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