I-ZN73-12 series indoor three-phase AC high-voltage vacuum circuit breaker eyenziwe yi-People Electric iyidivayisi yokuvikela ukushintshashintsha okuyisisekelo elungiselelwe izinhlelo zamandla ze-AC zesigaba sesithathu ze-12kV, 50Hz. Yenzelwe amabhizinisi ezimboni kanye nezimayini, izitshalo zamandla, iziteshi ezincane kanye nezinye izimo, isebenza njengedivayisi ebalulekile ebaluleke kakhulu ezinhlelweni zokusabalalisa amandla ezimboni, ngezinzuzo eziyinhloko kanye nokuzivumelanisa nezimo kubonakala ezicini ezine:
1.Ukulungiswa Kwesimo Esinembile Nokubekwa Kwendawo Eyinhloko: Ivumela ukushintsha imithwalo eyahlukahlukene kanye nokuvikelwa nokulawulwa kwezikhungo zikagesi, ikakhulukazi ezifanele izimo zamandla ezimboni ezidingaimisebenzi ejwayelekile, enikeza izixazululo zokuvikela amandla eziqondiwe kanye nokulawula izimo zokusatshalaliswa kwamandla aphezulu ezikalini ezahlukene.
2.Ukusebenza Okuhle Kakhulu Kokucisha Umlilo Nokuklama Isakhiwo: Isebenzisa i-vacuum njengento yokuxhumana eqeda i-arc kanye ne-insulating medium kanye ne-copper-chromium, inokuguga okuphansi kukagesi, ukumelana namandla aphezulu kagesi kanye nokubuyiselwa okusheshayo kwamandla okuvikela ngemuva kwe-arc ukuze kunqunywe ama-fault currents ngokushesha nangokuzinzile. Isebenzisa isakhiwo esihlanganisiwe esinendlela yokusebenza kanye negumbi lokucisha i-arc elihlelwe ngaphambili nangemuva, kanye nesekethe eyinhloko yomoya enezigaba ezintathu. Ikamelo lokucisha i-arc lifakwe ku-cylinder cast ene-epoxy resin ngobuchwepheshe be-APG, okunikeza ukumelana okunamandla kokudonsa kanye nokuqongelela uthuli oluphansi. Okwamanje, inciphisa izixhumanisi zokudlulisela eziphakathi ukuze kuncishiswe ukusetshenziswa kwamandla nomsindo ngokusebenza okuthembekile.
3.Ukucushwa Kwesakhiwo Okuguquguqukayo Nokuvikelwa Okuphelele: Itholakala ngouhlobo oluhleliwefuthiuhlobo lokudonsa, ingafakwa kumakhabhinethi okushintsha aqinile nalawa angakhishwa ngokulandelana ukuze ihlangabezane nezidingo ezahlukene zokufakwa nokusebenza kanye nokugcinwa. Ifakwe izingxenye zokuvikela zikagesi eziphelele okuhlanganisa i-anti-trip relay, i-over-current electromagnet tripping kanye ne-micro-switch yokugcina amandla, ithuthukisa kakhulu ukuphepha kokusebenza. Isebenza kahle kusukela ku--10℃ kuya ku-+40℃, imelana nokuzamazama komhlaba kufika ku-8 magnitude, futhi isebenza ngokuthembeka ezindaweni ezingenamagesi aqothulayo/avuthayo noma ukudlidliza okukhulu. Izinsizakalo ezenziwe ngokwezifiso zinikezwa ngezimo zokusebenza ezikhethekile.
4.Ukukhethwa Kwemodeli Ehlukahlukene kanye Nezindleko Eziphansi Zokusebenza Nokulungisa: Umthamo wamanje olinganiselwe usukela ku-630A kuya ku-3150A, kanti umkhawulo wamanje wokuphuka kwe-short-circuit uhlanganisa u-20kA kuya ku-40kA, okuvumela ukukhetha okuguquguqukayo ngokusekelwe kumthamo wamanje womthwalo okhona endaweni. Njengoba isikhathi eside sesevisi yemishini, ukulungiswa okulula, ukungcola okungekho futhi kungekho bungozi bokuqhuma, kunciphisa ngempumelelo izindleko zokusebenza nokugcinwa kwabasebenzisi bezimboni.
Okuvelele Komkhiqizo Okuyinhloko
1.Isici Somkhiqizo: I-vacuum circuit breaker ye-AC enezigaba ezintathu yangaphakathi evumelaniswe nezinhlelo zamandla ze-12kV/50Hz, ihambisana nezindinganiso zikazwelonke. I-vacuum arc-extinguishing medium iqinisekisa ukusebenza kahle kokucima i-arc kanye nokusebenza kokuvikela.
2.Izinzuzo Eziyinhloko: Ukuxhumana kwe-Copper-chromium okugugile kancane futhi okuphila isikhathi eside; isakhiwo esihlanganisiwe esinokusetshenziswa kwamandla okuphansi, ukumelana nokukhukhuleka kanye nokumelana nokungcola; impilo yesevisi yemishini yezikhathi eziyi-10,000, ukuvulwa/ukuvala okusheshayoimpendulo kanye nomthamo oqinile wokuphula amaphutha; izingxenye zokuvikela eziphelele ukuze kusebenze kahle kakhulu.
3.Izimo Zohlelo Lokusebenza: Ukuvikelwa nokulawulwa kwezikhungo zikagesi emabhizinisini ezimboni kanye nawezimayini, ezitshalweni zikagesi, eziteshini ezincane,ifaneleka kakhulu ekushintsheni umthwalo ngokusebenza njalo.
4.Isakhiwo Nokwenza Ngokwezifiso: Izakhiwo ezilungisiwe nezidonswayo ezilungisekayo kumakhabhinethi ahlukahlukene okushintsha; ukukhiqizwa okwenziwe ngokwezifiso kuyatholakala ezimweni zokusebenza ezikhethekile ezivumelana nezimo zemvelo eziqinile.
