circuit breakerinowanzo umbwa neyekusangana system, arc yekudzima system, inoshanda sisitimu, yerwendo unit, uye casing.
Basa remutsigiri wedunhu nderokucheka uye kubatanidza dunhu remutoro, uye kucheka dunhu rakashata, kuitira kudzivirira kuwedzera kwetsaona uye kuve nechokwadi chekushanda kwakachengeteka.Iyo yepamusoro-voltage circuit breaker inoda kutyora 1500V, uye ikozvino i1500-2000A arc, uye aya arcs anogona kutambanudzwa kusvika 2m uye achiri kuramba achipisa pasina kudzima.Naizvozvo, kudzimisa arc idambudziko rinofanirwa kugadziriswa kune yakakwira voltage circuit breakers.
Low-voltage circuit breakers, inozivikanwawo seotomatikimhepo inochinja, inogona kushandiswa kushandura nekudzima mitoro yedunhu, uye inogona kushandiswawo kudzora mota dzinotanga zvisingaite.Basa rayo rakaenzana nehuwandu hwemamwe kana ese emabasa ekuchinja banga, pamusoro-ikozvino relay, voltage kurasikirwa relay, thermal relay uye leakage protector.Icho chinhu chakakosha chekudzivirira chigadziro mu-low-voltage distribution distribution network.
Low-voltage circuit breakers ine akawanda ekudzivirira mabasa (yakawandisa,short circuit, undervoltage dziviriro, etc.), inogadziriswa kukosha kwekushandisa, yakakwirira kutyora kugona, kushanda kwakaringana, chengetedzo, nezvimwe, saka ivo vanoshandiswa zvakanyanya.Chimiro uye nheyo yekushanda Yakaderera-voltage circuit breaker inoumbwa nemashandiro ekushandisa, kutaurirana, zvidziviriro zvekudzivirira (zvakasiyana-siyana zvinobudiswa), arc yekudzima system nezvimwe zvakadaro.
Iko kushamwaridzana kukuru kwepasi-voltage circuit breaker yakavharwa nemaoko kana magetsi.Mushure mekunge iyo huru yekubata yavharwa, iyo yemahara yekutsika michina inovhara iyo huru yekubata munzvimbo yakavharwa.Iyo coil yekuburitswa kwepamusoro uye iyo thermal element ye thermal release yakabatana munhevedzano nemain circuit,uye iyo coil yekusunungurwa kwe undervoltage yakabatanidzwa mukuenderana neiyo magetsi.Kana dunhu rakapfupika-kutenderera kana kuremerwa zvakanyanya, iyo armature ye-over-ikozvino kuburitswa inodhonza mukati kuti iite yemahara yekutsika michina iite, uye iyo huru yekubata inobvisa dunhu guru.Kana dunhu richinge raremerwa, iyo inodziya yekupisa yekuburitsa inoburitsa kupisa kukotamisa bimetal sheet, ichisundira iyo yemahara yekuburitsa nzira kuti iite.Kana iyo yedunhu iri undervoltage, iyo armature ye undervoltage kuburitswa inoburitswa.Zvakare inobatidza iyo yemahara yekufamba michina.Iyo shunt kuburitswa inoshandiswa kuremote control.Panguva yekushanda kwakajairika, coil yayo inodzimwa.Kana kuremerwa kuri kudiwa, tinya bhatani rekutanga kuti upe simba coil.
