Gunyana 13, 2021, Ongorora musimboti wekushanda webhokisi-mhando yedunhu mabreaker
Circuit breakers anowanzo kuumbwa yekubatanidza sisitimu, arc yekudzima system, inoshanda sisitimu, rwendo unit, shell uye zvichingodaro.
Kana dunhu diki rikaitika, iyo magineti inogadzirwa neapo hombe (kazhinji gumi kusvika gumi nembiri) inokunda iyo reaction simba chitubu, iyo rwendo unit inodhonza mashandiro ekushandisa, uye switch inofamba ipapo ipapo.Kana yaremerwa, ikozvino inova yakakura, chizvarwa chekupisa chinowedzera, uye bimetal deforms kune imwe nhanho yekusundira nzira yekufamba (yakakura ikozvino, ipfupi nguva yekuita).
Iko kune mhando yemagetsi inoshandisa transformer kuunganidza ikozvino kwechikamu chimwe nechimwe uye inoienzanisa neiyo yakatarwa kukosha.Kana iyo yazvino isingaite, iyo microprocessor inotumira chiratidzo kuti iite yemagetsi rwendo unit kutyaira iyo inoshanda sisitimu.
Basa remutsigiri wedunhu nderokucheka uye kubatanidza dunhu remutoro, pamwe nekucheka kukanganisa kwedunhu, kudzivirira kuwedzera kwenjodzi uye kuve nechokwadi chekushanda kwakachengeteka.Iyo yepamusoro-voltage circuit breaker inoda kutyora 1500V, ikozvino 1500-2000A arc, aya arcs anogona kutambanudzwa kusvika ku2m uye achiri kuramba achipisa pasina kudzimwa.Naizvozvo, kudzima arc idambudziko rinofanirwa kugadziriswa ne-high-voltage circuit breakers.
Iyo musimboti wekuvhuvhuta kwearc uye kudzima arc inonyanya kutonhodza arc kunetesa kuparadzaniswa kwemafuta.Kune rumwe rutivi, arc inotambanudzwa nearc kusimbisa kubatanidzwa uye kupararira kwezvikamu zvinopomerwa, uye panguva imwechete, zvikamu zvinopomerwa mu arc gap zvinoputirwa kuti nokukurumidza kudzorera simba re dielectric repakati.
Low-voltage circuit breakers inonzi zvakare otomatiki mhepo switch, iyo inogona kushandiswa kubatanidza uye kutyora mitoro maseketi, uye inogona zvakare kushandiswa kudzora mota dzinotanga zvisingaite.Basa rayo rakaenzana nehuwandu hwemamwe kana ese emabasa ekuchinja kwebanga, overcurrent relays, voltage loss relays, thermal relays uye leakage protectors.Chinhu chakakosha chekudzivirira chemagetsi mumagetsi akaderera-voltage kugovera network.
Low-voltage circuit breakers ine akasiyana ekudzivirira mabasa (kuremedza, kupfupika, undervoltage dziviriro, nezvimwewo), inogadziriswa chiitiko kukosha, yakakwira yekutyora simba, kushanda kwakaringana, chengetedzo, nezvimwe, saka dzinoshandiswa zvakanyanya.Chimiro uye musimboti wekushanda Iyo yakaderera-voltage yedunhu breaker inoumbwa neanoshanda masisitimu, anobatika, ekudzivirira emidziyo (yakasiyana kuburitswa), arc yekudzima system, nezvimwe.
Iko kushamwaridzana kukuru kwepasi-voltage circuit breaker inoshandiswa nemaoko kana kuvharwa nemagetsi.Mushure mekunge iyo huru yekubata yakavharwa, iyo yemahara yekufamba michina inovhara iyo huru yekusangana munzvimbo yekuvhara.Iyo coil yekusunungurwa kwepamusoro uye chinhu chekushisa chekusunungurwa kwekushisa chakabatanidzwa mumutsara nedunhu guru, uye coil ye undervoltage release inobatanidzwa mukufanana nemagetsi.Kana dunhu rakapfupika-rakatenderedzwa kana kuremerwa zvakanyanya, iyo armature yekuburitsa yakawandisa inokwevera mukati, ichiita kuti yemahara yekutsika nzira ishande, uye iyo huru yekubata inobvisa iyo huru yedunhu.Kana iyo dunhu yaremerwa, iyo yekudziya chikamu cheiyo thermal rwendo unit inokotama bimetal uye kusunda nzira yemahara yekufamba.Kana dunhu riri pasi pe-voltage, iyo armature ye under-voltage release inosunungurwa.Iyo yemahara yekufamba michina inovhurwa zvakare.Iyo shunt kuburitswa inoshandiswa kuremote control.Panguva yekushanda kwakajairika, coil yayo inogurwa.Kana kuremerwa kunodiwa, tinya bhatani rekutanga kuti upe simba coil.
