在安装电缆桥架的时候,有一项操作步骤是进行接地安装,而这项安装操作一定要正确进行,不然一旦接线错误就会严重影响后期的使用安全。所以下面小编就来给大家讲一讲改桥架接地安装时的一些注意事项吧。
When installing the cable tray, one operation step is to install the grounding, and this installation operation must be carried out correctly, otherwise once the wiring error will seriously affect the later use safety. So let's talk about some precautions when changing the bridge grounding installation.
1、电缆桥架系统应具有可靠的电气连接并接地(只对金属桥架)。
1. The cable tray system shall have reliable electrical connection and grounding (only for metal tray).
2、当允许利用桥架系统构成接地干线回路时应符合下列要求。桥架端部之间连接电阻应不大于0.00033欧姆,接地孔应清除绝缘涂层。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。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。
2. When the bridge system is allowed to form the grounding trunk circuit, the following requirements shall be met. The connection resistance between bridge ends shall not be greater than 0.00033 ohm, and the insulating coating shall be removed from the grounding hole. In the neutral point direct grounding system of 1kV and below, the grounding of power receiving equipment is connected with the neutral line grounding of the system. When a power cut-off device is installed, the metal cross-sectional area in the level direction of the bridge shall not be less than the specified value.
3、沿电缆桥架全长另敷设接地干线时,每段(包括非直线段)桥架应至少有一点与接地干线可靠连接。
3. When another grounding main line is laid along the whole length of the cable tray, at least one point of each section (including non-linear section) of the tray shall be reliably connected with the grounding main line.
4、对于振动场所,在接地部位的连接处应装置弹簧圈。
4. For vibration places, spring coils shall be installed at the connection of grounding parts.
所以大家在进行电缆桥架接地安装的时候,一定要多加注意以上这些内容,并严格按照正确的方法步骤来进行接地操作,从而更好地、更快的完成桥架的接地安装操作。
Therefore, when installing the cable tray grounding, we must pay more attention to the above contents, and carry out the grounding operation in strict accordance with the correct methods and steps, so as to better and faster complete the bridge grounding installation operation.
