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

RXSF1型双掉牌型信号继电器

1   用途
用于电力系统二次回路及工业自动化控制回路中,作故障指示及报警之用。

2   特点
2.1 继电器体积小,在最小的安装外壳内装有二个****的信号继电器
2.2 信号牌显示清晰,每一个继电器有三付触点。
2.3 继电器上的铭牌可以脱卸,因此可印上所需的文字。

3   动作原理

RXSFl型双元件信号继电器是在一个最小外壳内装有二个****的信号继电器。该继电器为电磁拍合式结构,由电磁系统,接触系统及信号显示三部分组成。当继电器动作时信号牌靠重力自然掉牌显示,信号为四条横条显示。颜色有红、黄荧光色二种,显示清晰视角宽广。信号消失时,触点自然复回,信号牌有手动复归及自动复归二种,外壳采用引进的Combiflex凸出式模数化插入结构。
4   技术数据
4.1 动作值:电压型≤70%额定电压;电流型为90%额定电流。
4.2 返回值:>2%额定电压或电流。
4.3 动作时间:电压型30ms,电流型2倍额定电流时为15ms
4.4 线圈功耗:电压型<1.5W,电流型<0.2W。

4.6 电流型动作掉牌的最短脉冲时间为50ms。
4.7 触点能力与RXMAl型相同。
4.8 绝缘耐压:50Hz,lmin,2kV。
4.9 冲击电压:5kV。
4.1O 能承受5-15Hz中等震级的地震波冲击
