MCCB vs MCB vs RCBO: Akutanthauza Chiyani?

MCCB ndi chowotcha chozungulira, ndipo MCB ndi chodulira chocheperako. Onsewa amagwiritsidwa ntchito m'mabwalo amagetsi kuti apereke chitetezo chambiri. Ma MCCB amagwiritsidwa ntchito pamakina akuluakulu, pomwe ma MCB amagwiritsidwa ntchito m'mabwalo ang'onoang'ono.

RCBO ndi kuphatikiza kwa MCCB ndi MCB. Amagwiritsidwa ntchito m'mabwalo omwe chitetezo cha overcurrent ndi chachifupi chimafunikira. Ma RCBO ndi ocheperako kuposa ma MCCB kapena MCB, koma akukula kutchuka chifukwa cha kuthekera kwawo kupereka mitundu iwiri yachitetezo pachida chimodzi.

Ma MCCB, MCBs, ndi RCBOs onse amagwira ntchito yofanana: kuteteza mabwalo amagetsi kuti asawonongeke chifukwa cha kuchuluka kwa zinthu zomwe zikuchitika. Komabe, aliyense ali ndi ubwino ndi kuipa kwake. MCCBs ndi zazikulu komanso zodula kwambiri mwa njira zitatuzi, koma zimatha kuthana ndi mafunde okwera komanso kukhala ndi moyo wautali.

Ma MCB ndi ang'onoang'ono komanso otsika mtengo, koma amakhala ndi moyo waufupi ndipo amatha kuthana ndi mafunde otsika.Ma RCBO ndi otsogola kwambirimwina, ndipo amapereka ubwino wa MCCBs ndi MCBs mu chipangizo chimodzi.

Ngati pali vuto lomwe lapezeka mudera, MCB kapena kabotolo kakang'ono kamene kamazimitsa dera. Ma MCB adapangidwa kuti azizindikira mosavuta pakakhala mafunde kwambiri, zomwe zimachitika pakakhala kuzungulira kwakanthawi.

Kodi MCB imagwira ntchito bwanji? Pali mitundu iwiri yolumikizirana mu MCB - imodzi yokhazikika ndi ina yosunthika. Pamene panopa ikuyenda mozungulira dera ikuwonjezeka, imapangitsa kuti omvera osunthika asamagwirizane ndi omwe adakhazikika. Izi "zimatsegula" bwino dera ndikuyimitsa kutuluka kwa magetsi kuchokera kuzinthu zazikulu. Mwanjira ina, MCB imagwira ntchito ngati chitetezo choteteza mabwalo kuti asachuluke komanso kuwonongeka.

MCCB (Molded Case Circuit Breaker)

Ma MCCB adapangidwa kuti ateteze dera lanu kuti lisakule kwambiri. Amakhala ndi makonzedwe awiri: imodzi ya overcurrent ndi ina ya kutentha kwambiri. Ma MCCB alinso ndi chosinthira pamanja chodulira dera, komanso kulumikizana ndi bimetallic komwe kumakulitsa kapena kutsika kutentha kwa MCCB kukasintha.

Zinthu zonsezi zimabwera palimodzi kuti apange chipangizo chodalirika, chokhazikika chomwe chingathandize kuti dera lanu likhale lotetezeka. Chifukwa cha kapangidwe kake, MCCB ikhoza kukhala chisankho chabwino pazogwiritsa ntchito zosiyanasiyana.

MCCB ndi chodulira chigawo chomwe chimathandiza kuteteza zida kuti zisawonongeke podula cholumikizira chachikulu pomwe chapano chikuposa mtengo wokhazikitsidwa kale. Pamene kuwonjezereka kwamakono, okhudzana ndi MCCB amakula ndi kutentha mpaka atatsegula, potero akuphwanya dera. Izi zimalepheretsa kuwonongeka kwina mwa kupeza zipangizo kuchokera kuzinthu zazikulu.

Nchiyani Chimapangitsa MCCB & MCB Kufanana?

Ma MCCBs ndi MCBs onse ndi ophwanya madera omwe amapereka chitetezo kudera lamagetsi. Amagwiritsidwa ntchito kwambiri m'mabwalo ocheperako ndipo amapangidwa kuti azitha kuzindikira ndikuteteza dera kumayendedwe amfupi kapena ma overcurrent.

Ngakhale amagawana zofanana zambiri, ma MCCB amagwiritsidwa ntchito ngati mabwalo akuluakulu kapena omwe ali ndi mafunde apamwamba, pomwe ma MCB ndi oyenerera mabwalo ang'onoang'ono. Mitundu yonse iwiri yamagetsi ozungulira imakhala ndi gawo lofunikira pakuwonetsetsa chitetezo chamagetsi.

Chosiyanitsa MCCB ndi MCB ndi Chiyani?

Kusiyana kwakukulu pakati pa MCB ndi MCCB ndi kuthekera kwawo. MCB ili ndi ma amps ochepera 100 okhala ndi ma amps ochepera 18,000, pomwe MCCB imapereka ma amps otsika mpaka 10 komanso mpaka 2,500. Kuphatikiza apo, MCCB imakhala ndi chosinthika chaulendo wamamodeli apamwamba kwambiri. Zotsatira zake, MCCB ndi yoyenera kwa mabwalo omwe amafunikira mphamvu yayikulu.

Zotsatirazi ndi zina zofunika kwambiri kusiyana pakati pa mitundu iwiri ya ma circuit breakers:

MCCB ndi mtundu wina wa ophwanya dera omwe amagwiritsidwa ntchito kuwongolera ndi kuteteza makina amagetsi. Ma MCB nawonso ndi ophwanya madera koma amasiyana chifukwa amagwiritsidwa ntchito pazida zapakhomo komanso mphamvu zochepa.

Ma MCCB atha kugwiritsidwa ntchito kumadera omwe amafunikira mphamvu zambiri, monga mafakitale akulu.

Zithunzi za MCBskukhala ndi dera lokhazikika loyenda pomwe pa MCCBs, dera loyenda limasunthika.

Pankhani ya ma amps, ma MCB ali ndi ma amps ochepera 100 pomwe ma MCCB amatha kukhala ndi ma amps a 2500.

Sizotheka kuyatsa ndi kuzimitsa MCB kutali pomwe ndizotheka kutero ndi MCCB pogwiritsa ntchito waya wa shunt.

Ma MCCB amagwiritsidwa ntchito makamaka ngati pali mafunde olemera kwambiri pomwe ma MCB amatha kugwiritsidwa ntchito pamagawo aliwonse otsika.

Chifukwa chake, ngati mukufuna chotchingira panyumba panu, mutha kugwiritsa ntchito MCB koma ngati mukufuna yopangira mafakitale, mutha kugwiritsa ntchito MCCB.
