真空灭弧室已被广泛应用于有载分接开关中,作为其实现切换的主要开合单元。换流变压器中应用的有载分接开关存在受谐波影响的运行工况,而目前针对真空灭弧室在谐波电流条件下的电弧等离子特性的研究尚属空白。因此,文中针对换流变压器应用的真空有载分接开关中的真空灭弧室开展相应的谐波电流条件下的电弧特性仿真,通过建立物理模型、数学模型及边界条件分析了真空灭弧室在谐波电流条件下的离子数密度、轴向电流密度、电子和离子温度等特征,并与工频电流条件下相应的特征进行了对比分析。获得的关于初始电流上升率、触头烧蚀、电弧密度、温度特性等方面对开断性能影响的研究结果将对真空型有载分接开关谐波电流切换能力的分析提供技术帮助。
Vacuum interrupter has been used widely in on-load tap-changer as the main units for its switching operations. The on-load tap-changers used in converter transformer are subjected to operating conditions affected by harmonics
yet research on the arc plasma characteristics of vacuum interrupter under harmonic current conditions remains lacking. Therefore
in this paper the simulation of the arc characteristic under harmonic conditions for the vacuum interrupter used in the vacuum type on-load tap changer of converter transformer is performed. By setting up physical model
mathematical model and boundary conditions
such parameters as ion number density
axial current density
electron and ion temperature within the vacuum interrupter used in the converter transformers under harmonic current conditions are analyzed. Furthermore
a comparative analysis is conducted on the corresponding characteristics under power frequency current conditions. The findings regarding the influence of such factors as initial current rise rate
contacts ablation
arc density and temperature characteristics on the interrupting performance will provide technical support for analyzing the harmonic current switching capability of vacuum type on-load tapchangers.
