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