Iyo yasara yazvino yedunhu breaker ine over-current chengetedzo (RCBO), ichokwadi imhando yedunhu rinopwanya rine leakage yekudzivirira basa.Iyo RCBO ine basa rekudzivirira kubva pakudonha, kuvhunduka kwemagetsi, kuwandisa uye pfupi pfupi.Iyo RCBO inogona kudzivirira kuitika kwetsaona yemagetsi uye kuita zviri pachena kudzivirira njodzi dzemoto dzinokonzerwa nekudonha kwemagetsi.MaRCBO akaiswa mumabhokisi edu akajairwa ekugovera edzimba kuti ave nechokwadi chekuchengetedzwa kwevanhu.RCBO imhando yekutyora iyo inosanganisa iyo MCB neRCD mashandiro mune imwechete breaker.MaRCBO anogona kuuya ari 1 danda, 1 + kwaakarerekera, mapango maviri kana mapango mana pamwe neamp rating kubva pa6A kusvika pa100 A, tripping curve B kana C, Breaking capacity 6K A kana 10K A, RCD mhando A, A & AC.
Iwe unofanirwa kushandisa RCBO nezvikonzero zvimwe chete zvatinokurudzira RCB - kukuchengetedza kubva kune tsaona yemagetsi uye kudzivirira moto wemagetsi.RCBO ine ese hunhu hweRCD ine overcurrent detector.
RCD imhando yedunhu rinopwanya rinogona kuvhura otomatiki kana paine chikanganiso chepasi.Iyi breaker yakagadzirirwa kuchengetedza njodzi dzetsaona electrocution uye moto unokonzerwa nekukanganisa kwepasi.Vagadziri vemagetsi vanoidana zvakare RCD (Residual Current Device) uye RCCB (Residual Current Circuit Breaker) Rudzi urwu rwekupwanya runogara ruine push-bhatani rekutyora bvunzo.Unogona kusarudza kubva pamapango maviri kana mana, Amp rating kubva pa25 A kusvika pa100 A, tripping curve B, Type A kana AC uye mA rating kubva pa30 kusvika pa100 mA.
Zvakanaka, zvingava zvakanaka kushandisa rudzi urwu rwekupwanya kudzivirira moto wetsaona uye electrocution.Chero nguva ipi neipi inopfuura nomumunhu inokosha kupfuura 30 mA inogona kufambisa mwoyo kupinda mu ventricular fibrillation (kana kuti kukanda mutinhimira wemwoyo kure)—chisakiso chinozivikanwa zvikurusa chorufu kupfurikidza nokuvhunduka kwemagetsi.RCD inomisa ikozvino mukati me25 kusvika ku40 milliseconds kusati kwaitika magetsi.Kusiyana neizvi, zvinojairika zvinotyora dunhu seMCB/MCCB (Miniature Circuit Breaker) kana mafuse anotyora chete kana yazvino iri mudunhu yakawandisa (zvinogona kuita zviuru zvenguva iyo RCD inodaira).Iyo diki yekuvuza ikozvino inoyerera kuburikidza nemuviri wemunhu inogona kukwana kukuuraya iwe.Zvakadaro, zvingangove zvisinga wedzere huwandu hwazvino hwakaringana fuse kana kuremedza wedunhu breaker uye kwete kukurumidza zvakakwana kuchengetedza hupenyu hwako.
Musiyano mukuru pakati peaya mabreaker breaker ndewekuti RCBO ine overcurrent detector.Panguva ino, unogona kunge uchifunga nezvekuti sei vachitengesa izvi zvakasiyana kana painenge paine musiyano mukuru pakati pavo?Wadii kutengesa mhando chete pamusika?Kuti unosarudza kushandisa RCBO kana RCD zvinoenderana nerudzi rwekuisa uye bhajeti.Semuyenzaniso, kana paine pasi panovuza mubhokisi rekugovera uchishandisa ese maRCBO breaker, chete chinotyora chine chikanganiso chinodzima.Nekudaro, rudzi urwu rwekugadzirisa mutengo wakakwira pane kushandisa RCD's.Kana bhajeti iri nyaya, unogona kugadzirisa zvitatu zveina MCB pasi pechishandiso chimwe chete chasara.Iwe unogona zvakare kuishandisa kune yakakosha maapplication senge jacuzzi kana inopisa tabhu yekumisikidza.Aya masisitimu anoda nekukurumidza uye kushoma activation ikozvino, kazhinji 10mA.Pakupedzisira, chero muputsi waunoda kushandisa zvinoenderana nedhizaini yako yekuchinja uye bhajeti.Nekudaro, kana iwe uchizogadzira kana kusimudzira switchboard yako kuti irambe iri mumirau uye ive nechokwadi chekuchengetedzwa kwemagetsi kwakanakisa kune ese emidziyo yemidziyo uye hupenyu hwevanhu, ita shuwa yekusangana neakavimbika magetsi nyanzvi.
AFDD iArc Fault Detection Device uye yakagadzirirwa kuona kuvepo kweane njodzi magetsi arcs uye kubvisa dunhu rakakanganisika.Arc Fault Detection Devices inoshanda ichishandisa microprocessor tekinoroji kuongorora waveform yemagetsi.Ivo vanoona chero masiginecha asina kujairika ayo angangoreva arc padunhu.Iyo AFDD ichabva yamisa simba kudunhu rakakanganiswa kudzivirira moto.Ivo vanonyanya kutarisisa kune arcs pane akajairwa edunhu edziviriro zvishandiso seMCBs & RBCOs.
