二)误操作事故

1994年3月3日,某供电公司220kV某变电站254开关、CT及有关刀闸停电检修,220kV#1母线也停电清扫。15时20分#1母线的工作完成报了竣工,15时29分中调令将220kV#1母线由检修转运行。在15时55分至16时25分期间,进行了投运#1母线的各项操作。16时12分,254开关的检修工作也已完成,向调度报了竣工。在无调度命令的情况下,值班员擅自将254开关合闸送电。因线路对端接地刀闸还没有拉开,造成带地线合开关的恶性误操作事故,幸线路上无人工作,继电保护又正确动作,254开关立即掉闸,未造成人身伤害和设备损坏的严重后果。

Teaching my first child, Danae, to share her toys was the biggest challenge. To   36  this, we started inviting other children to play, which could help Danae discover that it’s   37  to share with others – a lesson I needed to   38  myself as well, as it   39 .
One evening Danac had   40 a friend, Natalie, to play with her. Their favorite was a children’s   41  game called Go Fish. That evening,   42  Natalie left, Danae came to me and said, “Mommy, I’d like to give these to Natalie tomorrow. They’re her favorites.”
She help up three cards from the Go Fish game. I tried to   43  that I didn’t want her to give them away because then our   44  wouldn’t be complete. “But I really want her to have them!” Danae   45 . I thought perhaps she didn’t understand that when she gave something away, it was gone   46 . So I tried again, saying, “  47  you give the cards to her, you can’t   48 them back tomorrow.”
A look of   49  came over Danae’s face. For a moment I was happy that she seemed to   50 . But then she smiled and said. “Well, that’s okay, I want her to have them anyway.”
What could I say to that? I sat   51  for a moment and then I realized I had been trying for so long to   52  her to share. Did it   53  that our Go Fish set would be   54 ? What mattered was that my daughter was learning the   55  of giving, that she was thinking about others instead of herself, and that she was trying to make her friends happy. Isn’t that what life is all about?
