商業超市冰柜壓縮機不啟動的維修案例

綠締冷柜 / 2021-08-16 / 閱讀: / 點贊: 給我點贊

  故障分析:斷電后,拆下啟動繼電器和過載保護器,從壓縮機接線柱上測量其電機繞組值,發現啟動繞組短路,需進行剖殼修理。

  故障維修:鋸開超市風幕柜壓縮機外殼,查看定子繞組。發現啟動繞組的槽外部分被燒斷了兩匝線,粘結在一起形成了短路。用鉗子剪斷這兩匝線,出現4個斷頭,加上啟動繞組本身的2個頭,共有6個頭。用萬用表找出各自的頭和尾,并用相同規格超市風幕柜的耐氟漆包線將頭尾連接好,焊接處不得有毛刺,用聚酷薄膜分別將每個接頭包好。用萬用表測量啟動繞組的直流電阻,阻值與正常值一致后,即可將超市風幕柜繞組線圈迸行綁扎。綁扎時要把各接頭分開一些,不與其他導線相碰。
