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

松川功率继电器负载的四种类型介绍

2013/12/4 11:21:00点击:
功率继电器也是继电器其中的一种,功率继电器是一种在输入量满足某些规定的条件时,能在一个或多个电器输出电路中产生跃变的一种器件。可用于中性点直接接地系统,作为零序电流保护的方向元件。

  功率继电器的负载主要可分为以下四种类型:

  1、中功率继电器

  当触点开路电压为直流28V时,触点额定负载电流(阻性)为2A;5A的继电器。

  2、大功率继电器

  当触点开路电压为直流28V时,触点额定负载电流(阻性)为10A;15A;20A;25A;40A……的继电器。

  3、微功率继电器

  当触点开路电压为直流28V时,触点额定负载电流(阻性)为0.1A;0.2A的继电器。

  4、弱功率继电器

  当触点开路电压为直流28V时,触点额定负载电流(阻性)为0.5A;1A的继电器。
