Udindo wa MCB

Chotsekera dera chaching'ono (MCB) amagwira ntchito yofunika kwambiri pakuonetsetsa kuti zipangizo zapakhomo ndi zida zamagetsi zili ndi chitetezo komanso chitetezo. Ma Miniature circuit breakers amagwiritsidwa ntchito kwambiri popewa kupitirira muyeso, ma short circuit ndi kutuluka kwa madzi, motero amateteza zida kuti zisawonongeke komanso kuchepetsa kugwiritsa ntchito mphamvu. Kukula kwawo kochepa, kusavuta kuyika, kudalirika kwambiri komanso kugwiritsa ntchito bwino ndalama kumapangitsa kuti zikhale zofunika kwambiri m'makina amagetsi.

Chimodzi mwa ntchito zazikulu za MCBs ndikupereka chitetezo cha short circuit. Pamene vuto la short circuit lachitika ndipo mphamvu yamagetsi mu mzere ndi yayikulu kwambiri, miniature circuit breaker imagwiritsa ntchito mphamvu ya electromagnetic yopangidwa ndi electromagnetic coil kuyendetsa pakati pa chitsulo, kukankhira ndodo kuti itsegule, ndikudula dera mkati mwa nthawi yochepa. Zosakwana masekondi 0.1. Kuyankha mwachangu kumeneku ku vuto la short circuit kumathandiza kupewa kuwonongeka kwa zida ndikuwonetsetsa kuti machitidwe amagetsi ndi otetezeka.

Kuwonjezera pa chitetezo cha mafunde afupiafupi, ma MCB amapangidwanso kuti apereke chitetezo cha mafunde ochulukirapo. Pamene mafunde omwe ali mu mzere apitirira mafunde oyesedwa koma akadali otsika kuposa mtengo wamagetsi afupiafupi omwe adakhazikitsidwa, zomwe zimapangitsa kuti pakhale vuto la mafunde ochulukirapo, chinthu cha bimetallic cha kutentha chomwe chili mu miniature circuit breaker chimapindika ndikukana loko, motero chimaswa mafunde. Nthawi yosweka imasintha malinga ndi kukula kwa mafunde ochulukirapo, ndipo kukula kwa mafunde osiyanasiyana kumayenderana ndi madigiri osiyanasiyana ochedwa. Izi zimathandiza kupewa zida kuti zisatenthe kwambiri komanso kuwonongeka komwe kungachitike chifukwa cha mafunde ochulukirapo kwa nthawi yayitali.

Poganizira za mphamvu yothyola ya ma MCB, ndikofunikira kudziwa kuti apangidwa kuti agwirizane ndi mphamvu zosiyanasiyana zothyola ma circuit breaker. Mphamvu yothyola ma circuit breaker (Icn) ya ma general small circuit breaker nthawi zambiri imakhala 6A mpaka 63A, pomwe mphamvu yothyola ma circuit breaker ang'onoang'ono a 6A mpaka 40A ndi 6KA, ndipo mphamvu yothyola ma circuit breaker ang'onoang'ono a 50A mpaka 63A ndi 4.5KA. Kuphatikiza apo, mphamvu yothyola ma circuit breaker (Ics) yogwira ntchito imatchulidwanso kuti ndi 6KA ya ma circuit breaker ang'onoang'ono a 6A mpaka 40A ndi 4.5KA ya ma circuit breaker ang'onoang'ono a 50A mpaka 63A. Mphamvu yothyola iyi imatsimikizira kuti ma circuit breaker ang'onoang'ono amatha kusokoneza ma circuit mosamala pansi pa mikhalidwe yosiyanasiyana ya ma circuit breaker, ndikuwonjezera chitetezo kumagetsi.

Kusinthasintha kwa MCB komanso kugwira ntchito bwino kwake kumapangitsa kuti ikhale chinthu chofunikira kwambiri poteteza zipangizo zapakhomo ndi zida zamagetsi. Mphamvu zoteteza kutayikira kwa magetsi, ma short circuit ndi kutayikira kwa madzi sizimangoteteza zida zokha komanso zimathandiza kuchepetsa kugwiritsa ntchito mphamvu. Ma MCB ndi ang'onoang'ono, osavuta kuyika, odalirika kwambiri komanso otsika mtengo, omwe amapereka njira yotsika mtengo yotsimikizira chitetezo ndi chitetezo cha makina amagetsi. Kaya ndi ntchito yogwiritsidwa ntchito m'nyumba, m'mabizinesi kapena m'mafakitale, ma miniature circuit breakers ndi ofunikira kwambiri pakusunga umphumphu ndi chitetezo cha makina amagetsi.

Gulu la Mutai lakhala ndi zaka zoposa khumi zogwira ntchito yopanga ndi kugulitsa zinthuzosokoneza ma circuit, zolumikizira, ma switch awiri osinthira okha amagetsi (ATS) ndi madera ena ofanana. Tikuyembekezera mwachidwi mwayi wogwira nanu ntchito.
