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-10中間繼電器,是上海人民電氣有限公司 http://www.hqbet5695.com 為您提供的關(guān)于DZ-10中間繼電器型號(hào),DZ-10中間繼電器價(jià)格,有關(guān)DZ-10中間繼電器的相關(guān)資料,上海...

    產(chǎn)品介紹

    用途

    本系列中間繼電器用于各種保護(hù)和自動(dòng)控制裝置中,以增加保護(hù)和控制回路的觸點(diǎn)數(shù)量和觸點(diǎn)容量。

    型號(hào)

     

    結(jié)構(gòu)和原理

    本繼電器的接觸系統(tǒng)由幾種帶頂桿的觸點(diǎn)簧片靈活地組裝成多種觸點(diǎn)形式,但根據(jù)傳統(tǒng)需要情況DZ-15 DZ-15Q DZ-16 DZ-16Q DZ-17 DZ-17Q只取2動(dòng)合2動(dòng)斷 3動(dòng)合1動(dòng)斷 4動(dòng)合觸點(diǎn)形式,而DZ-15 DZ-15Q DZ-16 DZ-16Q DZ-17 DZ-17Q只取2動(dòng)合2動(dòng)斷 3動(dòng)合1動(dòng)斷 4動(dòng)中常用的幾種觸點(diǎn)形式。因?yàn)橛|點(diǎn)是裝在導(dǎo)磁體兩側(cè),為了作用力均勻與造型美觀便將兩側(cè)觸點(diǎn)對(duì)稱布置,因此本繼電器觸點(diǎn)組的變化都是成對(duì)的增減。

    雖然在規(guī)定的壽命以內(nèi)繼電器的觸點(diǎn)不必更換,但考慮繼電器的使用時(shí)間實(shí)際是盡可能長的,并且運(yùn)輸、安裝、使用中都可能發(fā)生意外情況使繼電器損壞,在本繼電器中相對(duì)于其它零部件來比,觸點(diǎn)片還是比較容易損壞的,因此將它列為易損件,標(biāo)明圖號(hào),以便使用單位采用。

    根據(jù)繼電保護(hù)用的中間繼電器常與信號(hào)繼電器同時(shí)使用的情況,本繼電器X型產(chǎn)品附有聯(lián)動(dòng)的動(dòng)作信號(hào)指示與復(fù)歸機(jī)構(gòu),并附有一對(duì)帶機(jī)械保持的動(dòng)合觸點(diǎn)以接通遠(yuǎn)方信號(hào)。即完全可以將聯(lián)用的信號(hào)繼電器省掉。這對(duì)提高保護(hù)裝置的可靠性,簡化接線,降低成本是有一定意義的。

    本繼電器采用一個(gè)專用船形支架,其尾部固定底座,中間裝設(shè)繼電器機(jī)構(gòu)。不但拆裝靈活,而且去掉底座、外殼,繼電器仍自成一體,在特殊需要時(shí)可無底無殼供貨。
