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