摘要
200MW机组传统的6kV厂用电备用电源自动切换装置(BZT)切换时间长,不能满足大型发电机组的厂用电切换的需要,常导致机组停机。文章从机组安全运行的观点出发,分析了传统BZT存在的问题,提出了解决办法。
There are some problems existed in the automatic switching systems, which enlarge the extent of the accident. In the traditional stand-by power automatic switch-in system,the switching time is one of them, which cannot meet the requirement of the automatic switching of house power for large units. For safe operation, the authors analyze the existing problem of traditional BZT system and propose solutions and countermeasures.
