Iyini i-MCCB?

Iziqephu zesekethe ezibunjiwe zingamathuluzi okuvikela kagesi aklanyelwe ukuvikela isekethe kagesi kusukela kumanje ngokweqile.Lokhu kwamanje okweqile kungadalwa ngenxa yokugcwala ngokweqile noma isifunda esifushane.Izinqamuli zesekethe ezibunjiwe zingasetshenziswa ezinhlobonhlobo zama-voltage namafrikhwensi anomkhawulo ochaziwe ophansi nangaphezulu wezilungiselelo zohambo ezilungisekayo.Ngokungeziwe ezindleleni zokukhubeka, ama-MCCB angasetshenziswa njengamaswishi okunqanyulwa mathupha esimweni esiphuthumayo noma sokulungisa.Ama-MCCB amisiwe futhi ahlolelwe i-overcurrent, ukukhuphuka kwamandla kagesi, nokuvikelwa kwamaphutha ukuze kuqinisekiswe ukusebenza okuphephile kuzo zonke izindawo nezinhlelo zokusebenza.Asebenza ngokuphumelelayo njengeswishi yokusetha kabusha isekethe kagesi ukuze anqamule amandla futhi anciphise umonakalo odalwe ukugcwala kwesekhethi, iphutha eliphansi, amasekhethi amafushane, noma lapho i-current idlula umkhawulo wamanje.

 

Izinhlelo zokusebenza

Ukusetshenziswa kwama-molded case circuit breakers (MCCBs) ezimbonini ezihlukahlukene kuguqule indlela amasistimu kagesi asebenza ngayo.I-MCCB iyingxenye ebalulekile yokuqinisekisa ukusebenza okuphephile nokusebenza kahle kwesekethe.Zinikeza isivikelo ekulayisheni ngokweqile, amasekhethi amafushane, namanye amaphutha kagesi, okubalulekile ekuvimbeleni izingozi zikagesi nobungozi bomlilo.

Enye yezinzuzo eziyinhloko zama-MCCB amandla awo okuphatha imisinga ephezulu.Zenzelwe ngokukhethekile ukuvikela nokulawula amasekhethi anezidingo eziphezulu zamandla.Izimboni ezifana nokukhiqiza, izimayini, uwoyela negesi, nezokuthutha zithembele kakhulu kuma-MCCBs ukuvikela izisetshenziswa zawo zikagesi ezibalulekile nengqalasizinda.Ikhono lama-MCCB okusingatha kahle imisinga ephezulu futhi anqamule ngokuzenzakalelayo amandla uma kwenzeka kugcwala kakhulu noma ukwehluleka kwenza ama-MCCB abaluleke kakhulu kulezi zimboni.

Enye inzuzo ebalulekile ye-MCCB kulula ukuyifaka nokusetshenziswa kwayo.Ahlangene ngosayizi futhi angahlanganiswa kalula kuma-switchboards nama-switchboards.Idizayini yabo ye-modular ivumela ukucushwa okuguquguqukayo, okubenza bavumelane nezimfuneko zokufaka ezihlukene.Ngaphezu kwalokho, ama-MCCB atholakala ezinhlobonhlobo zemisinga elinganisiwe, eqinisekisa ukuhambisana nemithwalo ehlukahlukene kagesi.Ukufakeka kalula nokusetshenziswa kwenza ama-MCCBs abe yinketho edumile yokufaka okusha kanye nokubuyiselwa kumasistimu kagesi akhona.

Ukunemba nokuthembeka kwama-MCCB adlala indima ebalulekile ekuqinisekiseni ukusebenza okungaphazamiseki kwezinhlelo zikagesi.Ama-MCCB anezindlela ezithuthukile zohambo ezihlonza ngokunembile futhi ziphendule amaphutha kagesi.Afakwe izinhlobo ezahlukene zezinzwa nezinzwa ezifana ne-thermal, magnetic, electronic, njll., ezikwazi ukuzwa izimo ezingavamile zikagesi.Uma iphutha selitholakele, i-MCCB iyahamba futhi inqamule amandla ngokushesha, ivimbele noma yimuphi omunye umonakalo.

Ama-MCCB asiza futhi ukuthuthukisa ukusebenza kahle kwamandla kagesi kumasistimu kagesi.Ngokuvikela ngempumelelo ekuhlulekeni kukagesi kanye nokulayishwa ngokweqile, kuvimbela ukukhiqizwa kokushisa ngokweqile nokumosha ugesi okungadingekile.Lokhu akugcini nje ukunciphisa ingozi yokulimala kwemishini, kodwa futhi kuthuthukisa ukusetshenziswa kwamandla.Njengoba abantu begcizelela ngokwandayo ekongeni amandla kanye nentuthuko esimeme, ukusetshenziswa kwama-circuit breakers abunjiwe kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokunobungani kwemvelo ezimbonini ezahlukahlukene.

Ngamafuphi, ukusetshenziswa okubanzi kwama-circuit breakers abunjiwe kuye kwathuthukisa kakhulu ukuphepha, ukwethembeka nokusebenza kahle kwezinhlelo zikagesi ezimbonini ezihlukahlukene.Ikhono lazo lokusingatha imisinga ephezulu, ukuzifaka kalula, ukutholwa kwamaphutha okunembile, kanye negalelo ekusebenzeni kahle kwamandla kuzenza izingxenye ezibalulekile ekuvikeleni nasekulawuleni ugesi.Njengoba ubuchwepheshe buthuthuka, izigebengu zesekethe ezibunjiwe ziyaqhubeka nokuvela ukuze zihlangabezane nezidingo ezikhulayo zezinhlelo zikagesi zesimanje.Njengoba izimboni ziqhubeka nokuthembela ekufakweni kukagesi ukuze zisebenze, indima ye-MCCB yokuqinisekisa ukuthi amasekhethi asebenza ngendlela ephephile futhi ephumelelayo izobaluleka kakhulu.
