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

        注意事項(xiàng)

        4.1  延時(shí)越短的繼電器越容易整定,實(shí)際準(zhǔn)確度高,故建議優(yōu)先選用。特別是采用0.3秒保護(hù)時(shí)間級差時(shí),應(yīng)選用延時(shí)范圍不大于5秒的繼電器。

        4.2  做延時(shí)整定時(shí),應(yīng)注意兩次通電動作之間,要留有一定的間隔時(shí)間,以確保整定值的準(zhǔn)確度。

        4.3  帶有電流保持回路的繼電器,使用時(shí)注意工作電壓與自保持電流回路同極性 (電壓、電流回路極性見圖3端子接線圖)。如果極性反,易將電流回路觸點(diǎn)損壞。

        4.4  繼電器在工作過程中,應(yīng)定期檢查它的出口觸點(diǎn),若有燒毀,應(yīng)檢查開關(guān)輔助觸點(diǎn)是否斷開過慢。

        4.5  長期工作制的產(chǎn)品,在安裝運(yùn)行和維護(hù)中應(yīng)防止外附電阻及其連接導(dǎo)線接地。

        該系列時(shí)間繼電器(以下簡稱繼電器)作為延時(shí)控制元件,用于電力系統(tǒng)繼電保護(hù)裝置及自動化裝置中,使被控設(shè)備或電路按照預(yù)定的延時(shí)動作。
        主要特點(diǎn)如下:
        a.具有較高的延時(shí)準(zhǔn)確性?梢詫㈦A段式繼電保護(hù)的級差壓縮為0.3s。
        b.可靠性強(qiáng),不存在發(fā)卡拒動的問題,并已取得大量的成功運(yùn)行經(jīng)驗(yàn)。
        c.配置了電流自保持觸點(diǎn),有利于直接接通跳閘回路。
        d.通用性強(qiáng)。該繼電器采用與DS—110系列時(shí)間繼電器相同的外殼,并充分考慮了端子接線與上述繼電器的對應(yīng)關(guān)系。因此,可以方便地進(jìn)行互換使用。
