Product Model

CJ:Kodhi yebhizinesi
M:Mould kesi circuit breaker
1:Design Nhamba
□:Yakayerwa ikozvino yefuremu
□:Kutyora kugona hunhu kodhi/S inoreva yakajairika mhando (S inogona kusiiwa)H inoreva mhando yepamusoro

Cherechedzo: Kune mhando ina dzema neutral pole (N pole) yezvikamu zvina chigadzirwa. The neutral pole yerudzi A haina kugadzirwa ne over-current tripping element, inogara yakabatidzwa, uye haina kubatidzwa kana kudzimwa pamwe chete nezvimwe. matanda matatu.
Bango rakarerekera rerudzi B harina kurongedzerwa ne-over-current tripping element, uye rinobatidzwa kana kudzima pamwe chete nemamwe mapango matatu (i neutral pole inobatidzwa isati yadzimwa) yazvino, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (iyo isina kwairi danda inobatidzwa isati yadzimwa) Iyo isina kwayakarerekera yerudzi D inoshongedzerwa nepamusoro-ikozvino chinhu chekutsika, inogara ichibatidzwa uye haibatiswe. pamusoro kana kudzika pamwe chete nemamwe matanda matatu.

Hunhu hweMCCBs

MCCBsdzakagadzirwa nemabasa 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 rwendo mashandiro: Yakaumbwa kesi inopwanya madhiraivha anoshandisa inopisa-magineti rwendo nzira yekuona 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.
