摘要
以大连马场220kV变电站为例,分别对一号主变高低压侧电压畸变率、闪变电压和谐波电流进行了测试,以测试结果为依据对一号主变噪声异常现象进行了分析,从而确定了主变产生异常噪声的原因,并从制造工艺和结构设计方面提出了抑制噪声的具体措施。
Based on 220kV power station of Stud Farm in Dalian , the No.1 transformer high voltage side voltage distortion, voltage flicker and harmonic current are tested respectively. According to the test consequence, the unusual noise phenomenon of main transformer is analysed. The reason is determined. The specific measures for suppressing noise are presented.
