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