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

          DZB-10B保持中間繼電器,是上海人民電氣有限公司 http://www.mauscontracting.com 為您提供的關(guān)于DZB-10B保持中間繼電器型號(hào),DZB-10B保持中間繼電器價(jià)格,有關(guān)DZB-10...

        產(chǎn)品介紹

        用途

        DZB-10B系列中間繼電器用于直流操作的各種保護(hù)和自動(dòng)控制線路中作為輔助繼電器,以增加觸點(diǎn)的數(shù)量及觸點(diǎn)的容量。DZB-11B,12B,13B為電壓?jiǎn)?dòng),電流保持的中間繼電器;DZB-14B為電流啟動(dòng)電壓保持的中間繼電器。DZB-15B為電流或電壓動(dòng)作,電流保持或電壓保持的中間繼電器。

        結(jié)構(gòu)和工作原理

        繼電器為電磁式動(dòng)作繼電器。采用JK-1型殼體,將DZB-200機(jī)芯裝入殼體中,具有透明的殼罩,可以清楚觀察到繼電器的內(nèi)部結(jié)構(gòu)。外形尺寸及開(kāi)孔圖見(jiàn)附錄,內(nèi)部接線圖見(jiàn)圖1。當(dāng)動(dòng)作電壓(或電流)加在線圈兩端時(shí),銜鐵向閉合位置移動(dòng),此時(shí),動(dòng)合觸點(diǎn)閉合,動(dòng)斷觸點(diǎn)斷開(kāi),斷開(kāi)電源時(shí),由于具有電壓(或電流)保持繞組磁場(chǎng)的存在,所以銜鐵仍然閉合,只有保持繞組斷電后,銜鐵在接觸片的壓力作用下返回到原始狀態(tài),動(dòng)合觸點(diǎn)斷開(kāi),動(dòng)斷觸點(diǎn)閉合。
