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

          DZ-30B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DZ-30B中間繼電器型號(hào),DZ-30B中間繼電器價(jià)格,有關(guān)DZ-30B中間繼電器的相關(guān)資...

        產(chǎn)品介紹

        用途 

        DZ-30B 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)數(shù)量和觸點(diǎn)容量。

        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DZY-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)。外形尺寸及開孔圖見附圖。當(dāng)電壓加在線圈兩端時(shí),銜鐵向閉合位置運(yùn)動(dòng),此時(shí)動(dòng)合觸點(diǎn)閉合,動(dòng)斷觸點(diǎn)斷開。斷開電源時(shí),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,動(dòng)斷觸點(diǎn)閉合。內(nèi)部接線圖見圖1。
