Mtengo wogulira CJMM3-125 3P 125Amp Electrical Molded Case Circuit Breaker MCCB

Kufotokozera Kwachidule:

Chotsekera ma circuit cha CJMM3 chopangidwa ndi molded case (chomwe chimatchedwa circuit breaker) chili ndi makhalidwe ang'onoang'ono, mphamvu yayikulu yosweka, kufupika kwa ma arc, komanso choletsa kugwedezeka. Ndi choyenera ma network ogawa magetsi okhala ndi AC 50Hz, voteji yogwirira ntchito yoyesedwa ya 400V, komanso mphamvu yogwirira ntchito yoyesedwa mpaka 250A ndi pansi. Chimagwiritsidwa ntchito kugawa mphamvu zamagetsi ndikuteteza mizere ndi zida zamagetsi ku overload, short circuit ndi zolakwika zina. Chingagwiritsidwenso ntchito posintha ma circuit pafupipafupi komanso kuyambitsa ma mota pafupipafupi. Chotsekera ma circuit chingathe kuyikidwa molunjika (ndiko kuti, kuyikika molunjika) kapena molunjika (ndiko kuti, kuyikika molunjika).

Chogulitsachi chikugwirizana ndi IEC60947-2 ndi GB/T14048.2 “Zida zosinthira magetsi otsika ndi zida zowongolera Gawo 2: Zodulira ma Circuit”.

Zinthu Zogwirira Ntchito Ndi Kukhazikitsa

Kutalika kwa malo oikirako sikupitirira 2000m.
Kutentha kwa mpweya wozungulira;
Malire apamwamba a kutentha kwa mpweya wozungulira sapitirira +40°C;
Kutentha kwapakati pa mpweya wozungulira kwa maola 24 sikupitirira +35°C;
Malire otsika a kutentha kwa mpweya wozungulira si otsika kuposa -5°C;
Mkhalidwe wa mlengalenga:
Chinyezi cha mlengalenga sichidutsa 50% pamene kutentha kwakukulu kwa mlengalenga kuli +40°C. Chikhoza kukhala ndi chinyezi chambiri pa kutentha kochepa. Pamene kutentha kochepa kwa mwezi uliwonse kwa mwezi womwe uli ndi mvula yambiri sikupitirira +25°C, chinyezi cha mlengalenga sichidutsa +25°C. Chinyezi chapakati ndi 90%, poganizira za kuzizira kwa zinthu chifukwa cha kusintha kwa kutentha.
Mulingo wa kuipitsa: 3

Gulu la Zamalonda

Malinga ndi mphamvu yosweka ya choswera dera, imagawidwa m'magulu awa: mtundu wamba (mtundu wa S); mtundu wapamwamba wa b (mtundu wa H);
Malinga ndi njira yolumikizira mawaya ya choswerera mawaya: a. Kulumikiza mawaya patsogolo pa bolodi; b. Kulumikiza mawaya kumbuyo kwa bolodi; c. Mtundu wa pulagi; d. Mtundu wokokera;
Malinga ndi momwe ntchito ikuyendera: a. Kugwira ntchito mwachindunji ndi chogwirira; b. Kugwira ntchito potembenuza chogwirira; c. Kugwira ntchito kwamagetsi;
Malinga ndi chiwerengero cha mizati: mizati iwiri; mizati itatu; mizati inayi;
Malinga ndi zowonjezera: ma alamu olumikizirana, ma contact othandizira, kumasula shunt, kumasula undervoltage;
