摘要
电力谐波的“谐波污染”已成为一种社会公害 ,归纳了电力谐波的危害性 .对微机类非线形负荷所产生的谐波进行了谐波分析 ,得出即使三相负荷完全平衡 ,中性线中的电流也比相电流大得多 .界定不超标 。
Pollution of electric power harmonic has become a sort of social effects of pollution. This paper concludes the harmfulnees of harmonic, analyses the harmonic taken by the nonlinear load of microcomputer, deduces that the current of neutral line is bigger than the phase electric current even if the triphase load is balanced entirely, and confirms the permission value without exceeding standard and the proportional of the nonlibear load.
