Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0015] It can be seen from the accompanying drawings that the present invention relates to a circular helix radio frequency lightning protection method. The coaxial transmission line is placed in the outer conductor shell of the lightning arrester, and is supported by an insulating medium in the middle of the outer conductor shell to form a connection with the outer conductor. Conductor coaxial structure; in the middle of the coaxial transmission line, there is a conical compensation transmission coaxial line and a helical short-circuit line in series; and a gas discharge tube is installed between the helical short-circuit line and the outer conductor of the input end, and is separated by The conical compensation transmission coaxial line, the he...

Abstract

The invention relates to a circular helical-line radio-frequency lightning protection method and a lightning protection device. Coaxial transmission lines are arranged inside outer conductor shells of the lightning protection device, and the coaxial transmission lines are supported by insulation media on the middle parts inside the outer conductor shells to form coaxial structures with outer conductors; the middle of the coaxial transmission lines are serially connected with a conical compensation transmission coaxial line and a helical line-type short-circuit wire; gas discharging pipes are arranged between the helical line-type short-circuit wire and an input-end outer conductor to separate the helical line-typed short-circuit wire from the input-end outer conductor, and the conical compensation transmission coaxial line, the helical line-typed short-circuit wire and the gas discharging pipes form a feeding and lightning protection circuit; and the lightning protection can be realized through the lightning protection circuit with the feeding function. A plurality of radio-frequency systems can be simultaneously covered, and the normal work of third-generation (3G) radio-frequency receiving-transmitting system such as global system for mobile communication (GSM), code division multiple access (CDMA), time division-synchronous code division multiple access (TD-CDMA) and the like can be guaranteed; and at the same time, the short-circuit wire adopts a helical-line structure, the compensation coaxial wire adopts the conical design, and the input-end outer conductor and an output-end outer conductor are in a circular structure, so the size of the product is small, the product is simple and convenient to connect, the contact resistance is effectively reduced, and the transmission performance of the product is improved.

Description

technical field [0001] The invention relates to a novel lightning protection method and device, in particular to a circular spiral radio frequency lightning protection method and a lightning protection device. It belongs to the technical field of lightning protection. Background technique [0002] With the continuous development and innovation in the field of communication products, the integration of communication equipment is getting higher and higher, and the competition is becoming more intense. Communication equipment is usually installed in the open field or on the top of a building. It is easily damaged by induced lightning, causing damage to communication equipment and interruption of signals. In the information age, the impact on human life is also increasing. Heavy. [0003] With the progress of society, the main call function in the original wireless communication can no longer meet people's needs. People's call quality and multimedia functions in high-speed ope...
