Embodiment 1

[0058] Location: A launch base in North China (because the table and attached drawings involve specific geographical information, in order to prevent leaks, the place name, latitude and longitude and other information have been processed), the base is located in a mountainous area.

[0059] Equipment: lightning protection unit, residual voltage detection unit, lightning counting unit and lightning sensing unit. The lightning protection unit is set on the 30-meter and 92-meter iron towers respectively, and each corresponding iron tower is equipped with a residual voltage detection unit. The base and surrounding areas A number of lightning counting units and a lightning sensing unit are installed inside. The lightning counting units are installed in the open area and on the iron tower, and the lightning sensing unit is installed on the 92-meter iron tower.

[0060] In mid-August 2017, there were three consecutive days of severe thunderstorms in the area where the base is located,...

Embodiment 2

[0079] 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.

[0080] A lightning protection unit is installed on the base of the top of Dengtashan, a lightning residual voltage detection unit is installed at the foot of the mountain, multiple lightning counter units are installed at the south, north and foot of the mountain, and a lightning sensing unit is installed under the lightning pro...

Embodiment 3

[0084] 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 flow 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.

[0085] Before March 2017, install a lightning protection unit at the top of each high-voltage transmission tower in the above line section, install a lightning residual voltage detection unit at the bottom of each high-voltage transmission tower, and install a lightning protection unit at the bottom of each high-voltage transmission tower. A lightning counter unit is installed on the side, and a lightning induction unit is installed on the top of the highest high-voltage transmission tower. A total of ten lightning protection units are used.

Abstract

The invention relates to a lightning protection system integrating lightning protection and recording, including a lightning protection unit, a residual voltage detection unit and a lightning countingunit. One lightning protection unit is arranged at the highest position of each lightning protection area. The lightning protection unit is connected with one residual voltage detection unit. At least one lightning counting unit is arranged in the lightning protection area. According to the invention, the lightning protection unit is installed at the top of the highest building within a protection scope, such as 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. Energy is accumulated by using equal-height lightning receiving rods arranged at the upper end, and charges are neutralized around the insulating medium, so that the thundercloud energy is consumed within the effective radiusaround the equipment, and no downlink discharge channel is formed. The residual voltage after lightning protection is less than or close to 120 volts and is extremely lower than the voltage released by lightning stroke under normal conditions. Therefore, the work safety of electrical equipment and communication facilities inside, outside and around the building is ensured.

Description

technical field [0001] The invention belongs to the technical field of lightning protection technology innovation, in particular to a lightning protection system integrating lightning protection and recording. Background technique [0002] Lightning is a natural phenomenon, which is very harmful to buildings and electronic equipment inside. When the lightning current flows through the struck object, it will cause the temperature of the struck object to rise, resulting in the damage of the struck object. Damage, the intense high temperature of the generated arc can also cause great damage to the object to be struck, and local metal melting and burning spots will be generated on the surface of the object to be struck, and the induced overvoltage will damage the control system or electronic devices of the object to be struck. Overvoltage is closely related to the steepness of lightning current, the greater the steepness of lightning current, the higher the induced voltage. At ...
