发电机轴电流危害及治理措施探讨
|
摘要
可持续发展理念的深化,使得清洁能源的开发利用受到了社会各界的广泛关注,水电凭借着本身成熟的技术以及高效、清洁、可再生的优势,在我国得到了快速发展。而在水轮发电机运行中,如果转子与定子无法保持完全通信,则在运行过程中可能引发相应的轴电流,对发电机的正常稳定运行产生影响。本文从水轮发电机轴电流的危害出发,结合具体案例,对轴电流治理措施进行了分析和讨论。
With the deepening of the concept of sustainable development,the development and utilization of clean energy has been widely concerned by all sectors of society. Hydropower,with its mature technology and advantages of high efficiency,clean and renewable,has been developing rapidly in China. In the operation of hydro-generator,if the rotor and stator cannot maintain complete communication,the corresponding axial current may be triggered during the operation,which will affect the normal and stable operation of the generator. Based on the harm of shaft current of hydro-generator,this paper analyzes and discusses the measures to control shaft current combining with specific cases.
