I-NHKMC1 iBusway enganyangekiyo kuMlilo ene-4P okanye i-5P kwaye iNqatywe ngoku 250A~6300A

Inzuzo

Ukukhethwa kwe-insulation kunye ne-refractory materials kunye nokusebenza okugqwesileyo

• I-mica tape inxeba ngomqolo wobhedu we-busway conductor ihambelana ne-JB / T5019 ~ 20 "imveliso ye-electrical insulation mica" kunye nemigangatho ye-JB / T6488-1 ~ 3 "mica tape".I-mica tape ine-flexibility efanelekileyo kunye nokumelana nokushisa okuphezulu kunye neempawu ezintle ze-dielectric kunye nezixhobo zomatshini phantsi kweemeko eziqhelekileyo: amandla okugoba ≥180MPa;amandla edielectric ≥35kV/mm;ukuxhathisa umthamo>1010Ω-m.Xa ubushushu bufikelela kwi-600℃, iteyiphu ye-mica isenokumelana okuphezulu kokugquma kokugquma>10MΩmm2.
• Ngokomda ohlukeneyo wokumelana nomlilo wendlela yebhasi ephikisayo, amanyathelo athathwe ngumaleko wokugquma ubushushu nawo ahluke.Ukuba i-busway idinga ukuhamba ixesha elide kunye nombane, umaleko wokugquma ubushushu udla ngokufakwa ngqo emoyeni ukuze ungachaphazeli ukutshatyalaliswa kobushushu ngexesha lokusebenza kwendlela yebhasi, kwaye xa umgaqo webhasi ungaqhelekanga ukusetyenziswa kwamandla kaxakeka. kuphela, umda wayo wokumelana nobushushu uphezulu kwaye umaleko wokugquma ubushushu kufuneka uzaliswe ngoboya be-silica, izinto zoboya be-silica ezikhethiweyo kule ndlela yebhasi ye-refractory ihambelana ne-GB3003 "i-common aluminosilicate refractory fiber mat" umgangatho, umxholo wayo we-AL2O3 + SiO2 ufikelela kwi-96% , ubushushu bokusetyenziswa okuqhubekayo yi-1050℃, ^ubushushu bokusetyenziswa okuphezulu bufikelela kwi-1250℃.
• Xa umlilo uvela ngaphakathi kwe-3 ~ 5 imizuzu, i-coating iqala ukuphosa i-foam kwaye ikhulise, iyenze i-heat insulation layer, kwaye i-thermal conductivity iyanda ngokukhawuleza, okunciphisa ngokufanelekileyo ukuhanjiswa kobushushu.Zonke izalathisi zentsebenzo ye-coating refractory esetyenziswe kule ndlela yebhasi ye-refractory ihambelana nomgangatho wesizwe we-GB14907-94.
• Ukuze kuhlangatyezwane neemfuno ezichasayo, ibhloko yokwahlukana kwesigaba kunye nebhloko yokwahlula ngokudibeneyo yenziwe ngezinto ze-ceramic ezichasene nobushushu obuphezulu, obunomxholo we-Al2O3 ongaphezulu kwe-95% kwaye inezi mpawu zilandelayo ze-dielectric kunye nemishini phantsi kweemeko eziqhelekileyo: amandla e-dielectric. ≥13kV/mm ukumelana nomthamo>20MΩ-cm amandla aguquguqukayo ≥250MPa.I-ceramic iyasebenza ngokukodwa ekuxhathiseni ubushushu, kwaye ukunyanzeliswa kwe-insulation elinganisiweyo > 10MΩ xa ubushushu bufikelela kwi-900 ° C.Ngenxa yokuzinza okulungileyo kwe-ceramic, akukho ngxaki yokuguga kwezinto zokufakelwa, ngaloo ndlela ukwandisa ngokufanelekileyo ubomi benkonzo yendlela yebhasi.
• Iimveliso ezinobume bendalo: Kwimeko yomlilo, akukho rhasi enetyhefu ephuma kwindlela yebhasi, kwaye akukho kutsha kwesibini okwenziweyo, okusisizukulwana esitsha semveliso yombane ehambelana nokusingqongileyo.
• Iingcingo eziguquguqukayo: Ujongano lweplagi yebhasi lusetwe ngokuguquguqukayo, kwaye kulungele ukuzoba ngaphandle kwesebe langoku.Ujongano lweplagi nganye lunokufakwa kwiibhokisi zeplagi zamandla ahlukeneyo, kwaye isikhonkwane seplagi yebhokisi yeplagi nayo yenziwe ngesixhobo seceramic ukumelana nobushushu obuphezulu ukuqinisekisa ukuba amandla anokutsalwa ngaphandle ngokutyibilikayo xa kunomlilo.
• Uluhlu lwe-NHCCX lwe-refractory busway luphumelele ngempumelelo uvavanyo lohlobo lweSizwe loLawulo lweSixhobo soMgangatho woLawulo lweSixhobo, iZiko loHlolo kunye noVavanyo kunye novavanyo oluchasayo lweZiko leSizwe loVavanyo lweMpahla yoLwakhiwo lweMichiza, kunye nokusebenza kwalo kombane, ukusebenza koomatshini kunye nokusebenza kobuqhophololo konke kusekhaya ^ inqanaba ngokophando.
