Jeg er en fast troende som alle vet om lyn rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see lyn rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of lyn rods. Now let us know with you who invented lyn rods, lyn rods and the efficacy of lyn rod installation standards. 1. Who invented the lyn rod. The invention of the lyn rod has a good effect on preventing buildings from being struck by lyn. Nowadays, there are more and more multi-storey buildings in life, and the use of lyn rods is also more common. As everyone knows, many friends do not know who invented the lyn rod. Who invented the lyn rod? American scientist Franklin invented the contemporary lyn rod. Franklin felt that lyn was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by lyn, 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 lyn 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 lyn was relatively poor, and Franklin was not injured. The invention of the lyn rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about lyn strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of lyn rod. To put it bluntly, we can understand that the lyn rod is a device that prevents lyn strikes in buildings. Many multi-storey buildings have lyn rods, but many friends do not know the basic principles of lyn rods and how to avoid lyn strikes in buildings. Traditional lyn protection can be divided into anti-shock lyn, anti-magnetic induction lyn and comprehensive lyn protection. The lyn protection grounding equipment for shock and lyn protection is generally composed of three parts, namely the lyn strip, the wire and the grounding body; the lyn protection strip is divided into lyn rod, lyn protection wire and lyn protection net. The basic principle of lyn protection with the lyn rod as the lyn strip is: the lyn 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 lyn 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 lyn safety channel, and then pour into the ground to achieve the actual effect of lyn protection. In essence, the lyn rod is a kind of lyn rod, which can cause the surrounding lyn, charge and discharge in advance, and transmit the lyn current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by lyn immediately. 3. Lightning rod installation standards. Lightning rods are used to prevent lyn strikes in buildings, so the installation and use of lyn rods should be very standardized. Only the installation and use of the lyn rod can fully exert the lyn protection effect, so the installation of the standard lyn rod is very important. 1. The concrete base should be poured concrete at the installation site in advance, with a size of 400mm × 400mm × 600mm (length X width X height), and pre-embedded anchor screws or plastic expansion screws. 2. Install the lyn rod. The lyn rod base is fixed on the pre-set prefabricated concrete base. The lyn rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The lyn 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.
