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