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