MCCB 250A/400A/630A Inzira yo Guhitamo – Inyigo y'Urukurikirane rw'Amashanyarazi ya RDM5 ku Baturage

250A, 400A na 630A ni byo bipimo bitatu bikunze gukoreshwa cyane kuri MCCB (ibice bikoresha imiyoboro y'amashanyarazi) mu gukwirakwiza ingufu z'amashanyarazi mu nganda, gukwirakwiza ingufu z'inyubako no kurinda ibikoresho.MCCB ifite ubushobozi bwo gukoresha RDM5 seriesUrugero rufatika, iyi nkuru isobanura uburyo bwo guhitamo ibintu busobanutse neza kandi bufatika kugira ngo ifashe injeniyeri n'abaguzi kumenya vuba uburyo bukwiye.

Amahame y'ingenzi yo guhitamo

1.Ingano y'amashanyarazi (Muri):Hitamo ukurikije umuvuduko w'umuzigo wose ukubye 1.25, uhuze imbaraga z'ibikoresho cyangwa imiyoboro.

2.Ubushobozi bwo kumenagura (Icu/Ics):Hitamo ukurikije umuyoboro wa "short-circuit" wa sisitemu kugira ngo urebe ko ugenda neza mu gihe hari ikibazo.

3.Umubare w'inkingi:2P ku miyoboro y'amashanyarazi ifite icyiciro kimwe, 3P ku bikoresho bifite icyiciro cya gatatu, 4P ku miyoboro y'amashanyarazi ifite icyiciro cya gatatu ifite uburinzi butagira aho bubogamiye.

4.Ubwoko bw'uburinzi:Uburinzi bw'ikwirakwizwa cyangwa uburinzi bwa moteri, bujyanye n'impande zitandukanye.

5.Ibikoresho:Gutembera mu modoka, kurekura undervoltage, ubufasha cyangwa alarm contacts bishobora kongerwamo kugira ngo bigenzurwe kure kandi binasobanure uko ibintu bimeze.

Imanza zo Gusaba Ubusabe bwa RDM5 Series 250A/400A/630A

RDM5-250 (Urufunguzo rwa 250A)

● Ingano y'amashanyarazi: 100–250A

● Ubushobozi bwo gusohora (AC400V): Icu 35–50kA, Ics 25–35kA

● Ikoreshwa risanzwe: Gukwirakwiza amashami mu nganda nto n'iziciriritse, moteri z'ibice bitatu (abafana, ipompo, compressors z'umwuka), sitasiyo nto zo mu bwoko bwa PV box

● Inama zo guhitamo: Gushyira imbere 3P/4P ifite ubushyuhe bwa rukuruzi; verisiyo yo kurinda moteri ku mitwaro ya moteri, hamwe n'uburyo bwo gufasha/gutera alamu.

RDM5-400 (Urufunguzo rwa 400A)

● Ingano y'amashanyarazi: 200–400A

● Ubushobozi bwo gusohora (AC400V): Icu 50–70kA, Ics 35–50kA; Icu 20–25kA kuri AC690V

● Ikoreshwa risanzwe: Ikwirakwizwa ry'ibanze mu matsinda y'amahugurwa, ibigo by'amakuru biciriritse, amadirishya makuru mu nyubako z'ubucuruzi

● Inama zo guhitamo: Isabwa gukoresha 3P/4P hamwe na M-type (medium breaking); H-type high-breaking verisiyo kuri sisitemu nini, hamwe na shunt/undervoltage release kugira ngo irinde kure no kudakoresha volteji.

RDM5-630 (Urufunguzo rwa 630A)

● Ingano y'amashanyarazi: 400–630A

● Ubushobozi bwo gusohora (AC400V): Icu 50–100kA, Ics 50–75kA; Icu 20–35kA kuri AC690V

● Ikoreshwa risanzwe: Ibikoresho binini byinjira, amashanyarazi make asohoka muri sitasiyo, imiyoboro ya bisi z'inganda

● Inama zo guhitamo: Gushyira imbere 3P/4P ifite ubushobozi bwo gukoresha H-type high-breaking capacity; ingenzi mu gukoresha inyongera/alamu ku bijyanye n'insinga z'ingenzi, biboneka mu buryo buhoraho n'ubusanzwe.

Incamake y'Amahitamo Yihuse

● 250A: Imitwaro mito n'iciriritse / ikwirakwizwa ry'amashami → RDM5-250

● 400A: Ikwirakwiza ry'ibanze riciriritse / icyuma gikuru cy'inyubako → RDM5-400

● 630A: Imiyoboro y'amashanyarazi yinjira mu kirere cyangwa iy'ingenzi ifite ingufu nyinshi → RDM5-630

Guhitamo byuzuye kandi byujuje ibisabwa bishobora gukorwa mu ntambwe eshatu:ingano y'amashanyarazi ihuye → genzura ubushobozi bwo gucika → hitamo inkingi n'ibindi bikoresho.
