MCCB

Mzere wa ELM1 Wopangidwa ndi Circuit Breaker (MCCB)

ELM1 MCCB ikutsatira IEC 60947-2, yomwe imapereka chitetezo cha mafakitale pa ntchito za 63A–1250A (mitundu: ELM1-160/250/400/630/1250) mu mawonekedwe a 3P/4P pole okhala ndi mizati ya A/D/N. Zinthu zofunika kwambiri ndi monga 690V insulation voltage, 400V operational voltage (mpaka 690V), ndi 100kA breakability yapamwamba (ELM1-1250). Imagwirizanitsa maulendo a thermal-magnetic ndi maulendo anzeru osankhidwa, chitetezo chotsimikizika cha inverse-time (≤20s pa 7.2In cold). Kapangidwe ka modular kamathandizira plug-in, motor-driven, kapena rotary-handle operation, ndi kukula kudzera mu shunt releases ndi ma contact othandizira. Yaing'ono, yosinthasintha, komanso yodalirika, imagwirizana ndi zosowa zosiyanasiyana za chitetezo cha mafakitale.

Kufotokozera kwa Zamalonda

ELM1 Series MCCB imagwiritsa ntchito ukadaulo wapamwamba wapadziko lonse lapansi, wogwirizana kwathunthu ndi IEC 60947-2, ndipo wapangidwa kuti ugawire mphamvu zamafakitale ndi kuteteza magalimoto. Kuphimba mafunde oyesedwa kuyambira 63A mpaka 1250A (mitundu: ELM1-160/200/400/630/800/1250) ndi ma configurations a 3P/4P (4P imaphatikizapo mitundu ya A/B/C/D N-pole), imatsimikizira kuti ikugwiritsidwa ntchito mosiyanasiyana. Zofunikira zazikulu ndi monga 690V rated insulation voltage, 400V AC operational voltage (yowonjezera mpaka 690V), ndi mphamvu yosweka mpaka 100kA (monga, ELM1-1250), kuthandizira ma grid a AC a 50/60Hz kuti azitha kusintha ma circuit ndikuwongolera magalimoto pafupipafupi.

Imaphatikiza mayunitsi oyendera maginito otentha komanso mayunitsi oyendera anzeru kuti atetezedwe ndi mphamvu yamagetsi yochulukirapo. Zinthu zofunika kwambiri zomwe zatsimikiziridwa zikuphatikiza kuchitapo kanthu nthawi yosinthira (monga, kugwedezeka mwachangu pa 7.2×In munthawi yozizira), mphamvu yamagetsi yosayenda yovomerezeka ya 1.05In (yogwira ≥2h), ndi malire ofunikira oyendera pa 1.30In. Miyeso yophwanya mphamvu ndi ma model: mitundu yoyambira (monga, ELM1-160) imapereka 50kA, pomwe ma model apamwamba (monga, ELM1-1250) amakwaniritsa 100kA@400V.

Mndandandawu uli ndi kapangidwe kake ka modular kwambiri, kothandizira ntchito za plug-in, motor-driven, ndi rotary-handle, komanso kuthekera kokulira kudzera mu shunt releases, undervoltage releases, ndi ma contact othandizira. Kapangidwe kake kakang'ono (kukula kwa matebulo pa parameter) kamakonza malo a panel, kothandizidwa ndi mayankho okhazikika a rail-mount. Yovomerezedwa padziko lonse lapansi, ELM1 Series ndi yokonzedwa bwino kuti igwiritsidwe ntchito pa switchboards zamafakitale ndi machitidwe ogawa mphamvu, kupereka magwiridwe antchito odalirika m'malo ovuta.

Kugwiritsa ntchito

Chotsekera ma circuit cha ELM1 series molded case ndi chimodzi mwa zinthu zomwe zimapangidwa ndikupangidwa pogwiritsa ntchito ukadaulo wapamwamba wapadziko lonse lapansi. Chimaperekedwa ndi voltage yodzitetezera yovomerezeka ya 690V ndipo chimagwiritsidwa ntchito pa circuit ya AC50/60Hz, voltage yoyendetsera yovomerezeka ya AC 400V (kapena pansi pake), current yoyendetsera yovomerezeka mpaka 1250A posintha ndi kuyambitsa ma mota pafupipafupi. Zogulitsazo zikugwirizana ndi muyezo wa IEC60947-2.
