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