摘要

寻求可替代SF

用于高压电气设备的气体是近年来的研究热点

而C

N气体由于具有较好的环保性能和优良的绝缘特性而极具潜力。然而受限于实验成本等原因

现阶段对于其灭弧性能的研究相对较少。通过仿真分析气体电弧行为能够为环保型开关的设计提供重要指导。文中首先分析了C

N、CO

和SF

3种气体电弧的物性参数及成因

基于此采用磁流体动力学方法建立了轴对称二维喷口电弧模型并进行了计算

获得了C

N、CO

和SF

中电弧等离子体的温度分布及对应燃弧情况下的电弧电压

结合电弧物性参数结果分析了3种气体燃弧特性的主要成因。研究发现

纯C

N气体的电弧半径与电弧电压均与SF

气体相近

相比于纯CO

气体表明了其作为灭弧介质的潜在应用前景。但由于C

N气体分子质量相对较高

后续C

N气体的电弧仿真需要对湍流参数进行进一步研究

并通过相应的实验进行验证。

Abstract

N gas has received wide attention as an alternative gas to SF

in recent years due to its good environmental performance and excellent insulation properties.However

since the study cost on the arc of C

N gas is higher

therefore

the analysis of its arc by w

ay of simulation and comparison with the arc property of SF

gas can provide important guidance for the design of environmentally environmentally friendly switches.In this paper

a twodimensional nozzle arc model is set up and calculated based on magnetohydrodynamic method and the temperature distribution of arc plasma in C

and SF

is obtained.It is found by the study that the arc radius of pure C

N gas is similar to that of SF

so C

N gas has potential application as an extinguishing medium.And the turbulence effect is still considered in the subsequent arc simulation of C

N gas.
