Kusiyana pakati pa MCB ndi MCCB

Ponena za ma circuit breaker, njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri ndi MCB ndi MCCB. Ngakhale kuti zonsezi zimagwiritsidwa ntchito kuteteza magetsi ku overloads ndi short circuit, pali kusiyana kwakukulu pakati pa zinthu ziwirizi.

Chotsekera dera chaching'ono (MCB), monga momwe dzinalo likusonyezera, ndi chothyola ma circuit breaker chaching'ono chokhala ndi ntchito zambiri. Chimagwiritsidwa ntchito kwambiri m'malo osiyanasiyana monga mafakitale, malonda, nyumba zazitali, ndi nyumba zogona. Ma MCB amapangidwira kuteteza ma terminal distributor amagetsi m'nyumba. Pali mitundu yambiri ndi kuchuluka kwa zinthu zothyola ma circuit breaker, zoyenera kugwiritsidwa ntchito mosiyanasiyana.

Chimodzi mwa ubwino waukulu wa MCB ndi kuthekera kwake kuthana ndi mitundu yosiyanasiyana ya magetsi. Ndi yoyenera kuteteza mizere mopitirira muyeso komanso yofupikitsa ndi magetsi okhala ndi AC 50/60Hz 230/400V komanso magetsi okwana 63A. Kuphatikiza apo, ma circuit breaker ang'onoang'ono angagwiritsidwenso ntchito posintha mizere pafupipafupi pazochitika zachizolowezi. Kusinthasintha kumeneku kumawapangitsa kukhala abwino kwambiri pamakina ambiri amagetsi.

Mbali inayi,zophulitsira ma circuit breakers zopangidwa ndi chipolopolo (MCCB) amagwiritsidwa ntchito makamaka m'makina ogawa mphamvu zamagetsi otsika komanso m'mabwalo oteteza magalimoto. Amapereka chitetezo cha overload ndi short circuit. Chinthu chachikulu chomwe chimasiyanitsa MCCB ndi chivundikiro chake cha pulasitiki, chomwe chimagwira ntchito ngati insulator ndikulekanitsa ma conductor ndi zitsulo zokhazikika. Chifukwa cha kudalirika kwake komanso kukhazikika kwake, ma molded case circuit breakers akhala akugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.

Ngakhale kuti MCB ndi MCCB zonse ndi zotsekereza mawaya, pali kusiyana kwakukulu pakati pawo. Choyamba, ali ndi magawo osiyanasiyana amagetsi ndi makina. MCB ndi yoyenera mawaya okwana masikweya mita 10, pomwe MCCB imatha kulumikiza mawaya okhuthala, monga mawaya opitilira masikweya mita 35. Izi zimathandiza MCCB kunyamula mphamvu ndi mafunde amphamvu kwambiri.

Kusiyana kwina ndi momwe zimalumikizirana. Ma terminal a chosinthira ma case case chopangidwa amalumikizidwa ndi mtedza, womwe ungasindikizidwe mosavuta ndikuwonetsetsa kuti ulumikizana bwino. Mosiyana ndi zimenezi, ma MCB amagwiritsa ntchito ma terminal ang'onoang'ono okakamiza omwe amatha kumangidwa ndi screwdriver yokha. Kusiyana kumeneku kwa njira zolumikizira kumakhudza kupsinjika ndi khalidwe la kukhudzana.

Kuphatikiza apo, MCB ndi MCCB zili ndi malo osiyanasiyana ogwirira ntchito. Ma MCB amapangidwira ntchito zosiyanasiyana, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'malo osiyanasiyana. Koma MCCB imagwiritsidwa ntchito makamaka m'malo osinthira ang'onoang'ono.

Mwachidule, ngakhale kuti ma miniature circuit breakers ndi ma molded case circuit breakers onse amagwiritsidwa ntchito kuteteza magetsi, ali ndi kusiyana kwakukulu. MCB imagwiritsidwa ntchito kwambiri ndipo ili ndi ntchito zosiyanasiyana, pomwe MCCB imagwiritsidwa ntchito makamaka mu ma low-voltage power distribution systems ndi ma motor protection circuits. Amasiyana mu ma parameter amagetsi ndi makina, njira zolumikizirana, ndi malo ogwirira ntchito. Kumvetsetsa kusiyana kumeneku kudzakuthandizani kudziwa kuti ndi circuit breaker iti yomwe ili yoyenera zosowa zanu.
