计及杂散参数的柔性直流启动电阻冲击电压分布特性研究

Gaoya dianqi
针对柔性直流输电系统中启动电阻异常放电问题。首先，从启动电阻温升、绝缘水平、电流应力及冲击能量几方面进行校核分析；然后，对现场启动电阻进行拆解，定量分析启动电阻放电原因；最后，利用Ansys搭建电阻器杂散电容求解模型，根据分布电容求解结果，基于PSCAD搭建电阻塔的宽频等效模型，仿真分析启动电阻在冲击电压下的电位分布规律，验证启动电阻异常放电机理并提出优化改进措施。研究结果可为今后柔性直流输电系统启动电阻的选型设计提供参考。

阻容均压方式下双断口真空断路器预击穿特性研究

Gaoya dianqi
双断口真空断路器能够充分利用短真空间隙的优异绝缘性能，显著降低容性电流开合过程中的重击穿概率，提高投切电容器组的性能。文中通过实验研究了双断口真空断路器采用阻容均压方式时的预击穿特性，包括预击穿电压、预击穿开距及其分散性，并计算其威布尔分布。研究结果表明，无论电压幅值如何，高压电阻都可以通过阻断从均压电容流向真空灭弧室的放电电流来延缓击穿过程，显著提升了双断口真空断路器的预击穿特性。对于串联电阻和桥接电阻两种阻容均压方式，桥接电阻可以减少电路中使用的电阻数量，降低断路器成本和体积 ...
