Kumvetsetsa Udindo Wofunika wa Ophwanya Dera Ang'onoang'ono

Zothyola ma circuit breaker zazing'ono (MCBs)Ndi gawo lofunikira kwambiri pamakina anu amagetsi, kuteteza nyumba yanu kapena bizinesi yanu ku ma circuit afupiafupi komanso kudzaza kwambiri. Ndi ang'onoang'ono, osavuta kuyika ndipo amapereka chitetezo chachangu komanso chodalirika cha zolakwika zamagetsi.Ma MCBamagwiritsidwa ntchito kwambiri m'nyumba, m'nyumba zamabizinesi ndi m'malo opangira mafakitale kuti ateteze ku moto wamagetsi ndi zinthu zina zoopsa. Mu blog iyi, tikambirana mozama zina mwa zinthu zofunika kwambiri zaMa MCB, momwe zimagwirira ntchito, komanso chifukwa chake zili zofunika kwambiri pamakina anu amagetsi.

Kodi amachita bwanjizotsekera zazing'ono zimagwira ntchito?

MCB kwenikweni ndi switch yomwe imagwedezeka yokha ikazindikira kuti pali magetsi ambiri kapena kuchuluka kwa magetsi mu dera. Pamene magetsi odutsamo apitirira muyeso wake, amachititsa kuti zinthu zotentha kapena zamaginito mu MCB zigwedezeke ndikusokoneza kuyenda kwa magetsi. MCB idapangidwa kuti igwedezeke mwachangu, nthawi zambiri mkati mwa masekondi, pamene magetsi ambiri kapena ochepa apezeka. Dera likagwa, limasokoneza kuyenda kwa magetsi kudzera mu dera lolakwika ndipo limathandiza kupewa kuwonongeka kwa zida zamagetsi ndi moto wamagetsi womwe ungachitike.

Makhalidwe ofunikira aMCB

MukasankhaMCB, pali zinthu zingapo zofunika kuziganizira, kuphatikizapo mtundu wa choswa magetsi, mlingo wa magetsi, mphamvu yosokoneza magetsi, ndi trip curve. Mtundu wa choswa magetsi uyenera kukhala woyenera pa dongosolo lamagetsi ndi kuchuluka kwa magetsi omwe akunyamula. Mlingo wa magetsi umatsimikizira kuchuluka kwa magetsi omwe akutuluka.MCBakhoza kuthana nayo isanagwe, pomwe mphamvu yosweka ndiyo kuchuluka kwa mphamvu yamagetsi yomwe MCB ingasweke bwino. Mzere wozungulira ndi wofunikira kwambiri chifukwa umatsimikizira momwe MCB imayankhira mwachangu ku overload kapena short circuit ndipo uli ndi ma curve atatu akuluakulu - B curve ya katundu wamba, C curve ya ma mota ndi D curve ya ma transformer amphamvu.

Chitetezo cha overload ndi short circuit

Chitetezo cha katundu wochulukirapo ndiye ntchito yayikulu yaMCBmu dongosolo lamagetsi. Zimateteza zida zanu ndi mawaya kuti asatenthedwe chifukwa cha mphamvu yamagetsi yambiri. Chitetezo cha magetsi afupi ndi ntchito ina yofunika kwambiri ya ma miniature circuit breakers. Magetsi afupi amapezeka pamene pali njira yolunjika pakati pa gwero ndi katundu, zomwe zimapangitsa kuti magetsi achuluke komanso chiopsezo chachikulu cha moto wamagetsi. Mu mkhalidwe woopsa uwu, MCB imagunda mwachangu, kuletsa magetsi ena kuyenda komanso kuteteza makinawo ku kuwonongeka komwe kungachitike.

Pomaliza

Pomaliza,MCBndi gawo lofunika kwambiri komanso lofunika kwambiri pamakina amagetsi. Amateteza nyumba yanu kapena bizinesi yanu ku zinthu zodzaza ndi magetsi komanso ma circuit afupiafupi, kuteteza zida zanu ndikupewa zinthu zomwe zingakhale zoopsa. MCB yoyenera iyenera kusankhidwa pamakina anu, poganizira zinthu monga magetsi oyesedwa, kusokoneza mphamvu ndi trip curve. Kusamalira ndi kuyang'anira pafupipafupi ma MCB anu kudzaonetsetsa kuti akupitilizabe kugwira ntchito zawo zofunika kwambiri, kuteteza makina anu amagetsi ndikuwonetsetsa kuti ali otetezeka.
