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