A molded case circuit breaker (MCCB)imhando yedunhu redunhu rinoshandiswa zvakanyanya kudzivirira magetsi mumaindasitiri nekutengesa zvivakwa nekuda kwekugona kwayo kupa yakavimbika uye yakachengeteka dziviriro kubva kune overcurrent, mapfupi maseketi uye kumwe kukanganisa kwemagetsi.Munyaya ino, tichaongorora zvakadzamaMCCBsuye kurukura maitiro avo, misimboti yekushanda, kuvaka, uye mashandisiro.
Hunhu hweMCCBs
MaMCCB akagadzirwa aine akati wandei anobatsira kuchengetedza masisitimu emagetsi nenzira yakachengeteka uye yakavimbika.Zvimwe zvakakosha zveMCCB zvinosanganisira:
- High breaking capacity:Molded case circuit breakersvanokwanisa kutyora macurrents kusvika kuzviuru zveamperes, zvichiita kuti ive yakanaka kune-high-power applications.
- Thermal-magnetic trip mechanism:Molded case circuit breakersshandisa thermal-magnetic rwendo mashandiro kuona uye kupindura kune overcurrent uye mapfupi maseketi.Thermal rwendo zvinhu zvinopindura zvakawandisa, nepo magineti ekufamba zvinhu achipindura kune mapfupi maseketi.
- Adjustable Rwendo Setting: MCCBs ane inogadzirika rwendo marongero, izvo zvinovabvumira kuti vagadzirwe padanho rakakodzera nokuda chikumbiro chinodiwa.
- Yakasiyana-siyana yehukuru hwemafuremu: MCCBs inowanikwa mumhando dzakasiyana-siyana, iyo inobvumira kuti ishandiswe mune zvakasiyana-siyana zvekushandisa.Kushanda nheyo ye molded case circuit breaker Nheyo yekushanda yeMCCB inobva pane thermal-magnetic tripping mechanism. .Thermal trip element inonzwa kupisa kunokonzerwa nekuyerera kweazvino mudunhu uye inokwenya chinotyora chedunhu kana ikozvino yadarika chiyero cherwendo.Iyo magnetic trip element inonzwa simba remagineti rinogadzirwa nekapfupi redunhu mudunhu, richigumbura chinotyora chedunhu ipapo ipapo.
- Iyo MCCB ine imba yepurasitiki yakaumbwa inogara iyo nzendo michina, vanobatika uye zvinotakura zvikamu.
- Iwo anobatika anogadzirwa neakanyanya conductive zvinhu semhangura, nepo nzira yerwendo ine bimetallic strip uye magineti coil.
Kushandiswa kweMCCB
MCCBs inowanzoshandiswa mumhando dzakasiyana-siyana dzakadai se:
- Simba rekugovera hurongwa
- Motor Control Center
- Industrial michina
- Transformers
- Seti jenareta
mukupedzisa
Molded case circuit breakers inovimbika zvakanyanya uye inoshanda michina yekudzivirira magetsi.Kuvaka kwavo uye hunhu hunovaita kuti vakwanise kushandiswa mumhando dzakasiyana dzekushandisa senge matransformer, magetsi ekugovera masisitimu, uye nzvimbo dzekudzora mota.Yavo yekupisa-magineti yerwendo dhizaini, yakakwira yekutyora simba uye inogadziriswa rwendo marongero anovaita sarudzo yakakurumbira yekudzivirira magetsi munzvimbo dzekutengesa uye dzeindasitiri.
