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