Calculation and Characteristic Analysis of Critical Breakdown Field Strength of SF_6 and the Mixtures

ZHAO Hu,LI Xingwen,JIA Shenli(State Key Laboratory of Electrical Insulation and Power Equipment,Xi'an Jiaotong University,Xi'an 710049,China)  
The reduced critical electric breakdown field(E/N)cr of SF6 and its substitute or mixtures gets very crucial for electrical breakdown evalution.The(E/N)cr of SF6 is investigated under 0.4 MPa and 0.8 MPa respectively,and over the temperature range of 300 to 3 000 K,by solving the two-term Boltzmann equation.The results show that the(E/N)cr of SF6 decreases with increasing temperature,and the decreasing rate depends on the SF6 decomposition rate;at temperature within 1 500 and 2 500 K,the(E/N)cr of SF6under 0.8 MPa is evidently higher than that under 0.4 MPa,however almost equal between 0.8 MPa and 0.4 MPa at other temperature.The calculations for(E/N)cr of SF6-CF4、SF6-CO2、SF6-O2、SF6-CH4、SF6-C2H6 and SF6-CHF3 under 300 K indicate,when x(SF6) in mixture is over 10%,the(E/N)cr of all these mixtures changes approximately linearly with x(SF6);among these gases,the(E/N)cr of CF4 and O2 approaches to the highest;the(E/N)cr of SF6-CF4 and SF6-O2 closely appears,and both higher than that of the others.And r,the ratio of the critical breakdown field of SF6 to that of a gas mixture,is introduced to conclude that under proper pressure and mixing ratio,the critical breakdown field of a gas mixture becomes equivalent to SF6.
