谐波对电器设备的危害及影响

Harmfulness and Impact of Harmonics on Electrical Equipment

经济和社会的快速发展促进了我国电力行业的不断进步,我国智能电网建设日益加快,电力技术的提升是电网运行的重要保障,电力系统中存在着大量的非线性特性的用电设备,导致了电力运行中存在大量的谐波源.在正常状态下,供电电压波形呈现的是正弦波,但是因为谐波的存在,实际波形偏离了正弦波.谐波对各种电器产生了重要的影响,谐波带来的危害影响电网正常运行.谐波处理需要技术上的提升,需要综合治理.文章以谐波对电气设备的危害及影响为研究核心,分析阐述了谐波的原理,明确了谐波对电气设备的危害和影响,提出了规避谐波造成损害的思路和措施.

The rapid economic and social development has promoted the continuous progress of China’s power industry.The construction of smart grids in China is accelerating.The improvement of power technology is an important guarantee for the operation of power grids.As a result,there are a lot of harmonic sources in power operation.In the normal state,the power supply voltage waveform presents a sine wave,but because of the existence of harmonics,the actual waveform deviates from the sine wave.Harmonics have an important impact on various electrical appliances,and the harm caused by harmonics affects the normal operation of the power grid.Harmonic treatment needs to be technically improved and comprehensive management is required.This article takes the harm and impact of harmonics on electrical equipment as the core of research,analyzes and explains the principle of harmonics,clarifi es the harm and impact of harmonics on electrical equipment,and proposes ideas and measures to avoid damage caused by harmonics.
