I-CNH-12/630-20 IGASI EFUNYELWE RING SWITCHGEAR

imininingwane yomkhiqizo

Uhlolojikelele

I-CNH-12/630-20 igesi evumelana nemvelo evalekile i-switchgear yenethiwekhi eyindandatho iwuhlobo olusha lwe-switchgear yensimbi eluhlaza nevumelana nemvelo. Ivalwe ngamagesi angangeni kwemvelo njengomoya owomile noma i-nitrogen, ekhipha igesi ebamba ukushisa engeyona/encane. Izinga lokuphinda lisetshenziswe ngemva kokuba umjikelezo wempilo yomkhiqizo ufinyelele ku-90% % noma ngaphezulu, ngaphandle kwekesi, ezinye izingxenye zokufakwa kwe-insulation empeleni azisebenzisi izinto ezisetshenziswa kanzima ukucekela phansi i-epoxy resin, ezifeza ngempela inhloso yokuba luhlaza kanye nemvelo enobungani. Kokubili ama-breaker circuit kanye nokushintshwa komthwalo kusebenzisa ukucisha kwe-vacuum arc, okuvumelana nezimo zemvelo okuqinile, usayizi omncane, ukonga isikhala, asikho isidingo se-SF, ukutholwa nokuvikelwa kwegesi, ukusebenza okuphephile nokuthembekile, ukunganakekeli, kanye nobuhlakani. Iwukuthuthukiswa kwesikhathi esizayo kweyunithi eyinhloko yeringi. isiqondiso.

I-CNH-12/630-20 igesi evumelana nemvelo evalekile i-switchgear yenethiwekhi yendandatho isetshenziselwa amadivayisi okusabalalisa amandla aphelele ane-voltage engu-12kV, izigaba ezintathu ze-AC 50Hz, ibha yebhasi eyodwa kanye nesistimu yebhasi eyodwa, inethiwekhi yezimboni nesembozo kanye netheminali yenethiwekhi yokusabalalisa. amaphrojekthi. Ngenhloso yokwamukela nokusabalalisa amandla kagesi, asetshenziswa ekusabalaliseni amandla kagesi ezindaweni zokuhlala zasemadolobheni, iziteshi ezincane zesibili, iziteshi zokushintsha, amabhokisi egatsha lezintambo, iziteshi ezincane zohlobo lwamabhokisi, amabhizinisi ezimboni kanye nezimayini, izitolo ezinkulu, izikhumulo zezindiza, imigwaqo engaphansi, umoya. ukukhiqiza ugesi, izibhedlela, nezinkundla zemidlalo. , izitimela, imigudu nezinye izindawo.

Izici Eziyinhloko Zomkhiqizo

◆Imikhiqizo esebenzayo nedidiyelwe eyinkimbinkimbi

Igobolondo le-switchgear eliphefumulayo lenziwe ngepuleti lensimbi engagqwali eliwugqinsi elingu-2.5mm ngokusebenzisa i-laser welding ukuze kuqinisekiswe ukwethembeka kokuvalwa kwebhokisi lomoya, amandla aphezulu emishini kanye nokumelana nokugqwala okuhle. Izinga lokuvikela legobolondo le-inflatable lifinyelela ku-IP67: ibhokisi lomoya lifakwe I-diaphragm evimbela ukuqhuma ingavimbela ngempumelelo umonakalo kubantu kanye nemishini lapho umfutho womoya uphezulu kakhulu; ukufaka uphawu zonke izingxenye ze-conductive ebhokisini lomoya akukwazi nje ukugwema ithonya lezici zemvelo zangaphandle, kodwa futhi kuthuthukise ukuthembeka kokusebenza, okwenza kube mahhala. (noma ukunakekelwa okuncane) umsebenzi, kuyilapho uhlangabezana nezimfuneko zokwenziwa okuncane.

Isifunda esikhulu sisebenzisa inhlanganisela yokushintsha kwezindawo ezintathu (ku + isolation + grounding) kanye nesiphazamisi se-vacuum. Lesi sakhiwo siyindlela yokumisa evuthiwe ngokobuchwepheshe futhi ifanele ukusebenza kwegridi yamandla yamanje kanye nezidingo zokunakekelwa.

◆Inobungani nemvelo futhi ayingcolisi

I-insulating medium ye-CNH-12/630-20 yegesi evumelana nemvelo evala i-switchgear yenethiwekhi yendandatho inguziro-leveli yomoya owomile (ongaphandle) noma u-99.99% we-N2 omsulwa ngokuhambisana ne-GB/T 8979-2008. Ukuvuza kwegesi ngeke kube nomthelela endaweni yangaphandle futhi akudingeki ukuba kwenziwe. Noma yikuphi ukucubungula kokugaya kabusha.

◆ Idizayini yokunweba eguquguqukayo

I-CNH-12/630-20 igesi evumelana nemvelo evalekile i-switchgear yenethiwekhi eyindandatho iyimojuli ekwakhiweni, futhi amamojula ahlukahlukene angaxhunywa ngezixhumi ezizinikezele zebha yebhasi. Zuza inhlanganisela yamayunithi ahlukahlukene ukuze uhlangabezane nezikimu zedizayini zokusabalalisa amandla eziyinkimbinkimbi futhi ezihlukahlukene ezindaweni ezihlukahlukene e-China ngezinga elikhulu kakhulu.

◆Ukuhlangana kwemishini okuphelele

Iphaneli yokusebenza ye-CNH-12/630-20 yegesi enobungani nemvelo evaliwe ye-switchgear yenethiwekhi inobufakazi obuyisihlanu obuphelele bokuhlanganisa umsebenzi. Yonke imisebenzi ehlanganisiwe ilungiselelwe ngaphakathi. Sicela usebenze ngokulandela imiyalelo yokusebenza. Kulula kakhulu ukuyisebenzisa.
