The utility model has the advantages of strong environmental adaptability, fast installation speed, long service life, thermal insulation, etc. It is widely used in road, railway, construction and other field operations of temporary buildings. With the continuous improvement of people's safety awareness, the lightning protection problem of container mobile house in steel structure engineering has become the main concern of customers, so it is necessary to install lightning protection device. So, how to do the lightning protection work of container activity room well? Below with container room small make up to understand together!

怎样做好防雷工作?

How to do lightning protection work well?

屋防雷，主要包括外部防雷系统、和内部防雷系统，金属屋面防雷属于外部防雷系统，传统建筑的防雷模式，是富兰克林的传统避雷针、或避雷针结合防雷网络。

The metal roof lightning protection belongs to the external lightning protection system. The lightning protection mode of traditional buildings is Franklin's traditional lightning rod, or lightning rod combined lightning protection network.

然而，彩钢屋面板的金属板相对较薄，因此不可能安装又高又重的传统避雷针，因此，在设计金属屋面建筑时，应根据防雷设计的五个要素，考虑如何防止屋面雷击。

However, the metal plate of color steel roof panel is relatively thin, so it is impossible to install high and heavy traditional lightning rod. Therefore, in the design of metal roof building, we should consider how to prevent roof lightning according to the five elements of lightning protection design.

1、建筑物内外防雷装置的接闪器功能

1. Lightning arrester function of lightning protection devices inside and outside buildings

安装在活动房屋内的接闪器，可根据实际情况采用避雷针、避雷带或防雷网等接闪器，所选接闪器应具有特定的耐电流和耐压性、连续接闪器效果，以及接闪器与建筑物之间的美观统一性。

The lightning arrester installed in the movable house can use lightning rod, lightning strip or lightning protection net according to the actual situation. The selected lightning arrester should have specific current resistance and voltage resistance, continuous lightning arrester effect, and aesthetic unity between the lightning arrester and the building.

2、下行导线的分流效果

2. Shunting effect of downward conductor

下行导线的厚度和数量直接影响分流效果，如果有许多引下线，通过每个引下线的雷电电流很小，感应范围也很小。

The thickness and number of down conductors directly affect the shunt effect. If there are many down conductors, the lightning current passing through each down conductor is very small, and the induction range is also very small.

引下线之间的距离，不应小于规范中的规定，当建筑物很高且引下线很长时，应在建筑物中间增加一个均压环，以降低引下线的电感压降。

The distance between down conductors shall not be less than that specified in the specification. When the building is very high and the down conductor is very long, a grading ring shall be added in the middle of the building to reduce the inductive voltage drop of down conductors.

3、活动室内各部分电位平衡

3. Potential balance of each part in activity room

为满足防雷装置的要求，防雷装置应与梁、板、柱、基础可靠焊接、绑扎或搭接，各种金属设备和金属管道应同时焊接或夹紧在一起，这使得整个活动房屋成为一个良好的等电位体。

In order to meet the requirements of the lightning protection device, the lightning protection device should be reliably welded, bound or lapped with the beam, plate, column and foundation, and all kinds of metal equipment and metal pipes should be welded or clamped together at the same time, which makes the whole movable house a good equipotential body.
              

4、接地效果

4. Grounding effect

良好的接地效果，是防雷成功的重要保证之一，集装箱活动房防雷接地设置，应符合设计和规范要求，接地电阻测试合格。

Good grounding effect is one of the important guarantees for the success of lightning protection. The lightning protection grounding setting of container mobile room should meet the design and specification requirements, and the grounding resistance test should be qualified.

采用独立接地方式时，钻深埋接地极(约4~12m)效果为好，深孔接地极可以轻松到达地下水位，降低接地极的用钢量。

When the independent grounding mode is adopted, the effect of drilling deep buried grounding electrode (about 4 ~ 12m) is better. The deep hole grounding electrode can easily reach the groundwater level and reduce the steel consumption of grounding electrode.

5、有效走线

5. Effective routing

在集装箱活动房的防雷设计中，务必考虑到防雷系统与这种管道的关联，为了确保在防雷设施接闪时这种管道没受危害，应当将这种电缆线穿于金属软管内，以保持靠谱的屏蔽掉。

In the lightning protection design of container mobile house, the connection between the lightning protection system and the pipeline must be considered. In order to ensure that the pipeline is not harmed when lightning protection facilities are connected, the cable should be put through the metal hose to keep reliable shielding.

然后把这种路线的主干线，竖直一部分设定在高层住宅房屋建筑的管理中 心位置，且防止挨近作为引退出的柱筋，以尽可能变小被磁感应的范畴。

Then, the vertical part of the main line of this route is set at the management center of high-rise residential buildings, and it is prevented from getting close to the column bar as the exit, so as to reduce the area of magnetic induction as much as possible.
