摘要
某电厂的一台300 MW双水内冷发电机,在运行中发生转子接地事故,造成转子绕组绝缘部分烧损、大轴磁化。通过对发电机抽转子后的现场分析和大轴退磁,阐述了可能的事故首发原因和事故发展过程,同时提出为防止类似事故发生应采取的措施。
If a rotor ground accident of one 300 MW double-water internal cooling generator occurs in an electric power plant, it can cause breakage of rotor winding and magnetization of shaft. This paper deduces the possible first-occuring reason and the process of the accident through The analysis and demagnetization of the shaft after drawing the rotor and offers the measures to prevent such event fromhappening again.
