style="text-indent:25px">金屬電纜橋架類似于電氣設備的外露可導電部分，按電氣相關標準要求應進行接地。但電纜橋架與一般電氣設備的外露可導電部分又不太一樣，它本身長度較長，達到幾十米也很常見。當橋架中間某處發(fā)生相線碰殼接地故障時，由于回路阻抗比較大，若采用過電流兼作接地故障保護，保護電器因回路阻抗大，故障電流小，有可能不動作，所以它的接地與一般電氣設備的接地也有較大差別。GB 50303 - 2015第11. 1. 1條規(guī)定：“梯架、托盤和槽盒全長不大于30 m時，不應少于2處與保護導體可靠連接；全長大于30 m時，每隔20 m ～ 30 m應增加一個連接點，起始端和終點端均應可靠接地?！痹摋l條文說明特別提到：“有的施工設計在金屬梯架、托盤或槽盒內，全線敷設一支銅或鋼制成的保護導體，且與梯架、托盤或槽盒每段有數個電氣連通點，則金屬梯架、托盤或槽盒與保護導體的連接十分可靠?！痹谌菀追e灰和其它需遮蓋的環(huán)境或戶外場所宜加蓋板。</p><div style="width:100%;text-align:
