Comparison of Surge Voltage Reduction and Economic Efficiency of DC SSCBs According to MOV and RCD Snubber Combination

IEEE Open Journal of the Industrial Electronics Society
Metal oxide varistor (MOV) is a nonlinear resistive element whose resistance decreases rapidly when the applied voltage exceeds a threshold value. A dc solid-state circuit breaker (SSCB) uses MOVs or MOV with resistor-capacitor-diode (RCD) snubber ...

不同介质中MOV小电流特性的对比研究

Dianci bileiqi, 2006
氧化锌电阻片（MOV）常用于过电压保护,其小电流特性决定了它的工频稳定性。随着电力技术的发展,MOV被应用于变压器绕组内部和超导电力系统中,MOV的工作介质为变压器油和液氮。将MOV在空气和变压器油、空气和液氮（77K）中分别进行对比试验,通过小波变换对原始数据进行去噪,利用各次谐波法提取阻性电流进行对比分析,结果显示:MOV在变压器油中的阻性电流峰值大于空气中的值,MOV在液氮中的晶界电容、阻性电流峰值均小于空气中的值。表明MOV的小电流特性在空气中优于变压器油中,在液氮温区优于常温下。

MOA中MOV柱的温度分布研究 附视频

Dianci bileiqi, 1994
介绍了ＭＯＶ柱热路计算图，计算研究了ＭＯＶ柱的温度分布；并叙述了ＭＯＶ柱温度测量方法，试验研究了ＭＯＶ柱的温度分布。结果表明；计算与实测结果十分吻合。文中研究的ＭＯＶ柱热路图及测试方法可用于分析任何结构形式的ＭＯＡ温度分布；指出了ＭＯＶ柱温度是大值在靠近柱的上端部以及改善ＭＯＶ柱温度分布的结构措施，强调指出屏蔽措施不仅能使电场均匀化，而且能使热场（温度分布）均匀化，本研究对ＭＯＡ热设计具有参考意义。
