I-6KA MCB Mini Circuit Breaker CAB6-63
Ububanzi Besicelo
I-CAB6-63 yochungechunge lwe-mini circuit breaker (ngemuva kwalokhu ebizwa ngokuthi i-MCB) inemisebenzi yokuvikela ekabili yokulayisha ngokweqile kanye nokujikeleza okufushane.Ifanele isekethe ene-AC 50Hz, i-voltage elinganiselwe engu-230 / 400V futhi ikalwe okwamanje yafika ku-63A, njengomthwalo ogcwele kanye nokuvikelwa kwesekethe emfushane, kanye nokusebenza okungavamile kokuvala kwesekethe.I-crystal inezici zobukhulu obuncane, isisindo esincane, ikhono lokuhlukanisa, i-flame retardant, ukumelana nomthelela, ukufakwa kwesitimela somhlahlandlela, ukuphepha nokuthembeka.Ilungele ukusetshenziswa okungewona ochwepheshe.Isetshenziswa kabanzi emabhizinisini ezimboni nasezimayini, izakhiwo eziphakeme, amabhizinisi kanye nemindeni.
Lolu chungechunge lwama-breaker circuit luhlangabezana nezidingo ze-GB / T1 0963.1.

Izimpawu Zesakhiwo
1. I-MCB ikakhulukazi yakhiwe indlela yokusebenza, abathintwayo abaguqukayo nabamile, iyunithi yohambo, idivayisi yokucisha i-arc nezinye izingxenye.Futhi konke kufakwe kugobolondo le-insulating elenziwe ngepulasitiki eyomile eqinile, ekwazi ukumelana nomthelela.
2. Uma uphusha isibambo sokusebenza endaweni ethi "ON", indlela yokusebenza ivala abathintwayo abahambayo nabamile ukuze bavale isekethe.Uma iphutha lokulayisha ngokweqile lenzeka emgqeni, ukulayisha ngokweqile kubangela ukuthi isici se-bimetal esishisayo sigobe futhi i-vertebral ehambayo i-lever iphinde ibuyisele umshini wokukhiya umshini, futhi othintana naye ohambayo ngokushesha ashiye ukuthintana okumile, ngaleyo ndlela afinyelele ukuvikelwa kokulayisha ngokweqile komugqa;lapho iphutha lesifunda esifushane lenzeka emgqeni, i-short circuit current ibangela i-tripper esheshayo , I-push rod icindezela i-lever ukusetha kabusha indlela yokukhiya ukuze kuzuzwe ukuvikelwa kwesifunda esifushane somjikelezo.
3. Ama-circuit breaker e-2P, 3P kanye ne-4P afakwe idivayisi yokuxhumanisa, futhi isibambo sokusebenza sixhunywe ngentonga yokuxhuma, engeke ibangele ingozi yesigaba esisodwa.
4. Isigxobo ngasinye sinenkomba yokushintsha isimo sokusebenza
Isimo sokusebenza esijwayelekile
1. Izinga lokushisa lomoya osendaweni: -5°C~+40°C, futhi inani elimaphakathi phakathi kwamahora angu-24 alidluli +35°C.
2. Ukuphakama: Ukuphakama kwendawo yokufaka akudluli ku-2000m.
3. Izimo ze-atmospheric: umswakama wesihlobo somoya awudluli u-50% ekushiseni kuka +40 ° C;umswakama ophakeme ohlobene uvunyelwe emazingeni okushisa aphansi, futhi isilinganiso esiphezulu somswakama ohlobene nenyanga emanzi kakhulu ngu-90%, futhi inyanga yenyanga Izinga lokushisa elilinganiselwe alidluli +20°C, futhi kufanele kucatshangelwe ukufiphala okwenzekayo. endaweni yomkhiqizo ngenxa yokushintsha kwezinga lokushisa.
4. Idigri yokungcola: Idigri yokungcola ye-MCB ileveli 2.
5. Isigaba sokufakwa (isigaba se-overvoltage): Isigaba sokufakwa kwe-MCB ngu-II.
6. Ifakwe endaweni engenawo umthelela omkhulu nokudlidliza, ayikho into eqhumayo eyingozi, ayikho indawo yokuqhuma komoya noma uthuli olwanele ukugqwala insimbi futhi yonakalise ukwahlukanisa, akukho mvula nesithwathwa.
7. Izimo zokufaka: I-TH35 ejwayelekile yokuqondisa imigwaqo isetshenziselwa ukufakwa nokufakwa kukhabhinethi yokusabalalisa amandla kanye nebhokisi lokusabalalisa.Lapho uyifaka, kufanele ifakwe iqonde, isibambo sifike endaweni yokuvula amandla.
Ubukhulu bomumo nokufakwa
Ukufakwa, Ukusetshenziswa Nokugcinwa
1. Ukufakwa
◇ Ngesikhathi sokufakwa, hlola ukuthi idatha yobuchwepheshe eyisisekelo ye-nameplate iyahlangabezana yini nezimfuneko zokusetshenziswa.
◇ Hlola i-MCB futhi uyisebenzise izikhathi eziningana.Isenzo sizovumelana nezimo futhi sithembeke.Ukufakwa kungenziwa kuphela ngemva kokuqinisekisa ukuthi akulungile.
◇ I-MCB kufanele ifakwe ngokuhambisana nezidingo ezibaluliwe.Isiphetho esingenayo siwuhlangothi lokuphakelwa kwamandla ngaphezu kwesiphuli, futhi isiphetho esiphumayo siwuhlangothi lomthwalo olungezansi kwe-MCB, indawo engaphezulu yesibambo yindawo evaliwe yoxhumana naye.
◇ Lapho ufaka, qala ngokufaka i-MCB kusitimela esikhwezwayo esijwayelekile esingu-TH35.Bese ufaka izintambo ezingenayo neziphumayo kutheminali, bese usebenzisa izikulufu ukuze ufinyelele i-MCB.Indawo ephambanayo yentambo yokuxhuma ekhethiwe kufanele ihambisane nesilinganiso samanje (bona Ithebula 3).
| Ikalwe okwamanje A | ≤6 | 10 | 15 | 20 | 25 | 32 | 40 | 50 | 63 |
| Indawo yesigaba ye-conductor mm2 | 1 | 1.5 | 2.5 | 2.5 | 4.0 | 6.0 | 10 | 10 | 16 |
2. Ukusetshenziswa nokugcinwa
◇ Izici zokuvikela ze-MCB zizosethwa umkhiqizi, futhi ngeke zilungiswe ngokuthanda kwakhe phakathi nenqubo yokusebenzisa ukuze kugwenywe ukuthikameza ukusebenza.
◇ Ngemuva kokuthi i-MCB iwuhambo ngenxa yokugcwala kakhulu noma ukuvikelwa kwesekethe emfushane, iphutha lizosuswa kuqala bese i-MCB izovalwa.Lapho uvala, isibambo sizodonselwa phansi ukuze kwenziwe umshini wokusebenza kabusha “ubophe”, bese sifuqelwa phezulu ukuze sivale.
◇ Uma isivikelo sokugcwala ngokweqile kwe-MCB siphukile futhi iphutha lisusiwe, kufanele kube yimizuzu eyi-10 ngaphambi kokuvala.
◇ I-MCB izohlolwa njalo phakathi nokusebenza.Ukunikezwa kwamandla kuzonqanyulwa ngesikhathi sokuhlolwa.
◇ I-MCB ngeke ihlaselwe futhi iwe imvula nesithwathwa ngesikhathi sokusetshenziswa, ukugcinwa noma ukuthuthwa.
Uku-oda Iziyalezo
Umsebenzisi kufanele acacise okulandelayo lapho e-oda:
1. Igama nemodeli
2. Ikalwe okwamanje
3. Uhlobo lokukhululwa kwe-overcurrent ngokushesha
4. Inombolo yezigxobo
5. Ubuningi
Isibonelo: oda i-CAB6-63 mini-circuit breaker, ikalwe i-32A yamanje, uhlobo D, 3P (3 pole), ubuningi be-PCS eyi-100.
