KumvetsetsaRCD, RCBOndiRCCBZipangizo Zoyambira Zachitetezo Chamagetsi
Mu dziko la chitetezo chamagetsi, nthawi zambiri mumakumana ndi mawu monga RCD, RCBO ndi RCCB. Zipangizozi zimagwira ntchito yofunika kwambiri poteteza anthu ndi katundu ku mavuto amagetsi. Kumvetsetsa ntchito zawo, kusiyana kwawo ndi momwe amagwiritsidwira ntchito ndikofunikira kwa aliyense amene akugwira ntchito yokhazikitsa kapena kukonza magetsi.
Kodi RCD ndi chiyani?
RCD, kapena chipangizo chotsalira chamagetsi, ndi chipangizo chotetezera chomwe chimapangidwa kuti chiteteze kugwedezeka kwa magetsi ndi moto wamagetsi womwe umayambitsidwa ndi zolakwika za nthaka. Chimagwira ntchito poyang'anira nthawi zonse magetsi omwe akuyenda mu dera. Ngati chazindikira kusalingana pakati pa mawaya otentha ndi osalowerera (kusonyeza kuti magetsi akutuluka pansi), chimatsegula dera mkati mwa ma milliseconds. Kuyankha mwachangu kumeneku kungapulumutse miyoyo, zomwe zimapangitsa ma RCD kukhala gawo lofunikira kwambiri pamagetsi okhala m'nyumba ndi m'mabizinesi.
Ma RCD amagwiritsidwa ntchito kwambiri m'mabwalo omwe amapereka zida zakunja, zimbudzi ndi khitchini komwe chiopsezo cha kugwedezeka kwamagetsi chimakhala chachikulu. Amabwera m'njira zosiyanasiyana, kuphatikizapo ma RCD onyamulika kuti akhazikitsidwe kwakanthawi ndi ma RCD okhazikika omwe amayikidwa m'mayunitsi ogwiritsa ntchito.
Kodi RCCB ndi chiyani?
RCCB, kapena choletsa magetsi chotsalira, ndi mtundu wapadera wa RCD. Ntchito yayikulu ya RCCB ndi kuzindikira zolakwika za dziko lapansi ndikutsegula dera kuti apewe kugwedezeka kwa magetsi. Mosiyana ndi zoletsa zamagetsi zomwe zimateteza ku overloads ndi short circuit, RCCBs imangoyang'ana kwambiri pa kuteteza kutuluka kwa madzi padziko lapansi.
Ma RCCB amagwiritsidwa ntchito kwambiri m'magetsi okhala m'nyumba ndi m'mabizinesi kuti awonjezere chitetezo. Amapezeka m'ma rating osiyanasiyana, zomwe zimathandiza ogwiritsa ntchito kusankha chipangizo choyenera malinga ndi zofunikira pa kukhazikitsa kwawo magetsi. Ngakhale ma RCCB amapereka chitetezo chabwino kwambiri ku kugunda kwa magetsi, sapereka chitetezo ku overloads kapena short circuits, komwe ndi komwe zida zina zimagwira ntchito.
Kodi RCBO ndi chiyani?
RCBO, kapena chosinthira magetsi chomwe chili ndi chitetezo cha magetsi chopitilira muyeso, chimagwirizanitsa ntchito za RCD ndi chosinthira magetsi. Izi zikutanthauza kuti RCBO sikuti imateteza ku zolakwika za dziko lapansi, komanso ku overloads ndi short circuits. Ntchito ziwirizi zimapangitsa RCBO kukhala chisankho chosinthika pamakina amakono amagetsi.
Ma RCBO ndi othandiza kwambiri pamene malo ndi ochepa, chifukwa amatha kusintha RCD ndi chosokoneza ma circuit nthawi imodzi. Izi sizimangopangitsa kuti switchboard ikhale yosavuta, komanso zimawonjezera chitetezo mwa kupereka chitetezo chokwanira mu chipangizo chimodzi. Ndi abwino kwambiri pa nyumba zogona, nyumba zamalonda ndi ntchito zamafakitale.
Kusiyana Kwakukulu
Ngakhale ma RCD, ma RCCB ndi ma RCBO ali ndi ntchito zofanana pankhani ya chitetezo chamagetsi, ntchito zawo ndi zosiyana kwambiri:
- RCD: Imagwiritsidwa ntchito makamaka kuzindikira zolakwika za nthaka ndikudula dera kuti isagwedezeke ndi magetsi. Sipereka chitetezo chamagetsi chochulukirapo kapena chafupikitsa dera.
- RCCB: RCD yopangidwa mwapadera kuti izindikire zolakwika za dziko lapansi. Monga RCD, siiteteza ku zinthu zodzaza ndi zinthu zambiri kapena ma circuit afupiafupi.
- RCBO: Imaphatikiza magwiridwe antchito a RCD ndi chosokoneza ma circuit kuti iteteze ku zolakwika za nthaka ndi overloads/short circuits.
Mwachidule
Mwachidule, ma RCD, ma RCCB, ndi ma RCBO ndi zida zofunika kwambiri pa chitetezo chamagetsi. Kumvetsetsa ntchito zawo ndi kusiyana kwawo ndikofunikira kwambiri posankha chitetezo choyenera cha makina anu amagetsi. Kaya ndinu mwini nyumba, katswiri wamagetsi, kapena woyang'anira malo, kumvetsetsa zidazi kungakuthandizeni kupanga zisankho zotetezeka ndikupewa zoopsa zamagetsi. Mukamaganizira zoyika zidazi, nthawi zonse funsani katswiri wamagetsi woyenerera kuti muwonetsetse kuti malamulo ndi miyezo yakumaloko ikutsatira.
