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

注意事项

4.1  延时越短的继电器越容易整定,实际准确度高,故建议优先选用。特别是采用0.3秒保护时间级差时,应选用延时范围不大于5秒的继电器。

4.2  做延时整定时,应注意两次通电动作之间,要留有一定的间隔时间,以确保整定值的准确度。

4.3  带有电流保持回路的继电器,使用时注意工作电压与自保持电流回路同极性 (电压、电流回路极性见图3端子接线图)。如果极性反,易将电流回路触点损坏。

4.4  继电器在工作过程中,应定期检查它的出口触点,若有烧毁,应检查开关辅助触点是否断开过慢。

4.5  长期工作制的产品,在安装运行和维护中应防止外附电阻及其连接导线接地。

该系列时间继电器(以下简称继电器)作为延时控制元件,用于电力系统继电保护装置及自动化装置中,使被控设备或电路按照预定的延时动作。
主要特点如下:
a.具有较高的延时准确性。可以将阶段式继电保护的级差压缩为0.3s。
b.可靠性强,不存在发卡拒动的问题,并已取得大量的成功运行经验。
c.配置了电流自保持触点,有利于直接接通跳闸回路。
d.通用性强。该继电器采用与DS—110系列时间继电器相同的外壳,并充分考虑了端子接线与上述继电器的对应关系。因此,可以方便地进行互换使用。
