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