Cjm3-400 3p Compact DIN Rail Molded Case Circuit Breaker MCCB

Kufotokozera Kwachidule:

Ma CJMM1 Series Molded case circuit breakers ndi zida zotetezera zamagetsi zomwe zimapangidwa kuti ziteteze dera lamagetsi ku magetsi ochulukirapo. Mphamvu yochulukirapo iyi imatha kuchitika chifukwa cha kuchuluka kwa magetsi kapena dera lalifupi. Ma circuit breaker amtunduwu amatha kugwiritsidwa ntchito m'ma voltage ndi ma frequency osiyanasiyana okhala ndi malire otsika komanso apamwamba a makonda osinthika. Kuphatikiza pa njira zopunthwa, ma MCCB amathanso kugwiritsidwa ntchito ngati ma switch odulira magetsi pamanja pakagwa ngozi kapena ntchito zokonza. Ma MCCB amayesedwa ndikuyesedwa kuti awone ngati pali magetsi ochulukirapo, kuchuluka kwa magetsi, komanso chitetezo cha zolakwika kuti atsimikizire kuti akugwira ntchito bwino m'malo onse ndi ntchito. Amagwira ntchito bwino ngati switch yobwezeretsanso magetsi kuti achotse magetsi ndikuchepetsa kuwonongeka komwe kumachitika chifukwa cha kuchuluka kwa magetsi, vuto la nthaka, dera lalifupi, kapena pamene magetsi apitirira malire a magetsi.

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
