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 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.

断路器型号及其参数上海人民电气有限公司概述

1、低压断路器型号。DW10系列框架式自动开关;DWX15、DWX15C系列万能式限流断路器;DW17(ME)系列万能式断路器;DZ10系列塑料外壳式自动开关;DZ15系列塑料外壳式断路器;DZX10系列塑料外壳式限流断路器;DZ20系列塑料外壳式断路器;DZ25系列塑料外壳式断路器;

2、高压断路器型号。DW系列高压户外安装多油断路器;SW系列高压户外安装少油断路器;SN系列高压户内安装少油断路器;ZW系列高压户外安装真空断路器;ZN系列高压户内安装真空断路器;LW系列高压户外安装SF6断路器;

3、其实,我们平时说的多少安,指的是断路器的额定电流。额定电流是何意呢?就是指电路中的电流,一旦超过额定电流的数值,断路器就会跳闸。这个额定电流,就是参数中C后面的数字。

4、比如C32,就是指超过32A断路器就会跳闸;C20,就是指超过20A断路器就会跳闸。

5、那C前面那个数字呢,指的是断路器的框架电流。

6、框架电流指的是,该断路器能够承受的最大电流,即如果电路中的电流超过该数值了,断路器就有可能被烧毁。比如DZ47-60C32,指的是断路器的框架电流为60A——在电路中的电流为32A时,断路器会跳闸。但是如果电路中的电流超过了60A,断路器就有烧毁的危险。

7、断路器烧毁,可能会造成不能自动脱扣。因此,框架电流和额定电流相同的断路器,使用起来是有风险的。

8、在选择断路器电流时,一定要结合实际情况,如插座额定功率、插座数量等。不可盲目追求大电流,以免发生电路过载后,断路器不跳闸的情况。

9、极数是断路器选择的另一个大指标,1极又叫做1P。

10、家庭单相电路使用的断路器有1P、1P+N,2P三种。其中,1P断路器是指,只可以断开火线,而且时刻监测火线上的电流,一旦火线上的电流达到额定电流,断路器可以为火线提供保护——跳闸。

11、1P+N断路器是指,可以断开火线和零线,但是电流检测还是只能检测火线,为火线提供保护。

12、2P断路器,可以断开火线和零线,而且同时检测火线和零线上的电流。

13、一般电灯回路,可以选择1P或1P+N断路器。插座回路必须带有漏电保护附件,一般五孔插座选择1P或1P+N的漏电断路器;三孔插座必须选择2P漏电断路器。
