Abstract

The external insulation of the equipment in the valve hall of ultra high voltage (UHV) dc converter station must be able to withstand ac-dc combined voltage influences. Investigating the surface discharge characteristics of external insulation under ac-dc combined voltage is currently a significant research topic. The investigation into the surface streamer characteristics under ac-dc combined voltage is instrumental in elucidating the mechanism of surface flashover. The streamer characteristics of different phases in a single cycle under ac-dc combined voltage were determined by conducting surface streamer discharge tests. The relationship between surface streamer characteristics and different phases under ac-dc combined voltage was summarized. By comparing the test results of surface streamer discharge under dc voltage, this study analyzed the effect mechanism of ac-dc combined voltage on surface streamer characteristics. The directional motion of space charge under ac-dc combined voltage was identified as the primary determinant of surface streamer characteristics.

交直流复合电压下表面流线型放电特性研究

特高压直流换流站阀厅内设备的外绝缘必须能够承受交直流组合电压的影响。研究交直流复合电压下外绝缘的表面放电特性是当前一个重要的研究课题。研究交直流复合电压作用下的表面闪络特性，有助于阐明表面闪络的机理。通过表面流光放电试验，确定了交直流复合电压下单周期内不同相位的流光特性。总结了交直流复合电压下表面流光特性与不同相位的关系。通过对比直流电压下表面流线型放电试验结果，分析交直流组合电压对表面流线型特性的影响机理。交直流复合电压作用下空间电荷的定向运动是影响表面流光特性的主要因素。
