Following Londonfl jerseys supplyn 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 swomen nfl jerseystaying 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, "yecheap nfl jerseys wholesales," 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 http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said.

          斷路器“拒合”情況解析

          2019/9/17 8:13:30      點擊:

          現代電氣設備的缺點率現已非常低了,但在長期的運轉當中,必定還是會偶爾出現缺點的情況。

            關于斷路器來說,“拒合”情況是其所有缺點中出現比較多的,這種情況基本上是在合閘操作和重合閘過程中發作的,缺點危害性較大。

            舉個比方,出現意外事故時,處處斷水斷電,那么就需要投入備用電源,假設這時候備用電源的斷路器拒絕合閘,那么就會擴大事故了。

            判斷斷路器“拒合”的原因及處理辦法一般可以分三步:

            1.查看前一次拒絕合閘是否因操作不當引起,用控制開關再從頭合一次;

            2.若合閘仍不成功,查看電氣回路各部位情況,以承認電氣回路是否有缺點。

            查看項目是:合閘控制電源是否正常,合閘控制回路熔斷器和合閘回路熔斷器是否杰出,合閘接觸器的觸點是否正常等;

            3.假設電氣回路正常,斷路器仍不能合閘,則說明為機械方面缺點,應停用斷路器,報告調度安排檢修處理。

            要記住一點,若非專業的技術人員,在斷路器發作“拒合”時不要進行盲目處理,稍不當心就可能會導致電路器自身的元件損壞,一定要等待專業人員進行修正處理。
