I-miniature circuit breaker

I-Miniature Circuit Breaker eyaziwa nangokuthi i-Micro Circuit Breaker, ifanele i-AC 50/60Hz elinganiselwe i-voltage engu-230/400V, ikalwe ngokwamanje ukuze ibe ngu-63A ukulayisha ngokweqile kwesekethe kanye nokuvikelwa kwesekethe emfushane.Ingasetshenziswa futhi njengokuguqulwa kokusebenza okungajwayelekile komugqa ngaphansi kwezimo ezijwayelekile.Ama-breaker circuit amancane asetshenziswa ikakhulukazi ezimbonini, ezentengiselwano, eziphakeme kanye nezindawo zokuhlala nezinye izindawo.Umkhiqizo kufanele uhambisane namazinga e-IEC60898.

Izimo zokusebenza:

1) Inani eliphezulu lomkhawulo wokushisa komoya okuzungezile akufanele lidlule +40 ° C, inani eliphansi lomkhawulo akufanele libe ngaphansi kuka -5 ° C, futhi izinga lokushisa eliphakathi kuka-24h ngeke lidlule +35 ° C;

Qaphela 1: Umkhawulo ophansi yizimo zokusebenza -10℃ noma -25℃, umsebenzisi kufanele amemezele kumkhiqizi lapho e-oda;

Qaphela 2: Uma umkhawulo ophezulu udlula +40 ° C noma umkhawulo ophansi ungaphansi kuka -25 ° C, umsebenzisi kufanele axoxisane nomkhiqizi.

2) Ukuphakama kwendawo yokufaka akudluli ku-2000m;

Umswakama ohlobene nomkhathi aweqi ku-50% lapho izinga lokushisa lomoya elizungezile liku-+40 ° C, futhi inani eliphezulu lomkhawulo lokushisa lomoya elizungezile lingavunyelwa ukuba libe nomswakama ophakeme oyisihlobo emazingeni okushisa aphansi angeqi +40 ° C, inani eliphansi lomkhawulo alikho ngaphansi kuka -5 ° C, futhi izinga lokushisa eliphakathi kuka-24h alidluli +35 ° C;Isibonelo, kuze kufike ku-90% ku-+20 ° C, izinyathelo ezifanele kufanele zithathwe ukuze kuhlanganiswe ngezikhathi ezithile okubangelwa ukushintsha kwezinga lokushisa;

4), izinga lokungcola :2;

5), isigaba sokufakwa: I-Class II ne-Class III;

6) Indawo kazibuthe yangaphandle yendawo yokufaka akufanele yeqe izikhathi ezi-5 kunenkundla ye-geomagnetic kunoma iyiphi indlela;

7), ukufakwa okujwayelekile okuqondile, noma yikuphi ukubekezelela isiqondiso 2 °;

8) Akufanele kube khona umthelela obalulekile nokudlidliza ekufakweni.

I-miniature circuit breaker inezici zesakhiwo esithuthukisiwe, ukusebenza okuthembekile, ikhono eliqinile lokuphuka, ukubukeka okuhle nokuncane, njll. Isetshenziswa kakhulu endaweni lapho i-AC ingu-50HZ noma i-60HZ, i-voltage elinganiselwe ingaphansi kuka-400V kanye nokusebenza okulinganiselwe. yamanje ingaphansi kuka-63A.Isetshenziselwa ukulayisha ngokweqile kanye nokuvikela isifunda esifushane sokukhanyisa, imigqa yokusabalalisa kanye nemishini yezakhiwo zamahhovisi, izakhiwo zokuhlala kanye nezakhiwo ezifanayo, futhi ingasetshenziselwa ukusebenza okungavamile kokuvala nokuguqulwa kwemigqa.Isetshenziswa kakhulu ezimbonini, ezentengiselwano, eziphakeme kanye nezindawo zokuhlala nezinye izindawo.

Lapho ugoqa i-mini-circuit breaker evame ukusetshenziswa kakhulu ukuze kuphuke isekethe, ukuthintana okunyakazayo kwe-mini-circuit breaker kuhlukaniswa nokuxhumana okugxilile ngendlela yomshini.Uma iswishi ivaliwe, ukunyakaza okuphambene kuyasetshenziswa ukuvala othintana naye onyakazayo nothintwayo ogxilile.Uma isifunda somthwalo sivulwa futhi sivalwa, i-arc izokwenzeka phakathi kothintana naye ogxilile nothintana naye onyakazayo.I-arc ekhiqizwa inqubo yokuphuka ibucayi kakhulu kunenqubo yokuvala.Lapho i-breaking current inkulu kakhulu, ikakhulukazi lapho isifunda esifushane siphukile, i-arc inkulu kakhulu, futhi ngokuvamile kunzima kakhulu ukunqamula isifunda.
