250A, 400A na630A ndidzo nhatu dzinonyanya kushandiswa pakuongorora maMCCB (molded case circuit breakers) mukugovera magetsi mumaindasitiri, kugoverwa kwemagetsi muzvivakwa uye kudzivirira michina.RDM5 series ine simba guru reMCCBSemuenzaniso unoshanda, chinyorwa chino chinotsanangura nzira yakajeka uye inoshanda yekusarudza kuti ibatsire mainjiniya nevatengi kukurumidza kuona modhi chaiyo.
Nheyo dzeKusarudza Pfungwa
1.Rated current (In):Sarudza zvichienderana nehuwandu hwemagetsi akawedzerwa ne1.25, zvichienderana nesimba remuchina kana maseketi.
2.Kukwanisa kupwanya (Icu/Ics):Sarudza zvichibva pa "short-circuit current" yesystem kuti uve nechokwadi chekuti inogumburwa zvakanaka kana paine dambudziko.
3.Huwandu hwematanda:2P yedunhu rechikamu chimwe chete, 3P yemidziyo yechikamu chetatu, 4P yemasisitimu ewaya mana echikamu chetatu ane dziviriro yakatwasuka.
4.Rudzi rwekudzivirira:Dziviriro yekupararira kana yekudzivirira mota, zvinoenderana nemakomba akasiyana ekugumburwa.
5.Zvishongedzo:Kufamba kweshunt, kusunungurwa kweundervoltage, assistant kana alarm contacts zvinogona kuwedzerwa kuti zvikwanise kudzorwa kure uye kugadzirisa mamiriro ezvinhu.
Nyaya dzekushandisa dzeRDM5 Series 250A/400A/630A
RDM5-250 (Furemu ye250A)
● Rated current: 100–250A
● Kukwanisa kupwanya (AC400V): Icu 35–50kA, Ics 25–35kA
● Mashandisirwo akajairika: Kugoverwa kwemapazi mumafekitori madiki nepakati, mota dzine zvikamu zvitatu (mafeni, mapombi, macompressor emhepo), zviteshi zvidiki zvePV box-type
● Mazano ekusarudza: Kukoshesa 3P/4P ine thermal-magnetic release; shanduro yekudzivirira mota yekutakura mota, ine assistance/alarm contacts dzesarudzo.
RDM5-400 (Furemu ye400A)
● Rated current: 200–400A
● Kukwanisa kupwanya (AC400V): Icu 50–70kA, Ics 35–50kA; Icu 20–25kA paAC690V
● Mashandisirwo akajairika: Kugoverwa kukuru mumaworkshop, nzvimbo dzedata dzepakati nepakati, main switch muzvivakwa zvemabhizinesi
● Mazano ekusarudza: 3P/4P inokurudzirwa ine mhando yeM (yepakati nepakati); mhando yeH-high-breaking version yemasisitimu makuru, ine shunt/undervoltage release yekudzivirira kure uye undervoltage.
RDM5-630 (Furemu ye630A)
● Rated current: 400–630A
● Kukwanisa kupwanya (AC400V): Icu 50–100kA, Ics 50–75kA; Icu 20–35kA paAC690V
● Mashandisirwo akajairika: Kupinda kukuru kwemidziyo mikuru, kubuda kwemagetsi mashoma muzviteshi, maindasitiri ekubatanidza mabhazi
● Mazano ekusarudza: Kukoshesa 3P/4P ine H-type high-breaking capacity; zvakakosha zvekubatsira/alamu zvemacircuit akakosha, zvinowanikwa mumhando dzakagadziriswa uye dzinodhonzwa.
Pfupiso yeSarudzo Yekukurumidza
● 250A: Mitoro midiki nepakati / kugoverwa kwebazi → RDM5-250
● 400A: Kugoverwa kwepakati nepakati kwehukuru hwechivako / switch huru yechivako → RDM5-400
● 630A: Maturikirwo makuru anopinda/akakosha ane simba guru → RDM5-630
Sarudzo yakakwana uye inoenderana nezvinodiwa inogona kuitwa mumatanho matatu:enzanisa ratio yemagetsi → simbisa kugona kutyoka → sarudza mapango nezvishongedzo.
Nguva yekutumira: Kubvumbi-07-2026
