Lightning protection and grounding equipmentIt is a device used to protect buildings, equipment, and people from lightning hazards.
Lightning protection and grounding equipment mainly include the following:
Lightning Rod:A lightning rod is a metal rod used to attract lightning and direct it to the ground, usually installed at the highest point of a building or other location that is susceptible to lightning strikes.
Lightning protection belt:A lightning strip is a metal wire used to connect a lightning rod to a grounding device, usually arranged along the exterior wall or roof of a building, forming a closed lightning protection ring.
Grounding device:The grounding device is a kind of equipment used to introduce the current of lightning into the ground, usually composed of a grounding electrode, a grounding wire and a grounding box, etc., the grounding electrode should be buried in the moist soil, the grounding wire should be as short and thick as possible, and the grounding box should be installed in the middle of the grounding wire for inspection and maintenance.
Lightning Protection Shunt:Lightning protection shunt is a kind of equipment used to divert the current of lightning and prevent it from entering the building, usually installed at the inlet of the building, according to its working principle, it can be divided into gas discharge tubes, metal oxide arresters and voltage switches, etc.
Lightning protectorSurge protector SPDLightning protectorIt is a kind of equipment used to protect the electrical equipment inside the building from the overvoltage or overcurrent of lightning, usually installed at the input end of the electrical equipment, and can be divided into power protectors, signal protectors and data protectors according to its protection objects.
Dikai TechnologyThe use and principle of lightning protection grounding equipment is based on the following aspects:
Formation of lightning strikes:Thunder and lightning is a natural phenomenon, when the water vapor in the atmosphere forms clouds under the action of updrafts, the separation of positive and negative charges will occur inside the clouds, and when the accumulation of charges reaches a certain level, a strong electric field will be generated, resulting in electrical discharges inside the clouds or between the clouds and the ground, forming thunder and lightning.
Hazards of lightning:The hazards of lightning are mainly as follows: First, direct hazards, that is, lightning directly hits buildings, equipment or personnel, causing fires, or accidentsThe second is induction hazard, that is, lightning produces a strong electromagnetic field in the surrounding space, which induces voltage or induced current to the electrical equipment or personnel inside the building, causing damage or injury;The third is the surge hazard, that is, the lightning generates surge voltage or surge current on the power line or communication line, causing impact or interference to the electrical equipment or personnel along the line.
The role of lightning protection and grounding equipment:The role of lightning protection and grounding equipment is to minimize the harm of lightning and ensure the safety of buildings, equipment and personnel by means of attraction, diversion, diversion, and protection. Specifically, lightning rods and lightning belts can attract lightning and lead it to the ground, grounding devices can safely release the current of lightning to the ground, lightning protection shunts can divert the current of lightning to different paths, and lightning protection devices can limit the overvoltage or overcurrent of lightning to a certain range, thereby protecting electrical equipment or personnel from damage.
The industry application of lightning protection and grounding equipment is very extensive, and almost all buildings, equipment and personnel need the protection of lightning protection and grounding equipment.
Here are some examples of typical industry applications:
Communication Industry:Equipment and lines in the communications industry are very sensitive, and if they are affected by lightning, they can cause communication interruptions, data loss, or equipment damage. Therefore, the communication industry needs to install lightning rods, lightning protection belts, grounding devices, lightning protection shunts and lightning protection devices to ensure the stability and reliability of communication.
Power Industry:Equipment and lines in the power industry are very important, and once affected by lightning, it can cause power outages, power accidents, or equipment damage. Therefore, the power industry needs to install lightning rods, lightning protection belts, grounding devices, lightning protection shunts and lightning protection devices to ensure the safety of electricity.
Petrochemical industry:Equipment and materials in the petrochemical industry are very dangerous and can cause fires, or people if they are affected by lightning. Therefore, the petrochemical industry needs to install lightning rods, lightning protection belts, grounding devices, lightning protection shunts and lightning protection devices to prevent disasters caused by lightning.
Agricultural industry:Crops and livestock in the agricultural industry are highly prized, and when affected by lightning, they can cause death, injury, or reduced yields. Therefore, the agricultural industry needs to install lightning rods, lightning belts, grounding devices, lightning protection shunts and lightning protectors, etc., to protect the production and development of agriculture.
