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