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 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. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

            真空斷路器的二次技術從傳統轉向現代化

            真空斷路器的二次技術從傳統技術轉向現代技術,現代二次技術采用了機電一體化技術,電一體化技術是建立在微電子技術、信息傳感技術、計算機控制技術、伺服驅動技術及精密機械技術等高度發展之上的綜合技術。

            機電一體化用在開關設備上,把計算機加進機械系統,使開關系統有了“大腦”,再加進“傳感器”采集信息,用光纖傳導信息使開關系統有了“知覺”,大腦根據知覺作出判定與決定,使系統有了“智能”。因此現代二次技術使之開關設備智能化。

            開關設備的智能化可通過連續檢測,確切了解運行狀況作趨勢分析、識別存在的故障,從而采取必要的措施防患于未然,改以往的“定期檢驗”為“狀態檢驗”,從而進步設備的利用率和節省檢驗用度。

            真空斷路器之所以為眾多廠家青睞,除產量大、覆蓋面廣之外,首要原因是由于真空技術、真空工藝、滅弧室制造技術的不斷進步,使真空斷路用具有優異的電性能和機械性能,能滿足不同用戶的不同要求。另一個重要原因,是它對環境友好,在人們普遍注重環保的今天,這點尤為重要。

            在真空斷路器中,不產生分解物,由于在這里開斷時只產生金屬蒸汽。真空滅弧室盡對密封釬焊,不會與環境相互影響。污穢、灰塵及潮氣均不能進進滅弧,這就避免了任何的氧化。滅弧室的所有材料均以潔凈的狀態保持在整個壽命期間。
