摘要
按照相应国家标准规定,大型发电机定子绕组的起晕电压要求大于22 kV,但有些国产发电机存在着起晕电压低的缺陷,给机组安全运行带来隐患。结合实际发电机的具体情况,制定了处理对策。通过检验和运行考验,证明了处理方案的正确性。
The corona voltage of stator windings for a large capacity of generator should be over 22 kV according to relevant national codes in China, however, the corona voltage of stator coils for generators domestic is lower, which has some hidden troubles in safe operation. Some countermeasures were proposed to solve them focusing on actual situation of generator, the actual operation and measured results showed that this means is practical and feasible.
