Kuvharirwa kunze kweTagout kwekutarisira kuchengetedzeka

1. MichinaMidziyo inovhara michina zvakare rudzi rwemidziyo yekudzivirira, iyo inonyanya kushandiswa munzvimbo umo ma "low-voltage circuit breakers" maviri mu "double circuit" asingakwanise kuvharwa panguva imwe chete. Kana "A low-voltage circuit breaker" ne "B low-voltage circuit breaker" zvapedza "mechanical equipment interlocking", kana "B low-voltage circuit breaker" ichifanira kupa simba kana "A low-voltage circuit breaker" yavharwa, "A low-voltage circuit breaker" inofanira kutanga yabviswa, uye "B low-voltage circuit breaker" inodzimwa. Nenzira iyi, dambudziko rekukundikana kwe "wrong-phase short-circuit" nekuda kwekushandiswa zvisina kunaka kwe "double circuit" rinodzivirirwa.
Kubatana kwemidziyo yemakanika kunogonawo kukamurwa kuita tambo dzinobatana uye lever dzinobatana.
Nekufambira mberi kwemaitiro ehungwaru, masangano akawanda anofanira kuva nesimba rekuchengetedza michina nemidziyo. Kudiwa kwesimba rekuchengetedza michina kuri kuwedzerawo. Nokudaro, kuwedzera kune zvitoro zvemidziyo yemakanika zvakakosha, zvigadzirwa zvakawanda (kunyanya maswichi emagetsi maviri) zvine basa rezvitoro zvemagetsi.
2. Kuvhara magetsi zvinoreva kuti mumutsetse mukuru wekupinda nemutsetse wekupinda wakachengetwa, simba remagetsi rimwe chete rinodzimwa pamitsetse miviri yekupinda, uye rimwe rinodzimwa. Chinangwa ndechekuvimbisa kuvimbika kwenzira yekupa magetsi. Kana dunhu rimwe rekupa magetsi rikakundikana, rimwe dunhu rekupa magetsi rinogona kushandiswa nekukasika kuderedza dambudziko rekudzimwa kwemagetsi kwenguva refu nekuda kwekutadza kwedunhu. Midziyo yekubatanidza magetsi miviri-mu-imwe inogona kupedzisa kuchekwa ne laser otomatiki nekugadzirisa magetsi ekuchinja. Kazhinji, kana A low-voltage circuit breaker iri common switching power supply low-voltage circuit breaker, B low-voltage circuit breaker ibackup power low-voltage circuit breaker. Kana A low-voltage circuit breaker yakavharwa nekuda kwezvikanganiso zvakajairika, B low-voltage circuit breaker inovharwa otomatiki pasina kushanda nemaoko kuti ive nechokwadi chekuti magetsi anowanikwa zvakanaka. Midziyo yekubatanidza magetsi inoshandiswa munzvimbo huru uko magetsi asingabvumirwe kudzimwa.
