Isicelo

I-CJMM1 series molded case circuit breaker (ebizwa ngokuthi i-circuit breaker) iyasebenza kwi-AC 50/60HZ power distribution network circuit ene-insulation voltage elinganisiwe engu-800V, i-operation voltage elinganisiwe engu-690V kanye ne-operation current elinganisiwe kusukela ku-10A kuya ku-630A, isetshenziselwa ukusabalalisa amandla nokuvimbela imishini yesekethe kanye neyokuphakelwa kwamandla ekulimaleni ngenxa yokugcwala ngokweqile, i-short circuit, i-under voltage kanye nezinye izinkinga, isetshenziselwa futhi ukuqala kaningi kwemoto kanye nokugcwala ngokweqile, i-short circuit kanye nokuvikelwa kwe-voltage. Le circuit breaker inezinzuzo zevolumu encane, amandla aphezulu okuphuka, i-short arcing (noma i-noarcing) njll., ingafakelwa izesekeli ezifana nokuxhumana kwe-alamu, ukukhululwa kwe-shunt, ukuxhumana okusizayo njll., ingumkhiqizo ofanele umsebenzisi. I-residual current current breaker ingafakwa ngokuqondile (ukufakwa okuqondile) noma ifakwe ngokuvundlile (ukufakwa okuvundlile). Umkhiqizo uhambisana namazinga e-IEC60947-2 kanye ne-Gb140482

Kuyini i-MCCB?

Ama-Molded case circuit breakers amadivayisi okuvikela kagesi aklanyelwe ukuvikela isekethe kagesi kusuka kumandla kagesi amaningi. Lo mandla kagesi amaningi angabangelwa ukugcwala ngokweqile noma isekethe esifushane. Ama-molded case circuit breakers angasetshenziswa ku-voltage ehlukahlukene kanye nama-frequency anomkhawulo ophansi nophezulu wezilungiselelo zokuhamba ezilungisekayo. Ngaphezu kwezindlela zokukhubeka, ama-MCCB angasetshenziswa futhi njengokushintshana kokuxhuma ngesandla uma kwenzeka isimo esiphuthumayo noma imisebenzi yokulungisa. Ama-MCCB ajwayelekile futhi ahlolwe ukugcwala kwamandla kagesi, ukukhuphuka kwamandla kagesi, kanye nokuvikelwa kwamaphutha ukuqinisekisa ukusebenza okuphephile kuzo zonke izindawo kanye nezinhlelo zokusebenza. Asebenza kahle njengokushintshana kabusha kwesekethe kagesi ukuze anqamule amandla futhi anciphise umonakalo obangelwa ukugcwala kwamandla kagesi, iphutha lomhlabathi, isekethe esifushane, noma lapho amandla kagesi edlula umkhawulo wamanje.

Izicelo

Ukusetshenziswa kwama-molded case circuit breakers (ama-MCCB) ezimbonini ezahlukahlukene kushintshe indlela izinhlelo zikagesi ezisebenza ngayo. I-MCCB iyisici esibalulekile sokuqinisekisa ukusebenza okuphephile nokusebenza kahle kwesekethe. Ihlinzeka ngokuvikelwa ekugcwaleni ngokweqile, amasekethe amafushane, kanye namanye amaphutha kagesi, abalulekile ekuvimbeleni izingozi zikagesi kanye nezingozi zomlilo.

Enye yezinzuzo eziyinhloko zama-MCCB yikhono lawo lokuphatha imisinga ephezulu. Aklanyelwe ngqo ukuvikela nokulawula amasekethe anezidingo eziphezulu zamandla. Izimboni ezifana nokukhiqiza, izimayini, uwoyela negesi, kanye nezokuthutha zithembele kakhulu kuma-MCCB ukuvikela imishini yazo ebalulekile kagesi kanye nengqalasizinda. Ikhono lama-MCCB lokuphatha kahle imisinga ephezulu kanye nokunqamula ugesi ngokuzenzakalelayo uma kwenzeka ukugcwala ngokweqile noma ukwehluleka kwenza ama-MCCB abaluleke kakhulu kulezi zimboni.

Enye inzuzo ebalulekile ye-MCCB ukuthi kulula ukuyifaka nokusebenzisa. Zincane ngobukhulu futhi zingafakwa kalula kuma-switchboard nama-switchboard. Ukwakheka kwazo kwe-modular kuvumela ukucushwa okuguquguqukayo, okwenza zivumelane nezidingo ezahlukene zokufakwa. Ngaphezu kwalokho, ama-MCCB atholakala ezinhlobonhlobo zamandla kagesi alinganisiwe, okuqinisekisa ukuhambisana nemithwalo kagesi ehlukahlukene. Ukulula kokufakwa nokusetshenziswa kwenza ama-MCCB abe ukukhetha okuthandwayo kokufakwa okusha nokulungiswa kabusha kwezinhlelo zikagesi ezikhona.

Ukunemba nokuthembeka kwama-MCCB kudlala indima ebalulekile ekuqinisekiseni ukusebenza okungenakuphazamiseka kwezinhlelo zikagesi. Ama-MCCB anezindlela zokuhamba ezithuthukisiwe ezibona futhi ziphendule ngokunembile amaphutha kagesi. Ahlonyiswe ngezinhlobo ezahlukene zezinzwa nezinzwa ezifana nokushisa, amandla kazibuthe, kagesi, njll., ezingazwa izimo zikagesi ezingavamile. Uma iphutha selitholakele, i-MCCB iyawa futhi inqamule ugesi ngokushesha, ivimbele noma yimuphi umonakalo owengeziwe.

Ama-MCCB nawo asiza ekuthuthukiseni ukusebenza kahle kwamandla kwezinhlelo zikagesi. Ngokuvikela ngempumelelo ukwehluleka kukagesi kanye nokulayisha ngokweqile, avimbela ukukhiqizwa kokushisa ngokweqile kanye nokuchitha ugesi okungadingekile. Lokhu akugcini nje ngokunciphisa ingozi yokulimala kwemishini, kodwa futhi kuthuthukisa ukusetshenziswa kwamandla. Njengoba abantu begcizelela kakhulu ukonga amandla kanye nentuthuko esimeme, ukusetshenziswa kwama-molded case circuit breakers kubalulekile ukuqinisekisa ukusebenza okuphumelelayo nokunobungani nemvelo ezimbonini ezahlukene.

Ngamafuphi, ukusetshenziswa kabanzi kwama-molded case circuit breakers kuthuthukise kakhulu ukuphepha, ukuthembeka kanye nokusebenza kahle kwezinhlelo zikagesi ezimbonini ezahlukahlukene. Amandla azo okusingatha imisinga ephezulu, ukulula kokufakwa, ukutholwa kwamaphutha okunembile, kanye nokufaka isandla ekusebenzeni kahle kwamandla kuzenza zibe yizingxenye ezibalulekile ekuvikelweni nasekulawulweni kukagesi. Njengoba ubuchwepheshe buthuthuka, ama-molded case circuit breakers ayaqhubeka nokukhula ukuze ahlangabezane nezidingo ezikhulayo zezinhlelo zikagesi zanamuhla. Njengoba izimboni ziqhubeka nokuthembela ekufakweni kukagesi ukuze zisebenze, indima ye-MCCB ekuqinisekiseni ukusebenza okuphephile nokusebenza kahle kwama-circuit izoba yinto ebaluleke kakhulu.
