摘要
简要介绍了系统中谐波源的类型,分析了谐波电流在电容器支路中放大、分流、谐振和发生并联谐振的条件;列出了电容器的损耗模型及其与频率间的关系,给出了电容器的介质损失角老化公式及对电容器在谐波条件下的运行进行了分析说明。
The types of harmonic sources of power system are introduced, and wave electric current amplifying, shunts, the resonance, condition connecting the resonance in parallel and impact on condenser in condenser branch road in harmony are analyzed. The model of condenser loss and the relation between frequency and the model are proposed, and the formula of aging of dielectric loss angle of condensers is provided. The condenser which is running under the harmonic voltage is also analyzed.
