摘要
对c-C_4F_8/CO_2混合气体的绝缘子沿面闪络性能展开研究,得到了在不同气压、不同电压类型下不同混合比例的c-C_4F_8/CO_2的沿面闪络电压,与CO_2和SF_6的沿面闪络电压进行对比,并观测实验后的绝缘子。结果表明:在工频电压和雷电冲击电压下,c-C_4F_8含量和气压是影响c-C_4F_8/CO_2沿面闪络性能的重要因素;在0.10MPa下,c-C_4F_8含量为30%的c-C_4F_8/CO_2的沿面闪络电压为SF_6的80%;在0.30 MPa下,30%含量的c-C_4F_8/CO_2沿面闪络电压约为0.10 MPa下SF_6的1.4倍,但多次实验之后绝缘子出现损坏。
The insulator surface flashover properties of c-C4F8/CO2 mixed gas were studied, and the surface flashover voltage of c-C4F8/CO2 with different mixing ratio under different pressure and different types of voltage was obtained and compared with that of CO2 and SF6. And the insulators after tests were observed. The results show that the content of c-C4F8 and pressure is the important factor influencing the surface flashover voltage of c-C4F8/CO2 under power frequency voltage and lightning impulse voltage. At the pressure of 0.10 MPa, the surface flashover voltage of c-C4F8/CO2 mixed gas with 30% of c-C4F8 is 80% of that of pure SF6. At the pressure of 0.30 MPa, the surface flashover voltage of c-C4F8/CO2 mixed gas with 30% of c-C4F8 is 1.4 times bigger than that of pure SF6. After many experiments,the insulator was damaged.
