In a thunderstorm, when charged clouds appear over tall buildings, lift-type lightning rods and high-rise buildings are induced with a lot of charge. As the lift-type lightning arrester needles are pointed, electrostatic induction always leads to the accumulation of most charges at the conductor tip. In this way, lift-type lightning rods gather most of the charge. The lightning rod forms a capacitor with these charged cloud layers. Since it is sharper, that is, the capacitor's bipolar plates face a small area, the capacitance is small, which means that it can hold a small amount of charge. And it gathers most of the charge, so when there is more charge on the cloud, the air between the lifting lightning rod and the cloud can easily break down and become a conductor. In this way, the charged cloud layer forms a path with the lightning rod and the lightning rod is grounded. The lifting type lightning rod can introduce the charge on the cloud layer into the earth so that it does not constitute a danger to high-rise buildings and ensure its safety.
Conventional lightning protection can be divided into direct lightning protection, inductive lightning protection and comprehensive lightning protection. The lightning protection device for direct lightning protection is generally composed of three parts, ie, a lightning arrester, a down conductor, and a grounding body. The lightning receptor is divided into a lightning rod, a lightning conductor, a lightning conductor, and a lightning protection net. The principle of lightning protection using a lifting type lightning rod as a lightning receptor is that the lightning rod is connected to the ground through a wire and forms an equipotential difference with the ground. Using its own height, the electric field of the thundercloud that increases the electric field intensity to a limit value is distorted and ionization begins. Downstream pilot discharge; lift-type lightning rod under the action of a strong electric field to produce tip discharge, the formation of upward pilot discharge; the two meet to form a lightning circuit, followed by diarrhea into the earth, to achieve lightning protection effect. In fact, the lightning rod is a lightning lead, which can lead the surrounding lightning and discharge it in advance. The lightning current is transmitted to the ground through its own grounding conductor to avoid direct lightning strikes on the object of protection.
Lifting lightning rods are widely used in *,*, fire protection, construction, field construction, large-scale cultural and sports activities, disaster protection and other emergency lightning protection and lightning protection for certain specific targets.
The characteristics of mobile lifting lightning rod products, mobile lifting lightning rod with direct flash lightning, the lightning current into the earth, played a direct lightning protection. The use of high-strength aluminum-magnesium alloy profiles, strong corrosion resistance; cylinder wall using high-pressure wear-resistant porcelain treatment process sealing joint. Has a strong anti-rotation function. With self-installation function, easy to move and transport. The maintenance of the tip equipment can be detected and allowed to work properly. Strong wind resistance, can resist wind force of 60m/s. Lightning protection radius is calculated based on the rolling ball method. Highly anti-corrosion, waterproof and dustproof structure features long service life. The lifting mode can be manual or electric, or it can be manually or electrically integrated. Mechatronics control the lightning rod lift, limit, lock, seal. Can be controlled by the electric cabinet or handle button. Can be used with early discharge lightning rod or optimized lightning rod (if matched with lightning rod discharge in advance, lightning protection radius in accordance with relevant national regulations).

Lifting lightning rod installation use
Lifting lightning rod installation instructions were compiled by technical personnel of Zhengzhou Leidi Electronic Engineering Co., Ltd. The lifting type lightning rod is designed as a lifting structure, which can solve the problem that high-altitude aviation flash obstruction lights cannot be maintained or replaced in high altitude, and can ensure the safety and reliability of the lightning contact at the lifting contact surface. The aviation and aviation lights and the lightning rod are integrated into one. Avoid lightning strikes and damage aviation obstruction lights. As all the power cords, electrical appliances and lifting devices are installed inside the lightning rod casing, the lifting device can be protected from damage, the lifting rod of the lightning rod, the lightning rod lifter, the lightning rod lifter, the lifting platform of the lightning rod, and the lightning rod lifting bracket can work stably for a long time and have Easy to install, easy to maintain and replace, beautiful appearance.
