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