摘要
以实验的方法研究了c-C4F8和CF4混合气体在棒-板极不均匀电场下的50 Hz交流绝缘特性,寻找该混合气体最佳混合比、气压和电极间距。说明了实验方法和装置,实验的结果显示5%混合气体在电极间距为20 mm,压强0.3 MPa时,该混合气体是最佳绝缘状态,这个试验结果对该混合气体用作绝缘介质有重要的试验指导意义。
The 50 Hz AC insulation characteristics of c-C4F8 and CF4 hybrid gas in extremely non-uniform electric fields are studied through experiments to find out the optimal hybrid ratio, air pressure, and electrode distance. The results show that the hybrid gas is in its best insulation state with the hybrid ratio of 5%, 20 mm electrode distance, and 0.3 MPa pressure.
