由于破碎系統存在斷續性，再加上有些崗位工的責任心不強，造成破碎機械空(kong)運轉時間較長，電力(li)浪費。為(wei)此(ci)本人在(zai)石灰石二破(po)自行設計了(le)一(yi)種簡單實用的空(kong)載(zai)自停(ting)節(jie)電裝置。

 當(dang)石(shi)灰石(shi)二(er)破(po)(po)(po)帶(dai)(dai)(dai)負(fu)荷動轉時(shi)(shi)(shi)(shi)(shi)(shi)（我廠為180～210A），電(dian)流繼(ji)電(dian)器(qi)KA1和KA2常(chang)閉(bi)(bi)觸點(dian)(dian)打開，節電(dian)裝置(zhi)不工(gong)作。當(dang)無負(fu)荷空(kong)運轉時(shi)(shi)(shi)(shi)(shi)(shi)（我廠為75～100A），KA1、KA2常(chang)閉(bi)(bi)觸點(dian)(dian)之一(yi)(yi)(yi)或者兩個釋放閉(bi)(bi)合(he)，時(shi)(shi)(shi)(shi)(shi)(shi)間繼(ji)電(dian)器(qi)KT1線圈得(de)電(dian)開始延時(shi)(shi)(shi)(shi)(shi)(shi)（破(po)(po)(po)碎機(ji)(ji)(ji)主電(dian)路(lu)圖未畫出，KM為二(er)破(po)(po)(po)電(dian)機(ji)(ji)(ji)主接觸器(qi)常(chang)開輔助(zhu)觸點(dian)(dian)，此時(shi)(shi)(shi)(shi)(shi)(shi)為閉(bi)(bi)合(he)），KT1的延時(shi)(shi)(shi)(shi)(shi)(shi)范圍為0～600s。待延時(shi)(shi)(shi)(shi)(shi)(shi)到，其延時(shi)(shi)(shi)(shi)(shi)(shi)觸點(dian)(dian)閉(bi)(bi)合(he)，中(zhong)間繼(ji)電(dian)器(qi)K得(de)電(dian)吸合(he)并自鎖，且串接在(zai)提升機(ji)(ji)(ji)和石(shi)灰石(shi)二(er)破(po)(po)(po)接觸器(qi)回路(lu)的常(chang)閉(bi)(bi)觸點(dian)(dian)斷開將其停(ting)機(ji)(ji)(ji)。石(shi)灰石(shi)一(yi)(yi)(yi)破(po)(po)(po)和皮帶(dai)(dai)(dai)機(ji)(ji)(ji)因聯鎖停(ting)機(ji)(ji)(ji)。同時(shi)(shi)(shi)(shi)(shi)(shi)，K的另(ling)一(yi)(yi)(yi)觸點(dian)(dian)使KT1失電(dian)復(fu)原，另(ling)一(yi)(yi)(yi)常(chang)開觸點(dian)(dian)使時(shi)(shi)(shi)(shi)(shi)(shi)間繼(ji)電(dian)器(qi)KT2得(de)電(dian)延時(shi)(shi)(shi)(shi)(shi)(shi)，其延時(shi)(shi)(shi)(shi)(shi)(shi)范圍為0～1800s。在(zai)其延時(shi)(shi)(shi)(shi)(shi)(shi)范圍內(nei)二(er)破(po)(po)(po)不能再開機(ji)(ji)(ji)。延時(shi)(shi)(shi)(shi)(shi)(shi)時(shi)(shi)(shi)(shi)(shi)(shi)間到，K失電(dian)復(fu)原，二(er)破(po)(po)(po)才能再開機(ji)(ji)(ji)。KT1延時(shi)(shi)(shi)(shi)(shi)(shi)的作用是短時(shi)(shi)(shi)(shi)(shi)(shi)空(kong)載(zai)不停(ting)機(ji)(ji)(ji)，在(zai)其延時(shi)(shi)(shi)(shi)(shi)(shi)范圍內(nei)應盡快使之轉入帶(dai)(dai)(dai)負(fu)荷動轉，才能不停(ting)機(ji)(ji)(ji)。更多詳情請咨詢：0371-64373366
