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