韓國(guó)光星KTD-881T,KTD-891T,KTD-862T,參數(shù)產(chǎn)品 圖3c是三相同時(shí)過(guò)載時(shí)的情況,三相雙金屬片同時(shí)向左彎曲,推動(dòng)下導(dǎo)板2向左移動(dòng),通過(guò)杠桿5使常閉觸點(diǎn)立即引計(jì)。圖3d是C相斷線的情況,這時(shí)C相雙金屬片逐漸冷卻降溫,端部向右移動(dòng),推動(dòng)上導(dǎo)板1向右移。而另外兩相雙金屬片溫度上升,端部向左彎曲,推動(dòng)下導(dǎo)板2繼續(xù)向左移動(dòng)。 器和空氣斷路器的配合要根據(jù)空氣斷路器的過(guò)載系數(shù)和短路保護(hù)電流系數(shù)來(lái)決定。器的約定電流應(yīng)小于空氣斷路器的過(guò)載電流,器的接通、斷開電流應(yīng)小于斷路器的短路保護(hù)電流,這樣斷路器才能保護(hù)器。實(shí)際中器在一個(gè)電壓等級(jí)下約定電流和額定工作電流比值在1~1.38之間,而斷路器的反時(shí)限過(guò)載系數(shù)參數(shù)比較多,不同類型斷路器不一樣,所以兩者間配合很難有一個(gè)標(biāo)準(zhǔn),不能形成配合表,需要實(shí)際核算。

對(duì)于帶有聯(lián)動(dòng)架的交流器,按下聯(lián)動(dòng)架,內(nèi)部的常開觸點(diǎn)會(huì)閉合,常閉觸點(diǎn)會(huì)斷開,可以用萬(wàn)用表檢測(cè)這一點(diǎn)是否正常。②檢測(cè)控制線圈的電阻。檢測(cè)控制線圈的電阻如下圖所示,控制線圈的電阻值正常應(yīng)在幾百歐,一般來(lái)說(shuō),交流器功率越大,要求線圈對(duì)觸點(diǎn)的吸合力越大(即要求線圈流過(guò)的電流大),線圈電阻更小。
