Circular helical-line radio-frequency lightning protection method and lightning protection device

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.
