In the usual rainy days, there will be thunder and lightning, especially the thunder is especially loud. Therefore, some people are more concerned about this aspect, and they will install lightning rods at home. Therefore, even if there is thunder, there is no need to worry about the house at home. Therefore, everyone If you want to know how deep the lightning rod is installed, in addition, take a look at the detailed introduction of the lightning rod.
How deep should the lightning rod be installed?
The vertical grounding interval should not be less than 3 to 5 times its length. The horizontal grounding interval shall meet the design requirements. When there is no design plan requirement, it shall not be lower than 5m. Except for the annular grounding, the grounding site should be 3m away from the building. It should also be more than 3m from the entrance and exit of the building or the pedestrian crossing. If it is less than 3m, use clamps or lay a 50-90mm thick bitumen layer on the grounding equipment, and the total width should exceed the grounding equipment by 2m.
1. The lightning rod of machinery and equipment is a reasonable way to prevent lightning strikes. A metal rod is erected at the top of the house, a copper core wire of sufficient thickness is connected below the rod, and a metal material plate is connected below the copper wire, buried in the deepest wet and cold area of ​​the ground. The top of the metal rod must be sharp or branched into multiple sharps. With this type of equipment, when there is an electrified cloud in the air.
2. Because of the tip discharge, the tip of the lightning rod concentrates different charges, causing the tip discharge, which is neutralized with the electricity in the cloud to prevent strong lightning. This is also a level where lightning rods can protect against lightning. But this kind of practical effect is very slow. If the accumulation of electricity in the cloud is rapid, or a cloud with a lot of electric charge suddenly flies over, sometimes the above methods do not help, so strong discharge and lightning will occur.
Introduce lightning rods in detail.
1. Lightning rod, also known as lightning rod. Shiny poles to maintain house construction. Tall and big trees and other lightning protection devices. Install a shiny RF connector on top of the protected object to connect to a leaky mesh buried in the ground. The size of the lightning rod must meet the GB specification. The relative height of the lightning rod required by each type of lightning protection is different.
2. When the thundercloud discharge is close to the floor, it will distort the electrostatic field of the road surface. At the top of the lightning rod, there is a centralized indoor space where part of the electrostatic field is generated, which jeopardizes the development prospects of the lightning discharge. Was struck by lightning.
3. Because of the structural characteristics and functions of the lightning rod, attention should be paid to maintaining the excellent electrical conductivity of the lightning rod. In the event of a poor connection or rupture, a portion of the upper edge of the fracture becomes the protective conductivity system software.
4. When there is electric charge in the cloud, a part of the upper magnetic induction and the electric charge in the cloud are separated, and the lower magnetic induction is the same electric charge as the electric in the cloud. If the upper end and cloud power have the discharge function, the strong discharge current can only release a lot of heat according to the building, which will cause lightning strikes. This is not only impossible to prevent lightning, but also causes lightning disasters. In order to avoid casualties, it is best to erect two lightning rods in multi-storey buildings. In addition, each lightning rod only maintains a certain total building area. For large and medium-sized engineering buildings, two lightning rods must also be erected.
According to the detailed explanation of this article, everyone has already understood how deep the lightning rod installation is. The content of the article is written in depth. If the installation specification is shallow, it will immediately harm the actual effect. Therefore, it should be noted that everyone also understands that the detailed explanation of the lightning rod is What, these items are used to maintain engineering buildings. Therefore, it is especially effective for installation of poles and houses. You can go to the sales market to buy and buy basic products to ensure the actual effect in the middle and later stages.
