Embodiment Construction

[0019] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 The structure schematic diagram of the present invention is shown, a gas discharge tube with trigger electrodes, including 2 main discharge electrodes 1 and 5, 3 trigger electrodes 2, 3, 4 and 4 ceramic tubes 6. The two main discharge electrodes are arranged at both ends of the gas discharge tube, and the three trigger electrodes are arranged in sequence between the two main discharge electrodes, and between adjacent electrodes (the electrodes here refer to the main discharge electrodes and the trigger electrodes) They are connected by ceramic tubes filled with inert gas argon.

[0021] Such as figure 2 The schematic diagram of the structure of the main discharge electrode in the present invention is shown, including (a), (b), (c) 3 figures, respectively the front view, left view and right view of the main dischar...

Abstract

The invention discloses a gas discharge tube with trigger electrodes. The gas discharge tube comprises two main discharge electrodes, the n trigger electrodes and n+1 ceramic tubes, wherein n is larger than or equal to one, the two main discharge electrodes are arranged at the two ends of the gas discharge tube, the n trigger electrodes are sequentially arranged between the two main discharge electrodes, every two adjacent electrodes are connected through the corresponding ceramic tube, and the ceramic tubes are filled with inert gas. By means of the gas discharge tube, the problems of the long response delay and the large follow current of an existing gas discharge tube are solved, and the lightning protection effect is improved.

Description

technical field [0001] The invention belongs to the technical field of lightning protection, and in particular relates to a gas discharge tube with a trigger electrode. Background technique [0002] The gas discharge tube is a gap type lightning protection component, which has been widely used in the lightning protection of the communication system. The gas discharge tube plays the role of discharging lightning transient overcurrent and limiting overvoltage. Due to the large insulation resistance between the electrodes of the discharge tube, under the distributed capacitance, it has obvious advantages in lightning protection for high frequency and microwave signals. The working principle of the discharge tube is gas discharge. When a certain voltage is applied between the electrodes, an uneven electric field will be generated between the electrodes, and the gas between the electrodes will start to dissociate under the action of the electric field. When the dielectric stren...
