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