MCCB 250A/400A/630A Selection Logic – Kafukufuku wa Anthu Electric RDM5 Series

250A, 400A ndi 630A ndi ma rating atatu omwe amagwiritsidwa ntchito kwambiri pa ma MCCB (molded case circuit breakers) pakugawa mphamvu zamafakitale, kugawa kwakukulu kwa nyumba ndi kuteteza zida.Mzere wa RDM5 wokhala ndi mphamvu zambiri zoswekaMonga chitsanzo chothandiza, nkhaniyi ikufotokoza njira yomveka bwino komanso yothandiza yosankha zinthu kuti ithandize mainjiniya ndi ogula kuzindikira mwachangu mtundu woyenera.

Mfundo Zosankha Zazikulu

1.Yoyesedwa panopa (Mu):Sankhani malinga ndi mphamvu yonse ya katundu yomwe yachulukitsidwa ndi 1.25, yofanana ndi mphamvu ya zida kapena ma circuits.

2.Kutha kusweka (Icu/Ics):Sankhani kutengera mphamvu yamagetsi yafupikitsa dongosolo kuti muwonetsetse kuti ikugwa bwino ngakhale pakakhala vuto.

3.Chiwerengero cha ndodo:2P ya ma circuits a gawo limodzi, 3P ya zida za magawo atatu, 4P ya makina a mawaya anayi a magawo atatu okhala ndi chitetezo chopanda malire.

4.Mtundu wa chitetezo:Chitetezo cha kugawa kapena chitetezo cha mota, chogwirizana ndi ma curve osiyanasiyana ogubuduzika.

5.Zowonjezera:Kuthamanga kwa shunt, kumasula mphamvu zamagetsi, kulumikizana ndi ma alarm kapena ma alarm kungawonjezedwe kuti muwongolere kutali komanso kuti muyankhe momwe zinthu zilili.

Milandu Yogwiritsira Ntchito ya RDM5 Series 250A/400A/630A

RDM5-250 (Chimango cha 250A)

● Mphamvu yamagetsi yoyesedwa: 100–250A

● Mphamvu yophwanya mphamvu (AC400V): Icu 35–50kA, Ics 25–35kA

● Ntchito zodziwika bwino: Kugawa nthambi m'mafakitale ang'onoang'ono ndi apakatikati, ma mota a magawo atatu (mafani, mapampu, ma compressor a mpweya), malo ocheperako ang'onoang'ono a PV box

● Malangizo osankha: Kufunika kwa 3P/4P yokhala ndi kutulutsidwa kwa maginito otenthetsera; mtundu woteteza injini pamakina onyamula katundu, wokhala ndi zolumikizira zothandizira/zochenjeza zomwe mungasankhe.

RDM5-400 (Chimango cha 400A)

● Mphamvu yamagetsi yoyesedwa: 200–400A

● Mphamvu yophwanya mphamvu (AC400V): Icu 50–70kA, Ics 35–50kA; Icu 20–25kA pa AC690V

● Ntchito zodziwika bwino: Kugawa kwakukulu m'ma workshop, malo osungira deta apakatikati, ma switch akuluakulu m'nyumba zamalonda

● Malangizo osankha: 3P/4P yovomerezeka yokhala ndi mtundu wa M (kusweka kwapakati); mtundu wa H-high-breaking version wa makina akuluakulu, yokhala ndi shunt/undervoltage remote protection ndi undervoltage protection.

RDM5-630 (Chimango cha 630A)

● Mphamvu yamagetsi yoyesedwa: 400–630A

● Mphamvu yophwanya mphamvu (AC400V): Icu 50–100kA, Ics 50–75kA; Icu 20–35kA pa AC690V

● Ntchito zodziwika bwino: Kulowa kwakukulu kwa zida zazikulu, kutuluka kwa magetsi ochepa m'malo ocheperako, mabwalo olumikizira mabasi a mafakitale

● Malangizo osankha: Kufunika kwa 3P/4P yokhala ndi mphamvu yotsika kwambiri ya mtundu wa H; ma contact othandizira/alamu ofunikira pa ma circuit ofunikira, omwe amapezeka m'mitundu yokhazikika komanso yotulutsa.

Chidule cha Kusankha Mwachangu

● 250A: Katundu wochepa ndi wapakati / kugawa nthambi → RDM5-250

● 400A: Kugawa kwakukulu kwapakati / chosinthira chachikulu cha nyumba → RDM5-400

● 630A: Ma circuits akuluakulu olowera / ofunikira kwambiri → RDM5-630

Kusankha kwathunthu komanso kogwirizana kungapangidwe m'magawo atatu:mphamvu yofanana → tsimikizirani mphamvu yosweka → sankhani mitengo ndi zowonjezera.
