RDB8DC-63 DC MCB

Chotsekereza cha DC chaching'ono cha RDB8DC-63 (chomwe chimatchedwa chotsekereza cha circuit), chomwe chimagwiritsidwa ntchito makamaka mu voteji yogwira ntchito ya DC yosapitirira 1000v, DC yamagetsi yosapitirira 63A, mphamvu yotsekereza ya circuit yochepa yosapitirira 10000A, chifukwa mzerewo sumalumikizidwa pafupipafupi, umasweka ndikusinthidwa. Ndi overload, ntchito yoteteza circuit yochepa.

Nthawi yomweyo, ili ndi gawo lamphamvu lothandizira, monga kulumikizana kothandizira, kulumikizana ndi chizindikiro cha alamu.

Chiyambi cha Zamalonda

Chotsekera ma circuit cha RDB8DC ndi chinthu chotsekera ma circuit chomwe chili ndi mphamvu zambiri zochepetsera mphamvu komanso chodalirika kwambiri, chomwe chapangidwira makampani olumikizirana. Chimagwiritsidwa ntchito makamaka pamakina ogawa magetsi monga makabati akuluakulu, makabati operekera magetsi, makabati ogawa, ndi makabati akunja mumakampani olumikizirana.

Mikhalidwe Yabwinobwino Yogwirira Ntchito ndi Mikhalidwe Yokhazikitsa

● Malire apamwamba a kutentha kwa mpweya wozungulira sayenera kupitirira +40℃, malire otsika sayenera kupitirira -5℃, ndipo kutentha kwapakati kwa maola 24 sikuyenera kupitirira +35°C;

● Malo okwezeka a malo oikirapo sayenera kupitirira 2000m;

● Chinyezi cha mlengalenga sichipitirira 50% pamene kutentha kwa mpweya kuli + 40℃, ndipo chinyezi chambiri chimatsika pa kutentha kochepa. Mwachitsanzo, 90% pa + 20℃. Njira zapadera ziyenera kutengedwa kuti madzi azisungunuka nthawi zina chifukwa cha kusintha kwa kutentha;

● Mukalumikiza mawaya, ndodo yolondola ya magetsi iyenera kulumikizidwa ku ndodo yabwino ya chopachikira magetsi, ndipo ndodo yoipa iyenera kulumikizidwa ku ndodo yoipa ya chopachikira magetsi. Kulumikizana kumbuyo sikuloledwa;

● Mlingo wa kuipitsa: Gawo 2;

● Mikhalidwe yokhazikitsira: Yoyikidwa pamalo opanda kugwedezeka kwakukulu, kugwedezeka, komanso pamalo opanda ngozi (kuphulika);

● Njira yokhazikitsira: Kugwiritsa ntchito njanji yoyikira ya TH35-7.5;

●Gulu loyika: KalasiⅡ, KalasiⅢ.

Moyo wamagetsi wa makina:

Chotsekera maginito pansi pa voteji yodziwika bwino, yatsani ndikuswa mphamvu yoyesedwa, mphamvu ndi 0.85 ~ 0.9, kuyesa kwa maginito ogwirira ntchito nthawi 120 pa ola limodzi (>32A) kapena nthawi 240 (≤32A), moyo wake wamakina ndi wamagetsi ndi nthawi 10000, moyo wamagetsi DC nthawi 1500.

Kapangidwe:

Chotsekera dera chimakhala ndi makina olumikizirana, makina ozimitsira arc, makina amagetsi, makina ogwetsa, makina ogwirira ntchito ndi nyumba.

Mfundo yogwirira ntchito:

Pansi pa mikhalidwe yabwinobwino yogwirira ntchito, kokerani njira yogwirira ntchito, panthawiyi kutulutsidwamakinawo atsekedwa, ndipo ma contact amphamvu komanso osasinthasintha amalumikizana kuti magetsi alumikizane.

Pamene chingwecho chadzaza kwambiri, pepala la bimetal la dongosolo la maginito limapanga kusintha, limakankhira loko kuti litulutse makinawo, ndikusuntha cholumikizira kuti chichotse ndikudula magetsi. Pamene dera lafupikitsidwa, dongosolo la maginito limakoka pakati pa chitsulo, ndipo ndodo ya pamwamba ya chitsulo imakankhira loko kuti makinawo atuluke, ndikumaliza ntchito yoteteza kusweka kwa dera losweka.
