  1、所有电气设备及其它工艺设备的金属外壳、电缆桥架,包括集装箱、塔、架、钢梯、护栏等,应牢固接地,进出设备管线、长输管线也应接地。

  1. The metal shell and cable tray of all electrical equipment and other process equipment, including containers, towers, racks, steel ladders, guardrails, etc., shall be firmly grounded, and the incoming and outgoing equipment pipelines and long-distance transmission pipelines shall also be grounded.

  2、单栋建筑物的避雷接地尽量采用建筑物的金属构件作为自然接地体,且系统与接地体连接牢固。

  2. For the lightning protection and grounding of a single building, the metal components of the building shall be used as the natural grounding body, and the system shall be firmly connected with the grounding body.

  3、工作、保护、闪电、防静电接地可以共享一组接地系统,电源频率接地电阻不大于4欧姆电阻的实际测量来满足需求,应该添加到接地极,所有non-electrified电气设备金属外壳应未接地。

  3. Work, protection, lightning and anti-static grounding can share a group of grounding system. The actual measurement of power frequency grounding resistance is not greater than 4 ohm resistance to meet the demand. It should be added to the grounding electrode, and the metal shell of all non electrified electrical equipment should not be grounded.

  4、接地设备由笔直接接地柱和地面的水平,和钢笔的直接接地柱应∠50 * 50 * 5 L = 2.5米镀锌角钢,接地柱直接进入地面0.8米,水平地面线选择- 40 * 4扁钢,0.7米深。两个接地极之间的距离为5米。接地极与地线应采用焊接方式连接。接地线重叠12cm。

  4. For the grounding equipment, the level between the pen direct grounding column and the ground, and the pen direct grounding column shall be ∠ 50 * 50 * 5 L = 2.5 m galvanized angle steel, the grounding column shall enter the ground directly for 0.8 m, and the horizontal ground line shall be - 40 * 4 flat steel, 0.7 m deep. The distance between the two earth electrodes is 5 meters. The grounding electrode and ground wire shall be connected by welding. The ground wire overlaps by 12cm.

  5、接地干线与罐壁和建筑物更近点之间的距离不得小于3米

  5. The distance between the main grounding line and the nearest point of the tank wall and the building shall not be less than 3m

  6、从主干线返回的扁钢直线段应进行防腐处理,焊渣应进行清理和清理。

  6. The straight section of flat steel returned from the main line shall be subject to anti-corrosion treatment, and the welding slag shall be cleaned and cleaned.

  7、接地设备的施工和验收见国家标准gb50169-92。

  7. See the national standard gb50169-92 for the construction and acceptance of grounding equipment.

  防雷接地地下镀锌钢管敷设及驱动深度要求有:

  The requirements for laying and driving depth of underground galvanized steel pipe for lightning protection and grounding are as follows:

  根据gb50057-2010第5.4.3条规定,直接接地体的长度和距离应分别为2.5米和5米,可根据当地的限制减少长度和距离。

  According to article 5.4.3 of GB 50057-2010, the length and distance of direct grounding body shall be 2.5m and 5m respectively, which can be reduced according to local restrictions.
