Problems solved by technology
In case of a thunderstorm, a large amount of positive and negative charges are generated in the cloud. When the positive and negative clouds meet, it is easy to form lightning. If the lightning strike is transmitted to the antenna, it will instantly release a large current of tens of thousands of amperes, which is easy to damage the antenna. Breakdown of the various parts of the antenna will cause the antenna to fail or the performance of the antenna will deteriorate. Therefore, it is necessary to install a lightning protection device for the antenna

The invention provides a lightning protection device, a manufacturing method thereof, and a lightning protection antenna, which belong to the technical field of communication. The lightning protection device provided by the present invention is arranged on the antenna to prevent the antenna from being damaged by the lightning current. The lightning protection device includes a breakdown prevention structure and a drainage structure. Wherein, the anti-breakdown structure includes stacked multi-layer insulating layers, which are arranged on the antenna, and are used to prevent the antenna from being broken down by lightning current. The draining structure is arranged on the anti-breakdown structure, and is used for draining the lightning strike current to the ground. Since the anti-breakdown structure is arranged on the antenna, it can prevent the antenna from being punctured by lightning current, and because the drainage structure is provided, if the antenna is struck by lightning, the drainage structure can lead the lightning current to the ground to prevent the lightning current from damaging the antenna.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a lightning protection device, a manufacturing method of the lightning protection device and a lightning protection antenna. Background technique [0002] Antennas are generally set at a higher position of a building or even at the top of a building, and are used to receive and transmit electromagnetic signals. In case of a thunderstorm, a large amount of positive and negative charges are generated in the cloud. When the positive and negative clouds meet, it is easy to form lightning. If the lightning strike is transmitted to the antenna, it will instantly release a large current of tens of thousands of amperes, which is easy to damage the antenna. Breakdown of the various components of the antenna will cause the antenna to fail or the performance of the antenna will deteriorate. Therefore, it is necessary to install a lightning protection device for the antenna...
