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