配电电缆试验方法的研究现状和发展趋势
Research Status and Development Trend of Distribution Cable Test Methods
摘要
Abstract
Distribution cable is an important part of equipment of power grid.Partial discharge and overall insulation aging due to its insulation defects are main reasons leading the the cable failures.For preventing cable failures and ensuring safe and reliable operation of the distribution power grid,it is of great significance to study the test method of distribution cable.In this paper,the existing test standards both at home and abroad are summarized,the princi-ples and test specification of various test methods for distribution cable,including power frequency voltage test,se-ries resonance voltage test,oscillation wave voltage test,very low frequency sinusoidal wave voltage test,very low fre-quency cosine rectangular wave voltage test,are described.And the study status and the existed problem of the oscil-lation wave and very low frequency voltage test method is reviewed in detail and the partial discharge characteristic of cable is discussed.Finally,the prons and cons of the test method mentioned above is summarized and its main de-velopment trends of their application in the insulation condition diagnosis of distribution cable are discussed.关键词
