How to prevent container trailer from lightning strike

The lightning protection of container trailer mainly includes external lightning protection system and internal lightning protection system. The lightning protection of metal roof belongs to the external lightning protection system, which is the lightning protection method of traditional buildings and Franklin's traditional lightning rod or lightning rod combined with lightning protection network.

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

1, lightning arrester function of lightning protection devices inside and outside buildings

The lightning arresters installed in mobile houses can be lightning arresters such as lightning rods, lightning belts or lightning protection nets according to the actual situation. The selected lightning arrester should have specific current and voltage resistance, continuous lightning arrester effect and aesthetic unity between lightning arrester and building.

2. Shunt effect of down lead

The thickness and quantity of down conductor directly affect the shunting effect. If there are many down leads, the lightning current passing through each down lead is very small and the induction range is very small.

The distance between down leads should not be less than that specified in the specification. When the building is very high and the down conductor is very long, an equalizing ring should be added in the middle of the building to reduce the induced voltage drop of the down conductor.

3. Potential balance of all components in the activity room

In order to meet the requirements of lightning protection devices, lightning protection devices should be reliably welded, bound or lapped with beams, plates, columns and foundations, and all kinds of metal equipment and metal pipes should be welded or clamped together at the same time to make the whole mobile house a good equipotential body.
