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