I-MLM1 Mulang Electric yezigaba ezintathu ezinezintambo ezine switch yomoya ye-MLM1 MCCB main gate switch ye-MCCB

ukubuka konke
I-MLM1 series case plastic circuit breaker (ngemuva kwalokhu ebizwa ngokuthi yi-circuit breaker), ifanele i-AC 50Hz noma i-60Hzits elinganiselwe i-voltage yokufaka ingu-800V(MLM1-63 ingu-500V), i-voltage yokusebenza elinganiselwe ingu-690V(MLM1-63 ingu-400V nangaphansi), isetshenziselwa ukushintsha okungajwayelekile kanye nokuqaliswa okungajwayelekile kwamamotho kumasekhethi anesilinganiso sokusebenza samanje esifika ku-1250A (Inm<630Aand ngezansi).Isiphuli sesekhethi sinomthwalo ogcwele, isekethe emfushane kanye nemisebenzi yokuvikela i-undervoltage engavikela isekethe nezisetshenziswa zokuphakela amandla ekulimaleni.
Ama-Circuit breaker ahlukaniswe abe izinhlobo ezintathu: uhlobo L(uhlobo olujwayelekile), uMtype(uhlobo olunqamulayo oluphezulu), kanye no-H (uhlobo oluphukayo oluphezulu) ngokuya ngomthamo wabo olinganiselwe wokuphulwa kwesekethe.I-circuit breaker inezici zosayizi omncane, i-high breaking capacityshort flashover, anti-vibration, njll.Kungumkhiqizo olungele umhlaba kanye nemikhumbi.
I-circuit breaker ingafakwa mpo (okungukufakwa okuqondile) noma ngokuvundlile (okungukuthi, ukufakwa okuvundlile).
I-circuit breaker ihlangabezana namazinga: EC60947-2 kanye ne-GB14048.2

Qaphela: Kunezinhlobo ezine zezigxobo ezingathathi hlangothi (i-N pole yemikhiqizo yezigxobo ezine
Uhlobo A lwe-N-pole alufakelwe isici sokukhubeka esidlule,
Futhi i-N pole ihlale ixhunyiwe, futhi ayivali futhi ivule nezinye izigxobo ezintathu;
Uhlobo B lwe-N-pole alufakwanga ngento yokugibeza yamanje,
Futhi iN pole ihlanganiswa nezinye izigxobo ezintathu;(N pole ihlanganiswa kuqala bese iyahlukaniswa);
I-C-type N pole ifakwe isici sokukhubeka manje,
Futhi isigxobo esingu-N sihlanganiswa nezinye izigxobo ezintathu;(i-N pole ihlanganiswa kuqala bese ihlukaniswa):
Isigxobo sohlobo lwe-D sifakwe isici sokukhululwa esidlule, futhi iNpole ihlale ixhumekile, futhi ayivali futhi ivuleke nezinye izigxobo ezintathu;

izimo zokusebenza ezijwayelekile
Izinga lokushisa elizungezile eliphakathi nendawo: alikho ngaphezulu kuka +40°C(+45*C emikhiqizweni evame ukusetshenziswa)futhi hhayi ngaphansi kuka -5°C, futhi inani elimaphakathi lamahora angu-24 alidluli+35C(+40°C emikhiqizweni evame ukusetshenziswa) ;
Indawo yokufaka: ukuphakama akudluli ku-2000m;
Indawo yokufakela: Umswakama ohlobene womoya aweqi ku-50% uma izinga lokushisa eliphakeme kakhulu lingu +40°C. ukufingqa ngezikhathi ezithile ngenxa yoshintsho lokushisa kufanele kuthathwe izinyathelo ezikhethekile;
Izinga lokungcola: Izinga lesi-3;
Isigaba sokufakwa: Isigaba sokufakwa sesekhethi eyinhloko ye-circuit breaker kanye nokukhululwa kwe-undervoitage ll, futhi isigaba sokufakwa sawo wonke amanye amasekhethi asizayo nokulawula ithi I;
I-circuit breaker ingakwazi ukumelana nomthelela we-airsait sprayoil mistmold emswakama kanye nemisebe yenuzi;
Ukuthambekela okuphezulu kokufakwa kwe-circuit breaker yi-±22.5 °;
I-circuit breaker ingasebenza ngokuthembekile ngaphansi kwesimo sokuzamazama komhlaba(4g);
I-circuit breaker kufanele ifakwe endaweni lapho kungekho khona ingozi yokuqhuma, kungekho uthuli oluqhutshwayo, akukho ukugqwala kwensimbi futhi kungekho monakalo ekufakweni;
I-circuit breaker kufanele ifakwe endaweni engenamvula neqhwa.

Ukuhlukaniswa kwama-circuit breaker
Uhlobo A: Akukho ukukhishwa kwe-overcurrent okufakwa esigxotsheni se-N, futhi i-Npole ihlala ixhunyiwe, futhi ayivali futhi ivuleke nezinye izigxobo ezintathu.
Uhlobo B: Akukho ukukhishwa kwe-overcurrent okufakwa esigxotsheni esingu-N, futhi isigxobo esingu-N siyavalwa futhi sivulwe kanye nezinye izigxobo ezintathu (i-N pole ivalwa kuqala bese ivulwa).
Uhlobo C:Isigxobo esingu-N sifakwe ukukhululwa kwe-overcurrent, bese i-N pole ivaliwe futhi ivulwe kanye nezinye izigxobo ezintathu (isigxobo esingu-N sivalwa kuqala bese siyavulwa). Uhlobo D: Isigxobo sika-N sifakwe ukukhululwa okudlulele ,kanti iN pole ihlale ixhumekile,ayivali futhi ivuleke nezinye izigxobo ezintathu.

Ngokusho kwamanje okulinganiselwe (A)
I-MLM1-63is(6),10,16,20,25,32,40,50,63A amazinga ayisishiyagalolunye(6Ukucaciswa ngaphandle kokuvikela ukulayisha ngokweqile);MLM1-125 s(10),16,20,25,32,40,50, 63,80,100,125A level elever;
I-MLM1-250is100,125,140,160,180,200,225,250A amazinga ayisishiyagalombili;MLM1-400 ingamazinga ayi-225,250,315,350,400A amahlanu;
I-MLM1-630 inamazinga amathathu angu-400,500, kanye no-630A; i-MLM1-800 inamazinga amathathu angu-630,700, kanye no-800A.[With()akunconyiwe ukucaciswa]

Ngokwemodi yokufaka izintambo, ihlukaniswe yaba izinhlobo ezine: izintambo zephaneli yangaphambili, izintambo zephaneli yangemuva, izintambo ze-plug-in front-panel, kanye ne-plug-in back-panel wiring.
Ngokusho kohlobo lokukhishwa kwe-overcurrent, ingahlukaniswa ngohlobo lwe-thermal-electromagnetic(complex) kanye nohlobo lwe-electromagnetic (okusheshayo).
Ngokusho kokuthi i-circuit breaker ine-accessories.kunezinhlobo ezimbili: ezinezesekeli futhi ezingenazo izesekeli:
Okunamathiselwe kuhlukaniswe kwaba okunamathiselwe kwangaphakathi nokunamathiselwe kwangaphandle;
Izinsiza zangaphakathi zifaka ukukhishwa kwe-shunt, ukukhishwa kwe-undervoltage, ukuthintana nomsizi, nokuxhumana kwe-alamu.Izinsiza zangaphandle zifaka indlela yokusebenza yesibambo esijikelezayo, indlela yokusebenza kagesi,isakhiwo esikhiyayo kanye nebhulokhi yetheminali yamadivayisi asizayo, njll.

Qaphela:
1.200: ikhombisa i-circuit breaker ene-electromagnetic release kuphela; 300:Ibonisa i-circuit breaker enokukhishwa kwe-thermal-electromagnetic;
2.Ku-MLM1-125,250 ama-circuit breaker anezigxobo ezine, awekho angu-240,340,260,360,268,368 uma isigxobo sika-N siwuhlobo A bese uthayipha D
3.Okwe-MLM1-400.MLM1-630 kanye ne-MLM1-800, othintana nabo abayisiza ku-248.348.278.kanye nezicaciso ze-378 yipheya yoxhumene nabo (okungukuthi. oyedwa ovamise ukuvuleka futhi avamise ukuvala), kanye nomsizi othintana naye ku-268,368 imininingwane ikhanda lingamapheya amathathu othintana nawo (lokho okuthathu kuvame ukuvuleka futhi amathathu kuvame ukuvaleka).
Ukucaciswa okumakwe ngakho kunganikeza amasethi amabili othintana nabo abasiza (ngaphandle kwe-MLM1-63), kodwa kufanele kucaciswe lapho ku-oda.
