Circuit breaker sarudzo

1.mudunhu rekuvhenekesa kuitira kuti uderedze mutengo weprojekiti, kazhinji sarudza 1P wedunhu wedunhu, inoda kutarisisa kune yepamusoro wedunhu breaker inofanirwa kunge iine leakage rwendo basa, inofanira kugura simba repamusoro;

2. Kugadziriswa kwemagetsi kuitira kudzivirira mutsara wehupenyu uye mutsara we zero wakabatanidzwa kune tsaona (apo mutsara unorarama uye mutsara we zero wakabatanidzwa kune 1P bvisa mutsara we zero uye hauna kubvisa mutsara wehupenyu), inogona kushandiswa. 1P + N pfupi yedunhu mudziyo, iyo inowanzonzi DPN wedunhu breaker.

3. Nokuda kweimba inoputika yehukuru hwakafanana, pane musiyano pakati pe1P ne1P + N, iyo yekare ine simba repamusoro rekuputsa kupfuura iyo yekupedzisira pasi pemamiriro emutsaona wedunhu pfupi.Nokudaro, zvinokurudzirwa kushandisa 2P circuit breaker kune inonyanya kukosha dunhu uye nguva dzose kugadzirisa uye kushanda kwedunhu mupurojekiti, asi mari yacho yakakwirira.

Mukuwedzera: 1P, 2P ye-single-phase, 3P, 4P yezvikamu zvitatu.

Kana iri zero kudzivirira, chete 1P, 3P inogona kushandiswa;Kana iri nzvimbo yekudzivirira, zviri nani kushandisa 2P, 4P.

1P + N: mudziviriri anongoiswa pamutsetse wechikamu, uye mutsara wechikamu unobviswa panguva imwe chete kana chiito chatorwa.
