浅谈谐波对医院电力运行的危害

Talking about the Harm of Harmonics to Hospital Electric Power Operation

随着医疗技术的飞速进步和医院自身的发展需求,越来越多精密的、对电能质量敏感的医疗设备被投入使用,其中不乏使用大量电力电子元器件的医疗放射影像设备,而这些非线性负载又不可避免地产生大量谐波,对电能质量造成严重危害。这个矛盾给医院实际电力运行带来许多问题,同时也对变压器等电力设备的安全运行造成影响。该文结合对配电室低压进线柜电能质量的分析,阐述电力运行过程中谐波带来的危害。

With the rapid advancement of medical technology and the development needs of hospitals, more and more sophisticated medical equipment sensitive to power quality has been put into use, including medical radiography equipment using a large number of power electronic components. Non-linear loads inevitably generate a large number of harmonics,which cause serious damage to power quality. This contradiction brings many problems to the actual operation of the hospital, and also affects the safe operation of power equipment such as transformers. This paper combines the analysis of power quality of low-voltage incoming cabinets in power distribution rooms to illustrate the hazards caused by harmonics during power operation.
