CJMM1E 1000V 250A 3P Electronic type MCCB Molded case circuit breaker Chithunzi Chodziwika

CJMM1E 1000V 250A 3P Electronic type MCCB Molded case circuit breaker yapamwamba kwambiri

Kufotokozera Kwachidule:

·Chotsekera magetsi cha CJM1E chamagetsi (chomwe chimatchedwa chotsekera magetsi), choyenera AC 50H2 kapena 60Hz), magetsi ake oteteza magetsi ndi 1000V, magetsi ogwiritsira ntchito ndi 690V ndi pansi pake, ndipo magetsi ogwiritsira ntchito ndi okwana 800A pakusintha kosachitika kawirikawiri m'mabwalo. Ndipo mota imagwiritsidwa ntchito poyambira kosachitika kawirikawiri. Chotsekera magetsi chimakhala ndi malire a nthawi yosinthira nthawi yayitali, malire a nthawi yosinthira nthawi yochepa, malire a nthawi yokhazikika yosinthira nthawi yochepa, chitetezo cha nthawi yochepa komanso yocheperako, chitetezo cha nthawi yotsalira (ngati mukufuna), ndi ntchito yoteteza kutaya kwa gawo (ngati mukufuna). Imatha kuteteza mizere ndi zida zamagetsi kuti zisawonongeke. Chotsekera magetsi chili ndi chitetezo chokwanira komanso cholondola, chomwe chingathandize kudalirika kwa magetsi ndikupewa kuzimitsa magetsi kosafunikira.

·Ma circuit breaker amagawidwa m'mitundu iwiri: M (mtundu wosweka kwambiri) ndi H (mtundu wosweka kwambiri) malinga ndi mphamvu yawo yosweka yochepa. Circuit breaker iyi ili ndi mawonekedwe ang'onoang'ono, mphamvu yosweka kwambiri, kutsetsereka kwafupi, komanso kuletsa kugwedezeka.

·Chotsekera dera chikhoza kuyikidwa molunjika (monga molunjika) kapena molunjika (monga molunjika).
·Chotsekera mawaya sichingabwezeretsedwe, kutanthauza kuti, 1, 3, ndi 5 zokha ndi zomwe zimaloledwa kulumikizidwa ku mawaya amagetsi ndipo 2, 4, ndi 6 ndizo zimaloledwa kulumikizidwa ku mawaya onyamula katundu.

Zinthu Zogwirira Ntchito Ndi Kukhazikitsa

·Kutalika: ≤2000m;
·Kutentha kozungulira: -5°C~+40°C;
·Zingathe kupirira mphamvu ya mpweya wonyowa;
·Imatha kupirira mphamvu ya kupopera mchere ndi utsi wa mafuta;
·Gulu lokhazikitsa la dera lalikulu la chosokoneza ma circuit ndi III, ndipo gulu lokhazikitsa la ma circuit ena othandizira ndi ma circuit owongolera ndi ll;
·Kutentha kwakukulu kukafika pa +40°C, chinyezi cha mpweya sichipitirira 50%. Chinyezi chambiri chimaloledwa pa chinyezi chochepa. Njira zapadera ziyenera kutengedwa kuti zithetse kuzizira kwa mpweya nthawi zina chifukwa cha kusintha kwa kutentha;
·Kupendekeka kwakukulu ndi 22.5°;
·Mu sing'anga yopanda ngozi yophulika, komanso komwe sing'angayo ilibe mpweya ndi fumbi loyendetsa lomwe lingathe kuwononga chitsulo ndikuwononga zoteteza kutentha;
·Kumalo komwe kulibe mvula kapena chipale chofewa.

Tetezani

·Kusintha kwa Ir1 kwa nthawi yayitali yogwira ntchito kungasinthidwe kuchokera pa mfundo 4 mpaka 10 malinga ndi mafunde osiyanasiyana a circuit breaker;
·Nthawi yayitali yochitapo kanthu t1 ikhoza kusinthidwa pa mfundo 4;
·Mphamvu ya Ir2 yocheperako-yochedwa pang'ono imatha kusinthidwa pa mfundo 10;
Kusintha kwa nthawi yochepa kwa t2, kusintha kwa mfundo 4 kulipo;
Mphamvu yogwira ntchito ya Ir3 yafupikitsa nthawi yomweyo imatha kusinthidwa pa mfundo 9 kapena 10;
Mphamvu ya Ir0 isanayambike alamu ikhoza kusinthidwa pa mfundo 7;
Malo oyesera, omwe amagwiritsidwa ntchito kuzindikira mtengo wamakono wa tripper yamagetsi;
Malangizo ogwirira ntchito yotulutsa zinthu zamagetsi;
Malangizo a alamu isanakwane;
Chizindikiro cha katundu wochulukirapo;
Batani la ulendo.
