250A, 400A thiab 630A yog peb qhov kev ntsuas feem ntau siv rau MCCBs (molded case circuit breakers) hauv kev faib hluav taws xob hauv kev lag luam, kev faib khoom tseem ceeb hauv tsev thiab kev tiv thaiv cov khoom siv. Siv People Electric'sRDM5 series siab tawg-muaj peev xwm MCCBua piv txwv ua tau, tsab xov xwm no piav qhia txog kev xaiv kom meej thiab siv tau los pab cov engineers thiab cov neeg yuav khoom sai sai txheeb xyuas tus qauv zoo.
Cov Ntsiab Cai Xaiv Tseem Ceeb
1.Tam sim no ntsuas (Hauv):Xaiv raws li tag nrho cov load tam sim no muab ntxiv rau 1.25, phim lub zog ntawm cov khoom siv lossis circuits.
2.Lub peev xwm tawg (Icu / Ics):Xaiv raws li lub kaw lus luv luv tam sim no kom ntseeg tau tias muaj kev cuam tshuam txhim khu kev qha hauv qab qhov xwm txheej txhaum.
3.Tus naj npawb ntawm cov ncej:2P rau cov voj voog ib theem, 3P rau cov khoom siv peb theem, 4P rau peb theem plaub-xaim systems nrog kev tiv thaiv nruab nrab.
4.Hom kev tiv thaiv:Kev tiv thaiv kev faib tawm lossis kev tiv thaiv lub cev muaj zog, sib raug rau cov kab sib txawv ntawm kev hla mus los.
5.Cov Khoom Siv:Kev hloov pauv ntawm lub shunt, kev tso tawm qhov hluav taws xob qis, kev sib txuas lus pabcuam lossis lub tswb ceeb toom tuaj yeem ntxiv rau kev tswj chaw taws teeb thiab kev tawm tswv yim xwm txheej.
Cov Ntaub Ntawv Thov RDM5 Series 250A/400A/630A
RDM5-250 (250A Ncej)
● Tam sim no ntsuas: 100–250A
● Muaj peev xwm tawg (AC400V): Icu 35–50kA, Ics 25–35kA
● Cov kev siv ib txwm muaj: Kev faib ceg hauv cov chaw tsim khoom me thiab nruab nrab, cov cav peb theem (kiv cua, twj tso kua mis, cua compressors), cov chaw hloov hluav taws xob me me PV lub thawv hom
● Cov lus qhia xaiv: Ua ntej rau 3P/4P nrog kev tso tawm thermal-magnetic; version tiv thaiv lub cev muaj zog rau cov khoom thauj ntawm lub cev muaj zog, nrog rau kev xaiv cov neeg tiv tauj pabcuam/lub tswb ceeb toom.
RDM5-400 (400A Ncej)
● Tam sim no ntsuas: 200–400A
● Muaj peev xwm tawg (AC400V): Icu 50–70kA, Ics 35–50kA; Icu 20–25kA ntawm AC690V
● Cov ntawv thov ib txwm muaj: Kev faib khoom tseem ceeb hauv cov chaw ua haujlwm, cov chaw khaws ntaub ntawv nruab nrab, cov hloov pauv tseem ceeb hauv cov tsev lag luam
● Cov lus qhia xaiv: Pom zoo kom siv 3P/4P nrog hom M (kev tawg nruab nrab); Hom H uas tawg siab rau cov kab ke loj dua, nrog rau kev tso tawm shunt/kev tso tawm hluav taws xob qis rau kev tiv thaiv chaw taws teeb thiab kev tiv thaiv hluav taws xob qis.
RDM5-630 (630A Ncej)
● Tam sim no ntsuas: 400–630A
● Muaj peev xwm tawg (AC400V): Icu 50–100kA, Ics 50–75kA; Icu 20–35kA ntawm AC690V
● Cov kev siv ib txwm muaj: Cov khoom siv loj loj tuaj, cov khoom siv hluav taws xob tsawg tawm hauv cov chaw hloov pauv, cov khoom siv sib txuas ntawm cov tsheb npav hauv kev lag luam
● Cov lus qhia xaiv: Ua ntej rau 3P/4P nrog H-hom siab-tawg peev xwm; cov neeg tiv tauj pabcuam/ceeb toom tseem ceeb rau cov voj voog tseem ceeb, muaj nyob rau hauv cov qauv ruaj khov thiab rub tawm.
Kev Xaiv Sai Sai
● 250A: Cov khoom me me thiab nruab nrab / kev faib ceg → RDM5-250
● 400A: Qhov chaw faib khoom loj nruab nrab / lub tsev hloov pauv loj → RDM5-400
● 630A: Cov voj voog tseem ceeb / cov voj voog tseem ceeb uas muaj tam sim no siab → RDM5-630
Kev xaiv tiav thiab ua raws li txoj cai tuaj yeem ua tau hauv peb kauj ruam:phim qhov ntsuas tam sim no → xyuas kom meej tias lub peev xwm tawg puas lawm → xaiv cov ncej thiab cov khoom siv.
