Mutu: Kumvetsetsa Kufunika kwaZophulitsira Dera la Kutayikira kwa Dziko Lapansi
yambitsani
M'dziko lamakono lomwe chitetezo chamagetsi ndichofunika kwambiri,ma residual current circuit breakers (RCCBs)zimathandiza kwambiri kuteteza chitetezo cha miyoyo ya anthu ndi katundu wawo. Ngakhale kuti ambiri sadziwa bwino mawuwa,Ma RCCBndi gawo lofunikira kwambiri pa dongosolo lililonse lamagetsi. Nkhaniyi ikufuna kufotokoza bwino kufunika kwa ma residual current circuit breakers, ntchito yawo ndi ubwino wawo poteteza ma electroinstallation.
Ndime 1: Kodi chiganizo ndi chiyanichoswa dera chotayira madzi padziko lapansi?
Chotsukira ma circuit cha residual current, chomwe chimadziwika kutiRCCB, ndi chipangizo chamagetsi chopangidwa kuti chiteteze anthu ndi malo ogwiritsira ntchito magetsi ku ngozi zamagetsi komanso moto zomwe zimachitika chifukwa cha kutayikira kwa magetsi. Mwachidule, chipangizo chamagetsiRCCBImayang'anira mphamvu yamagetsi mu dera ndipo imasokoneza dera ngati yapeza kuti mphamvu yamagetsi ilibe mphamvu. Kusalingana kumeneku kungayambitsidwe ndi mphamvu yamagetsi yotuluka, zolakwika pa insulation, kapena kukhudzana mwachindunji ndi ma conductor amoyo.
Ndime 2: Kodi munthu amachita bwanjintchito yotsegula dera lotayira madzi padziko lapansi?
Zotsekereza magetsi otayikira zili ndi ma transformer amagetsi omwe amayesa magetsi mosalekeza kudzera mu ma conductor amoyo ndi osalowerera. Nthawi iliyonse pakakhala kusiyana pakati pa magetsi olowera ndi magetsi obwerera, zimasonyeza kuti pali kutayikira kapena vuto.RCCBimazindikira kusiyana kumeneku ndipo imasokoneza mwachangu dera, ndikudula mphamvu kuti isawonongekenso.
Ndime yachitatu: ubwino wa zophulitsa dera lotayikira
Kuyika chotseka ma circuit breaker cha earth leakage kuli ndi ubwino wambiri pankhani ya chitetezo ndi chitetezo. Choyamba, zimatha kuchepetsa kwambiri chiopsezo cha kugwedezeka kwa magetsi mwa kuzindikira kusalinganika pang'ono mu circuit ndikusokoneza magetsi pakapita nthawi. Chachiwiri,Ma RCCBndizofunikira kwambiri poteteza ku moto woyambitsidwa ndi mavuto amagetsi, chifukwa zimayankha mwachangu ku magetsi osasinthasintha, zomwe zimachepetsa kuthekera kwa kutentha kwambiri ndi kupindika.
Kuphatikiza apo, zotchingira magetsi zomwe zimatuluka zimatha kutseka magetsi mwachangu ngati magetsi atuluka kapena alephera, zomwe zimapangitsa kuti zipangizo ndi zida zina zitetezeke. Pochita izi, zida zamtengo wapatali zitha kutetezedwa ku kuwonongeka komwe kungachitike, zomwe zimapangitsa kuti ndalama zisamawonongeke komanso kuti zikhale ndi moyo wautali.
Ndime 4: Mitundu ya zopumira zapadziko lapansi
Pali mitundu iwiri ikuluikulu yaMa RCCB: Mtundu wa AC ndi Mtundu A. Ma RCCB amtundu wa AC amagwiritsidwa ntchito kwambiri m'malo okhala anthu kuti ateteze ku mafunde osinthasintha a sinusoidal. Ma RCCB awa ndi abwino kwambiri poteteza ku magwero ofala a kutayikira monga kusokoneza mawaya, mawaya owonongeka, ndi kulephera kwa zida.
Koma ma RCCB amtundu wa A ndi apamwamba kwambiri ndipo amapereka chitetezo chowonjezera mwa kuphatikiza ma current osinthasintha ndi ma pulsating direct current (DC). Ma RCCB amenewa nthawi zambiri amaikidwa m'mapulogalamu aukadaulo monga zipatala, malo opangira mafakitale komanso komwe zipangizo zamagetsi zodziwika bwino zimagwiritsidwa ntchito. Ma RCCB amtundu wa A amateteza mokwanira ku zolakwika za AC ndi DC popanda malo oti agwirizane.
Ndime 5: Kufunika kwa nthawi zonseRCCBkuyesa ndi kukonza
Ngakhale kuti ma residual current circuit breakers ndi ofunikira kwambiri pa chitetezo cha magetsi, ndikofunikiranso kumvetsetsa kufunika koyesa ndi kukonza nthawi zonse. Monga chipangizo china chilichonse chamagetsi,Ma RCCBukalamba pakapita nthawi, zomwe zimachepetsa mphamvu zawo kapena kulephera. Chifukwa chake, kuyezetsa ndi kukonza nthawi zonse kuyenera kukonzedwa kuti zitsimikizire kutiRCCBikugwira ntchito bwino kwambiri ndipo imaletsa ngozi zilizonse zamagetsi.
Ndime 6: Mapeto
Pomaliza, ma residual current circuit breakers ndi gawo lofunika kwambiri la machitidwe amagetsi amakono, omwe amapereka chitetezo chofunikira ku kugunda kwa magetsi ndi zoopsa zamoto. RCCB imatha kuzindikira kusalingana kwa magetsi ndikusokoneza magetsi pakapita nthawi, zomwe zingathandize kwambiri chitetezo cha kugwiritsa ntchito magetsi ndikuteteza moyo ndi katundu. Mwa kuyika ndalama mu ma RCCB apamwamba, kusankha mtundu woyenera pa ntchito iliyonse, ndikuchita mayeso ndi kukonza nthawi zonse, tonsefe titha kupanga malo otetezeka amagetsi kwa ife tokha komanso mibadwo yamtsogolo.
