Monga tanena kale, RCBO imatsimikizira chitetezo ku mitundu iwiri yamagetsi.Choyamba mwa zolakwika izi ndi zotsalira zapano kapena kutayikira kwapadziko lapansi.Izi zithalzimachitika mwangozi kusweka kwa dera, komwe kumatha kuchitika chifukwa cha zolakwika zamawaya kapena ngozi za DIY (monga kudula chingwe mukamagwiritsa ntchito chodula chamagetsi).Ngati magetsi sanaphwanyidwe, ndiye kuti munthuyo adzakumana ndi vuto lamagetsi lomwe lingamuphe

Mtundu wina wa vuto lamagetsi ndi overcurrent, zomwe zingatenge mawonekedwe a overload or short circuit, Poyambirira.Derali lidzadzaza ndi zida zamagetsi zambiri, zomwe zimapangitsa kuti magetsi azitha kupitilira mphamvu ya chingwe.Kuzungulira kwachidule kumathanso kuchitika chifukwa cha kusakwanira kwa dera komanso kuchulukitsa kwamphamvu kwa amperage.Izi zimagwirizanitsidwa ndi chiopsezo chachikulu kuposa kulemetsa

Onani mitundu ya RCBO yomwe ikupezeka m'mitundu yosiyanasiyana pansipa.

RCBO vs. MCB

MCB siyingateteze ku zolakwika zapadziko lapansi, pomwe ma RCBO amatha kuteteza kugwedezeka kwamagetsi ndi kuwonongeka kwa dziko lapansi.

Ma MCB amayang'anira mayendedwe aposachedwa ndikusokoneza mabwalo panthawi yafupikitsa komanso mochulukira.Mosiyana ndi zimenezi, ma RCBO amayang'anitsitsa kayendedwe kameneka kudzera mumzere ndi kubwereranso mumzere wosalowerera.Komanso, ma RCBO amatha kusokoneza dera panthawi ya kutayikira kwa dziko lapansi, kuzungulira kwachidule, komanso kupitilira.

Mutha kugwiritsa ntchito ma MCB kuteteza ma air conditioners, mabwalo ounikira, ndi zida zina kupatula zida ndi zotenthetsera zomwe zimalumikizana mwachindunji ndi madzi.Mosiyana ndi izi, mutha kugwiritsa ntchito RCBO kuti muteteze ku kugwedezeka kwamagetsi.Chifukwa chake, mutha kuyigwiritsa ntchito kusokoneza mphamvu, zoyambira mphamvu, zotenthetsera madzi komwe mutha kukhala ndi vuto lamagetsi.

Mutha kusankha ma MCB potengera kuchuluka kwafupipafupi komwe kulipo ndikuyiyika yomwe imatha kusokoneza ndikupindika kwaulendo.Ma RCBO akuphatikiza kuphatikiza kwa RCBO ndi MCB.Mutha kuzisankha potengera kuchuluka kwanthawi yayitali komanso kunyamula, ndipo zimatha kupindika, kusokoneza, ndikupereka kutayikira kwakanthawi.

MCB imatha kupereka chitetezo ku mabwalo amfupi komanso kupitilira apo, pomwe RCBO imatha kuteteza ku mafunde akutuluka padziko lapansi, mabwalo amfupi, ndi ma overcurrent.

RCBO ndiyabwino chifukwa imatha kuteteza kumadzi akuchulukira padziko lapansi, mabwalo amfupi, ndi ma overcurrent, pomwe MCB imangoteteza kumayendedwe amfupi komanso kupitilira apo.Komanso, RCBO imatha kuteteza kugwedezeka kwamagetsi ndi zolakwika zapadziko lapansi, koma ma MCB sangatero.

Kodi RCBO mungagwiritse ntchito liti?

Mutha kugwiritsa ntchito RCBO kuti muteteze ku kugwedezeka kwamagetsi.Makamaka, mutha kugwiritsa ntchito kusokoneza zitsulo zamagetsi ndi chotenthetsera chamadzi, komwe mungapeze mwayi wamagetsi amagetsi.

Mawu akuti RCBO akuyimira Residual Current Breaker yokhala ndi chitetezo cha Over Current.Ma RCBO amaphatikiza chitetezo ku mafunde akuchulukira padziko lapansi komanso motsutsana ndi ma overcurrents (ochulukira kapena ozungulira).Ntchito yawo imatha kumveka ngati ya RCD (Residual Current Device) potengera chitetezo chochulukirapo komanso chachifupi, ndipo izi ndi zoona.Ndiye pali kusiyana kotani pakati pa RCD ndi RCBO?

RCBO idapangidwa kuti iziphatikiza magwiridwe antchito a MCB ndi RCD kuti zitsimikizire kuti mabwalo amagetsi akuyenda bwino.Ma MCD amagwiritsidwa ntchito popereka chitetezo ku ma-currents ndipo ma RCD amapangidwa kuti azindikire kutayikira kwapadziko lapansi.Pomwe chipangizo cha RCBO chimagwiritsidwa ntchito popereka chitetezo pakuchulukirachulukira, mabwalo amfupi, ndi mafunde akutuluka padziko lapansi.

Cholinga cha zida za RCBO ndikupereka chitetezo pamabwalo amagetsi kuti zitsimikizire kuti magetsi akuyenda bwino.Ngati mphamvu yapano ili yosalinganika, ndi ntchito ya RCBO kudula/kuswa dera kuti mupewe kuwonongeka ndi zoopsa zomwe zingachitike pagawo lamagetsi kapena kwa wogwiritsa ntchito.

Monga momwe dzinalo likusonyezera, ma RCBO adapangidwa kuti aziteteza ku mitundu iwiri ya zolakwika.Zolakwika ziwiri zomwe zimachitika mkati mwamagetsi ndi Earth Leakage ndi Over-Currents.

Kutulutsa kwapadziko lapansi kumachitika pakaduka mwangozi kuzungulira komwe kungayambitse ngozi monga kugwedezeka kwamagetsi.Kutayikira kwapadziko lapansi kumachitika nthawi zambiri chifukwa chosayika bwino, ma waya osakwanira kapena ntchito za DIY.

Pali mitundu iwiri yosiyana ya over-current.Fomu yoyamba imakhala yodzaza kwambiri yomwe imachitika pakakhala magetsi ambiri pa dera limodzi.Kudzaza dera lamagetsi kumawonjezera mphamvu yolangizidwa ndipo kumatha kuwononga zida zamagetsi ndi zida zamagetsi zomwe zingayambitse zoopsa monga kugwedezeka kwamagetsi, moto, ngakhale kuphulika.

Fomu yachiwiri ndi dera lalifupi.Dongosolo lalifupi limachitika pakakhala kulumikizana kwachilendo pakati pa maulumikizidwe awiri amagetsi pamagetsi osiyanasiyana.Izi zingayambitse kuwonongeka kwa dera kuphatikizapo kutentha kwambiri kapena moto womwe ungakhalepo.Monga tanena kale, ma RCD amagwiritsidwa ntchito kuteteza kutayikira kwapadziko lapansi ndipo ma MCB amagwiritsidwa ntchito kuteteza kupitilira apo.Pomwe ma RCBO adapangidwa kuti aziteteza kutayikira kwapadziko lapansi komanso mafunde opitilira muyeso.

Ma RCBO ali ndi maubwino ambiri pogwiritsa ntchito ma RCD ndi ma MCB omwe akuphatikiza izi:

1.RCBOs adapangidwa ngati chipangizo cha "All in One".Chipangizochi chimapereka chitetezo cha MCB ndi RCD zomwe zikutanthauza kuti palibe chifukwa chogula padera.

2.RCBOs amatha kuzindikira zolakwika mkati mwa dera ndipo amatha kuteteza zoopsa za magetsi monga kugwedezeka kwa magetsi.

3.RCBO idzathyola magetsi ozungulira magetsi pamene dera liri lopanda malire kuti achepetse kugwedezeka kwa magetsi ndikuletsa kuwonongeka kwa matabwa a ogula.Kuphatikiza apo, ma RCBO amayendera dera limodzi.

4.RCBOs ali ndi nthawi yochepa yoika.Komabe, akulangizidwa kuti katswiri wamagetsi akhazikitse RCBO kuti atsimikizire kuyika bwino komanso kotetezeka

5.RCBOs imathandizira kuyesa kotetezeka ndi kukonza zida zamagetsi

6.Chidacho chimagwiritsidwa ntchito kuchepetsa kuyenda kosafunikira.

7.RCBOs amagwiritsidwa ntchito kulimbikitsa chitetezo cha chipangizo chamagetsi, wogwiritsa ntchito, ndi katundu wawo.

RCBO ya magawo atatu ndi chida chapadera chachitetezo chomwe chimagwiritsidwa ntchito pamakina amagetsi a magawo atatu, okhazikika pazamalonda ndi mafakitale.Zipangizozi zimasunga zabwino zachitetezo cha RCBO yokhazikika, zomwe zimateteza kugwedezeka kwamagetsi chifukwa cha kutayikira komwe kulipo komanso zochitika zambiri zomwe zitha kuyambitsa moto wamagetsi.Kuphatikiza apo, ma RCBO a magawo atatu adapangidwa kuti azitha kuthana ndi zovuta zamagawo atatu amagetsi, kuwapangitsa kukhala ofunikira pakuteteza zida ndi ogwira ntchito m'malo omwe machitidwewa akugwiritsidwa ntchito.
