Ukuqonda Ama-Mcb Circuit Breakers: Umhlahlandlela Ophelele
Ezweni lobunjiniyela kagesi nokuphepha, ama-miniature circuit breaker (ama-MCB) adlala indima ebalulekile ekuvikeleni ama-circuit kagesi ekugcwaleni ngokweqile kanye nama-short circuits. Lawa madivayisi abalulekile kokubili ezinhlelweni zikagesi zasemakhaya nezebhizinisi, avikela izinto zikagesi kanye nezintambo emonakalweni ongaba khona obangelwa ugesi ongaphezulu.
Kuyini i-Mcb circuit breaker?
I-MCB circuit breaker iyiswishi ezenzakalelayo ephazamisa ukuhamba kwamandla kagesi kusekethe lapho ibona isimo esingavamile, njengokugcwala ngokweqile noma i-short circuit. Ngokungafani nama-fuse endabuko, okumele ashintshwe ngemva kokuba evunguzile, ama-MCB circuit breaker angasethwa kabusha ngemva kokuba ekhubekile, okwenza kube inketho elula nephumelelayo yokuvikela isekethe.
Isebenza kanjani i-Mcb circuit breaker?
Ukusebenza kwama-Mcb circuit breakers kusekelwe ezindleleni ezimbili eziyinhloko: ukushisa kanye ne-magnetic.
1. Indlela yokushisa:Le ngxenye isabela ezimweni zokulayisha ngokweqile. Lapho ugesi ogeleza ngesekethe udlula umthamo olinganisiwe we-circuit breaker, ukushisa okukhiqizwayo kubangela ukuthi ugesi we-bimetallic ngaphakathi kwe-circuit breaker ugobe. Uma ukugoba sekufinyelele ezingeni elithile, ugesi we-bimetallic uqala indlela yokwephula ugesi, uvale ugesi.
2. Indlela Kamagnetic: Le ndlela iklanyelwe ukuphendula kuma-short circuits. Uma kwenzeka i-short circuit, ugesi ukhuphuka ngokushesha, udala insimu enamandla yamagnetic edonsa i-lever, okwenza i-circuit breaker ikhubeke cishe ngokushesha. Lokhu kusabela okusheshayo kubalulekile ekuvimbeleni ukulimala kwezingxenye zikagesi nokunciphisa ingozi yomlilo.
Uhlobo lwe-Mcb circuit breaker
Ama-circuit breaker e-Mcb atholakala ngezinhlobo eziningana, ngayinye yenzelwe injongo ethile:
Uhlobo B: Ngezinhlelo zokusebenza zokuhlala, lolu hlobo lwe-circuit breaker luhamba ngokuphindwe kathathu kuya kahlanu kunogesi olinganisiwe. Lufaneleka kahle kuma-circuit anemithwalo yokumelana, njengokukhanyisa nokushisa.
Uhlobo C: Lolu hlobo lwenzelwe ukusetshenziswa kwezentengiselwano nezimboni, olune-current current ephindwe ka-5 kuya ku-10 kunolaka olulinganisiwe. Lufanelekela amasekethe anemithwalo yokungenisa, njengezinjini nama-transformer.
Uhlobo DLolu hlobo lusetshenziswa ezisetshenziswayo ezinamaza okungena aphezulu, njengezinjini ezinkulu kanye nama-transformer. Ihamba ngokuphindwe kayishumi kuya kwangama-20 kunolamandla olinganiselwe.
Izinzuzo zokusebenzisa ama-circuit breaker e-Mcb
1. Ukuphepha: Ama-circuit breaker e-Mcb ahlinzeka ngendlela ethembekile yokuvikela ama-circuit ekugcwaleni ngokweqile kanye nama-short circuit, okunciphisa kakhulu ingozi yemililo kagesi kanye nomonakalo wemishini.
2. UkululaNgokungafani nama-fuse adinga ukushintshwa ngemva kokuvunguza, ama-Mcb circuit breaker angasethwa kabusha kalula, okuyinto elula ukuyisebenzisa.
3. Umklamo Omncane: Ama-circuit breaker e-MCB mancane futhi mancane kakhulu kunamadivayisi okuvikela i-circuit avamile, okuvumela ukusetshenziswa kahle kwesikhala kumaphaneli kagesi.
4. Izindleko Ezingabizi: Nakuba ukutshalwa kwezimali kokuqala kungaba phezulu kune-fuse, ukonga kwesikhathi eside kusukela ekulimaleni kwemishini okuncishisiwe kanye nokulula kokusetha kabusha kwenza ama-Mcb circuit breaker abe yisinqumo esingabizi kakhulu.
Ukufakwa Nokunakekelwa
Ukufakwa kwe-circuit breaker kufanele kwenziwe njalo nguchwepheshe kagesi oqeqeshiwe ukuqinisekisa ukuthi kulandelwa imithetho kagesi yendawo kanye nezindinganiso zokuphepha. Kunconywa nokuhlolwa kokugcinwa njalo ukuqinisekisa ukuthi ama-circuit breaker asebenza kahle kanye nokuhlonza noma yiziphi izinkinga ezingaba khona ngaphambi kokuba zibe zimbi kakhulu.
Uyini umehluko phakathi kwama-MCB nama-MCCB breakers?
Ama-MCB: Ngokuvamile asetshenziswa ezinhlelweni zokusebenza zezentengiselwano nezezimboni ezinama-voltage aphansi, ngokuvamile i-120V, i-240V noma i-480Y VAC, kanye ne-VDC efika ku-1000. Ama-MCCB: Angasetshenziswa kokubili ezinhlelweni zokusebenza ezinama-voltage aphansi kanye naphezulu, ngezilinganiso ezivame ukufika ku-600V noma ku-690V, kanti amanye amamodeli alinganiswa ngama-voltage aphezulu.
Ngokufigqiwe
Kalula nje, ama-circuit breaker e-MCB ayizingxenye ezibalulekile ezinhlelweni zikagesi zesimanje, ahlinzeka ngokuphepha, ukulula, kanye nokusebenza kahle. Ukuqonda izimiso zawo zokusebenza, izinhlobo, kanye nezinzuzo kungasiza abanikazi bezindlu namabhizinisi ukuthi benze izinqumo ezinolwazi mayelana nezidingo zabo zokuvikela ugesi. Njengoba ubuchwepheshe buqhubeka nokukhula, ama-circuit breaker e-MCB azoqhubeka nokuba yitshe lesisekelo lokuphepha kukagesi, aqinisekise ukuthi amakhaya ethu nezindawo zokusebenza zivikelwe ezingozini zikagesi.
