低壓斷路器安裝及使用注意事項

發布日期：2022-04-26 點擊率：313

微型斷路器工作原理

  1. 低壓斷路器應按規定垂直安裝，其上、下連接導線要使用規定截面的導線（或母線），切不可太小了。

  2. 低壓斷路器的脫扣器整定電流及其它特征性參數和選擇參數，一經調好后便不允許隨意更動。使用較長時間后要檢查其彈簧是否生銹卡住，防止影響正確動作。

  3. 檢修后要在不帶電的情況下合、分數次，檢驗動作準確可靠后再投入運行。

應當指出：近幾年來在低壓斷路器的基礎上設計生產的一種新型開關——漏電保護斷路器。它除了可以保護線路找及動力負載的過載和短路，或作為線路的不頻繁轉換機電動機的不頻繁啟動外，還具有當保護區內發生人身觸電或電網漏電時迅速切斷故障電路，起到漏電保護的作用；更多詳情會在日后的學習中提到。
