| 摘 要： | 某发电厂200MW发电机转子回路采用线性电阻灭磁,放电间隙+过电压击穿保险作为转子过电压保护,这种传统励磁回路设计和选用的设备在实际运行中缺陷明显。目前,国内已有许多机组采用高性能氧化锌电阻(ZnO)作为转子灭磁电阻和过电压保护,实用效果显著。

| Abstract: | Linear resistance demagnetization is adopted on rotor return circuit of 200MW generator in a power plant. Combined span of electric discharge with safeguard of over-voltage puncture as over-voltage protective device,there are obvious defects in the operation of the traditional design and equipment chosen for excitating return circuit. Today,high-quality ZnO resistances are adopted as demagnetization resistance and over-voltage preservative device on many domestic generator units. All this achieve good resul... |
