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