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

              接觸器主要分類

              2013/11/6 9:55:54      點擊:

              接觸器按主觸點連接回路的形式分為:直流接觸器、交流接觸器。

              按操作機構分為:電磁式接觸器、永磁式接觸器。

              永磁交流接觸器是利用磁極的同性相斥、接觸器異性相吸的原理,用永磁驅動機構取代傳統的電磁鐵驅動機構而形成的一種微功耗接觸器。國內成熟的產品型號:CJ20J、NSFC1、NSFC2、NSFC3、NSFC4、NSFC5、NSFC12、NSFC19、CJ40J、NSFMR。

              安裝在接觸器聯動機構上極性固定不變的永磁鐵,與固化在接觸器底座上的可變極性軟磁鐵相互作用,從而達到吸合、保持與釋放的目的。軟磁鐵的可變極性是通過與其固化在一起的電子模塊產生十幾到二十幾毫秒的正反向脈沖電流,而使其產生不同的極性。

              根據現場需要,用控制電子模塊來控制設定的釋放電壓值,也可延遲一段時間再發出反向脈沖電流,以達到低電壓延時釋放或斷電延時釋放的目的,使其控制的電機免受電網晃電而跳停,從而保持生產系統的穩定。

              按驅動方式分為:液壓式接觸器、氣動式接觸器、電磁式接觸器。

              按動作方式分為:直動式接觸器、轉動式接觸器。
