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

松川继电器行业技术特点

2016/8/4 9:33:09点击:

松川继电器种类非常多,每种继电器的特点都不相同,以下小编简单介绍了几种继电器的特点:

固态继电器

1.高寿命,高可靠:固态继电器没有机械零部件,有固体器件完成触点功能,由于没有运动的零部件,因此能在高冲击,振动的环境下工作,由于组成固态继电器的元器件的固有特性,决定了固态继电器的寿命长,可靠性高。

2.灵敏度高,控制功率小,电磁兼容性好:固态继电器的输入电压范围较宽,驱动功率低,可与大多数逻辑集成电路兼容不需加缓冲器或驱动器。

3.快速转换:固态继电器因为采用固体器件,所以切换速度可从几毫秒至几微妙。

4.电磁干扰小:固态继电器没有输入“线圈”,没有触点燃弧和回跳,因而减少了电磁干扰。大多数交流输出固态继电器是一个零电压开关,在零电压处导通,零电流处关断,减少了电流波形的突然中断,从而减少了开关瞬态效应。

真空继电器

1.真空继电器是将触点置于抽成高真空的玻璃壳或陶瓷壳内,以真空作为灭弧和绝缘介质的继电器。

2.真空具有理想的绝缘性能,在理想状态下可能达到80000V/mm的介电常数,真空中由于没有氧气,所以在使用过程中不会氧化,这样,真空继电器在使用过程中就具有较小而稳定的接触电阻。

3.真空具有良好的灭弧性能。真空中的电弧很容易扩散,不易造成触点的磨损,所以真空继电器具有寿命长的特点,能够带负载开关。综合而言,真空继电器具有耐击穿电压高、熄弧快、开断电流大、体积小、重量轻、寿命长的特点。广泛应用于心脏起搏器、核磁共振成像、高频天线耦合装置、雷达、电容器放电等弱电控制强电的领域中。

4.抗电强度高,额定承载电流和转换电流大,触点接触电阻小,工作稳定,噪声低,极间分布电容和电感小,触点开距小,励磺功率低,开断速度快,触点密封,不受周围环境的气压、水分、沙尘或爆炸气体的影响,适应于恶劣环境中工作。

中间继电器

松川继电器采用线圈电压较低的多个优质密封小型继电器组合而成,防潮、防尘、不断线,可靠性高,克服了电磁型中间继电器导线过细易断线的缺点;功耗小,温升低,不需外附大功率电阻,可任意安装及接线方便;继电器触点容量大,工作寿命长;继电器动作后有发光管指示,便于现场观察;延时只需用面板上的拨码开关整定,延时精度高,延时范围可在0.02-5.00S任意整定。

光继电器

寿命为半永久性、微小电流驱动信号、高阻抗绝缘耐压、超小型、光传输、无接点。
