摘　　要：在分析高压直流塑料电缆的衰减色散特性、脉冲电场耦合方式以及电极系统的基础上,论述了高压直流塑料电缆空间电荷测量系统。利用此测量系统测量了直流塑料电缆在24 h冷热循环条件下的空间电荷分布情况,实验结果可靠。Based on the analysis of the attenuation and dispersion properties of HVDC plastic cables, coupling mode of pulsed electric field, as well as the electrode system, this paper describes the space charge measurement system for HVDC plastic cables. Then the system is experimented to measure the space charge distribution of HVDC plastic cables under the condition of 24-hour thermal cycling, and the experiment result is proved reliable.
