摘要

在高压电器中，灭弧气体的应用十分广泛，气体的灭弧性能与其恢复特性息息相关。对于气体介质的灭弧性能测量，已有理论研究中的建模仿真方法以及一些直接或间接的测量电子密度的手段都存在较明显的缺点。为解决这一问题，文中通过Mach-Zehnder干涉法可以较为精确地测量出弧后各时间点的电子密度这一研究气体介质恢复特性的关键参数。同时考虑到断路器结构下新型气体介质测量成本高昂，文中设计了基于激光诱导等离子的气体介质恢复特性测量实验。通过该实验，对SF

、CO

和N

的电子密度衰减特性进行测量，其电子密度的衰减速率特征值为SF

Abstract

Arc extinguishing gas is used widely in high voltage apparatus

and arc extinguishing performance of the gas is closely related to its recovery performance. As for the measurement of arc extinguishing performance of gas medium

there are obvious shortcomings in modeling and simulation methods and some direct or indirect methods for measuring electron density. For solving this problem

the use of Mach-Zehnder interferometry can accurately measure the electron density at each time point behind the arc

which is a key parameter for studying the recovery characteristics of gas medium. At the same time

considering the high cost of the new gas medium measurement under the circuit breaker structure

a laser induced plasma based gas medium recovery characteristics measurement experiment is designed in this paper. Through this experiment

the electron

density attenuation characteristics of SF

and N

are measured

the characteristic value of decay rate of electron density is SF

(0.77)

(0.72)

and the feasibility of the proposed method is verified by comparing with the existing conclusion.
