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