Uhlolojikelele

Uhlobo lwe-RVB yohlobo lwe-vacuum circuit breaker yangaphandle emboza i-12kV kufika ku-36kV ububanzi besiteshi se-transformer kanye nesiteshi sokushintsha sisebenzisa.
Isilinganiso samanje: 630A,....2500A, isilinganiso samanje sokuphulwa kwesekethe emfushane: 25kA,...40kA.
Idizayini yayo ephelele esikhundleni sohlobo lwendabuko olufana no-OHB, VBF, 3AF, ZW7, ZW30, ZW39, ZW37... njll.
Ukukhanya okwengeziwe, okuhlangene, okuthembekile, kanye nemvelo-yobunganiKwathuthukiswa uchungechunge lwe-RVB-40.5 lwe-vacuum circuit breaker kusetshenziswa ubuchwepheshe besimanje bokucubungula kanye namasu okuklama asizwa ngekhompiyutha,
kuhlanganiswe nesizukulwane sakamuva semizimba yasentwasahlobo kanye nezinzuzo zesikhungo esihlala njalo.Ukuphishekela ukwethembeka okuphezulu,
kulula ukugcina imiqondo yokuklama ukudala isizukulwane somkhiqizo ophakeme, isistimu yamandla kagesi ethembeke kakhulu inketho engcono kakhulu.
I-RVB-40.5uchungechunge lwamaswishi esofthiwe yokusetshenziswa eyinhloko nomsebenzi oqinile oklanywe ngokuhle, okuphephile nokuthembekile sekukonke.
Amaswishi e-RVB-40.5Series anezinhlobonhlobo zezitayela ongakhetha kuzo:
I-RVB-40.5Izigebengu ezijwayelekile zangaphandle ze-vacuum, i-spring actuator iza ejwayelekile nempilo yobumishini izikhathi ezingu-20,000.
Wonke amaswishi ochungechunge ahlangabezana nemibandela elandelayo:
ANSI/IEEE C37.60/IEC 62271-100( GB1984-2003 China standard)
I-GBT11022-1999 China Standard
I-IEC 60255-11
I-IEC 60255-21-1 Ikilasi I
I-IEC 60255-21-2 Ikilasi I
I-IEC 60255-21-3 Isigaba I
I-IEC 60255-22-1 Isigaba III
I-IEC 60255-22-2 Isigaba IV
I-IEC 60255-22-3 Isigaba III
I-IEC 60255-22-4 Isigaba IV
I-RVB-40.5 Uhlobo lwasentwasahlobo izici eziyinhloko ze-VCB
Idivayisi ethembekile yokuvula ngesandla
Ukuvala okunokwethenjelwa nokonga abasebenzi
Inkomba yokuvala encane ebonakalayo
Isixhumi sepulaki yekilasi lokuvikela le-IP64

Incazelo:

Inikeza idizayini eyingqayizivele yokushintsha ngesandla kubuchwepheshe ukuze kuhlangatshezwane nesimo sezici ezivamile nezingajwayelekile zokuvala.Ijubane layo lokuhlangabezana ne-IEC62271-100 kanye nezidingo ezijwayelekile ze-GB1984-2003 ezifanayo.
Ukuvela kobuchwepheshe bokwenza izikhungo ezihlala unomphela nama-ejensi ekushiyekeni kwabo kwentwasahlobo ngokulandelana, kuyisizukulwane esisha sokusebenza okuphezulu kokushintsha amandla okuhlukanisa izici.
Itheminali yebha yebhasi eyinhloko (ukugqagqana okuqondile nesiphazamisi ukunciphisa ukulahleka kwamandla okungadingekile)
Isiphazamisi se-vacuum (inqubo ye-APG esebenzisa ubuchwepheshe bokuvala uphawu obuqinile obuqinile, kanye nobuchwepheshe obuhlanganisiwe bokubumba irabha ye-silicone ukuze kuthuthukiswe ukusebenza kwesimo sezulu esishintshayo)
Ipayipi elikhiphayo elinwebekayo (kanye nedizayini eyimojuli, ezosiza i-insulation margin yesiqiniseko kanye nezidingo zokushintshwa komkhiqizo)
I-RVB yochungechunge lwe-vacuum switch yenqatshwa kwemiqondo yedizayini yokushintsha yendabuko, izomunca eminye yemibono yedizayini ethuthukisiwe, yenze kube lula ukushintshwa kwemodi yokudlulisa yonke,
ukunciphisa kakhulu ukulahleka kwamandla okudlulisela kwalolu shintsho kwenza ukushintsha ukusebenza okungcono kakhulu kanye nempilo ende.
Kwenza amaswishi omzimba wonke anikeze isikhathi sokuphila esiphezulu, izakhiwo ezinzile.
I-RVB-40.5N ihlinzeka ngokuphindwe izikhathi ezingu-25,000 ukusebenza kwemishini yokuphila, izikhungo izikhathi ezingu-20,000 inani lokusebenza ngaphandle kokulungisa.
I-RVB-40.5Mto ihlinzeka izikhathi ezifika kweziyi-100,000 ukusebenza ngomshini wokuphila
