一、接地装置宜采用钢材，接地装置的导体截面应符合热稳定和机械强度的要求，但应不小于下表规格。

 

1. Steel shall be used for the grounding device. The conductor section of the grounding device shall meet the requirements of thermal stability and mechanical strength, but not less than the specifications in the table below.

 

 

 

二、接地体顶面埋没深度不应小于0.6米，角钢及钢管接地体应垂直配置。除接地体外，接地体的引出线应作防腐处理；使用镀锌扁钢时，引出线的螺栓连接部分应补刷防腐漆。

 

Two. The depth of the top surface of the grounding body should not be less than 0.6 M. the angle steel and the grounding of the steel tube should be vertically arranged. In addition to the grounding body, the lead-out wire of the grounding body should be treated as anticorrosive; when using galvanized flat steel, the bolt connection of the lead-out wire should be brushed with anticorrosive paint.

 

 

 

三、为减少相邻接地体的屏蔽作用，垂直接地体的间距不应小于其长度的两倍，水平接地体的间距应根据设计规定，不宜小于5米。

 

Three. In order to reduce the shielding effect of adjacent ground body, the distance between the vertical grounding body should not be less than two times of its length, and the distance between the horizontal earthing body should not be less than 5 meters according to the design rules.

 

 

 

四、接地体与建筑物的距离不宜小于1.5m。

 

Four. The distance between the grounding body and the building should not be less than 1.5m.

 

 

 

五、接地线应防止发生机械损伤和化学腐蚀，接地线在穿过墙壁时应通过明孔，穿钢管或其他坚固的保护套。

 

5. The grounding wire shall prevent mechanical damage and chemical corrosion. The grounding wire shall pass through open holes and pierce steel pipes or other strong protective jackets when passing through walls.

 

 

 

六、接地干线至少应在不同的两点与接地网相连接。

 

Six, the grounding main line should be connected to the grounding grid at least two different points.

 

 

 

七、电气装置的每个接地部分应以单独的接地线与接地干线连接，不得在一个接地线中串接几个需要接地部分。

 

7. Each grounding part of the electrical device shall be connected with the grounding trunk line by a separate grounding wire, and several grounding parts that need to be grounded shall not be connected in series in one grounding wire.

 

 

八、敷设完接地体的土沟回填土内不应夹有石块、建筑材料或垃圾等。

 

Eight. The earth gully backfill with the grounding body should not be sandwiched with stone, building materials or garbage.

 

 

 

九、明敷接地线的安装应符合下列要求：

 

Nine. The installation of the grounding wire should meet the following requirements:

 

 

 

（一）便于检查；

 

(1) easy to check;

 

 

 

（二）敷设位置不应妨碍设备的拆卸与检修；

 

(two) laying position shall not hinder the dismantling and maintenance of the equipment.

 

 

 

（三）支持件间的距离在水平直线部分一般为1—1.5米，垂直部分为1.5—2米，转弯部分为0.5米。

 

(3) The distance between the supporting parts is generally 1-1.5 meters in the horizontal straight part, 1.5-2 meters in the vertical part and 0.5 meters in the turning part.

 

 

 

（四）接地线应按水平或垂直敷设，但亦可与建筑物倾斜结构平行，在直线段上不应有高低起伏及弯等情况。

 

(4) Grounding wires shall be laid horizontally or vertically, but they may also be parallel to inclined structures of buildings, and there shall be no ups and downs or bends in straight lines.

 

 

 

（五）接地线跨越建筑物伸缩缝、沉降缝时，应加设补偿器，补偿器可用接地线本身弯成弧状代替。

 

(5) When the grounding wire crosses the expansion joint and settlement joint of a building, a compensator shall be installed, and the compensator may be replaced by the grounding wire itself curved into an arc.
