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