CJM1-250L/3300 250A 400V/690V China Factory Electric MCCB Molded Circuit Breaker

Chitsanzo cha Zamalonda

CJ: Kodi ya kampani
M: Chotsukira ma circuit cha bokosi lopangidwa
1: Nambala ya Kapangidwe
□:Mawonekedwe amakono a chimango
□:Kutha kusweka kwa mphamvu/khodi ya khalidwe/S imasonyeza mtundu wokhazikika (S ikhoza kuchotsedwa)H imasonyeza mtundu wapamwamba

Dziwani: Pali mitundu inayi ya pole yosagwirizana (pole ya N) ya zinthu zinayi. Pole yosagwirizana ya mtundu wa A ilibe chotchinga chamagetsi chopitirira muyeso, nthawi zonse imayatsidwa, ndipo simayatsidwa kapena kuzimitsidwa pamodzi ndi pole zina zitatu.
Mzati wa mtundu wa B wopanda mphamvu uli ndi chinthu chogwetsa mphamvu zambiri, ndipo umayatsidwa kapena kuzimitsidwa pamodzi ndi zipilala zina zitatu (mzati wa neutral umayatsidwa usanazimitsidwe) Mzati wa neutral wa mtundu wa C uli ndi chinthu chogwetsa mphamvu zambiri, ndipo umayatsidwa kapena kuzimitsidwa pamodzi ndi zipilala zina zitatu (mzati wa neutral umayatsidwa usanazimitsidwe) Mzati wa neutral wa mtundu wa D uli ndi chinthu chogwetsa mphamvu zambiri, nthawi zonse umayatsidwa ndipo suyatsidwa kapena kuzimitsidwa pamodzi ndi zipilala zina zitatu.

Kugawa

• Mwa kuswa mphamvu: mtundu wokhazikika (mtundu S) b wapamwamba mtundu wa kuswa mphamvu (mtundu H)
• Mwa njira yolumikizira: kulumikizana kwa bolodi lakutsogolo, kulumikizana kwa bolodi lakumbuyo la b, mtundu wa pulogalamu yowonjezera ya c
• Pogwiritsa ntchito njira yogwirira ntchito: ntchito yogwirira mwachindunji, ntchito yogwirira yozungulira b, ntchito yamagetsi c
• Chiwerengero cha ndodo: 1P, 2P, 3P, 4P
• Ndi chowonjezera: kukhudzana ndi alamu, kukhudzana kothandizira, kutulutsidwa kwa shunt, kutulutsidwa kwa mphamvu yamagetsi

Mkhalidwe Wabwinobwino wa Utumiki

• Kutalika kwa malo okhazikitsa sikuyenera kupitirira 2000m
• Kutentha kwa mpweya wozungulira
• Kutentha kwa mpweya wozungulira sikuyenera kupitirira +40℃
• Mtengo wapakati suyenera kupitirira +35℃ mkati mwa maola 24
• Kutentha kwa mpweya wozungulira sikuyenera kuchepera -5℃
• Mkhalidwe wa mlengalenga:
• 1. Chinyezi cha mpweya sichiyenera kupitirira 50% pa kutentha kwakukulu kwa +40℃, ndipo chikhoza kukhala kutentha kwakukulu pa kutentha kochepa, pamene kutentha kotsika kwambiri pamwezi wonyowa kwambiri sikupitirira 25℃ kungakhale 90%, chifukwa cha kusintha kwa kutentha, ziyenera kuganiziridwa.
• Mlingo wa kuipitsa ndi kalasi 3

Chizindikiro Chachikulu Chaukadaulo

Makhalidwe aMa MCCB

Ma MCCBZapangidwa ndi ntchito zingapo zomwe zimathandiza kuteteza makina amagetsi m'njira yotetezeka komanso yodalirika. Zina mwa zinthu zofunika kwambiri za MCCB ndi izi:

Kutha kuswa kwakukulu:Zophwanya ma circuit breakers zopangidwa ndi molded caseamatha kuswa mafunde mpaka ma ampere zikwizikwi, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito mphamvu zambiri.
Njira yoyendera maginito pogwiritsa ntchito kutentha: Ma circuit breaker opangidwa ndi molded case case amagwiritsa ntchito njira yoyendera maginito pogwiritsa ntchito kutentha kuti azindikire ndikuyankha ma overcurrent ndi short circuits. Ma thermal trip elements amayankha overloads, pomwe maginito trip elements amayankha ma short circuits.
Kusintha kwa Ulendo: Ma MCCB ali ndi kusintha kwa ulendo, zomwe zimathandiza kuti akhazikitsidwe pamlingo woyenera wa pulogalamu yomwe mukufuna.
Makulidwe osiyanasiyana a chimango: Ma MCCB amapezeka m'makulidwe osiyanasiyana a chimango, zomwe zimathandiza kuti agwiritsidwe ntchito m'njira zosiyanasiyana. Mfundo yogwirira ntchito ya chotsukira maginito chopangidwa ndi chitoliro chamagetsi Mfundo yogwirira ntchito ya MCCB imachokera pa njira yotchingira maginito yopangidwa ndi kutentha. Chinthu chotenthetsera chimamva kutentha komwe kumapangidwa ndi kuyenda kwa magetsi mu dera ndipo chimatchingira chotsukira maginito pamene magetsi apitirira chiwerengero cha maulendo. Chinthu chotenthetsera maginito chimamva mphamvu ya maginito yopangidwa ndi dera lalifupi mu dera, zomwe zimatchingira chotsukira maginito nthawi yomweyo. Kapangidwe ka chotsukira maginito chopangidwa ndi chitoliro chamagetsi ...
MCCB imakhala ndi nyumba yapulasitiki yopangidwa ndi pulasitiki yomwe imakhala ndi makina oyendera, zolumikizirana ndi zida zonyamulira magetsi.
Zolumikizirazo zimapangidwa ndi zinthu zoyendera mphamvu kwambiri monga mkuwa, pomwe njira yoyendera imakhala ndi mzere wa bimetallic ndi coil yamaginito.
