Gas arcing characteristic and arc extinguishing performance multi-parameter detection system and method

Abstract

The invention discloses a gas arcing characteristic and arc extinguishing performance multi-parameter detection system and method. The multi-parameter detection system comprises a gas arc switch-on and switch-off experiment table, a multi-parameter detection module used for synchronously detecting a plurality of physical parameters of a gas arc and outputting corresponding detection signals in thegas arc on-off process, a comprehensive control system used for providing a control signal for the gas arc switch-on and switch-off experiment table and providing a detection trigger signal for the multi-parameter detection module, a signal conditioning module used for conditioning the first group of detection signals output by the multi-parameter detection module, a data acquisition module usedfor receiving the second group of detection signals output by the multi-parameter detection module and the first group of detection signals conditioned by the signal conditioning module. Through one-time arc switch-on and switch-off experiments, one-time unified measurement of multiple physical parameters in the gas arcing and arc extinguishing processes is achieved, and gas arc characteristics and the arc extinguishing performance can be mastered comprehensively from various aspects.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a multi-parameter detection system and method for gas arcing characteristics and arc extinguishing performance. Background technique [0002] Gas insulation / arc extinguishing has good self-recovery ability, and has the advantages of stable permittivity, small dielectric loss, non-flammable, non-explosive, good chemical stability, no aging, and cheap price, so gas insulation / arc extinguishing medium is widely used in in electrical equipment. Commonly used gas insulation / arc extinguishing materials include air, nitrogen, hydrogen, carbon dioxide, sulfur hexafluoride, etc. At the same time, people are still exploring gas insulation / arc extinguishing materials with better comprehensive performance. One of the key issues is how to quickly and systematically evaluate the arcing characteristics and arc-extinguishing performance of gases, which has great engineering value and theo...
