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