Ma mold case circuit breakers ndi zida zotetezera magetsi zomwe zimapangidwira kuteteza dera lamagetsi kuti lisawonongeke kwambiri.Kuchulukirachulukiraku kumatha kuchitika chifukwa chakuchulukirachulukira kapena kuzungulira kwafupipafupi.Zowonongeka zowonongeka zimatha kugwiritsidwa ntchito pamagetsi osiyanasiyana ndi mafupipafupi ndi malire otsika komanso apamwamba a maulendo osinthika.Kuphatikiza pa njira zodumphadumpha, ma MCCB atha kugwiritsidwanso ntchito ngati ma switch olumikizira pamanja pakachitika ngozi kapena kukonza.Ma MCCB amakhala okhazikika ndikuyesedwa kuti azitha kupitilira, kuthamanga kwamagetsi, komanso chitetezo cha zolakwika kuti zitsimikizire kuti zikugwira ntchito motetezeka m'malo onse ndikugwiritsa ntchito.Amagwira ntchito bwino ngati chosinthira chosinthira chamagetsi kuti achotse mphamvu ndikuchepetsa kuwonongeka komwe kumachitika chifukwa cha kuchuluka kwa dera, vuto lapansi, mabwalo amfupi, kapena pomwe pano chikupitilira malire omwe alipo.
MCCB kapena fuse ndi chinthu chamagetsi chomwe chimagwiritsidwa ntchito kwambiri m'makampani kuteteza zida ndi makina amagetsi.M'moyo watsiku ndi tsiku, MCCB imagwiritsidwa ntchito kwambiri.Ntchito zina zodziwika bwino za MCCB zafotokozedwa pansipa.
1.Kugawa kwamagetsi: MCCB ingathandize oyika kugawa katundu wa gridi ku zipangizo zosiyanasiyana zamagetsi.Kupyolera mu MCCB, ogwiritsa ntchito amatha kuwongolera bwino kagawidwe ka magetsi komanso momwe chipangizocho chilili.
2.Chitetezo chafupipafupi: Ntchito yaikulu ya MCCB ndiyo kudula dera pamene dera lalifupi likuchitika.Izi zimapewa kuwonongeka kwa zida, kumasulidwa kwa zinthu zoopsa monga moto.
Kutetezedwa kwa 3.Overload: Mofanana ndi chitetezo chafupipafupi, MCCB ingatetezenso zipangizo kuti zisakulemedwe.Izi zitha kutheka pokhazikitsa zowononga magetsi kuti zipewe kuwonongeka kwamagetsi chifukwa chodzaza zida.
Chitetezo cha 4.Jenereta: MCCB imagwiritsidwa ntchito kwambiri pozindikira ndi kuteteza majenereta akuluakulu.Itha kuwunika momwe jenereta imagwirira ntchito, kuzindikira zovuta ndikuyambitsa chitetezo chamagetsi.
Chitetezo cha 5.Power Transformer: MCCB imatha kuletsa thiransifoma kudzaza ndikuyang'anira kutentha kwambiri kwa transformer nthawi yomweyo.
6.Chitetezo cha cylinder: MCCB imagwiritsidwa ntchito kwambiri mu konkire, simenti ndi ma crushers a mchere.Imazindikira mabwalo amfupi ndi zida zochulukira, potero zimateteza zida kuti zisawonongeke.
Pomaliza, ma MCCB amagwiritsidwa ntchito kwambiri ndipo amagwira ntchito yofunika kwambiri pamagawo osiyanasiyana amagetsi ndi makina.Posankha MCCB, zinthu zingapo zapadera ziyenera kuganiziridwa mosamala kuti zitsimikizire chitetezo ndi kudalirika kwa dongosololi, kuphatikizapo mphamvu zamakono, mphamvu, malo ogwiritsira ntchito, ndi zina zofunika.
