Kusiyana pakati pa ACB ndi MCCB

Choswa dera la mpweya (ACBndichotsukira dera chopangidwa ndi bokosi (MCCB) ndi zida ziwiri zotetezera ma circuit zomwe zimagwiritsidwa ntchito kwambiri m'magetsi. Ngakhale zonse ziwiri zimatumikira ntchito yofunikira yoteteza ma circuit ku zinthu zodzaza ndi zinthu zambiri, ma circuit afupiafupi, ndi zolakwika zina, pali kusiyana kwakukulu pakati pa ziwirizi komwe kumawapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana.

Choyamba, kukula kwa ACB ndi MCCB ndi kosiyana kwambiri. Ma ACB ndi akuluakulu kukula ndi kuchuluka ndipo ali ndi ma rating apano kuyambira 400A mpaka 6300A. Izi zimapangitsa kuti akhale abwino kugwiritsidwa ntchito m'ma network ogawa magetsi, komwe ntchito yawo ndi kugawa mphamvu zamagetsi ndikuteteza mizere ndi zida zamagetsi ku zolakwika zosiyanasiyana. Koma ma MCCB ndi ochepa kukula ndi kuchuluka ndipo ali ndi ma rating apano kuyambira 10A mpaka 800A. Amagwiritsidwa ntchito kwambiri kuteteza mizere yogawa ndi zida ku overloads, short circuits ndi undervoltages, ndipo amathanso kuteteza ntchito zoyambira zamagalimoto.

Kusiyana kwina kofunikira pakati pa ACB ndi MCCB ndi ntchito yawo yoteteza. Choyendetsa chanzeru cha air circuit breaker chili ndi ntchito zambiri zoteteza monga kuteteza kuchedwa kwa nthawi yayitali, kuteteza kuchedwa kwakanthawi kochepa, kuteteza nthawi yomweyo, kuteteza pansi, kuteteza kupitirira mphamvu, ndi chitetezo cha kutayika kwa gawo. Kuphatikiza pa ntchito zoteteza, ACB imaperekanso ntchito zoyezera monga kuyeza kwamakono, kuyeza kwa voltage, kuyeza mphamvu, ndi kuyeza kwa harmonic, komanso ntchito zothandizira monga kuchenjeza koyambirira, kudzizindikira, kujambula mbiri ya zolakwika, ndi ntchito zoyesera. Kuphatikiza apo, ACB ili ndi zida zolumikizirana zomwe zimalola kuphatikizana bwino mu dongosolo lonse lamagetsi. Mosiyana ndi izi, zoyendetsa za case circuit breakers zomwe zimapangidwa mopangidwa makamaka zimapereka chitetezo cha nthawi yayitali, chitetezo cha nthawi yochepa (chitetezo cha overload) ndi chitetezo cha nthawi yomweyo (chitetezo cha short-circuit).

Kuchuluka kwa momwe ACB ndi MCCB zimagwiritsidwira ntchito nakonso n’kosiyana. ACB imagwiritsidwa ntchito makamaka m’maukonde akuluakulu ogawa magetsi chifukwa cha mphamvu zake zamagetsi zambiri komanso ntchito zake zosiyanasiyana zotetezera. Amagwira ntchito yofunika kwambiri poonetsetsa kuti magetsi akuyenda bwino komanso motetezeka popewa zolakwika zosiyanasiyana. Koma ma MCCB amagwiritsidwa ntchito m’malo amalonda ndi mafakitale komwe mphamvu zamagetsi zochepa zimakhala zokwanira kuteteza ku zinthu zopitirira muyeso, ma short circuits, ndi ma undervoltages. Amagwiritsidwa ntchito kwambiri poteteza mizere yogawa magetsi ndi zida komanso kupereka chitetezo pa ntchito zoyambira magalimoto.

Mwachidule, kusiyana pakati pa ACB ndi MCCB kungayambitsidwe ndi kukula kwawo, ntchito zoteteza komanso kuchuluka kwa ntchito. ACB ndi yayikulu kukula kwake ndipo imatha kupereka ntchito zoteteza komanso zoyezera mokwanira ndipo ndiyoyenera kugwiritsidwa ntchito m'maukonde ogawa magetsi, pomwe MCCB ndi yaying'ono ndipo imatha kupereka ntchito zoteteza zofunika pamizere yaying'ono yogawa magetsi ndi zida. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri posankha chipangizo choyenera choteteza magetsi chamakina enaake, kuonetsetsa kuti magwiridwe antchito ndi chitetezo ndi abwino kwambiri.
