Problems solved by technology

[0003] Existing detections for gas discharge tubes focus on performance parameters, without research on the three characteristics of gas discharge tubes, lack of multi-functional discharge circuits with three discharge characteristics detection, and taking into account batch experiments and multi-occasion tests. At present, There is a lack of modular and portable experimental devices with the above functions, which leads to problems such as low reliability of results, low efficiency, and limitations of detection occasions in the detection of gas discharge tubes.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a multifunctional modular gas discharge tube test circuit and device. Background technique [0002] As a gap-type lightning protection component, the gas discharge tube has been widely used in the lightning protection of the signal system. However, lightning strikes often cause circuit overvoltage in the signal system, and the gas discharge tube will fail due to multiple discharges or long-term glow, which will cause the surge current in the signal system to fail to discharge, reducing the reliability of the signal system and security. Therefore, based on different short-circuit failure conditions, research on the arc discharge characteristics, glow discharge characteristics and arc-glow combined discharge characteristics of gas discharge tubes is crucial to the design and improvement of gas discharge tubes, and to improve the safety and reliability of signal system...
