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

用途

DZB-10B系列中间继电器用于直流操作的各种保护和自动控制线路中作为辅助继电器,以增加触点的数量及触点的容量。DZB-11B12B13B为电压启动,电流保持的中间继电器;DZB-14B为电流启动电压保持的中间继电器。DZB-15B为电流或电压动作,电流保持或电压保持的中间继电器。

结构和工作原理

继电器为电磁式动作继电器。采用JK-1型壳体,将DZB-200机芯装入壳体中,具有透明的壳罩,可以清楚观察到继电器的内部结构。外形尺寸及开孔图见附录,内部接线图见图1。当动作电压(或电流)加在线圈两端时,衔铁向闭合位置移动,此时,动合触点闭合,动断触点断开,断开电源时,由于具有电压(或电流)保持绕组磁场的存在,所以衔铁仍然闭合,只有保持绕组断电后,衔铁在接触片的压力作用下返回到原始状态,动合触点断开,动断触点闭合。
