摘要:
爲了尋找SF6的替代氣體,文中對極不均勻電場中的10%~30%CF3I/CF4混合氣體在不同極間距(5~35 mm)和不同氣壓(0.1~0.3 MPa)下的工頻擊穿特性進行了實驗研究。結果發現,CF3I/CF4混合氣體的工頻擊穿電壓隨著極間距的增大而近似線性增大,但是其隨氣壓升高和CF3I體積分數的升高均表現出“駝峰”現象。與SF6相比,CF3I/CF4混合氣體的工頻耐壓水平在它的59%~120%之間。綜合考慮,15%~20%CF3I/CF4混合氣體可以作爲SF6替代氣體在合適的電氣設備中使用。
Abstract:
In order to look for SF6 alternatives, this paper has experimentally researched AC breakdown characteristics of 10%~30%CF3I/CF4 gas mixtures with different electrode gap distances(5~35 mm) and different gas pressures(0.1~0.3 MPa) in condition of extremely non?uniform electric field. The results show that AC breakdown voltage of CF3I/CF4 gas mixtures nearly linearly increases as electrode gap distance increases, but the voltage performs the well?known N shapeas the gas pressures and the ratio of CF3I increase. Compared with SF6, power frequency withstand voltage of CF3I/CF4 gas mixtures is between 59%~120% of that of SF6. Taking every factor of account, 15%~20% CF3I/CF4 gas mixtures can be regarded as SF6 alternatives to be applied in some proper electrical apparatus.
