Kufunika ndi ntchito ya zopumira zazing'ono za dera

Mutu: Kufunika ndi ntchito yazodulira zazing'ono za dera

yambitsani:

Zothyola ma circuit breaker zazing'ono (MCBs)zimathandiza kwambiri pakuonetsetsa kuti makina amagetsi ndi otetezeka komanso odalirika. Zipangizozi zakhala gawo lofunika kwambiri pa kukhazikitsa magetsi amakono, zomwe zimagwiritsidwa ntchito popewa zolakwika zamagetsi ndikuchepetsa kuwonongeka komwe kungachitike. Nkhaniyi ikufotokoza kufunika ndi ntchito ya ma compact guards awa, kuwonetsa kufunika kwawo m'munda wa uinjiniya wamagetsi.

1. Kumvetsetsa ma miniature circuit breakers:

A chosokoneza dera chaching'ono, nthawi zambiri amafupikitsidwa ngatiMCB, ndi switch yamagetsi yokha yopangidwa kuti iteteze ma circuit amagetsi ku ma overcurrent ndi ma short circuit. Zipangizozi nthawi zambiri zimayikidwa m'ma switchboard, zida zamakasitomala ndi mabokosi a fuse ngati mzere woyamba wodzitetezera ku kulephera kwamagetsi.

2. Zinthu zazikulu ndi zigawo zake:

Ma MCBAmadziwika ndi kukula kwawo kochepa, nthawi zambiri amakhala ndi malo amodzi mkati mwa switchboard. Komabe, kukula kwawo kochepa sikuthandiza pa chitetezo chamagetsi. Zigawo zazikulu zaMCBkuphatikiza njira yosinthira, kulumikizana ndi njira yoyendera.

Makina osinthira magetsi amalola kuti wogwiritsa ntchito azitha kutsegula kapena kutseka magetsi pamanja. Komano, ma contacts ndi omwe amachititsa kuti magetsi azitha kuyenda bwino m'derali. Pomaliza, makina oyendera magetsi amazindikira magetsi ochulukirapo kapena afupikitsa magetsi ndipo amayambitsa magetsi.MCBkutsegula dera, motero kuteteza dongosolo.

3. Chitetezo cha pa mphepo yamphamvu:

Chimodzi mwa ntchito zazikulu zaMCBndi kuteteza kupitirira muyeso. Kupitirira muyeso kumachitika pamene mphamvu yamagetsi yambiri ikuyenda kudzera mu dera kuposa mphamvu yake yovomerezeka, zomwe zingayambitse kutentha kwambiri komanso kuwonongeka kwa zigawo zamagetsi.Ma MCBYankho ku vutoli mwa kusokoneza nthawi yomweyo magetsi, motero kupewa kutentha kwambiri ndikuchepetsa chiopsezo cha moto wamagetsi.

4. Chitetezo chafupikitsa:

Udindo wina wofunikira waMCBndi kuteteza kufupika kwa magetsi. Kufupika kwa magetsi kumachitika pamene kulumikizana mwangozi (nthawi zambiri chifukwa cha kulephera kwa waya kapena kulephera kwa insulation) kumapangitsa kuti magetsi ambiri aziyenda mu dera. Kufupika kwa magetsi kumatha kuwononga kwambiri chipangizocho ndipo kungayambitse moto. Nthawi yofulumira yoyankha ya MCB imachithandiza kuzindikira kufupika kwa magetsi ndikusokoneza dera lisanawonongeke kwambiri.

5. Kusiyana ndi fuse:

Ngakhale kuti ma MCB ndi ma fuse onsewa amateteza ku mavuto amagetsi, pali kusiyana kwakukulu pakati pa awiriwa. Ma fuse amakhala ndi mawaya opyapyala kapena zidutswa zachitsulo zomwe zimasungunuka pamene magetsi ambiri akuyenda, zomwe zimaswa dera. Fuse ikangophulika, imafunika kusinthidwa. Mosiyana ndi zimenezi, ma MCB safunika kusinthidwa atagwa. M'malo mwake, amatha kubwezeretsedwanso mosavuta pambuyo poti vuto la mizu lafufuzidwa ndikuthetsedwa, zomwe zimapangitsa kuti zikhale zosavuta komanso zotsika mtengo pakapita nthawi.

6. Kusankha ndi Tsankho:

Mu machitidwe ovuta amagetsi komwe pali zinthu zambiriMa MCBAkayikidwa motsatizana, malingaliro a kusankha ndi kusankhana amakhala ofunikira kwambiri. Kusankhana kumatanthauza kuthekera kwa MCB kupatula dera lolakwika popanda kusokoneza dongosolo lonse. Kusiyanitsa, kumbali ina, kumatsimikizira kuti MCB yomwe ili pafupi ndi cholakwika imapita koyamba, motero kuchepetsa kusokonezeka pakuyika. Makhalidwe amenewa amalola yankho lolunjika ku kulephera kwamagetsi, kuonetsetsa kuti ntchito zofunika zikupitilirabe pamene akupeza ndikuthana ndi chomwe chayambitsa kulephera.

Pomaliza:

Zosokoneza madera zazing'onoMosakayikira ndi gawo lofunika kwambiri pa zomangamanga zamagetsi zamakono. Mwa kupereka chitetezo cha overcurrent ndi short circuit, ma MCB amathandiza kuteteza zida, kuchepetsa kuwonongeka ndikuletsa moto wamagetsi. Kukula kwawo kochepa, kugwiritsa ntchito mosavuta, komanso kuthekera kobwezeretsanso pambuyo pa ulendo kumapangitsa kuti akhale njira yotsika mtengo m'malo mwa ma fuse achikhalidwe. Ndikofunikira kukumbukira kuti kuyika bwino ndi kusamalira nthawi zonse ma MCB ndikofunikira kuti makina amagetsi akhale ogwira ntchito komanso odalirika. Mwa kumvetsetsa bwino ndikugwiritsa ntchito ma miniature circuit breakers, titha kukonza chitetezo chonse komanso magwiridwe antchito amagetsi.
