Kufunika ndi ntchito yazing'ono zozungulira ma circuit breakers

Mutu: Kufunika ndi ntchito yazazing'ono circuit breakers

dziwitsani:

Miniature circuit breakers (MCBs)amagwira ntchito yofunika kwambiri powonetsetsa chitetezo ndi kudalirika kwa machitidwe amagetsi.Zipangizozi zakhala gawo lofunika kwambiri pazitsulo zamakono zamakono, zomwe zimagwiritsidwa ntchito pofuna kuteteza magetsi komanso kuchepetsa kuwonongeka komwe kungatheke.Nkhaniyi ikufotokoza za kufunika ndi ntchito ya alonda ophatikizanawa, kusonyeza kufunika kwawo pa ntchito yamagetsi.

1. Mvetsetsani zomangira zazing'ono:

A kakang'ono circuit breaker, nthawi zambiri amafupikitsidwa ngatiMCB, ndi chosinthira chamagetsi chodziwikiratu chomwe chimapangidwira kuteteza mabwalo amagetsi kumayendedwe opitilira muyeso komanso afupi.Zidazi nthawi zambiri zimayikidwa mu ma switchboards, zida za ogula ndi mabokosi a fuse monga njira yoyamba yodzitetezera ku kulephera kwa magetsi.

2. Zofunikira zazikulu ndi zigawo zake:

Zithunzi za MCBsamadziwika ndi kukula kwawo kophatikizika, nthawi zambiri amakhala malo amodzi mkati mwa switchboard.Komabe, kukula kwawo kochepa kumatsutsa kufunika kwawo pakusunga chitetezo chamagetsi.Zigawo zazikulu zaMCBkuphatikiza makina osinthira, kulumikizana ndi njira yapaulendo.

Makina osinthira amalola kugwiritsa ntchito pamanja, kupangitsa wogwiritsa ntchito kutsegula kapena kutseka dera.Kumbali ina, Contacts ali ndi udindo woyendetsa ndi kusokoneza zomwe zikuchitika kuzungulira dera.Potsirizira pake, makina oyendayenda amazindikira kuti pali njira yodutsa kapena yochepa ndipo imayambitsaMCBkutsegula dera, potero kuteteza dongosolo.

3. Chitetezo chanthawi yayitali:

Imodzi mwa ntchito zazikulu zaMCBndi kupewa overcurrent.Overcurrent imachitika pamene zambiri zamakono zikuyenda mozungulira dera kuposa mphamvu zake zovotera, zomwe zingayambitse kutenthedwa ndi kuwonongeka kwa magetsi.Zithunzi za MCBsyankhani izi mwa kusokoneza nthawi yomweyo dera lamagetsi, motero kupewa kutenthedwa ndi kuchepetsa chiopsezo cha moto wamagetsi.

4. Chitetezo cha dera lalifupi:

Udindo wina wofunikira waMCBndi kuteteza dera lalifupi.Dongosolo lalifupi limachitika pamene kulumikizana mwangozi (nthawi zambiri chifukwa cha kusokonekera kapena kulephera kwa kutchinjiriza) kumapangitsa kuti madzi aziyenda mozungulira.Kuzungulira kochepa kumatha kuwononga kwambiri chipangizocho ndipo kungayambitsenso moto.Nthawi yoyankha mwachangu ya MCB imathandizira kuti izindikire mabwalo afupikitsa ndikusokoneza dera kusanachitike kuwonongeka kwakukulu.

5. Kusiyana ndi fusesi:

Ngakhale ma MCB onse ndi ma fuse amapereka chitetezo ku zovuta zamagetsi, pali kusiyana kwakukulu pakati pa ziwirizi.Ma fuse amakhala ndi mawaya opyapyala kapena timizere tachitsulo timene timasungunula pamene madzi akuyenda kwambiri, kuswa dera.Fuse ikawomba, iyenera kusinthidwa.Mosiyana ndi izi, ma MCB safunikira kusinthidwa pambuyo paulendo.M'malo mwake, amatha kukonzanso mosavuta pambuyo pofufuza ndi kuthetsa kulephera kwa mizu, zomwe zimapangitsa kuti zikhale zosavuta komanso zotsika mtengo m'kupita kwanthawi.

6. Kusankha ndi Tsankho:

Mu machitidwe ovuta magetsi kumene angapoZithunzi za MCBszimayikidwa mumndandanda, malingaliro a kusankha ndi kusankhana amakhala ofunikira.Kusankha kumatanthawuza kuthekera kwa MCB kupatula dera lolakwika popanda kusokoneza dongosolo lonse.Kusiyanitsa, kumbali ina, kumatsimikizira kuti MCB yomwe ili pafupi kwambiri ndi zolakwika imayenda poyamba, potero kuchepetsa kusokonezeka pakuyika.Makhalidwewa amalola kuyankha kwachindunji ku kulephera kwa magetsi, kuonetsetsa kuti ntchito zofunikira zipitirire pamene akupeza ndi kuthetsa zomwe zimayambitsa kulephera.

Pomaliza:

Zowonongeka zazing'onomosakayika ndi gawo lofunikira la zomangamanga zamakono zamakono.Popereka chitetezo chowonjezereka komanso chachifupi, ma MCB amathandizira kuteteza zida, kuchepetsa kuwonongeka ndikuletsa moto wamagetsi.Kukula kwawo kophatikizika, kusavuta kugwiritsa ntchito, komanso kuthekera kokonzanso pambuyo paulendo zimawapangitsa kukhala otsika mtengo kusiyana ndi ma fusi achikhalidwe.Ndikofunikira kukumbukira kuti kukhazikitsa koyenera komanso kukonza nthawi zonse ma MCB ndikofunikira kuti pakhale njira yodalirika komanso yodalirika yamagetsi.Pomvetsetsa bwino ndikugwiritsa ntchito zodulira ma circuit ang'onoang'ono, titha kuwongolera chitetezo chonse ndikuyika kwamagetsi.
