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;

Chiyeso cha kuswa kwa dera

Zizindikiro zotsutsana ndi nthawi yosweka ya kutulutsidwa kwa magetsi ochulukirapo a choswa magetsi chogawa pamene mitengo yonse yapatsidwa mphamvu nthawi imodzi

Makhalidwe otsutsana a nthawi yosweka ya kutulutsidwa kwa circuit breaker kuti ateteze injini pamene mitengo yonse yapatsidwa mphamvu nthawi imodzi

Makhalidwe ogwirira ntchito nthawi yomweyo a choswa dera chogawa magetsi amaikidwa pa 10In±20%, ndipo makhalidwe ogwirira ntchito nthawi yomweyo a choswa dera choteteza injini amaikidwa pa 12In±20%.

Kusiyana pakati pa M1 series ndi M3 series MCCB

Ma Molded case circuit breakers (MCCB) ndi zinthu zofunika kwambiri mu makina amagetsi, zomwe zimapereka chitetezo cha overload ndi short-circuit. Ponena za ma MCCB, M1 series ndi M3 series ndi njira ziwiri zodziwika bwino, iliyonse ili ndi mawonekedwe ake komanso kuthekera kwake. Kumvetsetsa kusiyana pakati pa mndandanda uwu kungathandize ogwiritsa ntchito kupanga zisankho zolondola posankha MCCB yomwe ikugwirizana bwino ndi zosowa zawo.

M1 Series MCCB yapangidwa kuti igwiritsidwe ntchito pomwe magwiridwe antchito oyenera ndi okwanira. Imapereka chitetezo chodalirika pamabwalo ndi zida, yokhala ndi zinthu monga kusintha kwa kutentha ndi maginito. Yoyenera kugwiritsidwa ntchito m'mafakitale ndi m'mabizinesi osiyanasiyana, M1 Series imapereka chitetezo chotsika mtengo popanda kuwononga khalidwe ndi chitetezo.

Koma ma M3 series molded case circuit breakers, apangidwa kuti akwaniritse zosowa za makina amagetsi ovuta komanso ofunikira kwambiri. Amapereka chitetezo chapamwamba kuphatikizapo kutulutsidwa kwa kutentha kosinthika ndi kutulutsidwa kwa maginito, komanso njira zina zotetezera zolakwika za nthaka ndi kulumikizana. M3 Series ndi yabwino kwambiri pa ntchito zomwe zimafuna magwiridwe antchito abwino komanso kusinthasintha, monga malo akuluakulu amafakitale ndi kukhazikitsa zomangamanga zofunika kwambiri.

Chimodzi mwa kusiyana kwakukulu pakati pa ma MCCB a M1 ndi M3 ndi magwiridwe antchito awo. M1 Series imapereka chitetezo chodalirika pa ntchito zokhazikika, pomwe M3 Series imapereka zinthu zapamwamba komanso zosankha m'malo ovuta kwambiri. Kuphatikiza apo, M3 series ikhoza kukhala ndi mphamvu yayikulu yothyola kuposa M1 series ndipo imatha kuthyola ma current amphamvu kwambiri.

Mwachidule, kusankha ma M1 ndi M3 series molded case circuit breakers kumadalira zofunikira za makina amagetsi ogwirizana nawo. M1 Series imapereka chitetezo chotsika mtengo pa ntchito zokhazikika, pomwe M3 Series imapereka zinthu zapamwamba komanso kuthekera kokhazikitsa zovuta komanso zofunika kwambiri. Kumvetsetsa kusiyana pakati pa mndandanda uwu ndikofunikira kwambiri posankha chosinthira cha makina oyenera kwambiri kuti muwonetsetse kuti makina anu amagetsi ndi otetezeka komanso odalirika.
