Isihloko: Ukuqonda Ukubaluleka Kwe-Ama-Miniature Circuit Breaker (ama-MCB)ukuphepha kukagesi
ukwethula:
Ezweni lanamuhla lanamuhla, ugesi udlala indima ebalulekile empilweni yethu yansuku zonke. Kodwa-ke, ungadala izingozi eziningi uma ungaphathwa kahle. Ngakho-ke, kubalulekile ukuthatha izinyathelo zokuphepha ezisebenzayo ukuvikela abantu nemishini ezingozini zikagesi. Enye yezinto ezibalulekile ukuqinisekisa ukuphepha kukagesi yi-i-miniature circuit breaker (MCB)Kulesi sihloko sebhulogi, sibheka ngokujulile umhlaba we-Ama-MCB, ukubaluleka kwazo, nokuthi zinegalelo kanjani ekuphepheni kukagesi.
1. Kuyinii-miniature circuit breaker (MCB)?
A i-miniature circuit breaker, okuvame ukubizwa ngokuthiI-MCB, iyithuluzi likagesi elenzelwe ukuvikela isekethe kanye nemishini yalo exhunywe kuyo ekushiseni ngokweqile. Ukushisisa ngokweqile kungenzeka ngenxa yesekethe emfushane noma ukushisisa ngokweqile okugeleza ngesekethe. I-MCB iqapha ukushisisa okuqhubekayo ngesekethe futhi ikhubaza noma inqamule ngokuzenzakalelayo ukunikezwa kwamandla uma ithola ukushisisa ngokweqile.
2. Kunganiama-circuit breaker amancanekubalulekile ekuphepheni kukagesi?
2.1 Ukuvimbela imililo kagesi:
Imililo kagesi ibangela ingxenye enkulu yemililo yomhlaba wonke. Amasekethe kagesi anephutha noma agcwele ngokweqile avame ukubangela le mililo.I-MCBkuyindlela yokuqala yokuzivikela ezigamekweni ezinjalo. Uma ugesi ugeleza kakhulu esikethini, i-miniature circuit breaker iyakhubeka ngokushesha, inqamule isekethe futhi inqamule ugesi. Lokhu kusabela okusheshayo kuvimbela izintambo ekushiseni ngokweqile futhi okungenzeka ziqale umlilo.
2.2 Ukuvikelwa kwemishini kagesi:
Amandla kagesi amaningi angalimaza imishini kagesi ebucayi, okuholela ekulungisweni okubizayo noma ekushintshweni.Ama-MCBvikela la madivayisi ngokunqamula ugesi uma kwenzeka ugesi udlula kakhulu. Ngokusebenza njengabalawuli besekethe, bavikela imishini emonakalweni obizayo obangelwa ukushintshashintsha kwamandla kagesi noma amasekethe amafushane.
2.3 Ukuphepha komuntu siqu okuthuthukisiwe:
Ukushaqeka kukagesi kuyingozi enkulu empilweni yabantu. Ama-MCB adlala indima ebalulekile ekunciphiseni ingozi yezehlakalo ezinjalo ngokuvimbela ukugeleza kwamandla kagesi ngokweqile kumasekethe nakuma-kagesi. Ukukhubeka kwesekethe kungavimbela izingozi ezingaba khona futhi kuvikele abantu ekushaqekeni kukagesi okuyingozi.
3. Izici kanye nezinzuzo zama-miniature circuit breakers:
3.1 Izilinganiso zamanje:
Ama-MCBzitholakala ngezilinganiso zamanje ezahlukahlukene futhi zingasetshenziswa ezinhlotsheni ezahlukene zamasekethe nezinhlelo zokusebenza. Kodwa-ke, isilinganiso samanje esifanele kumele sikhethwe ngokuya ngomthwalo wesekethe ukuqinisekisa ukuvikelwa nokusebenza okuhle kakhulu.
3.2 Indlela ephumelelayo yokukhubeka:
I-MCB inendlela yokushintshashintsha kokushisa kanye nendlela yokushintshashintsha komoya i-magnetic. Indlela yokushintshashintsha kokushisa ivikela ezimweni zokulayisha ngokweqile, izimo lapho ugesi ogeleza khona isikhathi eside. Indlela yokushintshashintsha komoya ibona amasekethe amafushane ahilela ugesi ophakeme isikhathi esifushane.
3.3 Ukusetha kabusha okusheshayo nokulula:
Ngemva kokuba i-MCB ikhubekile ngenxa yesigameko noma iphutha elingaphezu kwamandla, ingasethwa kabusha kalula ngokuhambisa iswishi yokushintsha i-toggle emuva endaweni ethi ON. Lesi sici siqeda isidingo sokushintsha ama-fuse ngesandla futhi sinikeza indlela elula yokubuyisela amandla ngokushesha.
4. Ukufakwa nokugcinwa kwama-miniature circuit breakers:
4.1 Ukufakwa kobungcweti:
Ukuqinisekisa ukusebenza kahle kanye nokuphepha okuphelele kukagesi kwe-I-MCB, ukufakwa kwayo kufanele kwenziwe njalo nguchwepheshe kagesi oqeqeshiwe. Banolwazi oludingekayo lokuhlola ngokunembile izidingo zomthwalo wesekethe nokukhetha nokufaka i-MCB efanele.
4.2 Ukuhlolwa nokuhlolwa okuvamile:
Ukuhlolwa nokugcinwa njalo kwe-ama-circuit breaker amancaneKubalulekile ekuboneni izinkinga ezingaba khona, ukuqinisekisa ukuthembeka kwazo kanye nokugcina ukusebenza kwazo okuphezulu. Inqubo yokuhlola kumele ilandelwe njalo ukuqinisekisa ukukhubeka kwe-MCB ngaphansi kwezimo zamandla aphezulu.
Ekuphetheni:
Ama-Miniature circuit breaker (ama-MCB)ziyizingxenye ezibalulekile zezinhlelo zikagesi ezihlinzeka ngokuvikelwa okubalulekile ezingozini zikagesi. Ngokubona nokuvala ugesi ngokushesha uma kwenzeka ugesi udlula ngokweqile, ama-miniature circuit breakers avimbela imililo kagesi, avikele imishini, futhi avikele abantu ekushaqekeni kukagesi okuyingozi. Ukulula kokusebenza, isici sokusetha kabusha okusheshayo, kanye nokutholakala kwezilinganiso zamanje ezahlukene kwenza ama-MCB abe yisinqumo esihle kakhulu sokugcina ukuphepha kukagesi ezindaweni ezahlukahlukene zokuhlala, zezentengiselwano, nezezimboni. Kubalulekile ukubeka phambili ukufakwa, ukuhlolwa kanye nokugcinwa kwe-Ama-MCBukuqinisekisa ukusebenza kwazo okuhle kakhulu nokudala indawo kagesi ephephile kuwo wonke umuntu.
