问题 10kV变电所的电容器组应装设放电装置,请问使电容器组两端的电压从峰值(1-414倍的额定电压)降至50V所需的时间,高、低压电容器分别不应大于下列哪组数值?(电容器组为手动投切)() (A)5min,1min(C)3min,3min (B)4min,2min(D)2min,4min
选项
答案 A
解析 依据:《10kV及以下变电所设计规范》(GB50053-1994)第5.1.3条,此题不严谨,《并联电容器装置设计规范》(GB50227-2008)上相关规定与之不一致,不过此题明显考查GB50053-1994的规范原文,因此建议选A。

相关内容:变电所,电容器,组应,放电,装置,两端,电压,峰值,1-414倍,时间,低压,哪组

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
