桥架安装在不同场合如何接地
在我们使用桥架的过程中，根据其安装的场合不同，其采用的接地方式也是不一样的，那么您知道分别采用的什么样的接地方法吗？下面我们为您整理相关内容。
In the process of using the cable tray, the grounding methods are different according to the different installation occasions. Do you know what grounding methods are used? Now let's organize the relevant content for you.

桥架可能存在的安装场合以及如何接地的情况有以下三种：
There are three possible installation occasions and grounding methods for cable tray:
1、当允许利用桥架系统构成接地干线回路时，桥架端部之间连接电阻应不大于0.00033欧姆 ，接地孔应绝缘涂层。在1KV及以下中性点直接接地系统中，受电设备的接地与系统中性线接地相连。
1. When the cable tray system is allowed to form the grounding trunk circuit, the connection resistance between cable tray ends shall not be greater than 0.00033 ohms, and the insulation coating shall be removed from the grounding hole. In the neutral point direct grounding system of 1KV and below, the grounding of the receiving equipment is connected with the system neutral line grounding.
2、装有处动切断供电装轩时，桥架的级长方向金属横截面积应不小于规定值。沿桥架全长另敷设接地干线时，每段（包括非直线 段）桥架应少有一点与接地干线可靠连接。
2. When equipped with automatic cut-off power supply device, the metal cross sectional area of the cable tray in the level direction shall not be less than the specified value. When the grounding main line is laid along the full length of the bridge, at least one point of each section (including the non straight line section) of the bridge shall be reliably connected with the grounding main line.

3、对于振动场所，桥架不同的安装场合的接地要点说明：在接地部位的连接处应装置弹簧圈。
3. Key grounding points for vibration places and different installation occasions of bridge: spring coil shall be installed at the connection of grounding parts.
电缆桥架之间可利用连接板作为跨接线，把桥架连成一体。在连接板两端的两只连接螺栓上加镀锌弹簧垫圈，桥架之间用软铜线进行跨接，再将桥架与接地线相连，形成电气通路。桥架整体与接地干线应有不少于两处的连接。接地作业完成后需要检查验收。
Connecting plates can be used as jumpers between cable trays to connect them into a whole. Galvanized spring washers are added to the two connecting bolts at both ends of the connecting plate. Soft copper wires are used for bridging between bridges, and then the bridge is connected with the grounding wire to form an electrical path. There shall be at least two connections between the whole bridge and the grounding trunk. Inspection and acceptance are required after the grounding operation is completed.
