Hluav taws kub-resistant Low-voltage Enclosed Busway

Xaiv cov rwb thaiv tsev thiab cov ntaub ntawv refractory nrog kev ua tau zoo heev

• Mica daim kab xev raug mob los ntawm kab tooj liab ntawm cov neeg tsav tsheb npav ua raws li JB / T5019 ~ 20 "cov khoom siv hluav taws xob rwb thaiv tsev mica" thiab JB / T6488-1 ~ 3 "mica daim kab xev" qauv.Mica daim kab xev muaj qhov yooj yooj yim thiab siab kub tsis kam thiab zoo dielectric zog thiab txhua yam khoom nyob rau hauv ib txwm mob: dabtsi yog khoov zog ≥180MPa;dielectric zog ≥35kV/mm;Volume resistivity> 1010Ω-m.Thaum qhov kub nce mus txog 600 ℃, mica daim kab xev tseem muaj kev tiv thaiv kev ua haujlwm siab rwb thaiv tsev> 10MΩmm2.
• Raws li qhov sib txawv ntawm cov hluav taws kub tsis kam ntawm cov tsheb thauj mus los ntawm refractory, cov kev ntsuas coj los ntawm cov txheej txheem cua sov kuj txawv.Yog hais tias lub tsheb thauj mus los yuav tsum tau khiav mus ntev nrog hluav taws xob, lub tshav kub rwb thaiv tsev txheej feem ntau yog ncaj qha insulated nrog huab cua kom tsis txhob cuam tshuam lub tshav kub dissipation thaum lub sij hawm ua hauj lwm ntawm lub busway, thiab thaum lub busway tsis nquag nquag siv hluav taws xob thaum muaj xwm ceev. Tsuas yog, nws qhov kev txwv tsis pub muaj cua sov siab dua thiab cov txheej txheem rwb thaiv tsev kub yuav tsum tau ntim nrog silica wool, silica wool cov ntaub ntawv xaiv rau lub tsheb thauj mus los no ua raws li GB3003 "hom aluminosilicate refractory fiber lev" tus qauv, nws cov ntsiab lus AL2O3 + SiO2 ncav cuag 96%. , qhov kub siv tas mus li yog 1050 ℃, ^ siv kub siab txog 1250 ℃.
• Thaum qhov hluav taws kub tshwm sim li ntawm 3 ~ 5 feeb, cov txheej pib ua npuas dej thiab nthuav dav, tsim cov txheej txheem rwb thaiv tsev kub, thiab thermal conductivity nce sai, uas txo cov cua sov hloov mus.Tag nrho cov kev ua tau zoo ntawm cov txheej txheem refractory siv nyob rau hauv lub tsheb thauj mus los refractory yog raws li lub teb chaws tus qauv GB14907-94.
• Txhawm rau ua kom tau raws li cov kev xav tau ntawm cov refractory, cov theem kev sib cais thiab cov kev sib cais sib cais yog ua los ntawm cov khoom siv kub kub resistant ceramic, uas muaj cov ntsiab lus Al2O3 ntawm ntau tshaj 95% thiab muaj cov nram qab no dielectric thiab mechanical zog nyob rau hauv ib txwm tej yam kev mob: dielectric zog. ≥13kV/mm ntim resistivity> 20MΩ-cm flexural zog ≥250MPa.cov ceramic yog tshwj xeeb tshaj yog zoo nyob rau hauv kub tsis kam, thiab ntsuas rwb thaiv tsev tsis kam yog> 10MΩ thaum kub txog 900 ° C.Vim muaj kev ruaj ntseg zoo ntawm cov ceramic, tsis muaj teeb meem kev laus ntawm cov khoom siv rwb thaiv tsev, yog li ua kom muaj txiaj ntsig zoo rau kev pab cuam lub neej ntawm lub tsheb npav.
• Environmentally friendly khoom: Nyob rau hauv cov ntaub ntawv ntawm hluav taws kub, tsis muaj toxic gas yog emissions los ntawm lub tsheb npav, thiab tsis muaj lwm yam combustion yog tsim, uas yog ib tug tshiab tiam ntawm environmentally phooj ywg khoom hluav taws xob.
• Flexible wiring: Busway plug interface yog teeb tsa yooj yim, thiab nws yooj yim los kos tawm cov ceg tam sim no.Txhua qhov txuas txuas tuaj yeem muab tso rau hauv cov thawv sib txawv, thiab lub thawv ntsaws ntsaws ntsaws ruaj ruaj kuj yog ua los ntawm cov khoom siv kub kub resistant ceramic kom ntseeg tau tias lub zog tuaj yeem rub tawm tau zoo thaum muaj hluav taws.
• NHCCX series refractory busway tau ua tiav hom kev xeem ntawm National Electric Control Equipment Quality Supervision, Inspection and Testing Center thiab refractory test of National Chemical Building Material Testing Center, thiab nws cov kev ua tau zoo hluav taws xob, kev ua haujlwm zoo thiab kev ua haujlwm ntawm refractory yog tag nrho ntawm cov khoom siv hauv tsev. qib raws li kev tshawb nrhiav.
