摘要
分析了谐波对配电线路发热的影响及谐波环境下并联电容器组进行无功功率补偿造成谐波放大的原因,提出了谐波环境下导线截面的选择、无功无源补偿装置合理选型的一般步骤与方法以及电力变压器等设备的选型要点,以待提高建筑电气设备运行的安全性与可靠性.
This paper analysee the effect of harmonic wave on the heat generation in distributionlime and the reason why the reactive power compensation of the array of shunt capacitors under the harmonic wave circumstance causes harmionic magnification. Based on this analysis and for the purpose of improving the security and reliability of the operating electricequipment in building, this paper proposes the general process and method of selecting of the cross section of wire surrounded by harmonic wave and the rational lectotype for the reactive and passive compensation set. And this paper also proposes the key points of lectotype for electric equipment such as electrical transformer and so on.
