<h1>你知道繼電器綜合實驗裝置的特色有哪些么</h1> <p class="source"><span>日期：2019-11-18</span><span>瀏覽：1200次</span></p> <div> <p>　　你知道<strong><a href="http://www.gfbgyp.cn/SonList-1341637.html " target="_blank">繼電器綜合實驗裝置</a></strong>的特色有哪些么?</p><p>　　1.校驗電流繼電器:</p><p>　　首先，將調壓器置于"0"，控制開關選在"斷"，輸出電流可根據(jù)需要接在交流0-100A(~7.5V)，0-50A(~15V), 0-20A(~110V)，0-(~220V)或直流的輸出端子上。連接好試驗導線，同時，繼電器的常</p><p>　　開或常閉觸點與"被測接點"也連接妥當，然后，合上空氣開關，并將控制開關置于"合"檔，同時，秒表選擇開關放在"常開、常閉"的相反位子，此時蜂鳴器無聲，然后慢慢調節(jié)調壓器，使電流升至蜂鳴器發(fā)聲，表示繼電器已動作，這時可從電壓電流表或外接電流表中讀取動作電流的整定值。</p><p>　　2.校驗電壓繼電器:</p><p>　　首先，將調壓器置于"0"，控制開關選在"斷"，輸出電壓可接在交流電壓0~440V(2.)，0-~220V()， 0-~110V(20A)或直流電壓0--350V(3A)或0--110V(8A)的輸出端子上，接好試驗導線，將繼電器的常開觸點與"被測接點"連接妥當，然后，合上空氣開關，將控制開關置于"合"檔，同時，秒表選擇開關放在"常開、常閉"的相反位子，此時蜂鳴器無聲，然后慢慢調節(jié)調壓器，使電壓升至蜂鳴器發(fā)聲，表示繼電器已動作，這時電壓電流表顯示的數(shù)據(jù)為電壓繼電器的動作電壓，然后，慢慢反向調節(jié)調壓器，使電壓降至蜂鳴器無聲，，這時電壓電流表顯示的數(shù)據(jù)為電壓繼電器的返回電壓。(如試驗所需交流電壓低于10V時，可將試驗導線接在0-50A (~15V)的輸出端子上，并外接的表計)。</p><p>　　3.測量繼電器常開、常閉觸點的動作時間:</p><p>　　首先，根據(jù)被測繼電器的要求，按以上方法選擇好電壓或電流，同時，將繼電器線圈接在相應的輸出端子上，同時將繼電器的常開或常閉接點與"被測接點"連接起來。合上空氣開關，控制開關置于"合"檔，慢慢調節(jié)調壓器至繼電器動作的整定值，再把控制開關轉換至"斷"檔，使繼電器失電。然后:將秒表選擇開關放在與繼電器"常開、常閉"的相同位子，此時蜂鳴器有聲，然后，快速將控制開關朝 "動"的方向旋轉。當繼電器觸點閉合或打開時，秒表停止計數(shù)，秒表指示燈亮，秒表上顯示的值即為常開或常閉觸點動作時間。</p><p>　　4.測量繼電器常開、常閉觸點的返回時間:</p><p>　　首先，根據(jù)被測繼電器的要求，按以上方法選擇好電壓或電流，同時，將繼電器線圈接在相應的輸出端子上，將繼電器的常開或常閉接點與"被測接點"連接起來?？刂崎_關置于"合"檔，慢慢調節(jié)調壓器至繼電器動作的整定值，然后:將秒表選擇開關放在與繼電器"常開、常閉"的相反位子，此時蜂鳴器有聲，然后，快速將控制開關朝
