配電箱、配電柜的二次配線工藝質量通病

發布日期:2022-04-26 點擊率:197

 1、箱內配線不整齊,線頭裸露,配線不留余量。

  2、接線端子與導線截面不匹配。

  3、端子接線數量多于2根。

  4、配線分色不符合規范要求。
  5、箱門和箱體之間連接的可移動導線的兩端未用卡子固定。
  6、個別箱體內工作零線、保護地線未接入匯流排。
  7、箱內標認器件無名稱及編號,接線端子無編號:電纜無標志,無回路圖(線路圖)。
  8、線頭彎曲方向應與擰緊螺釘一致,導線與螺釘之間須使用墊圈(片)。
  9、插線式接線端子,不同界面的兩根導線不得接在同一端子上。對于螺      栓連接端子,當接兩根導線時,中間應加平墊片。導線端部剝切長度為插接端子的1/2,不應將導線絕緣層插入,以免造成接觸不良。也不應插入過少,一致掉落。每個接線端子的一端,接線不得超過2根。
  10、二次回路接地應設專用螺栓。
