槽式电缆桥架在接地工作当中,该做哪些知识呢?

电缆桥架产品是其电线电缆的搭建工具,它的出现可以有效的对电缆进和屏蔽干扰和重腐蚀环境中电缆的防护有良好的效果,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?
槽式电缆桥架适用于敷设计算机电缆、通信电缆、热电偶电缆及其它高灵敏系统的控制电缆当中,在接地时需要注意的是:桥架系统应该具有可靠的电气连接拼接地;
Trough type cable tray is suitable for laying computer cable, communication cable, thermocouple cable and other control cables of high sensitive system;
当桥架系统构成接地干线回路时应该符合要求:桥架端部之间连接电阻不能大于0.00033欧姆,接地孔应该清除绝缘涂层。在1KV及以下中性点直接地系统当中,受电设备的接地与系统中性线地相连。
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.
装有处动切断供电装杆时,桥架的级长方向金属横截面积不能小于规定值;沿桥架全长另敷设接地干线时,每段桥架应该至少有一点与接地干线可靠连接。
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.
