CJM1 Mold Case Circuit Breaker Yopangidwa Mwamakonda 125A yokhala ndi MCCB Yophulika Kwambiri

Kufotokozera Kwachidule:

Kugwiritsa ntchito

Chotsekera ma circuit cha CJMM1 (chomwe chimatchedwanso chotsekera ma circuit) chingagwiritsidwe ntchito pa AC 50/60HZ power distribution network circuit yokhala ndi insulation voltage yovomerezeka ya 800V, voliyumu yovomerezeka ya 690V ndi current operation current yovomerezeka kuyambira 10A mpaka 630A, chimagwiritsidwa ntchito kugawa mphamvu ndikuletsa kuti zida zamagetsi ndi zamagetsi zisawonongeke chifukwa cha overload, short circuit, under voltage ndi zolakwika zina, chimagwiritsidwanso ntchito poyambitsa mota pafupipafupi komanso overload, short circuit ndi under voltage protection. Circuit breaker iyi ili ndi ubwino wa voliyumu yaying'ono, high breakability, short circuit (kapena noarcing) etc, ikhoza kukhala ndi zowonjezera monga alamu contact, shunt release, assistant contact etc, ndi chinthu chabwino kwambiri kwa ogwiritsa ntchito. Residual current circuit breaker ikhoza kuyikidwa molunjika (vertical installation) kapena kuyikidwa molunjika (horizontal installation). Chogulitsachi chikugwirizana ndi miyezo ya IEC60947-2 ndi Gb140482

ZIKWANGWANI ZOGWIRITSA NTCHITO ZOCHOTSERA MALANGIZO (MCCB)

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.

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.

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.
