feed cable 【電學】饋電電纜,電源電纜。

feed pipe

The sensor used unbalanced principle of alternating electric field around feed cable to detect the state of electric field of cable core over the ground , thereby got out the result that the feed state of cable in mine had no relation to the current in the cable 該傳感器利用饋電電纜周圍交替電場的不平衡原理檢測電纜芯線對地的電場狀態,從而間接檢測出礦井電纜的饋電狀態與電纜是否有電流無關。
