槽式電纜橋架在接地工作當(dāng)中,該做哪些知識呢?

電纜橋架產(chǎn)品是其電線電纜的搭建工具,它的出現(xiàn)可以有效的對電纜進(jìn)和屏蔽干擾和重腐蝕環(huán)境中電纜的防護(hù)有良好的效果,那么
Cable tray products are the building tools of its wires and cables. Its appearance can effectively shield the cables from interference and corrosion. What knowledge should be done in the grounding work of trough cable tray?
槽式電纜橋架適用于敷設(shè)計(jì)算機(jī)電纜、通信電纜、熱電偶電纜及其它高靈敏系統(tǒng)的控制電纜當(dāng)中,在接地時需要注意的是:橋架系統(tǒng)應(yīng)該具有可靠的電氣連接拼接地;
Trough type cable tray is suitable for laying computer cable, communication cable, thermocouple cable and other control cables of high sensitive system;
當(dāng)橋架系統(tǒng)構(gòu)成接地干線回路時應(yīng)該符合要求:橋架端部之間連接電阻不能大于0.00033歐姆,接地孔應(yīng)該絕緣涂層。在1KV及以下中性點(diǎn)直接地系統(tǒng)當(dāng)中,受電設(shè)備的接地與系統(tǒng)中性線地相連。
When the bridge system forms the grounding trunk circuit, it should meet the requirements: the connection resistance between the ends of the bridge should not be greater than 0.00033 ohm, and the insulation coating should be removed from the grounding hole. In the 1kV and below neutral point direct grounding system, the grounding of the receiving equipment is connected with the neutral line of the system.
裝有處動切斷供電裝桿時,橋架的級長方向金屬橫截面積不能小于規(guī)定值;沿橋架全長另敷設(shè)接地干線時,每段橋架應(yīng)該少有一點(diǎn)與接地干線可靠連接。
The metal cross-sectional area of the cable tray in the direction of grade length shall not be less than the specified value when installing the pole for dynamic cut-off power supply; when another grounding main line is laid along the full length of the cable tray, at least one point of each cable tray shall be reliably connected with the grounding main line.
