Ubwino

Kusankhidwa kwa zida zotchinjiriza ndi zowumitsa zokhala ndi ntchito yabwino kwambiri

• Tepi ya mica yovulala pamzere wamkuwa wa kondakitala wa basi imagwirizana ndi JB/T5019~20 "mica insulation mica product" ndi JB/T6488-1~3 "mica tepi" miyezo.Tepi ya mica imakhala ndi kusinthasintha kwabwino komanso kukana kutentha kwakukulu komanso katundu wabwino wa dielectric ndi zida zamakina pansi pa chikhalidwe chabwino: mphamvu yopindika ≥180MPa;mphamvu ya dielectric ≥35kV/mm;kuchuluka kwa resistivity> 1010Ω-m.Kutentha kukafika pa 600 ℃, tepi ya mica imakhalabe ndi kukana kwakukulu kwa ntchito yotchinjiriza> 10MΩmm2.
• Malingana ndi malire osiyanasiyana oletsa moto wa basiy refractory, njira zomwe zimatengedwa ndi kutentha kwa kutentha ndizosiyana.Ngati msewu wamabasi uyenera kuyenda kwa nthawi yayitali ndi magetsi, gawo lotenthetsera kutentha nthawi zambiri limatsekeredwa mwachindunji ndi mpweya kuti lisakhudze kutentha kwapanthawi yoyendetsa mabasi, komanso pomwe mabasi sakhala ndi mphamvu zogwiritsira ntchito mphamvu mwadzidzidzi. kokha, malire ake otentha kutentha ndi apamwamba ndipo wosanjikiza kutentha kutentha ayenera kudzazidwa ndi silika ubweya, zinthu silika ubweya wosankhidwa kwa msewu basi refractory zikugwirizana ndi GB3003 "wamba aluminosilicate refractory CHIKWANGWANI mat" muyezo, AL2O3 + SiO2 zili kufika 96% , kutentha ntchito mosalekeza ndi 1050 ℃, ^ mkulu ntchito kutentha kufika 1250 ℃.
• Moto ukachitika mkati mwa mphindi 3-5, zokutira zimayamba kutulutsa thovu ndikukula, ndikupanga wosanjikiza wotenthetsera kutentha, ndipo matenthedwe amatenthedwe amakula mwachangu, zomwe zimachepetsa kutengera kutentha.Ma index onse amachitidwe a zokutira zokanira zomwe zimagwiritsidwa ntchito mumsewu wa basi wokanirazi zimagwirizana ndi muyezo wadziko lonse wa GB14907-94.
• Kuti akwaniritse zofunikira zotsutsana, gawo lolekanitsa gawo ndi chipika cholekanitsa chophatikizana chimapangidwa ndi zinthu za ceramic zosagwira kutentha kwambiri, zomwe zili ndi Al2O3 yoposa 95% ndipo zimakhala ndi dielectric ndi makina otsatirawa pamikhalidwe yabwinobwino: mphamvu ya dielectric. ≥13kV/mm voliyumu resistivity>20MΩ-cm flexural mphamvu ≥250MPa.Ceramic imakhala yogwira mtima kwambiri pakukana kutentha, ndipo kukana kwa kutchinjiriza kuyeza ndi> 10MΩ kutentha kukafika 900 ° C.Chifukwa cha kukhazikika kwa ceramic, palibe vuto la ukalamba la zinthu zotchinjiriza, motero kumakulitsa moyo wautumiki wanjira ya basi.
• Zopangira zachilengedwe: Pakayaka moto, palibe mpweya wapoizoni womwe umatuluka mumsewu wa basi, ndipo palibe kuyaka kwachiwiri komwe kumapangidwa, komwe ndi mbadwo watsopano wamagetsi oteteza chilengedwe.
• Mawaya osinthika: Mawonekedwe a pulagi yamabasi amakhazikitsidwa mosinthika, ndipo ndikwabwino kujambula nthambi yomwe ilipo.Mawonekedwe aliwonse a pulagi amatha kuyikidwa m'mabokosi osiyanasiyana a pulagi, ndipo plug box pin guard imapangidwanso ndi zinthu za ceramic zosagwira kutentha kwambiri kuti zitsimikizire kuti mphamvuyo imatha kutulutsidwa bwino pakayaka moto.
• NHCCX mndandanda refractory busway wapambana mayeso amtundu wa National Electric Control Equipment Quality Supervision, Inspection and Testing Center ndi mayeso oyeserera a National Chemical Building Material Testing Center, ndi magwiridwe ake amagetsi, magwiridwe antchito amakina ndi magwiridwe antchito onse ali kunyumba ^ mlingo malinga ndi kafukufuku.
