Kunzwisisa Kukosha kweMiniature Circuit Breakers (MCBs) muKuchengetedza Kwemagetsi

Mundima yekuchengetedzwa kwemagetsi, madiki madiki edunhu (MCBs) kuita basa rakakosha mukudzivirira maseketi kubva pakuremerwa uye mapfupi maseketi. Midziyo iyi yakagadzirirwa kungovhiringa kuyerera kwemagetsi kana yaonekwa kuti pane chakashata, kudzivirira njodzi dzinogona kuitika senge moto kana magetsi. Nezvakawanda zvingasarudzwa zviripo zvinosanganisira AC DC Residual Current 1p 2P 3P 4P MCB, Residual Current Circuit Breaker, RCCB, RCBO neELCB, zvakakosha kuti tinzwisise kukosha kweMCB mukuona kuchengetedzwa kwemagetsi masisitimu.

MCBs dzakagadzirirwa kupa dziviriro yakavimbika mumhando dzakasiyana dzemagetsi ekushandisa, kubva pakugara kusvika kumaindasitiri nharaunda. Iwo anowanikwa mune akasiyana pole masisitimu, anosanganisira 1P, 2P, 3P uye 4P, kuti asangane nezvinodiwa chaizvo zvekumisikidzwa kwemagetsi kwakasiyana. Kungave kuchengetedza imwe-chikamu kana matatu-chikamu maseketi, MCB inopa mhinduro dzakasiyana-siyana kudzivirira masisitimu emagetsi kubva mukukanganisa.

Chimwe chezvinhu zvakakosha zveMCBs kugona kwavo kukurumidza kuona uye kupindura kune overcurrents uye mapfupi maseketi. Iyi mhinduro yekukurumidza inobatsira kuderedza njodzi yekukuvadzwa kwemidziyo yemagetsi uye wiring uye kuderedza mukana wemoto wemagetsi. Pamusoro pezvo, iyo MCB ine compact uye nzvimbo-yekuchengetedza dhizaini, ichiita kuti ive yakakodzera kuisirwa ine nzvimbo shoma.

Pamusoro pekudzivirira kwakanyanyisa, madiki edunhu anopwanya anopawo kuchengetedzwa kwekuvuza uye anowanzo kunzi asara emazuva ano mabreaker breakers (RCCB) kana kuvuza ikozvino inodzivirira michina (RCD). Midziyo iyi yakakosha pakuona uye kutyora dunhu kana kubuda kwemvura kwaonekwa, nokudaro kudzivirira njodzi yekuvhunduka kwemagetsi.

Paunenge uchisarudza iyo MCB yakakodzera kune chaiyo application, zvakakosha kuti titarise zvinhu zvakaita seyezvino chiyero, kutyora kugona uye mhando yedziviriro inodiwa. Kune akasiyana maMCB anowanikwa, anosanganisira maRCBOs (asara emazuva ano mabreaker ane overcurrent protection) uye ELCBs (leakage current circuit breaker), uye zvakakosha kuti usarudze MCB yakanyatsokodzera kuve nechokwadi chepamusoro-soro chekuchengetedzwa kwemagetsi.

Muchidimbu, MCBs chikamu chakakosha chekuchengetedzwa kwemagetsi, ichipa chengetedzo yakavimbika kubva kune overcurrent, short circuit uye leakage kukanganisa. Nesarudzo dzayo dzakasiyana siyana dzinosanganisira AC DC Residual Current 1p 2P 3P 4P MCB, RCCB, RCBO uye ELCB, MCB inopa mhinduro dzakasiyana uye dzinoshanda dzekudzivirira masisitimu emagetsi mumashandisirwo akasiyana siyana. Kunzwisisa kukosha kweMCBs kwakakosha kuve nechokwadi chekuchengetedza uye kuvimbika kwekuiswa kwemagetsi.
