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

CRQ3-100-800系列双电源开关万高型  产品功能解释:?自投自复:当常用电源正常时,控制器发出指令,常用电源控制断路器合,备用电源控制断路器分,自动换关 电器处于(1,0)当常用电源异常时,控制器发出指令,常用电源控制断路器分,备用电源控制断路器分,自动转换 关电器处于(0.1)当常用电源恢复正常时,控制器发出指令,常用电源控制断路器合,备电源控制断路器分,自 动转换关电器又处于(1,01状态。

?自投不自复:当常用电源正常时,控制器发出指令,常用电源控制断器合,备用电源控制断路器分,双电源自动 转换关处于(1,0)当常用电源异常时,控制器发出指令,常用电源控制断路器分,备用电源控制断路器合。

双电源自动转换关处于(0,1)当常用电源恢复正常时,自动转换关电器仍处于(0,1)状态,只有操作复位按钮才能 使常用电源控制断路器合,备用电源控制断路器分,双电源自动切换装置又处于(1,0)状态。

?互为备用:当常用电源正常时,控制器发出指令,常用电源控制断路器合,备用电源控制断路器分,双电源自动 转换关处于(1,0)当常用电源异常时,控制器发出指令,常用电源控制断路器分,备用电源控制断路器合。

   双电源自动切换装置处于(0,1)当常用电源恢复正常时,自动转换装置电器仍处于(0,1)状态,只有备用电源断电,才 能使常用电源控制断路器合,备用电源控制断路器分,双电源自动切换装置又处于(1,0)状态。

?指令(消防I复位(消防指令切非h无论双电源自动切换装置处于何种状态,消防中心发出切非指令,使双电源自动 切换装置常用电源控制断路器和备用电源控制断路器全部分闸,幵关处于(0,0)状态。

?反馈信号:反映双电源自动切换装置两台控制断路器工作状态的信号,一般从控制断路器辅助触点取出信号。 

?电网-电网:双电源自动切换装置电源取自两路电网电源。

?电网-发电机:双电源自动切换装置电源取自电网电源和发电机。

?联络型:联络型双电源自动切换装置有三台塑壳断路器组成。其中,QAQB塑壳断路器分别由两路电源或两段 母线电源供给,QC塑壳断路器在QAQB输出端联络。当其中任意一路电源出现故障,该断路器分闸,QC断路器 重新合闸。双电源自动切换幵关恢复正常工作。

A型控制器

A型控制器置于自动转换装置内部,根据工作电源电压是否正常,决定是否进行电源切换。 

?自动/手动工作方式切换 -自动操作:将自动/手动切换装置置于自动位 -手动操作:将自动/手动切换装置置于手动位

 ?延时时间及工作状态的设定(调整拨码幵关的位置,详见表-)

-转换延时tl: 0,5,15,30s;

-返回延时tl: 0,5,15,30s;
