描述

具有“防跳”回路的斷路器，應(yīng)作“防跳”回路檢查。首先在斷路器合閘后，取下合閘回路熔斷器，在控制盤上將控制開關(guān)轉(zhuǎn)至“合閘”位置不返回；用保護(hù)回路觸點(diǎn)使斷路器跳閘。如回路正確，則斷路器跳閘后，合閘接觸器應(yīng)不再動(dòng)作。然后，恢復(fù)控制開關(guān)至“跳閘”位置，合上合閘回路熔斷器，用短接線接通保護(hù)出口繼電器觸點(diǎn)，在控制盤上將控制開關(guān)轉(zhuǎn)至“合閘”位置，斷路器合閘后，應(yīng)立即跳開，而不繼續(xù)再合。

對(duì)具有備用電源自動(dòng)投入、自動(dòng)重合閘、自動(dòng)準(zhǔn)同期、電動(dòng)機(jī)聯(lián)鎖等控制回路的檢查與通電試驗(yàn)，應(yīng)根據(jù)實(shí)際的一次系統(tǒng)和二次回路的接線，先短接或斷開有關(guān)端子進(jìn)行模擬試驗(yàn)，然后做正式通電整組傳動(dòng)試驗(yàn)，并寫出詳細(xì)、具體的試驗(yàn)方案。
