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