| 摘 要： | 文章对滤波电路电容器的联接方法进行分析，得出联接方法对谐波效果有很大影响的结论。尤其是零序谐波，采用角型连接的电容器，没有滤波作用。目前大部分厂商采用角型连接电容器串接14．5％电抗器滤除3次谐波，其实作用甚微。提出了解决方法和需注意事项。

| Abstract: | The paper analyses the join method of filter circuit capacitor which result in tremendous influence on the impact of harmonic, especially the Zero-sequence harmonic. There is no filtering function to adopt capacitor of angle glaucoma. At present most of manufacturers filter 3rd harmonic by using angle glaucoma connection capacitor to connect 14.5 reactance, in fact there is only slight effect. The paper provides answers and points of attention as well. |
