Indlela Yokukhetha Idivayisi Efanele Yokukhiya I-Circuit Breaker

Indlela Yokukhetha Idivayisi Efanele Yokukhiya I-Circuit Breaker
Ake ngikutshele ngesigameko esenzeka ngokuphindaphindiwe efektri: Ngaphambi kokulungisa ngogesi, othile wayesusa inkinobho ye-circuit breaker ekhabhinethi yokusabalalisa ayiyise endaweni ethi “OFF”, alengise ibhodi, ecabanga ukuthi lokhu kuphephile. Kodwa-ke, ithimba eliseduze, lingazi ukuthi othile ulungisa, labuya lamane lavula i-circuit breaker – imishini yaqala ngokuzumayo, futhi abasebenzi bokulungisa bacishe baba nengozi.
Inhloso ye-Circuit Breaker Lockout ukushintsha isimo kusuka kokuthi “kucatshangwa ukuthi kuvaliwe” siye kokuthi “akekho ongakuvula”. Kodwa-ke, inkinga ukuthi ama-circuit breaker afika ngezindlela eziningi nobukhulu obuhlukahlukene, futhi amadivayisi okukhiya nawo ahlukene abe izinhlobo eziningi. Lesi sihloko sikusiza ukuthi ucacise ukucabanga kwakho ngaphambi kokuthenga, ukuze ungagcini uthenga okuthile bese uthola ukuthi ngeke kufakwe kamuva.
Okokuqala, qiniseka ukuthi uyayiqonda i-circuit breaker.
Ngaphambi kokuthenga ilokhi, qiniseka ukuthi uyazi ukuthi ubhekene nohlobo luni lwe-circuit breaker. Ngoba ama-circuit breaker ahlukene anezindlela zokukhiya ezihluke ngokuphelele.
I-Miniature circuit breaker (MCB). Uhlobo oluvame kakhulu olutholakala emabhokisini okusabalalisa, olunezimbobo ezimnyama ububanzi bomunwe, zihlelwe ngemigqa. Lolu uhlobo olulula kakhulu ukulukhiya futhi lunenani elikhulu kakhulu lezingidi ezihambisanayo.
I-Frame circuit breaker (MCCB). Inkulu kune-MCB, inesibambo esibanzi nesibanzi kanye nomthamo wamandla aphezulu. Ivame ukusetshenziswa ekhabhinethini yokusabalalisa eyinhloko ye-workshop noma isekethe yokunikezwa kwamandla yemishini eyodwa enkulu. Ilokhi kufanele ifane ncamashi nosayizi wesibambo.
I-Frame circuit breaker (ACB). Uhlobo olukhulu kunawo wonke, oluyisisekelo samakamelo okusabalalisa ezimbonini. Isibambo sikhulu impela, kanti ezinye zazo azilona uhlobo lwe-lever kodwa uhlobo lwe-rotary handle. Indlela yokukhiya ihluke ngokuphelele ezinhlotsheni ezimbili zangaphambilini.
I-Rotary handle circuit breaker. Akuyona i-toggle switch, kodwa i-round rotary switch engasetshenziswa ngokhiye noma nge-handle. Indlela yokukhiya iwukuvimba indlela ejikelezayo.
I-circuit breaker yenkinobho yokusunduza. Eminye imishini emidala isebenzisa uhlobo lwenkinobho yokusunduza. Ukuyicindezela phansi KUVALIWE, kanti ukuyikhipha KUVALIWE. Lokhu kudinga ukukhiya kohlobo lwesembozo.
Isiphakamiso sokuqala: Yiya ngaphambili kwekhabhinethi yokusabalalisa bese uthatha izithombe zohlobo kanye nomodeli wohlobo ngalunye lwe-circuit breaker. Thatha ngokusobala ukuma, ububanzi besibambo, kanye nesikhala esiseceleni kwaso. Bese ubonisa umhlinzeki izithombe ukuze kuxhunyaniswe. Lokhu kuthembeke ngokuphindwe kayikhulu kunokuchaza “cishe ububanzi obungaka” ngocingo.
Izinhlobo eziningana ezijwayelekile zezikhiye ze-circuit breaker
1. Uhlobo lokungena / Uhlobo lokubopha - Uhlobo olulula kakhulu
Lolu hlobo lokukhiya luboshelwa ngqo esivinjeni se-circuit breaker. Uma ivaliwe, kufakwa iphini lokukhiya ngembobo yokukhiya ukuze iqiniswe. Ukufakwa akudingi amathuluzi futhi kungaqedwa ngemizuzwana embalwa nje.
Isimiso saso silula impela: Uma i-lever isibanjiwe, i-lever ayikwazi ukunyakaza. Uma ikhululwa, iyabhajwa, ithembele endaweni efile yomshini.
Izinto ezisebenzayo: Ama-miniature circuit breaker ajwayelekile anobubanzi obujwayelekile (ama-MCB), uma nje ububanzi be-lever bungama-8-12mm.
Yiziphi imikhawulo? Uma usebenza ngezibambo ezibanzi kakhulu noma ezincane kakhulu, azikwazi ukubanjwa ngokuphephile. Futhi, kulezo zimo lapho ama-circuit breaker amaningi ebekwa eceleni futhi kungekho ndawo eyanele yokusebenza eduze, ama-clamp awakwazi ukufakwa.
2. Uhlobo lokungena/lokuphotha – Kwabaphuli besekethe abafakwe ephanelini
Amanye ama-circuit breaker anembobo encane eyindilinga eduze kwe-toggle lever, eyenzelwe ngqo ukukhiya. Faka iphini elincane kulo mbobo bese uliqinisa ngengidi, bese isibambo sizokhiywa.
Izinto ezisebenzayo: Ama-circuit breaker abunjwe ngepulasitiki ane-built-in locking mechanism (MCCB), kanye nama-MCB athile asezingeni lezimboni.
Izinzuzo: Uma isifakiwe, iqinile kakhulu futhi cishe ngeke ikhishwe. Okubi: Uma kungekho mgodi omncane kangaka obekelwe iphaneli yakho ye-circuit breaker, ngeke ibe usizo.
3. I-Handle Lock Ejikelezayo – Ilungele Ukushintsha Okujikelezayo
Isakhiwo sesibambo esijikelezayo sihlukile kwesesikhiya sohlobo lwe-lever. Isikhiya se-lever asikwazi ukufakwa nhlobo. Isikhiya sesibambo esijikelezayo sivame ukuba nesembozo noma indandatho yokubopha, ebekwa nxazonke kwesibambo ukuze sivimbele ukuthi sijikeleze.
Ukugxila Kokuthenga: Ububanzi bangaphandle kanye nesimo sesibambo. Ezinye ziyindilinga, ezinye ziyisicaba, kanti ezinye zinezimbobo zokhiye. Umehluko wamamilimitha ambalwa nje ngobukhulu uzovimbela ukuthi singangeni. Sebenzisa i-caliper ukuze ulinganise; ungathembeli ekulinganisweni okubonakalayo.
4. Okufakiwe / Uhlobo lwebhokisi - Ukukhiya ngaphandle komugqa wonke
Uma imigqa eminingana yama-circuit breaker kukhabhinethi yokusabalalisa idinga ukukhiywa ngasikhathi sinye, ukuwakhiya ngamunye ngamunye ngeke kusebenze kahle. Ilokhi evalekile iyisembozo sepulasitiki esibonakalayo esimboza umugqa wonke noma iqembu lama-circuit breaker. Iboshelwa ngelokhi ngemva kokuboshwa ngokuphephile.
Izinzuzo: Ikhiya ingxenye ngayinye ngesikhathi esisodwa. Izinyathelo Zokuqapha: Ifanele amabhokisi okusabalalisa lapho ama-circuit breaker ahlelwe kahle futhi anesikhala esijwayelekile. Uma ama-circuit breaker ebhokisini lokusabalalisa egobile noma isikhala singalingani, isembozo singase singavaleki kahle.
5. Uhlobo lwe-Universal / Donsa-rod – Inketho yokugcina
Amanye ama-circuit breaker anezimo ezingavamile kangangokuthi akukho zikhiye ezijwayelekile ezifanelana. Ezimweni ezinjalo, i-"pull-rod type" noma i-"universal type" Circuit Breaker Lockout ingasetshenziswa - empeleni, iyindlela yokukhiya elungisekayo. Ngokuqinisa izikulufo noma ukudonsa intambo, iswishi ingakhiywa endaweni ethi OFF, bese ivalwa nge-padlock.
Uma ngikhuluma iqiniso, ukuzinza kwalolu hlobo lokukhiya akukuhle njengokwalabo abakhethekile. Kungasebenza, kodwa uma unenketho engcono, kungcono ukhethe ekhethekile. Uhlobo olujwayelekile luyindlela yokugcina hhayi ukukhetha kokuqala.
