Discharge tube with parallel connection of multiple discharge chambers and manufacturing method thereof

Abstract

The present invention provides a discharge tube with parallel connection of multiple discharge chambers and a manufacturing method thereof. The discharge tube comprises an insulation body, two ends ofthe insulation body are respectively provided with discharge electrodes, and the insulation body is provided with a plurality of discharge chambers which penetrate the insulation body and are connected with the discharge electrode at the two ends. The manufacturing method comprises the following steps of: S1, preparing insulation body materials: getting ceramic powder, plastic particles and a fire retardant; S2, processing the insulation body materials: performing weighing, stirring, grinding and homogenization of components; S3, forming the insulation body: employing a forming tool to extrude the processed insulation body materials to a flat plate; S4, forming the discharge chambers: employing a stamping mechanism to stamp the flat plate to form a porous structure and generate dischargechambers; and S5, bonding the discharge electrodes: putting the discharge electrodes at the two ends of the flat plate, employing a clamp to clamp the discharge electrodes, and putting the discharge electrodes into an oven to bond the discharge electrodes and the flat plate. The discharge tube with parallel connection of multiple discharge chambers and the manufacturing method thereof are simple in structure, easy to implement, long in service life and good in safety with parallel connection of multiple discharge chambers.

Description

technical field [0001] The invention belongs to the technical field of discharge tubes, in particular to a discharge tube with multiple discharge chambers connected in parallel and a manufacturing method thereof. Background technique [0002] When the gas discharge tube is under lightning strike or overvoltage protection, the gas discharge tube presents a low resistance state after being subjected to lightning strike or overvoltage. When there is an operating current in the equipment protected by the gas discharge tube, the operating current will flow into the gas discharge tube. The gas discharge will generate a continuous follower current. When it acts for many times or for a long time, it will cause the air gap to be polluted and short-circuited or melted or short-circuited, losing its original function, causing electrical circuit failure, and even burning, causing fires and other accidents. [0003] Therefore, there is a need for a discharge tube with multiple discharge ...
