What is the lightning protection device used for, and what is the lightning protection device compos

Mines are divided into direct strike lightning and induction mines.

Direct lightning strikes are outdoor lightning strikes directly on rooftops or trees. In order to avoid this kind of lightning, the roof should be equipped with a lightning rod.

Induction lightning is to turn the surrounding environment into a strong magnetic field through the strong current of outdoor lightning, so signals, cables, and other signals will be struck by lightning, so this is necessary to add arresters to the user's main incoming line.

In order to better protect the safety of the equipment, you can also use a professional lightning protection socket.

I don't know if it helps you, hehe.

The function of lightning protection device: to prevent or reduce the loss of personal life, cultural relics and property caused by lightning strikes on buildings.

Basically all tall buildings, lighthouses, towering towers, etc., should be lightning protected.

Moreover, for different buildings, different uses, lightning protection device requirements are also different.

It's all typed word by word. You can do it

Lightning protection needs to be designed and installed from three aspects.

1. Internal lightning protection.

1: Power --- install power surge protector (generally need graded protection) 2, signal --- install signal lightning protector.

3. Equipotential connection.

2. Installation according to the actual situation of the building: lightning rod, lightning belt, lightning short needle.

3. Grounding: Both internal and external lightning protection require a good grounding system.

It is also possible to consult a lightning protection company.

The main categories are communication lightning protection, lightning protection above 10kv high voltage of electricity, railway lightning protection, where the roots need to use electricity, lightning protection is generally needed, and buildings also need lightning protection!

To put it simply, lightning protection devices are designed to protect equipment from lightning strikes. Any equipment that may be damaged by a lightning strike needs to be installed with lightning protection.

Lightning protection device refers to a group of electrical equipment and materials set up to prevent lightning strikes, and it is an important safety equipment for electrical equipment and buildings. The composition of lightning protection device mainly includes grounding device, lightning rod, lightning cable, lightning belt, etc.

First, the grounding device. Grounding installation refers to electrical equipment such as copper poles, foundation grounding, and grounding grids, which are used to protect buildings and their equipment from lightning. The function of the grounding device is to connect the equipment or structure to the ground in order to disperse the lightning charge, weaken the electric potential, and transfer the charge of the charged body to the ground.

This avoids the destruction of equipment and the electrocution of personnel.

Second, lightning rods. A lightning rod is an electrical conductive device that is installed at the highest point or protruding part of a building to cause lightning. The lightning rod directs the burst of high current to the ground, so that the electrical appliances and personal safety inside the building are effectively protected.

The lightning rod has a strong ability to cause lightning strikes, but it does not eliminate lightning, it only serves to guide it to a safe range.

Thirdly, lightning cables and lightning belts. Lightning cables are generally installed at the highest point of the building to connect the lightning rod to the grounding device. When the lightning rod is struck by lightning, the lightning cable will direct the lightning into the underground grounding device, protecting the building and surrounding electrical equipment from lightning.

The lightning protection belt is a ribbon conductor that connects the lightning rod and the lightning wire, which is generally installed on the wall to connect the lightning protection system in series, so as to ensure the safety of the entire building.

Lightning protection devices are important safety equipment for buildings and electrical equipment, and the safety of buildings and related equipment is often threatened by lightning. The dust describes several components that will effectively protect buildings and their equipment from lightning. Therefore, the necessity and importance of lightning protection devices are self-evident, and the owners and managers of buildings should pay attention to the installation and maintenance of lightning protection devices to ensure the safety of equipment and personnel.

The external lightning protection device includes a flash receiver (lightning rod, net, belt, wire), down conductor and grounding device. Lightning protection is a systematic project, lightning protection is generally divided into external lightning protection and internal lightning protection. External lightning protection in the conventional sense mainly refers to the protection of direct lightning strikes.

In practical application, the external lightning protection is constituted by the flash receiver, down wire, and perfect grounding system. <

The external lightning protection device includes a flash receiver (lightning rod, net, belt, wire), down conductor and grounding device. Lightning protection is a systematic project, and lightning protection is generally divided into two aspects: external lightning protection and internal lightning protection. External lightning protection in the conventional sense mainly refers to the protection of direct lightning strikes.

In practical application, the external lightning protection is constituted by the flash pin, the down wire, and the perfect grounding system.

The external lightning protection device is composed of a lightning receiver, a down conductor and a grounding device, which is mainly used to protect against direct lightning. Internal lightning protection device: It is composed of equipotential connection system and tremor and barrage, common grounding system, shielding system, reasonable wiring system, surge protector, etc., which is mainly used to reduce and prevent the electromagnetic eggplant effect generated by lightning current in the space to be prevented.

Lightning protection devices refer to the sum of flash connectors, down conductors, grounding devices, surge protective devices (SPDs) and other connecting conductors. It is divided into external lightning protection device and internal lightning protection device.

The grounding device is an important part of the lightning protection shed sensitive device. The grounding device discharges the lightning current to the ground to limit the voltage of the lightning protection device to the ground from being too high.

In addition to the independent lightning rod, the lightning protection and grounding device can be shared with other grounding devices under the premise that the grounding resistance meets the requirements.

The lightning protection device consists of an external lightning protection device and an internal lightning protection device. The external lightning protection device is mainly composed of three parts: a flash receiver, a down conductor and a grounding device. The internal lightning protection device is composed of equipotential connection, common grounding device, shielding, reasonable wiring, surge protector, etc.

The grounding device refers to the group of grounding electrodes buried in the ground jujube excavation - below the meter, which is the dispersed electrode that guides the lightning into the ground. If it is artificially set up to be specially entered, it is called an artificial grounding body.

The lightning receiver refers to the conductor that receives lightning, protruding from the building, so that the lightning can be introduced into the earth through it without being introduced through other parts of the building and play a protective role.

The down conductor refers to the conductor that is introduced into the ground by the lightning guide of the lightning receiver to form the path. Main form: There is a lightning protection down wire composed of round steel, flat steel, bare wire, etc. on the surface of the building.

Which three components of the lightning protection device are introduced as follows:

1.Lightning rod: A metal object designed specifically to receive lightning.

The metal rod connected to the lightning is called the lightning arrester, the metal wire connected to the lightning is called the lightning protection wire or overhead ground wire, and the metal strip and metal mesh connected to the lightning are called the lightning protection belt or lightning protection net. All flash receivers must be connected to the grounding device by means of a drain wire. Lightning rods, wires, nets, and belts are all lightning arresters.

2.Down Lead: A metal conductor that directs lightning current from the lightning receiver to the grounding device. The down conductor of the lightning protection device should meet the requirements of mechanical strength, corrosion resistance and thermal stability.

3.Grounding device: It is an important part of lightning protection device.

The grounding device releases lightning current to the ground to limit the voltage of the lightning protection device to the ground from being too high. In addition to the independent lightning rod, the lightning protection grounding device can be shared with other grounding devices under the premise that the grounding resistance meets the requirements.

The lightning protection device is the sum of the flash receiver, down conductor, grounding device, overvoltage protector and other connecting conductors. A lightning receiver is a metal body that is directly struck by lightning.

A down conductor is a metal conductor that connects a flash connector to a grounding device. The grounding device is the sum of the grounding body and the grounding wire, the grounding body is buried in the soil or the concrete foundation as a conductor to make the current flow to the earth, and the grounding wire refers to the conductor connecting the down wire and the grounding body. Usually, the lightning protection device used to protect the building from direct lightning strikes consists of a lightning receiver, a down conductor and a grounding device.
