I-ZGLEDUN LDM9(CM1-Type) i-MCCB ebunjiwe ye-Circuit Breaker

Incazelo emfushane:

I-ZGLEDUN Series LDM9 (i-CM1-Type) i-case breaker breaker (ngemuva kwalokhu ebizwa ngokuthi i-MCCB) ingesinye sezigebengu ezintsha ezithuthukiswe inkampani yethu ngokuklama okuthuthukile kwamazwe ngamazwe kanye nobuchwepheshe bokukhiqiza.I-voltage yayo yokufaka elinganiselwe ingu-800V.Ifanele ukusetshenziselwa ukuguqulwa okungajwayelekile kanye nokuqaliswa okungajwayelekile kwe-electromotor kumasekhethi we-AC 50Hz/60Hz, i-voltage elinganiselwe engekho ngaphezu kuka-690V (400V ochungechungeni lwe-LDM9-63) kanye nokusebenza okulinganiselwe okufika ku-800A.I-circuit breaker inemisebenzi yokulayisha ngokweqile, isifunda esifushane kanye nokuvikelwa kwe-undervoltage, okungavikela isifunda kanye nemishini yamandla ekulimaleni.
Imikhiqizo ingenziwa ngendlela oyifisayo ukuze ihambisane nezidingo zakho.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amazinga Omkhiqizo:

Lo mkhiqizo we-circuit breaker usebenzisa amazinga alandelayo:
◆ Imithetho evamile ye-IEC60947-1 kanye ne-GB/T14048.1
◆ I-IEC60947-2 kanye ne-GB/T14048.2 Isiphakeli sesekethe esiphansi se-voltage
◆ IEC60947-4 kanye ne-GB/T14048.4 Oxhumana nabo neziqalisi zezimoto
◆ IEC60947-5.1 kanye ne-GB/T14048.5 Izinto zikagesi zokulawula i-electromechanical

Izimo Ezivamile Zokusebenza

◆ Izinga lokushisa eliphakathi nendawo: alikho ngaphezu kuka +40℃ (+45℃ emikhiqizweni evamile) futhi lingekho ngaphansi kuka -5℃.Isilinganiso senani elingu-24h aleqi +35℃ (+40℃ emikhiqizweni evamile)
◆ Indawo yokufaka: Ukuphakama akudluli ku-2000m;
◆ Indawo yokufaka: Umswakama ohlobene komoya aweqi ku-50% lapho izinga lokushisa eliphakeme lingu-+40℃.Ingaba nomswakama ophakeme ohlobene nezinga lokushisa eliphansi.Isibonelo, umswakama ohlobene 90% ku-20℃.Izinyathelo ezikhethekile kufanele zithathwe ngokuchayeka okusolisayo ngezikhathi ezithile ngenxa yokushintsha kwezinga lokushisa.
◆ Isigaba sokufakwa:
Isekhethi eyinhloko ye-circuit breaker kanye nokukhululwa kwe-undervoltage: Ibanga lesi-III
Amasekhethi asizayo namasekhethi okulawula: IBanga II
◆ I-circuit breaker ingakwazi ukumelana nomthelela womoya oswakeme, inkungu kasawoti, inkungu kawoyela, isikhunta kanye nemisebe yenuzi.
◆ Ukuthambekela okuphezulu kokufakwa kwe-circuit breaker kungu-±22.5 °
◆ I-circuit breaker ingasebenza ngokwethembeka ngaphansi kwezimo zokuzamazama komhlaba (4g);
◆ I-circuit breaker kufanele ifakwe endaweni lapho ingekho khona ingozi yokuqhuma, ingekho uthuli oluyi-conductive, ukugqwala kwensimbi futhi kungekho monakalo ekushiseni.
◆I-circuit breaker kufanele ifakwe endaweni lapho kungenamvula noma iqhwa.

Ukuhlukaniswa kwe-Circuit Breaker

• Uhlobo A: I-N pole ayifakelwe ukukhishwa okudlulele ( Shunt Trip ).I-N pole ihlala ivuliwe, futhi ayivulwa/icinywe kanye nezinye izigxobo ezintathu.
• Uhlobo B: I-N pole ayifakelwe ukukhishwa kwe-overcurrent ( Shunt Trip ) futhi iyavulwa/iyacinywa kanye nezinye izigxobo ezintathu (i-N pole ivalwa kuqala bese iyavulwa).
• Uhlobo C: I-N pole ifakwe ngokukhulula okudlulele ( Shunt Trip ), futhi iyavulwa/iyacishwa kanye nezinye izigxobo ezintathu (i-N pole ivaliwe kuqala bese ivuliwe).
• Uhlobo D: I-N pole ifakwe nokukhululwa kwe-overcurrent ( Shunt Trip ) .I-N pole ihlale ivuliwe, futhi ayivulwa/ivaliwe kanye nezinye izigxobo ezintathu.

Ikalwe okwamanje (A) :
• LDM9-63: (6A), 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A (6A ngaphandle kokuvikelwa kokugcwala)
• LDM9-125: (10A), 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, 125A
• LDM9-250: 100A, 125A, 140A, 160A, 180A, 200A, 225A, 250A
• LDM9-40 : 225A, 250A, 315A, 350A, 400A
• LDW9-630: 400A, 500A, 630A

Izinhlobo ezine zendlela yokufaka izintambo:
(1)Izintambo zephaneli yangaphambili
(2)Izintambo zephaneli yangemuva
(3)Iphaneli yangaphambili-ifakwe
(4)Iphaneli yangemuva-ifakwe

Izinhlobo Ezimbili Zokukhishwa Kwesikhathi Esidlule (I-Shunt Trip):
(1)Uhlobo lwe-Thermal-electromagnetic (duplex).
(2)Uhlobo lwe-electromagnetic (okusheshayo).

Izinsiza ze-MCCB Molded Circuit Breaker :(1) nezinto ezisetshenziswayo kanye (2) ezingenazo izesekeli.
Kukhona izesekeli zangaphakathi nezesekeli zangaphandle.
Izinsiza zangaphakathi zifaka i-shunt trip, ukukhishwa kwe-undervoltage, ukuthintana nomsizi, ne-alamu.
Izesekeli zangaphandle zihlanganisa indlela yokusebenza yesibambo esizungezisayo, indlela yokusebenza kagesi, isakhiwo sokuxhumanisa, namabhulokhi okugcina izintambo emishini esiza.
