwe umonakalo ohlelweni lukagesi kanye nezingxenye zalo.
3. Ukubaluleka kwe-RCBO ekuphepheni kukagesi:
Ama-RCBO abalulekile ekuphepheni kukagesi ngezizathu eziningana. Okokuqala, avimbela izingozi ezingaba yingozi ezihlobene nokushaqeka kukagesi. Ngokuqapha imisinga evuzayo nokusabela ngokushesha kuyo, ama-RCBO anciphisa amathuba okushaqeka kukagesi futhi ahlinzeke ngendawo ephephile kubahlali.
Ngaphezu kwalokho, ama-RCBO adlala indima ebalulekile ekuvimbeleni imililo kagesi ebangelwa ama-short circuits noma ukulayisha ngokweqile.I-RCBOinqamula ugesi ngokushesha lapho kuvela izimo ezingavamile, okungavimbela izintambo nezinto zikagesi ekushiseni ngokweqile futhi kunciphise ingozi yomlilo.
4. Izinzuzo ze-RCBO:
Ukufaka ama-RCBO ohlelweni lukagesi kunezinzuzo eziningi. Okokuqala, ama-RCBO ahlinzeka ngokuvikelwa kwesekethe ngayinye, okukuvumela ukuthi ubone futhi uhlukanise isekethe ethile enephutha ngaphandle kokuthinta okunye ukufakwa. Lokhu kuvikelwa okungaphelele kuvumela ukuxazulula izinkinga nokulungisa okusheshayo, kunciphisa isikhathi sokungasebenzi futhi kunciphisa ingozi yokulimaza amanye amasekethe.
Okwesibili, ama-RCBO ayaguquguquka futhi aguquguqukayo. Isilinganiso samanje esilungisekayo seI-RCBOivumela ukwenza ngokwezifiso izidingo ezithile zesekethe ngayinye. Lokhu kuvumelana nezimo kuqinisekisa ukuvikeleka okuhle ngenkathi kuhambisana nemithwalo eminingi kagesi esakhiweni noma esikhungweni.
Ngaphezu kwalokho, ukuvikelwa kwamanje okusele kanye nokuvikelwa kokudlula ngokweqile kuhlanganiswa kudivayisi eyodwa, kususa isidingo sama-RCD ahlukene kanye nama-circuit breaker, konga isikhala, kunciphisa izindleko zokufaka kanye nokwenza lula ukulungiswa.
5. I-RCBOukufakwa nokugcinwa:
Ukufaka i-RCBO kudinga ubuchwepheshe ukuqinisekisa usayizi ofanele, izintambo kanye nokuhlolwa. Kubalulekile ukubonisana nochwepheshe kagesi oqeqeshiwe ongahlola umthwalo othile kagesi, akhethe i-RCBO efanele, futhi awuhlanganise kahle ohlelweni.
Ukuhlolwa nokugcinwa njalo kudlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kwe-RCBO yakho. Lokhu kuhlanganisa ukuhlolwa njalo kwemishini (kufaka phakathi izikhathi zohambo) ukuqinisekisa ukuthi ihlangabezana nezindinganiso zokuphepha. Ngaphezu kwalokho, ukuhlolwa okubonakalayo kungasiza ekutholeni noma yiziphi izimpawu zomonakalo noma izinkinga ezingabeka engcupheni ukuthembeka kwe-RCBO.
Ekuphetheni:
Ama-Residual current breaker (RCBOs) anokuvikelwa kokulayisha ngokweqileziyizingxenye ezibalulekile zezinhlelo zikagesi zanamuhla. Zinikeza indlela ethembekile nephumelelayo yokuvikela ukwehluleka kukagesi, zihlinzeka ngokuvikelwa ekushayweni ugesi kanye nokuvimbela izingozi zomlilo ezingaba khona. Ukuhlanganiswa kokuvikelwa kwamanje okusele kanye nokuvikelwa kokudlula ngokweqile kudivayisi eyodwa kwenza i-RCBO ibe ukukhetha okuguquguqukayo kokufakwa kukagesi. Ngokukhetha kahle nokufaka ama-RCBO nokwenza ukulungiswa njalo, singaqinisekisa ukuphepha futhi sandise impilo yesistimu yakho kagesi. Qiniseka ukuthi uthintana nochwepheshe kagesi ofanelekayo ukuze anqume i-RCBO efanele izidingo zakho ezithile futhi ujabulele ukuthula kwengqondo okuza nohlelo lokuvikela ugesi oluthembekile.
