Eu sou um crente firme que todo mundo sabe sobre raio rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see raio rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of raio rods. Now let us know with you who invented raio rods, raio rods and the efficacy of raio rod installation standards. 1. Who invented the raio rod. The invention of the raio rod has a good effect on preventing buildings from being struck by raio. Nowadays, there are more and more multi-storey buildings in life, and the use of raio rods is also more common. As everyone knows, many friends do not know who invented the raio rod. Who invented the raio rod? American scientist Franklin invented the contemporary raio rod. Franklin felt that raio was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by raio, 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 raio 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 raio was relatively poor, and Franklin was not injured. The invention of the raio rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about raio strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of raio rod. To put it bluntly, we can understand that the raio rod is a device that prevents raio strikes in buildings. Many multi-storey buildings have raio rods, but many friends do not know the basic principles of raio rods and how to avoid raio strikes in buildings. Traditional raio protection can be divided into anti-shock raio, anti-magnetic induction raio and comprehensive raio protection. The raio protection grounding equipment for shock and raio protection is generally composed of three parts, namely the raio strip, the wire and the grounding body; the raio protection strip is divided into raio rod, raio protection wire and raio protection net. The basic principle of raio protection with the raio rod as the raio strip is: the raio 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 raio 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 raio safety channel, and then pour into the ground to achieve the actual effect of raio protection. In essence, the raio rod is a kind of raio rod, which can cause the surrounding raio, charge and discharge in advance, and transmit the raio current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by raio immediately. 3. Normas de instalação de pára-raios. Lightning rods are used to prevent raio strikes in buildings, so the installation and use of raio rods should be very standardized. Only the installation and use of the raio rod can fully exert the raio protection effect, so the installation of the standard raio rod is very important. 1. A base de concreto deve ser concretada no local de instalação com antecedência, com tamanho de 400 mm × 400 mm × 600 mm (comprimento X largura X altura) e parafusos de ancoragem pré-embutidos ou parafusos de expansão de plástico. 2. Install the raio rod. The raio rod base is fixed on the pre-set prefabricated concrete base. The raio rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The raio 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.
