JCM1- Mlandu Wophwanyidwa Wozungulira
JCM1 mndandanda wa MoldedCase Circuit Breaker (yomwe tsopano ikutchedwa kuti circuit breaker) ndi mtundu watsopano wamagetsi opangidwa ndi kampani yathu ndiukadaulo wapamwamba wapadziko lonse lapansi komanso wopanga.
Chitetezo chochulukirachulukira, Chitetezo chozungulira pafupi, Pansi pa chitetezo chamagetsi
Ovoteledwa kutchinjiriza voteji upto 1000V, oyenera kutembenuka infrequent ndi galimoto kuyambira
Ovotera ntchito voteji mpaka 690V,
Ikupezeka mu 125A, 160A, 200A, 250A, 300A, 400A, 600A, 800A
Zogwirizana ndi IEC60947-2
Chiyambi:
Ma Molded Case Circuit Breakers (MCCB) ndi gawo lofunikira pamakina amagetsi, omwe amapereka chitetezo chochulukirapo komanso chitetezo chachifupi.Nthawi zambiri, ma MCCB amayikidwa mu board yayikulu yogawa magetsi pamalopo, zomwe zimapangitsa kuti makina azitsekedwa mosavuta pakafunika kutero.Ma MCCB amapezeka mumitundu yosiyanasiyana komanso mavoti, kutengera kukula kwamagetsi.
Mu bukhuli, tiwona zigawo ndi mawonekedwe a MCCB wamba, momwe amagwirira ntchito, ndi mitundu yomwe ilipo.Tikambirananso zaubwino wogwiritsa ntchito mtundu uwu wamagetsi pamakina anu amagetsi.
lts oveteredwa kutchinjiriza voteji ndi 1000V, amene ali oyenera kutembenuka infrequent ndi galimoto kuyambira mabwalo ndi AC 50 Hz, oveteredwa ntchito voteji mpaka 690V ndi oveteredwa panopa mpaka 800ACSDM1-800 popanda chitetezo galimoto).
Mtundu: IEC60947-1l
Chithunzi cha LEC60947-2low voltage circuit breaker
IEC60947-4 electromechanical circuit breakers ndi zoyambira zamagalimoto
IEC60947-5-1 zida zamagetsi zamagetsi zamagetsi
Zofunikira kwambiri
● Wowononga dera ali ndi katundu wochuluka, wozungulira pang'ono ndi chitetezo cha undervoltage, chomwe chingateteze chingwe ndi zipangizo zamagetsi kuti zisawonongeke.Panthawi imodzimodziyo, ikhoza kupereka chitetezo chokhudzana ndi anthu, komanso ingaperekenso chitetezo kwa nthawi yayitali yokhazikika yomwe singadziwike ndi chitetezo chamakono, chomwe chingayambitse ngozi ya moto.
● Wowononga dera ali ndi makhalidwe a voliyumu yaying'ono, kutalika kwapamwamba, kutsekemera kwafupipafupi ndi anti vibration
● Wowononga dera akhoza kuikidwa vertically ndi horizontally
● Chodulira chigawo sichingasinthidwe, ndiko kuti, 1, 3 ndi 5 okha ndi omwe amaloledwa ngati ma terminals amagetsi, ndipo 2, 4 ndi 6 ndi malo onyamula katundu.
● Wowononga dera akhoza kugawidwa kukhala mawaya akutsogolo, mawaya ammbuyo ndi mapulagi
Deta yaukadaulo

Kodi MCCB ndi chiyani?
MCCB ndi mawonekedwe achidule a Molded Case Circuit Breaker.Ndichitsanzo chodziwika bwino cha chipangizo chotetezera magetsi chomwe chimagwiritsidwa ntchito nthawi zambiri pamene katundu wamakono ndi wapamwamba kwambiri kuposa malire a kakang'ono ka circuit breaker.
MCCB imapereka chitetezo ku zolakwika zazifupi ndipo imagwiritsidwa ntchito posintha mabwalo.Itha kugwiritsidwa ntchito pazolinga zaposachedwa komanso zolakwika, pazolinga zochepa zapakhomo.Kuchuluka kwaposachedwa komanso kusweka kwakukulu mu Molded Case Circuit Breaker kumatanthauza kuti ndizoyeneranso pazifukwa zamakampani.
Kodi MCCB imagwira ntchito bwanji?
MCCB imagwiritsa ntchito chipangizo chozindikira kutentha (chinthu chotenthetsera) chokhala ndi chipangizo chamakono chamagetsi chamagetsi (maginito) kuti chipereke njira yodzitetezera komanso kudzipatula.Izi zimathandiza a MCCB kupereka:
Chitetezo chambiri,
Kutetezedwa kwa Zowonongeka kwa Magetsi motsutsana ndi mafunde amfupi, ndi
Kusintha kwa Magetsi kuti atseke.
Kodi pali kusiyana kotani pakati pa MCB ndi MCCB?
MCB ndi MCCB ndi zida zomwe zimagwiritsidwa ntchito poteteza dera.Zidazi zimapereka chitetezo ku mabwalo aposachedwa komanso afupi.Pali kusiyana kochepa pakati pa zida ziwirizi kupatula kuchuluka kwazomwe zidavotera.Kuchuluka komweku kwa MCB nthawi zambiri kumakhala pansi pa 125A, ndipo MCCB imapezeka mpaka pamlingo wa2500A.
