Chosweka Mlandu Wopangidwa: Kuonetsetsa Kuti Mphamvu Zikugawidwa Motetezeka Komanso Modalirika

Ophwanya Mlandu Wopangidwa ndi Dera

A chosweka cha circuit cha molded case (MCCB)ndi mtundu wa chotchingira mawaya chomwe chimagwiritsidwa ntchito kwambiri poteteza magetsi m'mafakitale ndi m'mabizinesi chifukwa cha kuthekera kwake kupereka chitetezo chodalirika komanso chotetezeka ku mafunde amphamvu, mawaya afupiafupi ndi mavuto ena amagetsi. M'nkhaniyi, tikambirana mozama zaMa MCCBndikukambirana makhalidwe awo, mfundo zogwirira ntchito, kapangidwe kake, ndi momwe amagwiritsidwira ntchito.

Makhalidwe a MCCB

Ma MCCB apangidwa ndi ntchito zingapo zomwe zimathandiza kuteteza makina amagetsi m'njira yotetezeka komanso yodalirika. Zina mwa zinthu zofunika kwambiri za MCCB ndi izi:

• Kutha kuswa kwakukulu:Zophwanya ma circuit breakers zopangidwa ndi molded caseamatha kuswa mafunde mpaka ma ampere zikwizikwi, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito mphamvu zambiri.
• Njira yoyendera maginito ndi kutentha:Zophwanya ma circuit breakers zopangidwa ndi molded caseGwiritsani ntchito njira yoyendera maginito pogwiritsa ntchito kutentha ndi maginito kuti muzindikire ndikuyankha maginito ochulukirapo komanso maginito afupi. Maginito oyendera maginito amayankha maginito ochulukirapo, pomwe maginito amayankha maginito afupi.
• Kusintha kwa Ulendo: Ma MCCB ali ndi kusintha kwa ulendo, zomwe zimathandiza kuti akhazikitsidwe pamlingo woyenera wa pulogalamu yomwe mukufuna.
• Makulidwe osiyanasiyana a chimango: Ma MCCB amapezeka m'makulidwe osiyanasiyana a chimango, zomwe zimathandiza kuti agwiritsidwe ntchito m'njira zosiyanasiyana. Mfundo yogwirira ntchito ya chotsukira maginito chopangidwa ndi chitoliro chamagetsi Mfundo yogwirira ntchito ya MCCB imachokera pa njira yotchingira maginito yopangidwa ndi kutentha. Chinthu chotenthetsera chimamva kutentha komwe kumapangidwa ndi kuyenda kwa magetsi mu dera ndipo chimatchingira chotsukira maginito pamene magetsi apitirira chiwerengero cha maulendo. Chinthu chotenthetsera maginito chimamva mphamvu ya maginito yopangidwa ndi dera lalifupi mu dera, zomwe zimatchingira chotsukira maginito nthawi yomweyo. Kapangidwe ka chotsukira maginito chopangidwa ndi chitoliro chamagetsi ...
• MCCB imakhala ndi nyumba yapulasitiki yopangidwa ndi pulasitiki yomwe imakhala ndi makina oyendera, zolumikizirana ndi zida zonyamulira magetsi.
• Zolumikizirazo zimapangidwa ndi zinthu zoyendera mphamvu kwambiri monga mkuwa, pomwe njira yoyendera imakhala ndi mzere wa bimetallic ndi coil yamaginito.

Kugwiritsa ntchito MCCB

Ma MCCB amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana monga:

• Dongosolo logawa mphamvu
• Malo Owongolera Magalimoto
• Makina a mafakitale
• Transformers
• Seti ya jenereta

Pomaliza

Ma circuit breaker opangidwa ndi molded case ndi zida zodalirika komanso zothandiza kwambiri zotetezera magetsi. Kapangidwe kake ndi mawonekedwe ake zimapangitsa kuti zikhale zabwino kwambiri kugwiritsidwa ntchito m'njira zosiyanasiyana monga ma transformer, makina ogawa magetsi, ndi malo owongolera magalimoto. Njira yawo yoyendera maginito otenthetsera kutentha, mphamvu yosweka kwambiri komanso malo osinthira maulendo zimapangitsa kuti ikhale njira yotchuka yotetezera magetsi m'malo amalonda ndi mafakitale.
