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

    • 產(chǎn)品描述

      DZ20LE漏電斷路器,是上海人民電氣有限公司 http://www.hqbet5695.com 為您提供的關(guān)于DZ20LE漏電斷路器型號(hào),DZ20LE漏電斷路器價(jià)格,有關(guān)DZ20LE漏電斷路器的相關(guān)資...

    產(chǎn)品介紹
    適用范圍

    a.周圍空氣溫度:上限值不超過(guò)+40℃,下限值不低于-5℃,24h的平均值不超過(guò)+35℃。

    b.安裝地點(diǎn)的海拔不超過(guò)2000m。

    c.安裝地點(diǎn)、大氣相對(duì)濕度在周圍空氣溫度為+40℃時(shí)不超過(guò)50%,在較低溫度下可以有較高的相對(duì)濕度,最溫月的平均最大相對(duì)濕度為90%,同時(shí)該月的月平均最低溫度為+25℃,并考慮到因溫度變化發(fā)生在產(chǎn)品表面上的凝露。

    d.污染等級(jí)3。

    e.安裝類別Ⅲ。

    f.斷路器一般應(yīng)垂直安裝。

    g.漏電斷路器安裝場(chǎng)所的外磁場(chǎng),在任何方向都不應(yīng)超過(guò)地磁場(chǎng)的5倍。

     

    一些常用的型號(hào)有:

    DZ20L-160/3300 DZ20L-160/4300 DZ20L-250/4300 DZ20L-250/4300

    DZ20L-400/3300 DZ20L-400/4300 DZ20L-600/4300 DZ20L-600/4300

    本系列漏電斷路器系電流動(dòng)作型電子式漏電斷路器,主要由零序電流互感器、電子組件板、漏電脫扣器及帶有過(guò)載和短路保護(hù)的斷路器組成。全部零件安裝在一個(gè)塑料外殼中。當(dāng)被保護(hù)線路中有漏電和人身觸電時(shí),只要額定漏電動(dòng)作電流達(dá)到動(dòng)作值,零序電流互感器的二次繞組就輸出一個(gè)信號(hào),經(jīng)電子線路板放大,通過(guò)漏電脫扣器動(dòng)作切斷電源,從而起到漏電和觸電保護(hù)之用。

    四:主要技術(shù)參數(shù)

    a.漏電斷路器的基本規(guī)格及參數(shù)見表2。

    b.配電用反時(shí)限斷開特性見表5。

    c.短路保護(hù)電流整定值為10In,具有±20%的準(zhǔn)確度。

    d.操作循環(huán)數(shù)見表6。

    e.主電路中部導(dǎo)致誤動(dòng)作的過(guò)電流極限值為6In。

    f.在沖擊電壓6000V作用下,漏電斷路器不產(chǎn)生誤動(dòng)作。
