Chii chinonzi air circuit breaker uye ndeipi basa rayo guru

1. Kuchinja kwemhepo
An air switch, inozivikanwawo seanair circuit breaker, imhando yecircuit breaker.Iyo switch yemagetsi inodzima otomatiki chete kana iripo mudunhu inodarika yakayerwa voltage.Iyo mhepo inoshandura chinhu chakakosha zvikuru chemagetsi mukamuri yekugovera network uye simba rekudhonza system.Inobatanidza kutonga uye kuchengetedza kwakasiyana-siyana.Pamusoro pekubata uye kubvisa dhizaini yemagetsi, inogona kukonzera kukanganisa-pfupi-mudunhu remagetsi kana midziyo yemagetsi.Yakanyanya kuomesesa uye pasi-voltage dziviriro inogona zvakare kushandiswa kune infrequent motor kushanda.
1. Nheyo
Kana mutsara wekugovera uchiwanzoremerwa, kunyangwe iyo yakawandisa yazvino haigone kugadzira iyo electromagnetic buckle chinzvimbo, ichaita kuti iyo inopisa element iburitse imwe huwandu hwekupisa, izvo zvinozoita kuti bimetallic sheet rikotamire kumusoro kana yapisa, uye tsvimbo sunungura hoko nekukiya, kutyora iyo main contact ,cheka simba.Kana dunhu diki kana kurema kwakanyanya kuri kuitika mumutsara wekugovera, ikozvino inodarika kukosha kwazvino kwerwendo rwepakarepo, uye kuburitswa kwemagetsi kunogadzira simba rekusveta rakakwana kukwezva armature uye kurova lever, kuitira kuti hoko itenderere kumusoro. kutenderedza chigaro cheshaft uye kukiya kunoburitswa.Vhura, kukiya kunobvisa matatu makuru ekubatika pasi pechiito cheiyo reaction spring, uye kucheka magetsi.
2. Basa guru
Mumamiriro ezvinhu akajairika, armature yekusunungurwa kwepamusoro inosunungurwa;kana kukanganisa kwakakomba kana kukanganisa-pfupi kunoitika, iyo coil yakabatana munhevedzano nedunhu guru inoburitsa simba remagetsi kukwezva kukwezva armature pasi uye kuvhura yekiyi hoko.Vhura the main contact.An undervoltage release inoshanda zvakasiyana.Kana iyo voltage yekushanda yakajairika, iyo electromagnetic kukwezva inokwezva armature, uye iyo huru yekubata inogona kuvharwa.Kamwe chete magetsi ekushanda akadzikiswa zvakanyanya kana simba rikagurwa, iyo armature inoburitswa uye makuru ekubatika anovhurwa.Kana magetsi emagetsi adzokera kune zvakajairika, inofanirwa kuvharwa zvakare isati yashanda, iyo inoziva kudzivirira kurasikirwa kwemagetsi.
