RCD, RCCB neRCBO: Ziva Musiyano
MaRCD, maRCCB uye maRCBO zvese zvishandiso zvemagetsi zvakakosha zvinoshandiswa kudzivirira njodzi yekuvhundutswa nemagetsi uye moto. Kunyange zvazvo zvichinzwika zvakafanana, mudziyo wega wega une basa rakasiyana uye une zvinhu zvawo zvakasiyana. Kunzwisisa mutsauko uripo pakati peizviRCD, RCCBuyeRCBOZvakakosha pakuona kuti magetsi akachengeteka munzvimbo dzekugara nedzemabhizinesi.
RCD, muchidimbu zvinoreva Residual Current Device, mudziyo wekuchengetedza wakagadzirirwa kubvisa simba nekukurumidza kana magetsi anobuda akaonekwa mudunhu. Kubuda kwemagetsi kunogona kuitika nekuda kwewaya dzisina kunaka, kutadza kushanda kwemidziyo, kana kusangana zvakananga nezvikamu zvipenyu. MaRCD akakosha pakudzivirira kuvhunduka kwemagetsi uye anowanzo shandiswa mudzimba, mumahofisi nemumaindasitiri.
RCCB (kureva Residual Current Circuit Breaker) imhando yeRCD yakagadzirirwa kudzivirira zvikanganiso zvepanyika. RCCB inotarisa kusawirirana kwezvino pakati pemaconductor ari mupenyu neasina kusimba uye inokanganisa circuit kana paine kubuda kwemvura pasi. Izvi zvinoita kuti maRCCB anyatsoshanda mukudzivirira kuvhunduka kwemagetsi kunokonzerwa nezvikanganiso zvemagetsi.
RCBO (residual current circuit breaker ine overcurrent protection) inosanganisa mabasa eRCCB ne miniature circuit breaker (MCB) mumudziyo mumwe chete. Pamusoro pekudzivirira ground fault, RCBO inopawo overcurrent protection, zvinoreva kuti inogona kuvhiringa circuit kana paine overload kana short circuit. Izvi zvinoita kuti RCBO dzishande zvakasiyana-siyana uye dzikwanise kushandiswa zvakasiyana-siyana, kusanganisira kuchengetedza macircuit ega ega mumabhodhi ekugovera.
Chimwe chezvinhu zvikuru zvakasiyana pakati pemidziyo iyi ikushandiswa kwayo uye mwero wekudzivirira kwainoita. MaRCD anowanzo shandiswa kudzivirira dunhu rese, nepo maRCCB nemaRCBO anowanzo shandiswa kudzivirira matunhu chaiwo kana michina yega yega. Pamusoro pezvo, maRCBO ane mukana wekuwedzera wekudzivirira mafambiro emagetsi zvakanyanya, zvichiita kuti ave mhinduro yakakwana yezvikanganiso zvakasiyana-siyana zvemagetsi.
Kana zvasvika pakuiswa, RCD, RCCB neRCBO zvakagadzirwa kuti zviiswe nenyanzvi yemagetsi. Kuiswa kwakakodzera kwakakosha kuti midziyo iyi ishande zvakanaka uye ipe dziviriro inodiwa. Kuongororwa nekugadzirisa nguva dzose kwakakoshawo kuti ive nechokwadi chekuti maRCD, maRCCB neRCBO anoramba achishanda sezvaitarisirwa.
Mukupfupisa, RCD, RCCB neRCBO zvinhu zvakakosha mukuchengetedza magetsi, uye chikamu chimwe nechimwe chine chinangwa chaicho chekudzivirira njodzi dzemagetsi nemoto. Kunzwisisa musiyano uripo pakati pemidziyo iyi kwakakosha pakusarudza dziviriro yakakodzera yekushandiswa kwakasiyana. Ingave kushandisa RCD yekudzivirira kwakajairika, RCCB yekudzivirira kukanganisa kwepasi, kana RCBO yekubatanidza dziviriro yekukanganisa kwepasi nekudzivirira kwemhepo yakawandisa, michina iyi inoita basa guru mukuona kuchengetedzeka kwemagetsi munzvimbo dzekugara nedzekutengeserana.
