Circuit breakers, iyo inowira muzvikamu zvitatu zvakafara.
Mhando yekutanga inonziair circuit breakeror air-insulated circuit breaker.Chiratidzo chefuremu Breaker ndichoACB, sezvo izwi rekuti Mhepo iri Circuit uye izwi rekuti Breaker iri Breaker.
Rudzi rwechipiri, runodanwamolded case circuit breaker, ndizvoMCCB;
Rudzi rwechitatu ndirwominiature circuit breaker, ane chiratidzoMCB.
Iyo yakayerwa ikozvino huwandu hweACB inobva 1250A kusvika 6300A, iyo yakawanda yakayerwa ikozvino chiyero;Iyo yakayerwa ikozvino huwandu hweMCCB inobva 10A kusvika 1600A, ine chiyero chemazuva ano chiri pakati.Iyo MCB ine diki diki reyero renji, kubva pa6A kusvika 63A, asi ndiyo huru yevanopwanya matunhu epamba.
Hazvina mhosva kuti ndeupi rudzi, kuvharidzira pakati pevanobatika mukati memugero wedunhu kunovimba nemhepo, icho zvakare chikonzero nei iyo MCB ichizivikanwa semhepo switch.
Sezvo kusungirirwa pakati pevanobatika mukati memugero wedunhu kunoenderana nemhepo, zvinodikanwa kuti isu tikurukure kuputsa maitiro emhepo, pamwe neruzivo rwekutanga rwearc.
2. Nezve arc
Tinoona arc segore remhepo inopisa.Mukati mearc, patembiricha inopfuura madhigirii 3 000, maerekitironi anobuda kubva mumaatomu kuti aite maioni asina kunaka, ayo anorasika zvekuti mamorekuru emhepo ese plasma, musanganiswa wemaerekitironi uye ionic gasi rakanaka.
3. Kuvhura kureba kwemutsigiri wedunhu
Frame circuit breaker ACB, iyo ipfupi chinhambwe pakati peinofamba yekubata uye iyo static yekubata inonzi yakavhurika kureba.
Nharaunda yekuvhura inoshandiswa kuve nechokwadi kuti mhepo pakati pematanho akazaruka haaitike kuparara kwemagetsi.
