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

      DZ-30B中間繼電器,是上海人民電氣有限公司 http://www.hqbet5695.com 為您提供的關(guān)于DZ-30B中間繼電器型號,DZ-30B中間繼電器價格,有關(guān)DZ-30B中間繼電器的相關(guān)資...

    產(chǎn)品介紹

    用途 

    DZ-30B 系列中間繼電器用于直流操作的各種保護和自動控制線路中,作為輔助繼電器以增加觸點數(shù)量和觸點容量。

    結(jié)構(gòu)和工作原理

    繼電器為電磁式動作繼電器。采用JK-1型殼體,將DZY-200機芯裝入殼體中,具有透明的殼罩可以清楚觀察到繼電器的內(nèi)部結(jié)構(gòu)。外形尺寸及開孔圖見附圖。當電壓加在線圈兩端時,銜鐵向閉合位置運動,此時動合觸點閉合,動斷觸點斷開。斷開電源時,銜鐵在接觸片的壓力作用下,返回到原始狀態(tài),動合觸點斷開,動斷觸點閉合。內(nèi)部接線圖見圖1。
