依据SF6的耐电强度设计混合气体绝缘电器

Calculation of dielectric strength of SF 6 gas mixtures via dielectric strength of SF 6 gas

对于同一电器设备，以ＳＦ６气体的耐电强度为基准，利用有关的临界耐电强度（ＥＰ）０和优异值Ｍ，分别计算了ＳＦ６／Ｎ２和ＳＦ６／ＣＯ２混合气体的耐电强度．实际测试表明，计算值与相应测试值的偏差小于±１０％

On the basis of the discharge onset voltages of SF 6 gas, the discharge onset levels of SF 6/N 2 and SF 6/CO 2 gas mixtures have been directly calculated via the relevant limiting field (EP 0) and the relevant figure of merit M data. The predicted levels are observed and the deviation of the calculated values from the measured values is less than ±10%.
