| 摘 要： | 基于局部电弧—剩余污层串联模型及相关结果,利用假设条件和相关参数间的关系,导出了污闪电压与等值盐密及其它多个参数间的理论关系式,该式表明污闪电压与等值盐密是幂函数关系,其中系数 K受多个参数影响,而指数P只与电弧常数n 有关。应用该式表达和解释了若干实验结果,给出了通过 P计算n 的方法。该理论式可用于污闪问题的分析研究。

| Abstract: | On the basis of the model of local electric arc in s er ies with residual dirt-layer, the theoretical relation between pollution flasho ver voltage (PFV) and equivalent salt deposit density (ESDD) as well as other se veral parameters is derived with the help of some hypothesis and related functio ns and the results show that the function relation between PFV and ESDD is a pow er function, in which the coefficient K is related to many parameters but the ex ponent P is only related to the electric arc constant n. Some experimental resul ts are successfully explained by using the theoretical relation. In addition, th e method for calculating electric arc constant n by way of exponent P is given. The function can be used for research and analysis on pollution flashover. |
