Gulu lofunikira kwambiri la ophwanya dera-ACB MCCB MCB

Zowononga kuzungulira, amene ali m’magulu atatu aakulu.

Mtundu woyamba umatchedwaair circuit breakeror air-insulated circuit breaker.Chizindikiro cha chimango Breaker ndiACB, popeza mawu akuti Mpweya ndi Circuit ndipo mawu akuti Breaker ndi Breaker.

Mtundu wachiwiri, wotchedwakuumbidwa mlandu circuit breaker,ndiMtengo wa MCCB;
Mtundu wachitatu ndikakang'ono circuit breaker, amene chizindikiro chake ndiMCB.

Mawerengedwe apano aACB imachokera ku 1250A mpaka 6300A, kuchuluka kwake komwe adavotera;Mawerengedwe apano aMCCB imachokera ku 10A mpaka 1600A, zomwe zidavoteredwa pakati.MCB ili ndi milingo yaying'ono kwambiri, kuyambira 6A mpaka 63A, koma ndiye maziko a ophwanya madera akunyumba.
Ziribe kanthu kuti ndi mtundu wanji, kusungunula pakati pa omwe amalumikizana mkati mwa wowononga dera kumadalira mpweya, chomwe ndichifukwa chake MCB imadziwika kuti switch switch.
Popeza kutchinjiriza pakati pa olumikizana mkati mwa wophwanya dera kumadalira mpweya, ndikofunikira kuti tikambirane za kuwonongeka kwa mpweya, komanso chidziwitso choyambira cha arc.

2. Za arc

Timawona arc ngati mtambo wa gasi wotentha.Mkati mwa arc, pa kutentha pamwamba pa madigiri 3,000, ma elekitironi amatuluka kuchokera ku maatomu kupanga ma ion olakwika, omwe amatayika kotero kuti mamolekyu a mpweya onse ndi plasma, osakaniza ma electron ndi mpweya wabwino wa ionic.

3. Kutsegula mtunda wa wowononga dera

Frame circuit breaker ACB, mtunda waufupi kwambiri pakati pa kukhudzana kosuntha ndi kukhudzana kokhazikika kumatchedwa mtunda wotseguka.
Mtunda wotsegulira umagwiritsidwa ntchito pofuna kuonetsetsa kuti mpweya pakati pa otsegula otsegula sudutsa kuwonongeka kwa magetsi.
