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

产品介绍
产品简述
RD-ZM型智能低压电容器是最新一代以低压无功补偿电容器为主体,通过微电子软硬件技术、电气制造技术等高新技术手段研发的无功补偿装置。替代常规以电容器、复合开关(或交流接触器)、熔断器配以导线安装而成的低压无功补偿装置在应用、结构方面存在的先天不足而精心研制开发的最新科技成果。
本产品以智能化技术,实现低压无功补偿功能,并使其能够可靠工作、使用方便。集零投切、保护、测量等系列功能,是低压无功补偿技术的重大突破。本产品改变了现阶段无功补偿设备结构模式,具有性能佳、使用方便、性价比高等诸多特点,可以适用于各种无功补偿场合。 基本工作原理是智能模块控制电容器的投切。使智能电容器在接通和断开的瞬间具有过零投切的优点,而在正常接通期间又具有磁保持继电器无功耗的优点。 
智能电容器内置投切开关模块。投切开关模块由晶闸管、磁保持继电器、过零触发导通电路和晶闸管保护电路构成,实现电容器“零投切”,保障投切过程无涌流冲击,无操作过电压触点不烧结;能耗小;无谐波注入、而且具有缺相保护;元件故障保护;运行指示等功能。产品广泛应用于低压感性负载的电力系统。如城市电网、农村电网、民用建筑、厂矿企业、石油化工、电气化铁路及轨道交通等领域的低压配电网络无功补偿,提高功率因数,降低线路耗损,稳定电网电压,保证供电质量,节能降耗增效效果显著。
