Je suis un croyant ferme que tout le monde connaît foudre rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see foudre rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of foudre rods. Now let us know with you who invented foudre rods, foudre rods and the efficacy of foudre rod installation standards. 1. Who invented the foudre rod. The invention of the foudre rod has a good effect on preventing buildings from being struck by foudre. Nowadays, there are more and more multi-storey buildings in life, and the use of foudre rods is also more common. As everyone knows, many friends do not know who invented the foudre rod. Who invented the foudre rod? American scientist Franklin invented the contemporary foudre rod. Franklin felt that foudre was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by foudre, he placed a paper kite tied with a long wire into a cumulonimbus cloud and placed it on the end of the wire. A bunch of silver keys. When the foudre struck, Franklin's hand came close to the key, and a string of spark discharges erupted from the key. There is a real discomfort in the hand. Fortunately, the foudre was relatively poor, and Franklin was not injured. The invention of the foudre rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about foudre strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of foudre rod. To put it bluntly, we can understand that the foudre rod is a device that prevents foudre strikes in buildings. Many multi-storey buildings have foudre rods, but many friends do not know the basic principles of foudre rods and how to avoid foudre strikes in buildings. Traditional foudre protection can be divided into anti-shock foudre, anti-magnetic induction foudre and comprehensive foudre protection. The foudre protection grounding equipment for shock and foudre protection is generally composed of three parts, namely the foudre strip, the wire and the grounding body; the foudre protection strip is divided into foudre rod, foudre protection wire and foudre protection net. The basic principle of foudre protection with the foudre rod as the foudre strip is: the foudre rod is connected to the ground according to the transmission line, and has an equal phase difference with the floor, making full use of the relative height to increase the magnetic field strength to the specified value. correctly guide the charge and discharge. The foudre rod causes electrostatic induction under the action of a strong electrostatic field, leading to upward charging and discharging; the two move forward to generate a foudre safety channel, and then pour into the ground to achieve the actual effect of foudre protection. In essence, the foudre rod is a kind of foudre rod, which can cause the surrounding foudre, charge and discharge in advance, and transmit the foudre current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by foudre immediately. 3. Normes d'installation des paratonnerres. Lightning rods are used to prevent foudre strikes in buildings, so the installation and use of foudre rods should be very standardized. Only the installation and use of the foudre rod can fully exert the foudre protection effect, so the installation of the standard foudre rod is very important. 1. La base en béton doit être coulée à l'avance sur le site d'installation, avec une taille de 400 mm × 400 mm × 600 mm (longueur X largeur X hauteur), et des vis d'ancrage pré-intégrées ou des vis d'expansion en plastique. 2. Install the foudre rod. The foudre rod base is fixed on the pre-set prefabricated concrete base. The foudre rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The foudre rod wire connector must be reliably connected with the power grounding wire, the wire connector is light green, and the cross-section BVR25mm2 or more copper core wire.
