谐波电流的危害及对策研究

The Harm Done by Harmonic Electric Current and Preventive Measures Against it

随着工业化、自动化程度的普及和提高,对供电质量和安全的要求越来越高,因而谐波电流的危害不容忽视。探讨了谐波电流的产生原因,从影响电力系统正常工作、干扰电子设备、影响电磁设备运行、引起火灾爆炸事故等几个方面分析了谐波电流的危害,提出改善供电系统结构、装设滤波器、增大中性线截面、调整变压器接线方式等对策。

With the advancement and the improvement of industrialization and automation, the demand for the stable electricity supply is increasing. As a result, the harms done by harmonic electric current produces cannot be ignored. This paper explores the roots of harmonic electric current, analyzes the harms, and provides the preventive measures.
