Problems solved by technology

[0008] To sum up, there is no system that includes effective lightning protection equipment that is different from the existing technology, as well as synchronous verification and statistical lightning strikes. There is an urgent need for a lightning protection measure that can qualitatively and quantitatively prove that it can replace or modify the current lightning protection system. standards and provide sufficient and valid evidence

Embodiment 1

[0071] Location: A launch base in North China (because the specific geographical information is involved in the tables and drawings, in order to prevent leakage, the place name, latitude and longitude and other information have been processed), the base is located in a mountainous area.

[0072] Equipment: equivalent ion lightning arresting unit, lightning strike leakage voltage detection unit, lightning counter unit and lightning detection unit, the equivalent ion lightning arresting unit is set on the 30-meter and 92-meter iron towers respectively, and a lightning strike leakage voltage is set for each iron tower As for the detection unit, multiple lightning counter units and a lightning detection unit are installed in the base and surrounding areas. The lightning counter units are installed in open places and on iron towers, and the lightning detection units are installed on 92-meter iron towers.

[0073] In mid-August 2017, there were three consecutive days of severe thunde...

Embodiment 2

[0091] Location: An island in the central part of the Bohai Sea, covering an area of ​​2.72 square kilometers. The island is located in the hinterland of the Bohai Sea. The altitude of the Dengta Mountain on the northwest side is 180 meters. The island has frequent lightning activities during the thunderstorm season every year, and the cumulative probability is much higher than that of the Yantai area to which it belongs. , When the lightning strike is severe, the way of closing the door and going to bed to avoid the lightning strike adopted by the officers, soldiers and common people stationed on the island has formed the norm of lightning protection.

[0092] Install the equivalent ion lightning arresting unit on the base of the top of Dengtashan, install the lightning leakage voltage detection unit at the foot of the mountain, install multiple lightning counter units at the south, north and foot of the mountain, and install the lightning detection unit below the equivalent io...

Embodiment 3

[0096] Location: Liaoning 110 kV high-voltage transmission line network. A section of the line network is located on the side of the Yalu River and on the slope of Fenghuang Mountain. In summer, the southeast wind generated along the river rises along the hillside and affects the local climate, which makes the local area extremely prone to lightning. High-voltage lines in this area are often tripped due to lightning strikes.

[0097] Before March 2017, install an equivalent ion lightning arresting unit on the top of each high-voltage transmission tower in the above-mentioned line section, and install a lightning leakage voltage detection unit at the bottom of each high-voltage transmission tower. A lightning counter unit is installed on the side of the transmission tower, and a lightning detection unit is installed on the top of the highest high-voltage transmission tower. A total of ten equivalent ion lightning arresting units are used.

[0098] The test results proved that d...

Abstract

The invention relates to an equivalent ion lightning prevention unit comprising an upper electrode, a lower electrode and an insulating medium. A lower end of the insulating medium is embedded in theupper end of the lower electrode; an upper end of the insulating medium is embedded into the lower end of the upper electrode; a cavity is kept between the upper end surface the insulating medium andthe top surface inside the upper electrode; and a gap is reserved between the lower end surface of the upper electrode and the upper end surface of the upper electrode. A plurality of lightning receiving rods are arranged on the upper end surface of the upper electrode. According to the invention, the equivalent ion lightning prevention unit is installed at the top of a highest building like a high-rise building, a television tower, a power tower, a wireless telecommunication transmission tower, a tower rack in a tourist attraction, or a chimney, in a protection range; energy collection is carried out by using the equal-height lightning receiving rods arranged at the upper ends; charge neutralization is carried out around the insulating medium and thus the thundercloud energy is consumed at the effective radius around the equipment and thus no downlink discharging channel is formed; and the residual voltage after lightning prevention is lower than or close to 120 volts and is extremelylower than a voltage of lightning discharging on the normal condition, so that safety working of electrical equipment and communication facilities around, inside and outside the building is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of structural innovation of equivalent ion lightning arresting equipment, in particular to an equivalent ion lightning arresting unit and a comprehensive lightning protection system. Background technique [0002] Lightning is a discharge phenomenon between thunderclouds with opposite charges or between charged thunderclouds and the earth. Among all lightning discharge forms, the negative polarity discharge of thunderclouds to the earth or the positive polarity discharge of the earth to thunderclouds has a large current And higher energy, lightning strike protection is most concerned about the current waveform and lightning parameters of each lightning strike discharge, specifically: 1. Peak current: When the lightning current flows through the struck object, it will cause the temperature of the struck object to rise , leading to damage to the object being struck, when the lightning current flows through the ...
