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

      1. 電力變壓器送電

        電力變壓器 A、新變壓器除廠家進(jìn)行出廠試驗外,安裝竣工投運(yùn)前均應(yīng)現(xiàn)場吊芯檢查;大修后也一樣。(短途運(yùn)輸沒有顛簸時可不進(jìn)行,但應(yīng)作耐壓等試驗)。
        B、變壓器停運(yùn)半年以上時,應(yīng)測量絕緣電阻,并做油耐壓試驗。
        C、變壓器初次投入應(yīng)作≤5次全電壓合閘沖擊試驗,大修后為≤3次同時應(yīng)空載運(yùn)行24h無異常,才能逐步投入負(fù)載;并做好各項記錄。目的是為了檢查變壓器絕緣強(qiáng)度能否承受額定電壓或運(yùn)行中出現(xiàn)的操作過電壓,也是為了考核變壓器的機(jī)械強(qiáng)度和繼電保護(hù)動作的可靠程度。
        D、新裝和大修后的變壓器絕緣電阻,在同一溫度下,應(yīng)不低于制造廠試驗值的70%。
        E、為提高變壓器的利用率,減少變損,變壓器負(fù)載電流為額定電流的75~85%時較為合理。
