Nzira dzekudzivirira kana uchishandisa RCBO

Chinopwanya magetsi cheResidual current circuit (RCBO) chine basa rekudzivirira magetsi zvakanyanya chinhu chakakosha pakuchengetedza masisitimu kana michina ine voltage shoma. Haingogone kudzivirira tsaona dzemagetsi chete uye kuchengetedza kuchengetedzeka kwemunhu, asiwo kutarisa mamiriro ekudzivirira pasi. Zvisinei, zvakakosha kunzwisisa kuti kuisa RCBO hakuvimbisi kuchengetedzeka. Tinofanira kutarisa pakudzivirira nekushandisa matanho akasiyana-siyana ehunyanzvi ekuchengetedza kuti tiwane kushandiswa kwemagetsi kwakachengeteka. RCBO ingori dziviriro yekuwedzera pakati pematanho ekutanga ekudzivirira. Kutarisira nekungwarira uye kuzivisa nekudzidzisa nezvekushandiswa kwemagetsi kwakachengeteka ndiyo vimbiso huru yekuchengetedza.

Chinhu chimwe chekurangarira pakushandisa RCBO ndechekuti inogona kungodzivirira muviri wemunhu chete kana tsaona yemagetsi yechikamu chimwe chete ikaitika. Kana muviri wemunhu wakadzivirirwa kubva panyika uye ukasangana nemitsara miviri yechikamu kana mutsetse mumwe wechikamu uye mutsetse mumwe wakamira, RCBO haizoshande. Izvi zvinoreva kuti haizodziviriri mumamiriro ezvinhu aya. Saka, vashandisi vanofanira kuziva nezvemuganhu uyu uye kutora matanho ekuwedzera ekuderedza njodzi dzetsaona dzakadaro.

Imwe nzira yekudzivirira inofanira kufungwa nezvayo ndeyekuputira circuit insulation iri kuseri kweRCBO mounting point. Zvakakosha kuti circuit ive yakaputirwa zvakanaka kubva pasi. Kana kuputira pasi kwakadzikira uye leakage current ikadarika kukosha kwakati, kazhinji kacho inenge 15mA, RCBO ichashanda yodzima magetsi. Izvi zvinosimbisa kukosha kwekuchengetedza kuputira kwakanaka kubva pasi kudzivirira zvikanganiso uye kuona kuti simba rinoshandiswa nemazvo. Kuputira kunofanirwa kuongororwa uye kuchengetedzwa nguva nenguva kudzivirira njodzi dzinogona kuitika.

Kana grid yemagetsi ine voltage shoma ichishandisa dziviriro yehierarchical, zvakakosha kushandisa RCBO yakanonoka kudzivirira yepamusoro. Nguva yekutyoka kwerudzi rweRCBO yekunonoka inofanira kunge yakareba kupfuura nguva yekushanda kwemudziviriri wepamusoro, kazhinji masekondi 0.1 kusvika 0.2. Kudzivirira uku kunovimbisa nzira yakakwana uye yakarongeka yekudzivirira mukati megrid. Nekutevera gwara iri, unogona kuderedza njodzi dzinogona kuitika uye kuvandudza kuchengetedzeka kwese kwesystem yako yemagetsi.

Muchidimbu, kunyange hazvo maRCBO akakosha pakudzivirira kuchengetedzeka kwemunhu uye kutarisa kuvharwa kwepasi mumasisitimu kana michina ine voltage shoma, zvakakoshawo kunzwisisa zvisingakwanisike uye kutora matanho anodiwa. Vashandisi vanofanirwa kutarisa pakudzivirira uye kushandisa matanho akasiyana-siyana ekuchengetedza kuti vave nechokwadi chekushandiswa kwemagetsi zvakachengeteka. Nekungotarisira kushandiswa kwemagetsi nokungwarira, kuchengetedza kuvharwa kwakanaka, uye kushandisa matanho ekudzivirira akarongwa ndipo patinogona kuwana vimbiso huru yekushandiswa kwemagetsi zvakachengeteka.
