China Factory CJMM3-250L/3300 Electrical MCCB Molded Case Circuit Breaker

Tsananguro pfupi:

CJMM3 Moulded case circuit breaker (inozivikanwawo secircuit breaker) ine hunhu hwehukuru hudiki, kugona kukuru kwekupwanya magetsi, kugona kupfupika, uye kudzivirira kudedera. Yakakodzera network dzekugovera magetsi dzine AC 50Hz, voltage yekushanda yakayerwa 400V, uye current yekushanda yakayerwa kusvika ku250A zvichidzika. Inoshandiswa kuparadzira simba remagetsi uye kudzivirira mitsetse nemidziyo yemagetsi kubva pakuwanda, short circuit nezvimwe zvikanganiso. Inogona zvakare kushandiswa pakuchinjana kwemasekete kakawanda uye kutanga kwemamota nguva nenguva. Circuit breaker inogona kuiswa yakatwasuka (ndiko kuti, kuiswa yakatwasuka) kana yakatwasuka (ndiko kuti, yakaiswa yakatwasuka).

Chigadzirwa ichi chinoenderana neIEC60947-2 uye GB/T14048.2 “Switchgear ine simba shoma uye michina yekudzora Chikamu 2: Circuit breakers”.

Mamiriro Ekushanda Uye Kuisa

Kureba kwenzvimbo yekuisa hakupfuuri 2000m.
Tembiricha yemhepo iri munzvimbo;
Muganho wepamusoro wekupisa kwemhepo yekunze haupfuure +40°C;
Avhareji yekupisa kwemhepo inotonhorera kwemaawa makumi maviri nemana haipfuure +35°C;
Muganho wakaderera wekupisa kwemhepo uri pakati nepakati hausi pasi pe -5°C;
Mamiriro ekunze:
Hunyoro hwemhepo hahupfuure 50% kana tembiricha yepamusoro iri +40°C. Hunogona kuva nehunyoro hwakanyanya patembiricha yakaderera. Kana tembiricha yepasi pemwedzi wega wega yemwedzi unonaya zvakanyanya isingapfuure +25°C, hunyoro hwemhepo hahupfuure +25°C. Hunyoro hwepamusoro hwe90%, tichifunga nezvekuoma kwemvura pamusoro pechigadzirwa nekuda kwekuchinja kwetembiricha.

Kusiyana pakati peM1 series neM3 series MCCB

Moulded case circuit breakers (MCCB) zvinhu zvakakosha mumagetsi, zvichidzivirira overload uye short-circuit. Kana zvasvika kuMCCBs, M1 series neM3 series isarudzo mbiri dzakakurumbira, imwe neimwe ine maficha ayo uye kugona kwayo. Kunzwisisa mutsauko uripo pakati pemaseti aya kunogona kubatsira vashandisi kuita sarudzo dzakagadzirwa neruzivo pavanenge vachisarudza MCCB inonyatsokodzera zvavanoda.

M1 Series MCCB yakagadzirirwa kushandiswa uko kushanda kwakajairika kwakakwana. Inopa dziviriro yakavimbika kumaseketi nemidziyo, ine zvinhu zvakaita sekugadzirisa mafambiro ekupisa uye emagineti. Yakakodzera kushandiswa kwakasiyana-siyana kwemaindasitiri nemabhizimisi, M1 Series inopa dziviriro inodhura zvishoma pasina kukanganisa mhando nekuchengetedzeka.

Ma M3 series molded case circuit breakers, kune rumwe rutivi, akagadzirirwa kusangana nezvinodiwa zvemagetsi akaomarara uye akakosha. Anopa maficha ekudzivirira epamusoro anosanganisira adjustable thermal release uye magnetic release, pamwe nesarudzo dzekuwedzera dzekudzivirira kukanganisa kwepasi uye kugona kutaurirana. M3 Series yakakodzera mashandisirwo anoda kushanda kwakawedzerwa uye kuchinjika, senge zvivakwa zvikuru zvemaindasitiri uye kuiswa kwezvivakwa zvakakosha.

Chimwe chezvinhu zvikuru zvakasiyana pakati peM1 neM3 series MCCBs ibasa radzo uye mashandiro adzo. M1 Series inopa dziviriro yakavimbika kune mashandisirwo akajairwa, nepo M3 Series ichipa maficha epamusoro uye sarudzo dzenzvimbo dzinoda kushanda zvakanyanya. Pamusoro pezvo, M3 series inogona kunge iine kugona kukuru kwekupwanya kupfuura M1 series uye inogona kupwanya ma fault currents akakwira.

Muchidimbu, kusarudzwa kweM1 neM3 series molded case circuit breakers zvinoenderana nezvinodiwa chaizvo zvesystem yemagetsi inobatanidzwa. M1 Series inopa dziviriro inodhura zvishoma kune mashandisirwo akajairwa, nepo M3 Series ichipa maficha epamusoro uye kugona kwekuisa kwakaoma uye kwakakosha. Kunzwisisa mutsauko uripo pakati peseries idzi kwakakosha pakusarudza molded case circuit breaker yakakodzera kuve nechokwadi chekuchengetedzwa uye kuvimbika kwesystem yako yemagetsi.
