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