摘要
在变电站运行值班中,对于中性点不接地系统值班员常会遇到一些电压表输出不平衡的情况。若我们对这方面认识不足,往往会因为查找时间过长而耽误送电,因电压不平衡而误认为接地情况者,找不到问题之所在,却做许多无用功;另一方面也可能因为未能及时找到接地点,而引起扩大事故。所以,就这个问题有必要进行一些分析探讨。
in the operation of substation on duty,for the neutral point ungrounded system attendant will often encounter some voltage meter output unbalanced situation.If we are to this understanding is insufficient,often because of search time is too long and delay of transmission,because of voltage unbalance and mistakenly believe that the ground situation,find the problem,but do many useless;on the other hand,may have failed to find a ground,caused by expanding the accident.So,on this problem is necessary for some analysis and discussion.
