Nchiyani Chimapangitsa MCCB & MCB Kufanana?
Ma circuit breakers ndi zinthu zofunika kwambiri pamakina amagetsi chifukwa amapereka chitetezo kumayendedwe amfupi komanso ma overcurrent. Mitundu iwiri yodziwika bwino ya ophwanya ma circuit ndi ma mold case circuit breakers (MCCB) ndi ma miniature circuit breakers(MCB). Ngakhale adapangidwa kuti azikula mosiyanasiyana komanso mafunde, ma MCCB ndi ma MCB onse amagwira ntchito yofunika kwambiri poteteza makina amagetsi. Mu blog iyi, tiwona kufanana ndi kufunika kwa mitundu iwiriyi ya ophwanya madera.
Zofanana zamagwiritsidwe:
MCCB ndiMCBali ndi zofanana zambiri muzochita zapakati. Amakhala ngati masiwichi, kusokoneza kuyenda kwa magetsi pakachitika vuto lamagetsi. Mitundu yonse iwiri yophwanyira dera idapangidwa kuti iteteze makina amagetsi kuti asachuluke komanso mabwalo amfupi.
Chitetezo chozungulira pafupi:
Mayendedwe afupiafupi amakhala ndi chiopsezo chachikulu pamakina amagetsi. Izi zimachitika pamene kugwirizana kosayembekezereka kumachitika pakati pa ma conductor awiri, kuchititsa kuphulika kwadzidzidzi kwa magetsi. Ma MCCB ndi ma MCB ali ndi makina oyenda omwe amazindikira kuchuluka kwa madzi, kuswa dera ndikuletsa kuwonongeka kulikonse kapena ngozi yamoto.
Chitetezo chambiri:
M'makina amagetsi, mikhalidwe yopitilira muyeso imatha kuchitika chifukwa cha kutha kwamphamvu kwambiri kapena kulemetsa. MCCB ndi MCB amathana ndi zinthu ngati izi podula dera. Izi zimalepheretsa kuwonongeka kulikonse kwa zida zamagetsi ndikuthandizira kukhazikika kwa dongosolo lamagetsi.
Magetsi ndi mavoti apano:
MCCB ndi MCB zimasiyana mu kukula kwa dera komanso momwe zikuyendera panopa. Ma MCCB nthawi zambiri amagwiritsidwa ntchito m'mabwalo akuluakulu kapena mabwalo okhala ndi mafunde apamwamba, nthawi zambiri kuyambira 10 mpaka masauzande a ma amps. Komano, ma MCB ndi abwino kwa mabwalo ang'onoang'ono, omwe amapereka chitetezo pakati pa 0.5 mpaka 125 amps. Ndikofunikira kusankha mtundu woyenera wa ophwanyira dera potengera zofunikira zamagetsi kuti zitsimikizire chitetezo chogwira ntchito.
Njira yaulendo:
Onse a MCCB ndi MCB amagwiritsa ntchito njira zodumphadumpha kuti ayankhe zovuta zomwe zikuchitika. Makina odumphira mu MCCB nthawi zambiri amakhala ngati matenthedwe amagetsi omwe amaphatikiza zinthu zomwe zimatenthedwa ndi maginito. Izi zimawathandiza kuti athe kuyankha mochulukira komanso mikhalidwe yayifupi yozungulira. Komano, ma MCB nthawi zambiri amakhala ndi njira yothamangitsira yomwe imakhudzidwa makamaka ndi kuchuluka kwa zinthu. Mitundu ina yapamwamba ya MCB imaphatikizanso zida zamagetsi zodumphadumpha kuti muyende bwino komanso mwasankha.
Zotetezeka komanso zodalirika:
MCCB ndi MCB zimagwira ntchito yofunikira pakuwonetsetsa chitetezo ndi kudalirika kwamagetsi amagetsi. Popanda zowononga madera izi, chiwopsezo chamoto wamagetsi, kuwonongeka kwa zida, ndi kuvulala komwe kungachitike kwa anthu kumawonjezeka kwambiri. Ma MCCB ndi ma MCB amathandizira kuti makhazikitsidwe amagetsi azikhala otetezeka potsegula nthawi yomweyo chigawocho pakapezeka cholakwika.
