Kodi MCCB ndi chiyani?

MCCB -kuumbidwa mlandu circuit breaker- ndi chipangizo chodzitchinjiriza chotsika kwambiri chomwe chimangodula chigawo chikazindikira kuchuluka kwazinthu kapena kufupikitsa. Mosiyana ndi fusesi, ikhoza kukhazikitsidwanso ndikugwiritsidwanso ntchito mukayenda. Mkati mwa chikwama chopangidwa, makina oyendera maginito otenthetsera amagwira ntchito ziwiri: chinthu chotenthetsera chimayankha pakuchulukira kosalekeza, pomwe chinthu cha maginito chimachita nthawi yomweyo pakawonongeka kwakanthawi kochepa. Zotsatira zake ndi chitetezo chomwe chimagwirizana ndi momwe katundu weniweni wamagetsi amachitira.

Nthawi yosankha MCCB: zodyetsa zazikulu zomwe zikubwera, mapanelo ogawa magawo atatu, mabwalo akulu amagalimoto, kapena malo aliwonse omwe njira yachidule imaposa zomwe MCB ingasokoneze.

MCB ikakwanira: madera omaliza okhala ndi katundu wocheperako komanso zolakwika zochepa - matabwa okhalamo, zowunikira ndi zozungulira.

250A three-pole MCCB

Momwe mungasankhire MCCB yoyenera

Zovoteledwa pano (Mu)

1. - kufanana ndi katundu wopitirira, ndi kulola headroom poyambira mafunde a Motors.

Kuphwanya mphamvu (Icu / Ics)

2. - ayenera kukhala apamwamba kuposa oyembekezera yochepa dera panopa pa unsembe mfundo. Kukwera kwa zolakwikazo, ndipamwamba kwambiri Icu yomwe mukufuna.

Mitengo

3. - 3P kwa machitidwe a magawo atatu, 4P kumene osalowerera nawonso amafunikira kuchotsedwa.

Mavoti amagetsi

4. - fufuzani oveteredwa voteji ntchito (Ue), kutchinjiriza voteji (Ui) ndi zikhumbo kupirira (Uimp) motsutsana dongosolo.

Miyezo ndi certification

5. - Kutsata kwa IEC/EN 60947-2 ndi chizindikiritso cha CE ndizoyambira pama projekiti apadziko lonse lapansi.

Kugwiritsa ntchito

6. - chitetezo chamoto, kugawa mphamvu ndi kukhazikitsa kwa mafakitale kungafunike mavoti osiyanasiyana ndi mawonekedwe aulendo.

Momwe 250A MCCB yodziwika bwino imawonekera:

Kuti mupange konkireyi, ganizirani za DAM3-250 kuchokera ku C · DADA Electric - 250A MCCB yamitengo itatu yomwe ikuwonetsa zomwe muyenera kuyang'ana m'gulu la chipangizochi:

Kusintha kwa 3P

● yokhala ndi 250A yovomerezeka panopa (In), yoyenera matabwa ogawa magawo atatu

Mavoti amagetsi:

● 690V~; Ue AC400/415V, Ui 750V, Uimp 8kV

Kuphwanya mphamvu mpaka 50kA

● — Icu ya 18 / 25 / 36 / 50 kA pamitundu yosiyanasiyana ya B / C / N / S, kuti oyika agwirizane ndi zolakwika pamanetiweki osiyanasiyana

IEC/EN 60947-2 ndi GB 14048.2 kutsatira

● CE yolembedwa, yokhala ndi cholumikizira chowoneka bwino cha ON/OFF kuti chiwonekere

● Kumangidwira kugawa mphamvu, kuteteza magalimoto ndi ntchito zamakampani

Lingaliro lachidziwitso ichi: 250A, 3-pole frame yokhala ndi 50kA kalasi yothyola mphamvu imakhudza zofunikira zambiri za omanga mapanelo ndi makontrakitala - kuchokera pamabodi akuluakulu ogawa kupita ku mabwalo odyetsera magalimoto - pomwe mitundu ingapo ya Icu imakupatsani mwayi wokwera mtengo motsutsana ndi zolakwika zenizeni.

Malingaliro osankhidwa

● Pamagawo omaliza mpaka ~ 125A okhala ndi zolakwika zochepa, MCB ndiyosankha mwachuma.

● Kuti mugawire kwambiri, chitetezo chagalimoto ndi ma switchgear a mafakitale, sankhani MCCB yokhala ndi mphamvu yosweka kuposa yomwe ikuyembekezeka kukhazikitsidwa.

● Mukakayikira, kalasi imodzi ikukwera pa kusweka mphamvu: kusiyana kwa mtengo ndi kochepa, pamene malire a chitetezo angakhale kusiyana pakati pa vuto laling'ono ndi kuzima kwakukulu.

Mafunso omwe amafunsidwa pafupipafupi

Q: Kodi MCCB ndi chiyani?

A: Akuumbidwa mlandu circuit breakerndi chipangizo chodzitchinjiriza chotsika-voltage chomwe chimatha kulumikiza dera pakuchulukira kapena kufupikitsa, chopangidwira mafunde okwera komanso milingo yolakwika kuposa chowotcha chaching'ono.

Q: Kodi Icu ikutanthauza chiyani pa MCCB?

A: Icu ndiye mphamvu yayikulu kwambiri yosweka - vuto lalikulu lomwe wosweka amatha kusokoneza. Ics ndiye mphamvu yothyola ntchito, mulingo womwe imatha kusokoneza mobwerezabwereza ndikugwirabe ntchito.

Q: Kodi ndingasankhe bwanji mphamvu yosweka ya MCCB yanga?

A: Sankhani mlingo wa Icu wapamwamba kuposa womwe ukuyembekezeka kukhala wamfupi-fupi pakali pano poyikapo. Mabodi ogawa omwe ali ndi ma thiransifoma okwera kwambiri kapena ma feed aatali akumafakitale nthawi zambiri amafunikira zida zamakalasi 36-50kA.

Q: Kodi DAM3-250 MCCB ndi chiyani?

A: DAM3-250 ndi 250A yopangidwa ndi matabwa atatu kuchokera ku C·DADA Electric, yovotera mpaka 690V ndi mphamvu yosweka mpaka 50kA, yogawa mphamvu, chitetezo chamoto ndi ntchito zamakampani.
