Cjm3e Series 400V 250AMP Chosinthika Chopangidwa ndi Circuit Breaker MCCB

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

Kodi MCCB ndi chiyani?

Ma molded case circuit breakers ndi zida zotetezera zamagetsi zomwe zimapangidwa kuti ziteteze dera lamagetsi ku magetsi ochulukirapo. Mphamvu yochulukirapo iyi imatha kuchitika chifukwa cha overload kapena short circuit. Ma molded case circuit breakers angagwiritsidwe ntchito m'ma voltage ndi ma frequency osiyanasiyana okhala ndi malire otsika komanso apamwamba a mayendedwe osinthika. Kuphatikiza pa njira zopunthwa, ma MCCB amathanso kugwiritsidwa ntchito ngati ma switch odulira manual pakagwa mwadzidzidzi kapena ntchito zokonza. Ma MCCB ndi ofanana ndipo amayesedwa kuti awone overcurrent, voltage surge, ndi error protection kuti atsimikizire kuti akugwira ntchito bwino m'malo onse ndi ntchito. Amagwira ntchito bwino ngati reset switch ya dera lamagetsi kuti adule magetsi ndikuchepetsa kuwonongeka komwe kumachitika chifukwa cha overload ya dera, ground fault, short circuit, kapena pamene current yapitirira malire a current.
