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