126kV-550kV PTFE nozzle

Na ɗaya na ɗaya na ƙaramin politetrafluoroethylene (PTFE) ta 126kV-550kV shine muhimman ƙaramin ziyarar tsakiyar tsakiyar kungiyar (kamar LW30-126, LW36-126, duka), da kyauccinsa yana haifi shi da kayan tsayi da lokacin da ake amfani da kungiyar. A nan ne bayanai masu ilimi mai zurfi:
1、 Muhimman abubuwan da suka bukata
Jirgin Samun Karamin Rarrabawa da Jirgin Yawanci
Karamin 126kV ya kamata a yi damar rarraba mai tsayi a 550kV, karamin 252kV ya kamata a yi damar rarraba mai tsayi a 950kV, kuma samun karamin rarrabawa ≤ 15kV/mm
Lokacin da ake amfani da shi da kyauccinsa ya kamata ya taimaka wa -200 ℃~260 ℃, kuma a lokacin da ya fi shahara da jiki ya kamata ya taimaka wa 300 ℃ (kamar karamin kungiyar LW36-126)
Jirgin Samun Karamin Jiki da Jirgin Haifi Da Dukkar
Ya kamata a yi damar karamin jiki mai tsayi a 50kA, kuma dukkar da ke faruwa a kan karamin kungiyar ≤ 0.1mm/waɗanda
Daga cewa an amfani da PTFE mai inganci da muhimmanci kamar graphite da carbon fiber, ana haifi da dukkar da ke faruwa da 30% zuwa hagu
2、 Abubuwan da Masana'antar
Masana'antar da ake amfani da shi
An amfani da masana'ar molding sintering, hanyar sintering ya kamata a yi damar 360 ℃~380 ℃, damar ya kamata ≥ 10MPa, kuma misali ya kamata ≥ 2.15g/cm ³
Jirgin samun karamin alama mai sararin metal don plasma treatment ko chemical etching
3、 Manufar da Tsari da Kungiyoyi
Manufar da ake amfani da shi
Karamin 126kV an amfani da shi wajen kungiyar cin kasa (kamar modeli LW30-126/3150-40)
Tsari
Yana bukata a duba da GB/T 11022-2020 "Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards"
Bayanin bayyana da ake buƙaci ita yana bukata a yi damar 100 full capacity short-circuit current tests (kamar 40kA/3s)
4、 Manyan Abubuwan da Tattalin Arziki
Haifi da dukkar da ke faruwa
Za a haifi da dukkar da ke faruwa a kan rarraba da gradient material design (kamar PTFE outer layer+silicon carbide inner layer)
