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