Abstract

The invention provides a novel gas discharge tube for coaxial cables, and belongs to the technical field of lightning protection overvoltage. The novel gas discharge tube comprises a cylindrical cavity, wherein the cavity comprises a cavity wall and plugs at the upper end and the lower end; an inert gas is arranged in the cavity; the cavity is connected to the coaxial cables in series through a metal shell; two ends of the metal shell are connected to the coaxial cables at two ends through connectors respectively; an electrode is arranged in the cavity in a radial manner; two ends of the electrode pass through the upper plug and the lower plug respectively to be connected with wire cores of the coaxial cables at two ends; the cavity wall is an electric conductor; the metal shell is connected with a grounding plate; the cavity wall, the metal shell and the grounding plate form a ground terminal; and the upper plug and the lower plug are made of insulating materials. The novel gas discharge tube has the beneficial effects that the gas discharge tube can be connected to coaxial transmission cables in series and the characteristics of a higher transmission frequency bandwidth, a lower loss, high lightning discharge capacity, more excellent protection voltage, safety and reliability can be achieved.

Description

technical field [0001] The invention relates to the technical field of lightning strike overvoltage protection for cables, in particular to a gas discharge tube for coaxial cables. Background technique [0002] Lightning is very harmful to human beings, and the surge overvoltage induced by lightning pulses is very destructive to communication equipment. The coaxial cable lightning arrester is an indispensable protection device in microwave communication. It is connected to the transmitting antenna or receiving The coaxial cable between the antenna and the equipment in the computer room is used to eliminate the lightning surge pulse from invading the computer room, thereby avoiding damage to the communication equipment. The coaxial cable lightning arrester must be able to filter the lightning current on the one hand, and at the same time, it must not have other influences on the transmitted communication signals. At present, the core component of the coaxial cable lightning ...
