Dziwani Kusiyana Pakati pa Miniature Circuit Breakers ndi Molded Case Circuit Breakers

Mutu: Dziwani Kusiyana Pakati paZosefera Zazing'ono Zazing'onondiOphwanya Mlandu Wopangidwa ndi Dera

Ma circuit breaker ndi gawo lofunikira kwambiri pamagetsi a nyumba. Amathandiza kuteteza nyumba yanu, ofesi kapena malo amalonda ku magetsi ambiri komanso ma short circuit. Ma circuit breaker awiri omwe amagwiritsidwa ntchito kwambiri ndi miniature circuit breaker (MCB) ndi chotsukira ma circuit cha case molded (MCCBNgakhale kuti zonse ziwiri zimagwira ntchito imodzi, pali kusiyana pakati pawo. Mu blog iyi, tifufuza kusiyana kumeneku.

1. Kukula ndi kagwiritsidwe ntchito
Kusiyana kwakukulu pakati paMCBndiMCCBndi kukula kwawo. Monga momwe dzinalo likusonyezera, ma MCB ndi ang'onoang'ono kukula ndipo amagwiritsidwa ntchito m'magetsi otsika mpaka ma amp 125. Amagwiritsidwa ntchito kwambiri m'nyumba ndi m'mabizinesi ang'onoang'ono. Koma ma MCCB ndi akuluakulu ndipo amatha kunyamula magetsi okwera mpaka ma amp 5000. Nthawi zambiri amagwiritsidwa ntchito m'mafakitale ndi m'mabizinesi omwe amafunikira mphamvu zambiri.

2. Yamphamvu komanso yolimba
MCCB ndi yamphamvu komanso yolimba kuposa MCB. Amatha kuthana ndi mphamvu zamagetsi zambiri ndipo adapangidwa kuti azitha kupirira malo ovuta.Ma MCCBnthawi zambiri amapangidwa ndi zinthu zolimba monga ceramic kapena pulasitiki wopangidwa kuposaMa MCB, zomwe nthawi zambiri zimapangidwa ndi nyumba ya pulasitiki. Ma MCB amapangidwira kuti azigwiritsidwa ntchito m'malo osakhala ovuta kwambiri ndipo sayenera kuyikidwa pazida zowononga kwambiri kapena kutentha kwambiri.

3. Njira yoyendera
Ma MCB onse ndiMa MCCBapangidwa kuti agwedezeke pamene mphamvu ya magetsi yapitirira malire enaake. Komabe, njira zomwe amagwiritsa ntchito pogwedezeke ndi zosiyana. MCB ili ndi njira yoyendera maginito yotentha. Njirayi imagwiritsa ntchito mzere wa bimetal womwe umatentha ndikupindika pamene mphamvu ya magetsi yapitirira malire, zomwe zimapangitsa kuti chogwedezeke cha magetsi chigwedezeke. MCCB ili ndi njira yoyendera magetsi yamagetsi yomwe imagwiritsa ntchito microprocessor kuti iwunike kayendedwe ka mphamvu ya magetsi. Mphamvu yamagetsi ikapitirira malire, microprocessor imatumiza chizindikiro kwa chogwedezeke cha magetsi kuti chigwedezeke.

4. Mtengo
Ma MCBnthawi zambiri zimakhala zotsika mtengo kuposaMa MCCBIzi zili choncho chifukwa chakuti ndi zosavuta kupanga komanso zopangidwa ndi zipangizo zotsika mtengo. Komanso sizilimba kwambiri kuposa ma MCCB ndipo zimakhala ndi mphamvu yochepa yonyamulira mphamvu. Ma MCCB ndi okwera mtengo kwambiri chifukwa cha kapangidwe kake kovuta komanso zipangizo zomwe amagwiritsidwa ntchito, koma ndi olimba kwambiri ndipo amatha kunyamula mphamvu zambiri.

5. Kukonza
Kukonza kofunikira kwa ma MCB ndiMa MCCBndi yosiyana kwambiri. MCB ndi yophweka kapangidwe kake ndipo siifuna kukonza kwambiri. Amafunika kuyang'aniridwa nthawi zonse ndi katswiri wamagetsi ndikusinthidwa ngati pali vuto. Koma ma MCCB amafunikira kukonza kowonjezereka, monga kuwunika pafupipafupi mayunitsi apaulendo apamagetsi, omwe amatha kutha ntchito pakapita nthawi ndipo amafunika kusinthidwa.

Mwachidule, MCB ndiMCCBali ndi ntchito yofanana, yomwe ndi kuteteza makina amagetsi ku overload ndi short circuit. Komabe, monga tikuonera, pali kusiyana pakati pa awiriwa. Ma MCB ndi ang'onoang'ono, olimba komanso otsika mtengo, pomweMa MCCBndi olimba, olimba komanso okwera mtengo. Kugwiritsa ntchito ndi zofunikira pakali pano ndi zinthu zazikulu zomwe muyenera kuganizira posankha pakati pa ziwirizi.
