摘要
发电机长期非全相运行会受到严重损害,小浪底水电站在生产运行期间曾多次出现220 kV开关非全相保护动作,通过分析电气控制回路、检查开关机械结构和采取必要的试验等手段,成功找出了故障原因,并有效地解决了问题。
The non-full phase operation of generator for a long time can seriously damage generator. The Xiaolangdi Hydropower Station occurred many non-full, phase protection actions of 220KV switch during its production and operation period. Through analyzing electric control circuit, checking the mechanical structure of switch, and taking essential experimental means, we successfully find out the reasons of failure and solve this problem effectively.
