假如7PS雷击后造成高压部分全停电或部分停电对其进行处理?

答案

参考答案:

处理

立即汇报值长;

检查表计、信号指示、继电保护动作掉牌情况、开关动作情况及其它现象,正确判断事故范围和性质,并解除报警。

如果事故对人身和设备安全有严重威胁时,应立即解除这种威胁(迅速切除故障点,使之与其它供电设备隔离)。

因雷击造成高压部分全停电的,若进线带电,立即重合闸一次,能合上则按高压全失电处理;一次合不上,不得合第二次。

若进线带电,如果两段都不能合上,应将所有开关断开,然后检查高压母线的绝缘,绝缘良好的可逐步恢复送电,具体按高压全失电处理。

若进线不带电,应立即联系上方检查母线带电情况,并及时送出进线回路电源,然后按高压全停电的情况处理。

因雷击造成一段失电的,可按照部分停电的情况处理。

因雷击造成设备损坏的,应立即切除这部分设备,并及时联系相关单位及人员处理。

                                                             How Long Can People Live?
       She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the
neighborhood on her 121st birthday.
        When it comes to long life, Jeanne Calment is the world's recordholder. She lived to the ripe old age
of 122. So is 122 the upper limit to the human life span (寿命)? If scientists come up with some sort of pill
or diet that would slow aging, could we possibly make it to 150-or beyond?
        Researchers don't entirely agree on the answers. "Calment lived to 122, so it wouldn't surprise me if
someone alive today reaches 130 or 135," says Jerry Shay at the University of Texas.
        Steve Austad at the University of Texas agrees. "People can live much longer than we think," he says.
"Experts used to say that humans couldn't live past 110. When Calment blew past that age, they raised the
number to 120. So why can't we go higher?"
        The trouble with guessing how old people can live to be is that it's all just guessing. "Anyone can make
up a number," says Rich Miller at the University of Michigan. "Usually the scientist who picks the highest
number gets his name in Time magazine."
       Won't new anti - aging techniques keep us alive for centuries? Any cure, says Miller, for aging would
probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the
life span of mice by 50 percent at most. So, if the average human life span is about 80 year, says Miller,
"adding another 50 percent would get you to 120." 
       So what can we conclude from this little disagreement among the researchers? That life span is flexible
(有弹性的), but there is a limit, says George Martin of the University of Washington. "We can get flies to
live 50 percent longer," he says. "But a fly's never going to live 150 years." Of course, if you became a new
species (物种), one that ages at a lower speed, that would be a different story, he adds. 
       Does Martin really believe that humans could evolve (进化) their way to longer life? "It's pretty cool to
think about," he says with a smile.
