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