Following London 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 staying 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, "yes," 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 the 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.

结构特征

1。HGL负荷隔离开关采用模块化设计,适用于接通与分断电路或电气隔离之用,1000A以上只用作电气隔离。

2。开关采用弹簧蓄能、瞬时释放的加速关合机构及同事接通与断开并联双断点的触头结构,极大的提高了产品的电气性能与机械性能。

3。开关采用玻璃纤维增强不饱和聚脂模塑料及手动操作手柄,具有很高的介电性能、防护能力及可靠的操作安全性。

4.开关具有3极、4极(3极+可通断中性极)

5.开关正面设有标记窗口,只是触头的通断状态,可根据需要提供后面观察窗口,直接观察触头的通断状态,保证开关操作的可靠性和安全性。

6.手柄可直接装在开关上操作(简称柜内操作),也可通过加长轴在配电柜门外操作(简称柜外操作),提供操作方便。

7.可根据需要提供常开常闭辅助触头及安装专用地板与板前板后接线方式,以满足客户的多种需求。

8.在分断位置"0"时,可用两至三把锁锁住手柄,以防止误操作。
