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

产品介绍
1 用途
  DZB—100系列保持中间继电器 (以下称继电器) 具有自保持绕组,用于直流操作的继电保护回路中,以增加主保护继电器的触点数量和触点容量。
2 结构和动作原理
  继电器为电磁式保持中间继电器。其线圈装在导磁体的铁芯上,它由工作绕组和保持绕组构成:DZB—115型,有一个工作绕组 (电流绕组) 和一个保持绕组 (电压绕组);DZB—127型有一个工作绕组 (电压绕组) 和两个保持绕组 (电流绕组);DZB—138型有一个工作
绕组 (电压绕组)、两个保持绕组 (电流绕组) 和一个阻尼绕组 (端子7—8)。
  继电器的动、静接触系统分别固定于衔铁和磁轭板上。衔铁与磁轭板用锡青铜连接片铰链 (138型用支柱绞链),借拉力弹簧作用,使继电器返回。
    继电器装于胶木底座上,盖以透明塑料外壳。
    继电器可以前面接线也可以后面接线。
其型号和规格见表1。内部接线图见图1。外形和安装尺寸见《附录》。
3 技术数据(见表2)
