Uchungechunge lwe-RDV6-12 I-High voltage AC Vacuum Circuit Breaker iyi-3-phase A C12kV indoor switch device ivame ukufakwa ochungechungeni lwekhabhinethi yohlobo oluphakathi lwe-KY28, isiteshi esincane sebhokisi kanye nekhabhinethi yohlobo lwe-Armored, njengesivikelo semboni, imishini kagesi yebhizinisi lezimayini kanye nesekethe yokwenza nokuphula kusuka ku-load current, i-overload current kanye ne-short-circuit protect current. Futhi Ngenxa yokusebenzisa i-Vacuum breaker, lo mkhiqizo ulungele ngokukhethekile indawo yokusebenza njalo ngaphansi kohlelo lokusebenza olulinganiselwe, noma ukuvula nokuphula i-short-circuit izikhathi eziningi.
1. Inqubo yokusebenza okuqinisekisiwe
2.Ivolumu encane, umthamo omkhulu
3. Umthamo wokuxhuma izintambo onamandla kakhulu
4. Ukufakwa kahle kwe-insulation phakathi kwezigaba
5. Ukuqhuba okunamandla kakhulu
6. Ukwenyuka kwezinga lokushisa eliphansi kanye nokusetshenziswa kwamandla
Incazelo Yemodeli
Indawo ezungezile
a) Izinga lokushisa: Okuphezulu +40C, Okuncane -10C (30C, indawo yokugcina kanye nokuthuthwa)
b) Ukuphakama: Ubuningi obungu-2000m. Isidingo esikhethekile sizoxhumana nathi.
c) Umswakama ohlobene: isilinganiso sosuku akufanele sidlule ku-95%, isilinganiso senyanga akufanele sidlule ku-90%. Futhi isilinganiso sosuku somfutho womusi ogcwele akufanele sidlule ku-2.2kPa, isilinganiso senyanga akufanele sidlule ku-1.8kPa. Futhi ngosuku lomswakama ophezulu, kubanda,
ukufinyela kuyamukeleka.
d) Izinga lokuzamazama komhlaba: kungabi ngaphezu kwezinga lesi-8
e) Faka indawo: ngaphandle komlilo, ukuqhuma, uthuli, ukugqwala kwamakhemikhali, kusobala
Umsebenzi oyisisekelo kanye nesici
1. Igumbi lokucisha i-arc ye-Vacuum lisebenzisa izinto zokuxhumana ze-Cu Cr, kanye nesakhiwo sokuxhumana esimise okwe-Cup sensimu yamagnetic ende enesilinganiso esincane sokuguguleka, Amandla e-dielectric azinzile ukululama okusheshayo ngemva kokucima i-arc, izinga eliphansi lokuvala, amandla okwakha nokuphuka aqinile, impilo ende kagesi.
2. Phakathi kwesigxobo sokufaka umoya kanye negobolondo le-ceramic legumbi lokucisha i-vacuum arc. Ukusebenzisa i-buffer yerabha ye-silicon ewuketshezi, kwandisa ukusebenza kokumelana nomthelela, I-ambrellaskirt enebanga elikhulu lokukhuphuka ebusweni bensika yesigxobo, ukuthuthukisa i-voltage yokumelana ne-powerfrequency kanye ne-lightning impulse voltage yokumelana ne-voltage, ingahlangabezana nezidingo zobuchwepheshe eziyinhloko zendawo ephakeme.
3. Indlela yokusebenza yindlela yokugcina amandla yasentwasahlobo yokuhlelwa kwendiza, inemisebenzi yokugcina ngesandla kanye neyokugcina imoto, ukuthuthukisa ukuzinza kokusebenza.
4. Le ndlela yokusebenza ye-circuit breaker, nayo eyamukelwe yi-Permanent magnetic actuatormechanism, le ndlela inciphisa izingxenye ezingama-60% uma kuqhathaniswa nentwasahlobo evamile, inciphisa izinga lokuphutha ngenxa yezingxenye.
