Statistical Analysis on Variation Coefficient of Flashover Voltage of Naturally Contaminated Insulators
摘要
Abstract
This paper performs a statistical analysis on distribution rules of variation coefficient of flashover voltage of naturally contaminated insulators obtained by average set-up method and comparatively analyzes the distribution rules and those of variation coefficient of artificial contamination flashover voltage. The results show that the upper confidence limits of variation coefficient of natural pollution flashover voltages , which are obtained with the average step-up method, have a maximum of 0.3101, and the variation coefficients approx-imately comply with normal distribution , with the expectation value of 7.45%, and its upper limit is 8.14%in 95% confidence interval, which is almost consistent with the results obtained with up-and-down method. In general, the dispersity of natural contamination flashover voltage is greater than that of artificial contamina-tion flashover voltage.关键词
