摘　　要：有色冶炼厂不可避免地大量使用谐波源设备,而谐波的存在又严重危害了供电网络和用电设备的安全。本文主要介绍了低损耗三调谐滤波器的基本原理及参数计算,及该滤波器在吉首某冶炼厂谐波治理和无功补偿改造项目中的应用,并对在工程中遇到的一些需要注意的问题进行了分析并提出了解决措施。There are many harmonics source equipment in non-ferrous smelting works. The existence of harmonics seriously harms to safety of power grid and electric equipment. Principle and parameter calculation of three-tuned filter with low loss are described in detail. The filter has been applied to harmonics suppression and reactive power compensation of a certain smelting works in Jishou. Some prob- lems which need to pay attention in project are analyzed and solutions are provided.
