中文摘要:
      高压直流输电换流阀用饱和电抗器的磁芯工作于脉冲磁化工况,其分析和设计需要获得脉冲励磁下的磁特性参数. 借助磁脉冲压缩法思路,利用二阶振荡电路测量其脉冲磁化特性参数,得到了脉冲激励下的初始磁化曲线和磁滞回线. 利用测量结果计算其等效电感、 饱和时间及磁芯在一个周期内的耗能,分析磁化速率对磁芯耗能的影响.
英文摘要:
      The working condition of HVDC converter valve’s saturable reactor is micro-second pulse excitation. In the design of the magnetic core,the magnetic characteristics under fast pulse magnetization need. In order to obtain the initial magnetization curve of B-H and hysteresis loop,the magnetic characteristics under fast pulse magnetization is measured by using RLC resonant circuit. The equivalent inductance,saturated time and energy dissipation of magnetic core in one cycle are calculated by the measured results. The magnetizing rate has influence on the energy dissipation of the core. The characteristics are of great significance to the optimal design of saturable reactor.
