講解一下槽式電纜橋架接地要點
槽式電纜橋架接地要點:
Groove type cable tray grounding points:

1、橋架系統(tǒng)應具有可靠的電氣連接并接地(只對金屬橋架)。
1, the bridge system should have reliable electrical connection and grounding (only for metal bridge).
2、當允許利用橋架系統(tǒng)構成接地干線回路時應符合下列要求。橋架端部之間連接電阻應不大于0.00033歐姆,接地孔應絕緣涂層。在1KV及以下中性點直接接地系統(tǒng)中,受電設備的接地與系統(tǒng)中性線接地相連。裝有處動切斷供電裝軒時,橋架的級長方向金屬橫截面積應不小于規(guī)定值。
2, when allowed to use bridge system grounding main circuit, shall meet the following requirements. Connection between the bridge end resistance should be no greater than 0.00033 ohms, grounding insulation coating shall be removed. In the neutral point grounding system directly 1 kv and below, from electrical equipment grounding connected to the neutral grounding system. Move to cut off the power supply is installed with a place porch, prefect direction of bridge metallic cross-sectional area shall be not less than the specified value.
3、沿橋架全長另敷設接地干線時,每段(包括非直線段)橋架應少有一點與接地干線可靠連接。
3, along the bridge span laying grounding line, other (including the straight segment) for each bridge should be at least a little and reliable grounding line connection.
4、對于振動場所,在接地部位的連接處應裝置彈簧圈。
4, for vibration place, in the joint of ground parts should be spring coil.
