I-NHKMC1 Ibhasi Engavimbeli Umlilo ene-4P noma i-5P futhi Ikalwe ngo-250A ~ 6300A Yamanje

Inzuzo

Ukukhethwa kwe-insulation kanye nezinto eziphikisayo ezisebenza kahle kakhulu

• Itheyiphu ye-mica elinyazwe umugqa wethusi womqhubi webhasi ivumelana ne-JB/T5019~20 "imikhiqizo ye-mica insulation kagesi" kanye namazinga e-JB/T6488-1~3 "mica tape".I-mica tape inokuguquguquka okuhle nokumelana nokushisa okuphezulu kanye nezakhiwo ezinhle ze-dielectric kanye nezakhiwo zemishini ngaphansi kwesimo esivamile: amandla okugoba ≥180MPa;amandla e-dielectric ≥35kV/mm;ukumelana nevolumu >1010Ω-m.Lapho izinga lokushisa lifinyelela ku-600℃, i-mica tape isenokumelana okuphezulu kokufakwa kwe-insulation>10MΩmm2.
• Ngokomkhawulo ohlukene wokumelana nomlilo wendlela yebhasi eyi-refractory, izinyathelo ezithathwe ungqimba lokuvikela ukushisa nazo zihlukile.Uma umgwaqo webhasi udinga ukuhamba isikhathi eside ngogesi, isendlalelo sokushisa ukushisa ngokuvamile sivalwa ngokuqondile ngomoya ukuze singaphazamisi ukuchithwa kokushisa ngesikhathi sokusebenza komgwaqo webhasi, nalapho umgwaqo webhasi ungavamisile ukunikwa amandla okusetshenziswa kwamandla ezimo eziphuthumayo. kuphela, umkhawulo wayo wokumelana nokushisa uphakeme futhi isendlalelo sokushisa ukushisa sidinga ukugcwaliswa ngoboya be-silica, izinto zoboya be-silica ezikhethelwe lo mgwaqo webhasi ophikisayo zihambisana ne-GB3003 "i-common aluminosilicate refractory fiber mat" indinganiso, okuqukethwe kwayo kwe-AL2O3 + SiO2 kufinyelela ku-96% , izinga lokushisa lokusetshenziswa okuqhubekayo lingu-1050℃, ^ izinga lokushisa eliphezulu lokusetshenziswa lifinyelela ku-1250℃.
• Lapho umlilo uvela ngaphakathi kwemizuzu engu-3 ~ 5, ukugqoka kuqala ugwebu futhi kwandiswe, kwakha isendlalelo sokushisa ukushisa, futhi ukuqhutshwa kokushisa kwanda ngokushesha, okunciphisa ngokuphumelelayo ukudluliswa kokushisa.Zonke izinkomba zokusebenza ze-refractory coating ezisetshenziswa kulo mzila webhasi oyinqaba zihambisana nezinga likazwelonke le-GB14907-94.
• Ukuze kuhlangatshezwane nezidingo eziphikisayo, ibhulokhi yokuhlukanisa isigaba kanye nebhulokhi yokuhlukanisa ngokuhlanganyela yenziwe ngezinto ze-ceramic eziphikisana nokushisa okuphezulu, ezinokuqukethwe kwe-Al2O3 okungaphezu kuka-95% futhi inezindawo ezilandelayo ze-dielectric kanye nemishini ngaphansi kwezimo ezivamile: amandla e-dielectric. ≥13kV/mm ukumelana nevolumu >20MΩ-cm amandla aguquguqukayo ≥250MPa.I-ceramic iphumelela kakhulu ekuphikeleni kwezinga lokushisa, futhi ukumelana nokushisa okulinganiselwe ku> 10MΩ lapho izinga lokushisa lifinyelela ku-900 ° C.Ngenxa yokuzinza okuhle kwe-ceramic, ayikho inkinga yokuguga yezinto zokufakelwa, ngaleyo ndlela inwebe ngempumelelo impilo yesevisi yomgwaqo webhasi.
• Imikhiqizo ehambisana nemvelo: Uma kuba nomlilo, ayikho igesi enobuthi ephuma emgwaqweni webhasi, futhi akukho ukusha okwesibili okwakhiwayo, okuyisizukulwane esisha semikhiqizo kagesi ehambisana nemvelo.
• Izintambo eziguquguqukayo: I-interface yepulaki yebhasi isethwe ngendlela eguquguqukayo, futhi kulula ukudweba igatsha lamanje.Isixhumanisi ngasinye sepulaki singafakwa emabhokisini ahlukene epulaki, futhi iphinikhodi yebhokisi lepulaki nayo yenziwe ngezinto ze-ceramic ezikwazi ukumelana nokushisa okuphezulu ukuze kuqinisekiswe ukuthi amandla angakhishwa kahle uma kuba nomlilo.
• I-NHCCX series refractory busway iphumelele ngempumelelo isivivinyo sohlobo lwe-National Electric Control Equipment Quality Supervision, Inspection and Testing Center kanye nokuhlolwa kwe-National Chemical Building Material Testing Center, nokusebenza kwayo kukagesi, ukusebenza kwemishini nokusebenza kwe-refractory konke kusekhaya ^ izinga ngokophenyo.
