MCB ndi chipangizo cha electromechanical chomwe chimazimitsa dera lokha ngati chadziwika.MCB imamva mosavuta kuchulukira komwe kumachitika chifukwa chafupikitsa.Dera laling'ono lili ndi mfundo yowongoka kwambiri yogwirira ntchito.Kuphatikiza apo, ili ndi ma kulumikizana awiri;imodzi yokhazikika ndi ina yosunthika.
Ngati kuchulukiraku kukuwonjezeka, zolumikizira zosunthika zimachotsedwa pazolumikizana zokhazikika, zomwe zimapangitsa kuti chigawocho chitseguke ndikuzichotsa pagawo lalikulu.
A Miniature Circuit Breaker ndi chipangizo cha electromechanical chopangidwa kuti chiteteze dera lamagetsi kuti lisapitirire pakalipano - Mawu ofotokozera vuto lamagetsi lomwe limayambitsidwa ndi kuchulukana kapena kufupikitsa.

Onani ZambiriKuteteza Kwambiri ndi Kutetezedwa Kwafupipafupi: Ma MCB adapangidwa kuti aziteteza mabwalo amagetsi kuti asachuluke komanso mabwalo amfupi.Amangoyendayenda ndikusokoneza dera pakakhala kuthamanga kwambiri, kulepheretsa mawaya ndi zida zamagetsi.
Nthawi Yoyankha Mwamsanga: Ma MCB amakhala ndi nthawi yoyankha mwachangu, nthawi zambiri mkati mwa ma milliseconds, kuti asokoneze dera pakachulukidwa kapena kufupika.Izi zimathandiza kuchepetsa chiopsezo cha kuwonongeka kwa dongosolo ndi kuchepetsa kuthekera kwa moto wamagetsi kapena zoopsa.
Kusavuta komanso Kugwiritsa Ntchito Mosavuta: Ma MCB amapereka mosavuta komanso mosavuta kugwiritsa ntchito poyerekeza ndi ma fuse achikhalidwe.Pakachulukirachulukira kapena dera lalifupi, ma MCB amatha kukhazikitsidwa mosavuta, kubwezeretsa mphamvu kudera mwachangu.Izi zimathetsa kufunika kosintha ma fuse, kupulumutsa nthawi komanso zovuta.
Kutetezedwa kwa Dera Losankha: Ma MCB amapezeka pamasinthidwe osiyanasiyana apano, kukulolani kuti musankhe mavoti oyenera pagawo lililonse.Izi zimathandizira kutetezedwa kwa dera losankhidwa, kutanthauza kuti dera lokhalo lomwe lakhudzidwa lidzagwedezeka, pomwe mabwalo ena akugwirabe ntchito.Izi zimathandiza kuzindikira ndikulekanitsa dera lolakwika, kupangitsa kuti mavutowo athetse komanso kukonza bwino.
Ntchito Yosiyanasiyana: Ma MCB ndi oyenera kugwiritsa ntchito zosiyanasiyana, kuyambira nyumba zogona mpaka nyumba zamalonda ndi mafakitale.Atha kugwiritsidwa ntchito kuteteza mabwalo owunikira, malo opangira magetsi, ma mota, zida, ndi katundu wina wamagetsi.
Kudalirika ndi Ubwino: Ma MCB amamangidwa pamiyezo yapamwamba kwambiri, kuwonetsetsa kuti magwiridwe antchito odalirika komanso kukhazikika kwanthawi yayitali.Amayesedwa mwamphamvu ndikutsata miyezo yamakampani kuti apereke yankho lodalirika lachitetezo chamagetsi anu.
Njira Yothandizira Mtengo: Ma MCB amapereka njira yotsika mtengo yotetezera dera poyerekeza ndi njira zina.Ndi zotsika mtengo, zimapezeka mosavuta pamsika, ndipo zimafunikira chisamaliro chochepa.
Chitetezo: Ma MCB amatenga gawo lofunikira pakupititsa patsogolo chitetezo chamagetsi.Kuphatikiza pa kuchulukitsitsa kwawo komanso kuthekera kwawo kwachitetezo chafupipafupi, ma MCB amatetezanso kugwedezeka kwamagetsi ndi zolakwika zomwe zimachitika chifukwa cha kuwonongeka kwa nthaka kapena mafunde akutuluka.Izi zimathandiza kuonetsetsa chitetezo cha okhalamo ndi kuchepetsa chiopsezo cha zoopsa zamagetsi.
Tumizani Mafunso LeroA Miniature Circuit Breaker (MCB) ndi mtundu wa chipangizo choteteza magetsi chomwe chimagwiritsidwa ntchito kuzimitsa chigawo chamagetsi ngati chiwombankhanga chowonjezera, champhamvu kwambiri, kapena chachifupi.
MCB imagwira ntchito pozindikira mphamvu yomwe ikuyenda pamagetsi.Ngati yapano ipitilira mulingo wapamwamba kwambiri wa MCB, imangoyenda ndikusokoneza dera.
MCB ndi fusesi zonse zimapereka chitetezo chamagetsi, koma zimagwira ntchito mosiyana.Fuse ndi chipangizo chogwiritsidwa ntchito kamodzi chomwe chimasungunula ndikuchotsa dera ngati pompopompo ikwera kwambiri, pomwe MCB imatha kukhazikitsidwanso ikayenda ndikupitiliza kupereka chitetezo.
Pali mitundu ingapo ya MCBs kupezeka, kuphatikizapo matenthedwe maginito MCBs, zamagetsi MCBs, ndi chosinthika ulendo MCBs.
MCB yoyenera pa ntchito inayake imadalira zinthu monga momwe dera likukhalira, mtundu wa katundu womwe ukuyendetsedwa, ndi mtundu wa chitetezo chofunikira.Ndikofunika kukaonana ndi katswiri wamagetsi kapena injiniya kuti mudziwe MCB yoyenera pa ntchito inayake.
Muyezo wapano wa ma MCBs umasiyanasiyana, koma zofananira ndi 1A, 2A, 5A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, ndi 63A.
Ma MCB amtundu wa B adapangidwa kuti aziteteza ku zomwe zikuchitika mopitilira apo, pomwe mtundu wa C MCB adapangidwa kuti aziteteza ku mabwalo opitilira apo ndi aafupi.
Kutalika kwa moyo wa MCB kumadalira zinthu zingapo, kuphatikizapo mafupipafupi ndi kuopsa kwa maulendo, chilengedwe, ndi mtundu wa chipangizocho.Nthawi zambiri, ma MCB amakhala ndi moyo kwazaka makumi angapo ndikusamalidwa bwino komanso kugwiritsidwa ntchito moyenera.
Ngakhale kuti ndizotheka kusintha MCB nokha, nthawi zambiri timalimbikitsidwa kuti katswiri wamagetsi yekha ndi amene angagwire ntchitoyi.Izi zili choncho chifukwa kuyika kolakwika kwa MCB kungayambitse mikhalidwe yopanda chitetezo ndikuchotsa chitsimikizo cha wopanga.
Kuyesa MCB nthawi zambiri kumachitika pogwiritsa ntchito ma voltage tester kapena multimeter.Chipangizocho chikhoza kuyesedwa poyesa voteji kudutsa chosweka pamene chiri pa "pa" malo, ndiyeno kachiwiri pamene chiri pa "off" malo pambuyo popunthwa wosweka.Ngati voteji ilipo pa "off", chophwanyacho chingafunikire kusinthidwa.
