1. A lightning protection building:
The first type of lightning protection buildings refer to those special buildings that are most sensitive to lightning hazards and need continuous and stable power supply, such as hospitals, nondestructive testing laboratories, computer rooms and communication facilities. These buildings are characterized by the need to maintain a high degree of safety and continuous power supply in lightning weather. Therefore, the first type of lightning protection buildings usually need to take more stringent lightning protection measures, including large-area grounding, lightning protection devices, lightning protection belts, lightning rods and other facilities.
2. The second type of lightning protection buildings:
The second type of lightning protection buildings refer to buildings that are sensitive to lightning hazards, but can accept short-term power outages in areas with low lightning activity frequency, such as ordinary houses, commercial buildings, office buildings, etc. The second type of lightning protection buildings need to be able to protect people's lives and avoid major damage to equipment and building structures when they are struck by lightning. For this reason, the lightning protection measures usually taken include the grounding of the roof of the building, lightning protection belt, lightning rod and so on.
3. The third type of lightning protection buildings:
The third type of lightning protection buildings refer to buildings that are not sensitive to lightning hazards, have low requirements for continuous power supply, and can accept short-term power outages in areas with low lightning activity frequency, such as warehouses, storage rooms, general houses, small commercial buildings, etc. The third type of lightning protection building mainly considers the safety of personnel, and has relatively low protection requirements for equipment and building structures. The usual lightning protection measures include grounding devices, lightning rods, etc. , but don't need too complicated lightning protection facilities.
It should be noted that in different countries and regions, the classification and lightning protection standards of lightning protection buildings may be different, so when lightning protection design is carried out, it is necessary to follow the relevant local laws, regulations and standards to ensure that the lightning protection measures of buildings meet local requirements. In any case, the lightning protection design of buildings should ensure the life safety of personnel and the basic safety of buildings and equipment.
