Gaoya dianqi电容器组投切断路器触头烧蚀劣化后会改变合闸预击穿时间，这不仅会影响选相合闸效果，同时也说明预击穿电弧持续时间可作为衡量触头烧蚀状态的指标之一。建立了126 kV SF6断路器灭弧室内合闸预击穿过程电—流体耦合仿真模型，研究了触头劣化过程中合闸预击穿特性，并提出了预击穿时间带电检测方法。结果表明：合闸过程中场强最大点总是出现在静弧触头表面；灭弧室内SF6气体密度几乎保持不变；110 kV电压等级相电压下，触头预击穿电弧持续时间随烧蚀程度变化的试验值与仿真值吻合良好 ...

Gaoya dianqi35 kV风电场架空集电线路多位于山岩地区，雷击跳闸率高，需要相应的防雷措施。目前，在山岩地区降低接地电阻困难，成本高，接地电阻值难以达标。文中研究了35 kV风电场架空集电线路的等效降阻防雷措施。结果表明，架设耦合地线时，耐雷水平可以达到接地电阻为5Ω时的水平；当35 kV集电线路安装线路避雷器时，雷击避雷线GJ-100、雷击避雷线OPGW、雷击导线时耐雷水平的提升幅度分别为8.23、7.86、70.8倍，对比降低接地电阻有更显著的提升效果。该研究将在35 ...

Gaoya dianqi磁开关具有高重频、长寿命和高平均功率等优点，能够实现脉冲前沿的压缩，已广泛应用于脉冲功率系统。目前磁开关的设计是采用伏秒积分方程确定磁芯结构体积以及绕组的匝数，设计时的精度不高。通过测量铁基纳米晶磁芯的脉冲磁化特性，据此使用多物理场仿真软件Comsol建立了考虑磁芯饱和过程的磁开关场路耦合模型，通过100 kV级的高压脉冲压缩实验，验证了仿真模型的准确性与有效性。利用磁开关仿真模型分析了磁芯的饱和时间以及杂散参数对磁开关输出波形的影响，完成了磁芯饱和时间以及减小磁开关杂散参数的优化设计 ...
