Frame circuit breaker (ACB)

Frame circuit breaker inonziwo universal circuit breaker.Zvose zvikamu zvaro zvakaiswa mune insulated metal frame, iyo inowanzozaruka.Inogona kuve yakashongedzerwa nemhando dzakasiyana siyana.Izvo zviri nyore kutsiva vanobatika uye zvikamu, uye inonyanya kushandiswa mune main switch pamagumo emagetsi.Kune magetsi emagetsi, emagetsi uye akangwara kupfuura-ikozvino kuburitswa.Mutambo wedunhu une zvikamu zvina zvekudzivirira: kunonoka kwenguva refu, kunonoka kupfupi, pakarepo uye kukanganisa kwepasi.Iko kukosha kwekugadzika kwekudzivirira kwega kwega kunogadziriswa mukati mehumwe mutsara zvinoenderana nehoko rayo.
Iyo furemu yedunhu breaker inoshanda kune network yekugovera ine AC 50Hz, yakayerwa voltage ye380V uye 660V, uye yakayerwa ikozvino ye200a-6300a.Inonyanya kushandiswa kugovera simba remagetsi uye kudzivirira mitsara uye magetsi ekugadzirisa magetsi kubva pakuremerwa, undervoltage, short circuit, single-phase grounding uye zvimwe zvikanganiso.Iyo yedunhu inotyora ine akawanda akangwara ekudzivirira mabasa uye inogona kuwana yakasarudzika kuchengetedzwa.Mumamiriro ezvinhu akajairika, inogona kushandiswa kune isingawanzo chinja mutsara.Iyo yedunhu inotyora pazasi 1250A inogona kushandiswa kuchengetedza yakawandisa uye pfupi dunhu remota mune network ine AC 50Hz voltage ye380V.
Iyo furemu yemhando yedunhu breaker inowanzoiswa kune inobuda mutsara main switch, bhasi tie switch, hombe yekudyisa switch uye hombe yekudzora mota switch padivi re400V retransformer.

Yedu yeYuye brand frame circuit breaker yakavhara ese akatemerwa majeti, kusvika ku6300A, uye yapfuura CQC certification.

Basic characteristic parameters ye circuit breaker

(1) Rated kushanda voltage Ue

Iyo yakatemerwa yekushanda voltage inoreva zita remagetsi redunhu rinotyora, iro rinogona kushanda risingaperi pasi peyakatsanangurwa yakajairwa kushandiswa uye maitiro ekuita.
China inotaura kuti simba guru rekushanda inguva 1.15 yehuwandu hwemagetsi ehurongwa huri pamwero we 220kV uye pasi;Voltage level ye330kV zvichikwira i1.1 nguva dzevoltage yakayerwa seyakanyanya kushanda voltage.Iyo yedunhu inotyora inogona kuchengetedza insulation pasi peyakanyanya kushanda voltage yehurongwa, uye inogona kugadzira nekupwanya zvinoenderana nemamiriro akatsanangurwa.

(2) Yakatemerwa ikozvino (mu)

Rated ikozvino inoreva ikozvino kuti kusunungurwa kunogona kupfuura kwenguva yakareba kana ambient tembiricha iri pasi pe40 ℃.Kune wedunhu rinoputika nekugadziriswa kusunungurwa, ndiyo yakawanda ikozvino iyo kusunungurwa kunogona kupfuura kwenguva yakareba.
Kana tembiricha yepakati ichipfuura 40 ℃ asi isingakwire kupfuura 60 ℃, inotenderwa kudzikisa mutoro uye kushanda kwenguva yakareba.

(3) Yakawandisa kuburitsa ikozvino kuseta kukosha IR

Kana iyo yazvino ichipfuura iyo ikozvino yekumisikidza kukosha IR yekuburitswa, muparadzi wedunhu anononoka kutsika.Iyo zvakare inomiririra iyo yakanyanya ikozvino iyo inotyora wedunhu inogona kumira pasina kutsika.Ukoshi uhwu hunofanira kuva hukuru kupfuura huwandu hwemutoro hwazvino IB asi hushoma pane huwandu hwezvino iz hunobvumidzwa nemutsetse.
The thermal disconnect relay IR inogona kugadziriswa muhuwandu hwe 0.7-1.0in, asi kana midziyo yemagetsi ikashandiswa, chiyero chekugadzirisa chakakura, kazhinji 0.4-1.0in.Kune yedunhu inotyora ine isingachinjike overcurrent rwendo relay, IR = mukati.

(4) Short circuit kusunungurwa ikozvino kugadzirisa kukosha im

Iyo pfupi-circuit tripping relay (pakarepo kana kunonoka kunonoka) inoshandiswa kukurumidza kutsika chinotyora chedunhu kana yakakwira kukanganisa ikozvino, uye chikumbaridzo chayo chiri im.

(5) Yakatemerwa nguva pfupi inomira ICW yazvino

Inoreva kukosha kwazvino kunobvumidzwa kupfuura mukati menguva yakabvumiranwa.Iko kukosha kwezvino kuchapfuura nemuitisi mukati menguva yakabvumirana, uye muitisi haazokuvadzi nekuda kwekupisa.

(6) Kutyora simba

Kutyoka kwemupopori wedunhu kunoreva kugona kwemupopori wedunhu kuti acheke zvakachengeteka chikanganiso chiripo, izvo zvisingaite zvine chekuita neyakayerwa ikozvino.Iko kune 36ka, 50kA uye mamwe maitiro.Iyo inowanzo kupatsanurwa kuita muganho wepfupi-sekete yekutyora simba ICU uye inoshanda pfupi-yedunhu kutyora simba ICs.
