Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following London Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of staying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yes," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won the globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.

断路器“拒合”情况解析

2019/9/17 8:13:30      点击:

pk10开奖结果现代电气设备的缺点率现已非常低了,但在长期的运转当中,必定还是会偶尔出现缺点的情况。

  关于断路器来说,“拒合”情况是其所有缺点中出现比较多的,这种情况基本上是在合闸操作和重合闸过程中发作的,缺点危害性较大。

  举个比方,出现意外事故时,处处断水断电,那么就需要投入备用电源,假设这时候备用电源的断路器拒绝合闸,那么就会扩大事故了。

  判断断路器“拒合”的原因及处理办法一般可以分三步:

  1.查看前一次拒绝合闸是否因操作不当引起,用控制开关再从头合一次;

  2.若合闸仍不成功,查看电气回路各部位情况,以承认电气回路是否有缺点。

  查看项目是:合闸控制电源是否正常,合闸控制回路熔断器和合闸回路熔断器是否杰出,合闸接触器的触点是否正常等;

  3.假设电气回路正常,断路器仍不能合闸,则说明为机械方面缺点,应停用断路器,报告调度安排检修处理。

  要记住一点,若非专业的技术人员,在断路器发作“拒合”时不要进行盲目处理,稍不当心就可能会导致电路器自身的元件损坏,一定要等待专业人员进行修正处理。
