Chotsalira chotsalira chaposachedwa chokhala ndi chitetezo chapano (RCBO), kwenikweni ndi mtundu wamtundu wamagetsi wokhala ndi ntchito yoteteza kutayikira.RCBO ili ndi ntchito yodzitchinjiriza kuti isatayike, kugwedezeka kwamagetsi, kuchulukirachulukira komanso kuzungulira kwakanthawi.RCBO imatha kuletsa kuchitika kwa ngozi zamagetsi komanso kukhala ndi zotsatira zodziwikiratu kuti mupewe ngozi zamoto zomwe zimachitika chifukwa cha kutayikira kwamagetsi.Ma RCBO amaikidwa m'mabokosi athu omwe timagawira m'nyumba kuti titsimikizire chitetezo cha anthu.RCBO ndi mtundu wosweka womwe umaphatikiza magwiridwe antchito a MCB ndi RCD mu chophwanya chimodzi.Ma RCBO amatha kubwera mumtengo umodzi, 1 + osalowerera ndale, mitengo iwiri kapena mitengo 4 komanso ma amp rating kuyambira 6A mpaka 100 A, piringupiringu B kapena C, Kuphwanya mphamvu 6K A kapena 10K A, RCD mtundu A, A & AC.
Muyenera kugwiritsa ntchito RCBO pazifukwa zomwezo zomwe tikupangira RCB - kuti ikupulumutseni ku electrocution mwangozi ndikuletsa moto wamagetsi.RCBO ili ndi mawonekedwe onse a RCD okhala ndi chowunikira chopitilira muyeso.
RCD ndi mtundu wa ophwanya dera omwe amatha kutsegula wosweka ngati dziko lapansi lalakwitsa.Chophulitsachi chidapangidwa kuti chiteteze kuopsa kwa electrocution mwangozi ndi moto wobwera chifukwa cha zolakwika zapadziko lapansi.Opanga magetsi amachitchanso RCD (Residual Current Device) ndi RCCB (Residual Current Circuit Breaker) Mtundu uwu wa breaker nthawi zonse umakhala ndi batani lopumira pamayeso ophwanya.Mutha kusankha kuchokera pamitengo iwiri kapena 4, Amp rating kuchokera 25 A mpaka 100 A, yokhotakhota B, Type A kapena AC ndi ma rating kuchokera 30 mpaka 100 mA.
Moyenera, zikanakhala bwino kugwiritsa ntchito mtundu uwu wa breaker kuteteza moto mwangozi ndi electrocution.Mkondo uliwonse womwe umadutsa mwa munthu wofunika kwambiri kuposa 30 mA ukhoza kuyendetsa mtima ku ventricular fibrillation (kapena kutaya kugunda kwa mtima)—chinthu chofala kwambiri cha imfa chifukwa cha kugwedezeka kwa magetsi.RCD imayimitsa zomwe zilipo mkati mwa 25 mpaka 40 milliseconds musanayambe kugwedezeka kwamagetsi.Mosiyana ndi izi, zowononga madera wamba monga MCB/MCCB (Miniature Circuit Breaker) kapena ma fuse amasweka pokhapokha mphamvu yamagetsi ikachulukira (zomwe zitha kukhala masauzande ambiri pomwe RCD imayankhira).Kutuluka pang'ono komwe kumadutsa mthupi la munthu kumatha kukuphani.Komabe, sizingachulukitse kuchuluka kwaposachedwa kokwanira kuti fuse kapena kudzaza chophwanyira dera komanso osathamanga kuti mupulumutse moyo wanu.
Kusiyana kwakukulu pakati pa ophwanya madera onsewa ndikuti RCBO ili ndi chowunikira chopitilira muyeso.Panthawiyi, mungakhale mukuganiza chifukwa chake amagulitsa izi mosiyana ngati zikuwoneka kuti pali kusiyana kwakukulu pakati pawo?Bwanji osagulitsa zachifundo pamsika?Kaya mumasankha kugwiritsa ntchito RCBO kapena RCD zimatengera mtundu wa kukhazikitsa ndi bajeti.Mwachitsanzo, pakakhala kutayikira kwapadziko lapansi m'bokosi logawa pogwiritsa ntchito zida zonse za RCBO, wosweka ndi chosinthira cholakwika ndiye amazimitsa.Komabe, mtengo wamasinthidwe amtunduwu ndiwokwera kuposa kugwiritsa ntchito ma RCD.Ngati bajeti ili ndi vuto, mutha kusintha ma MCB atatu mwa anayi pansi pa chipangizo chimodzi chotsalira.Mutha kuyigwiritsanso ntchito pazinthu zapadera monga jacuzzi kapena kuyika kwa tub otentha.Kuyika uku kumafuna kutsegulira kwachangu komanso kochepa, nthawi zambiri 10mA.Pamapeto pake, chophwanya chilichonse chomwe mukufuna kugwiritsa ntchito chimadalira kapangidwe kanu ka boardboard ndi bajeti.Komabe, ngati mukufuna kupanga kapena kukweza switchboard yanu kuti ikhale yokhazikika ndikuwonetsetsa chitetezo chabwino kwambiri chamagetsi pazida zonse ndi moyo wamunthu, onetsetsani kuti mwalumikizana ndi katswiri wodalirika wamagetsi.
AFDD ndi Arc Fault Detection Device ndipo idapangidwa kuti izindikire kupezeka kwa ma arcs owopsa amagetsi ndikudula dera lomwe lakhudzidwa.Arc Fault Detection Devices amagwiritsa ntchito ukadaulo wa microprocessor kusanthula mawonekedwe amagetsi.Amazindikira siginecha iliyonse yachilendo yomwe ingatanthauze arc padera.AFDD idzathetsa mphamvu nthawi yomweyo kudera lomwe lakhudzidwa kuti liteteze moto.Amakhudzidwa kwambiri ndi ma arcs kuposa zida wamba zoteteza dera monga MCBs & RBCOs.
