Isihloko: Ukuqonda Ukubaluleka KweI-Earth Leakage Circuit Breakers
ethula
Ezweni lanamuhla lapho ukuphepha kukagesi kubaluleke kakhulu,ama-circuit breaker asele (RCCBs)idlala indima ebalulekile ekuvikeleni ukuphepha kwempilo yomuntu kanye nempahla.Nakuba abaningi bengase bangalazi leli gama,Ama-RCCBsziyingxenye ebalulekile yanoma yiluphi uhlelo lukagesi.Lesi sihloko sihlose ukucacisa ukubaluleka kwama-circuit breaker amanje, umsebenzi wabo kanye nezinzuzo zabo ekuvikeleni ukufakwa kukagesi.
Isigaba 1: Yini i-umhlaba ukuvuza circuit breaker?
I-Residual current circuit breaker, ejwayele ukubizwa ngokuthi i-I-RCCB, iyisisetshenziswa sikagesi esiklanyelwe ukuvikela abantu ngabanye kanye nokufakwa kukagesi ezingozini zomlilo ezibangelwa ukuvuza kukagesi.Kalula nje, iI-RCCBiqapha i-current in a circuit futhi ihambe isekethe uma ithola ukungalingani kwamanje.Lokhu kungalingani kungase kubangelwe ukuvuza kwemisinga, amaphutha e-insulation, noma ukuthintana ngokuqondile namakhondaktha aphilayo.
Isigaba 2: Kwenziwa kanjani i-umsebenzi we-earth leakage circuit breaker?
Izinqamuli zesekethe zamanje ezivuzayo zifakwe iziguquli zamanje ezizwelayo ezihlala zilinganisa amandla amanje ngamakhondaktha aphilayo naphakathi nendawo.Noma kunini lapho kunomehluko phakathi kwe-input current kanye ne-return current, kukhombisa ukuvuza noma iphutha.II-RCCBithola lokhu kungqubuzana futhi igibe ngokushesha isekethe, inqamule amandla ukuvimbela umonakalo owengeziwe.
Isigaba sesithathu: izinzuzo zokuvuza kwama-circuit breakers
Ukufaka i-earth leakage circuit breaker kunezinzuzo eziningi mayelana nokuphepha nokuvikela.Okokuqala, banganciphisa kakhulu ingozi yokushaqeka kukagesi ngokuthola ukungalingani okuncane kumjikelezo nokuphazamisa amandla ngesikhathi.Okwesibili,Ama-RCCBszibalulekile ekuvikeleni imililo ebangelwa amaphutha kagesi, njengoba zisabela ngokushesha emisinga kagesi engavamile, zinciphisa amandla okushisa ngokweqile kanye ne-arcing.
Ngaphezu kwalokho, ama-circuit breaker avuzayo anganqamula ngokushesha ukunikezwa kwamandla uma kwenzeka ukuvuza noma ukwehluleka, ukunikeza ukuvikeleka okwengeziwe kwemishini nezinto zikagesi.Ngokwenza kanjalo, okokusebenza okubalulekile kungavikelwa ngokuvikela ekulimaleni okungaba khona, okuholela ekongeni kwezindleko nempilo ende.
Isigaba 4: Izinhlobo zama-circuit breaker avuzayo
Kunezinhlobo ezimbili eziyinhloko zeAma-RCCBs: Uhlobo lwe-AC kanye Nohlobo A. Ama-RCCB ohlobo lwe-AC avame ukusetshenziswa ezindaweni zokuhlala ukuze anikeze ukuvikeleka kuma-sinusoidal alternating currents.Lawa ma-RCCB alungele ukuvikeleka emithonjeni evamile yokuvuza njengokungaxhunywanga kahle, izintambo ezilimele, nokwehluleka kwezisetshenziswa.
Uhlobo A ama-RCCB, ngakolunye uhlangothi, athuthuke kakhulu futhi ahlinzeka ngokuvikeleka okwengeziwe ngokufaka i-alternating current and pulsating direct current (DC).Lawa ma-RCCB avame ukufakwa ezinhlelweni zokusebenza ezichwepheshile ezifana nezibhedlela, iziza zezimboni nalapho kusetshenziswa khona okokusebenza okubucayi kagesi.Uhlobo A lwe-RCCBs luqinisekisa ukuvikeleka okugcwele kumaphutha e-AC ne-DC ngaphandle kwanoma yisiphi isikhala sokufaka engozini.
Isigaba 5: Ukubaluleka kokuvamileI-RCCBukuhlolwa nokugcinwa
Nakuba ama-circuit breaker amanje abalulekile ngokungangabazeki ekuphepheni kukagesi, kubalulekile futhi ukuqonda ukubaluleka kokuhlolwa nokugcinwa njalo.Njenganoma yimuphi omunye umshini kagesi,Ama-RCCBsubudala ngokuhamba kwesikhathi, ukunciphisa ukusebenza kwabo noma ukwehluleka.Ngakho-ke, ukuhlolwa nokugcinwa njalo kufanele kuhlelwe ukuze kuqinisekiswe ukuthiI-RCCBisezingeni eliphezulu futhi ivimbela noma yiziphi izingozi ezingaba khona zikagesi.
Isigaba 6: Isiphetho
Ekuphetheni, ama-circuit breaker amanje asele ayingxenye ebalulekile yezinhlelo zikagesi zanamuhla, ezihlinzeka ngokuvikeleka okubalulekile ngokumelene nokushaqeka kukagesi kanye nezingozi zomlilo.I-RCCB ingakwazi ukubona ukungalingani kwamanje futhi iphazamise ukujikeleza ngesikhathi, okungathuthukisa kakhulu ukuphepha kokusetshenziswa kukagesi futhi kuvikele impilo nempahla.Ngokutshala imali kuma-RCCB ekhwalithi ephezulu, ukukhetha uhlobo olulungile kuhlelo lokusebenza ngalunye, nokwenza ukuhlola nokunakekela okuvamile, sonke singazakhela indawo kagesi ephephile ngokwethu nezizukulwane ezizayo.
